Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of priority to Korean Patent Application No. 10-2022-0066113, filed in the Korean Intellectual Property Office on May 30, 2022, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a heating system and a method for controlling a supply air temperature thereof.

BACKGROUND

In general, a heating system is applied to a heating appliance which burns gas or the like and heats air, thus performing heating control depending on an operation environment. As an example, the heating appliance may correspond to an air handling unit or the like.

Such a heating system determines a supply air setting temperature depending on a ventilation temperature, circulating air volume, and the capacity of the heating system and performs heating control based on the determined supply air setting temperature.

As a ventilation temperature increases when heating is continuously performed, because a supply air temperature increases together, a heating system which does not subdivide calorific adjustment repeats ON/OFF at a short period as the supply air temperature reaches a supply air setting temperature in a short time. As such, when the heating system repeats ON/OFF at the short period, heating performance of the heating system may be degraded and durability of a part or the like may be degraded.

Meanwhile, a heating system which subdivides calorific adjustment may continuously perform burning for heating with low calorie. However, when the heating system continues performing burning for a long time, durability of a burner or the like may be degraded.

Such terms as those defined in a generally used dictionary are to be interpreted as having meanings equal to the contextual meanings in the relevant field of art, and are not to be interpreted as having ideal or excessively formal meanings unless clearly defined as having such in the present application.

FIG. 1 is a block diagram illustrating a configuration of a heating system according to an embodiment of the present disclosure.

The heating system may collect state information in real time or at a certain period while a heating appliance performs heating control to monitor the collected state information, may compare a heating burning time of the heating appliance with a predetermined allowable burning time based on the identified state information, and may variably control a supply air setting temperature of the heating appliance depending on the compared result. As an example, the heating appliance may be an air handling unit having a heating function.

Referring to FIG. 1, a heating system 100 may include a controller 110, a communication device 120, storage 130, and a state monitoring device 140.

The controller 110 may be a hardware device, such as a processor or a central processing unit (CPU), or may be a program implemented by a processor. The controller 110 may be connected with respective components of the heating system 100 to perform an overall function for controlling a supply air temperature.

The communication device 120 may receive state information obtained by sensors while the heating appliance is running. As an example, the state information may include information such as a ventilation temperature, circulating air volume, or a heating burning time.

The storage 130 may store data, an algorithm, and/or the like necessary for an operation of the heating system 100. As an example, the storage 130 may store state information of the heating appliance, which is received from respective sensors while the heating appliance is operating. Furthermore, the storage 130 may store conditions predetermined for controlling a supply air temperature of the heating appliance, an algorithm, and/or the like.

Herein, the storage 130 may include a storage medium such as a random access memory (RAM), a static RAM (SRAM), a read-only memory (ROM), a programmable ROM (PROM), or an electrically erasable PROM (EEPROM).

When the heating control of the heating appliance starts, the state monitoring device 140 may monitor state information received through the communication device 120 in real time. Herein, monitoring the state information in real time may include monitoring the state information at intervals of a predetermined certain time period, other than monitoring the state information in a continuous time.

As an example, when heating control starts, the state monitoring device 140 may monitor a heating burning time while heating burning control in one cycle is performed in real time. Furthermore, when the heating burning control in the one cycle ends, the state monitoring device 140 may monitor a total heating burning time during the cycle.

The controller 110 may control an operation of the state monitoring device 140 when the heating control starts and may variably control a supply air setting temperature when the monitored result of the state monitoring device 140 meets a supply air temperature compensation condition.

As an example, when the heating burning time while the heating burning control in the one cycle is performed is greater than a predetermined allowable burning time, the controller 110 may determine that a first condition for supply air temperature compensation is met. In this case, the controller 110 may upwardly adjust the supply air setting temperature.

Herein, the allowable burning time refers to a time when continuous burning is allowed upon heating burning. When the allowable burning time is set to a certain time range, the controller 110 may determine whether the heating burning time while the heating burning control in the one cycle is performed is greater than a maximum time (or a maximum allowable burning time) in the certain time range set to the allowable burning time. While the heating burning time during the one cycle is greater than the predetermined allowable burning time, because a problem in a burner or the like is able to occur as burning continues for a long time, a heating burning time should be reduced.

Thus, when the supply air setting temperature is upwardly adjusted, a heating burning time may be shortened as a supply air temperature increases upon heating burning.

The controller 110 may perform supply air temperature compensation with respect to a time point when the heating burning time is greater than the predetermined allowable burning time while the heating burning control in the one cycle is performed.

At this time, the controller 110 may upwardly adjust the supply air setting temperature by a correction temperature and may then identify whether heating burning ends during a predetermined time T. When the heating burning does not end during the predetermined time T after upwardly adjusting the supply air setting temperature by the correction temperature, the controller 110 may upwardly adjust the supply air setting temperature by the correction temperature again. In such a manner, the controller 110 may upwardly adjust the supply air setting temperature by the correction temperature at intervals of the predetermined time T until the heating burning the cycle ends.

When the heating burning ends, the controller 110 may stop the supply air temperature compensation such that heating burning in a next cycle is performed by the heating appliance after a certain time elapses.

Thus, a description will be given in detail of a supply air temperature compensation operation for upwardly adjusting the supply air setting temperature with reference to an embodiment of FIG. 2.

FIG. 2 is a drawing referenced to describe an operation of controlling a supply air temperature of a heating system according to an embodiment of the present disclosure. The embodiment of FIG. 2 indicates a supply air temperature compensation operation for upwardly adjusting a supply air setting temperature.

Referring to FIG. 2, t1 refers to a heating burning time identified during heating burning in a first cycle, and t2 refers to a heating burning time in a second cycle. Assuming that t2 is a predetermined allowable burning time, t1 is greater than the allowable burning time.

When the heating burning time is greater than the allowable burning time, a problem in a burner or the like may occur due to burning for a long time. Thus, a controller 110 of FIG. 1 may compensate for a supply air setting temperature during burning to prevent a heating burning time in one cycle from being greater than the allowable burning time.

As an example, the controller 110 may identify the heating burning time t1 in real time during heating burning in the first cycle and may upwardly adjust a supply air temperature by a correction temperature to compensate for the supply air setting temperature, when the identified heating burning time t1 is greater than the predetermined allowable burning time. At this time, when the supply air setting temperature is upwardly adjusted, a heating burning time may be shortened as a supply air temperature increases.

When the heating burning does not end although a predetermined time T elapses after upwardly adjusting the supply air setting temperature, the controller 110 may upwardly adjust the supply air setting temperature by the correction temperature again. Herein, T is a predetermined time, which refers to a supply air temperature compensation period. As an example, T may be a time of an optimal period obtained to variably control a supply air setting temperature through a pre-test or the like.

In the embodiment of FIG. 2, the controller 110 may identify that heating burning ends after upwardly adjusting the supply air setting temperature two times during 2T after a time point when the heating burning time t1 identified during the first cycle is greater than the allowable burning time.

Thereafter, the controller 110 may perform a heating burning operation based on the supply air setting temperature previously set during the first cycle in the second cycle, thus identifying that the heating burning time decreases by t2 from t1.

At this time, because the heating burning time t2 in the second cycle corresponds to the predetermined allowable burning time, the controller 110 does not compensate for the supply air setting temperature and starts heating control in a next cycle after a certain time when the second cycle ends.

As another example, when heating burning control in one cycle ends, the controller 110 may identify a heating burning time monitored by a state monitoring device 140 of FIG. 1. When a final heating burning time during the cycle is less than the allowable burning time after the cycle ends, the controller 110 may determine that a second condition for supply air temperature compensation is met. In this case, the controller 110 may downwardly adjust the supply air setting temperature.

Herein, the allowable burning time refers to a time when continuous burning is allowed upon heating burning. When the allowable burning time is set to a certain time range, the controller 110 may determine whether the final heating burning time is less than the allowable burning time with respect to a minimum time in the certain time range set to the allowable burning time. When the heating burning time during one cycle is less than the predetermined allowable burning time, as ON/OFF is frequently repeated upon heating, a problem in durability of the system may occur and heating efficiency is able to be degraded due to this. In this case, the controller 110 should increase the heating burning time.

Thus, when the supply air setting temperature is downwardly adjusted, as the supply air temperature decreases upon heating burning, the heating burning time may increase.

Thus, after heating burning in one cycle ends, when the heating burning time during the cycle is less than the predetermined allowable burning time, the controller 110 may perform supply air temperature compensation.

At this time, the controller 110 may downwardly adjust the supply air setting temperature by a correction temperature, such that heating burning control is performed based on the downwardly adjusted supply air setting temperature when a next cycle starts.

Thereafter, when the heating burning in the next cycle ends, the controller 110 may identify a heating burning time during the cycle and may perform supply air temperature compensation again when the identified heating burning time is less than the predetermined allowable burning time. At this time, the controller 110 may downwardly adjust the supply air setting temperature by the correction temperature, such that heating burning control is performed based on the downwardly adjusted supply air setting temperature when a next cycle starts.

Of course, after the heating burning in the next cycle ends, when the heating burning time during the cycle is greater than or equal to the predetermined allowable burning time, the controller 110 does not perform supply air temperature compensation.

Thus, a description will be given in detail of a supply air temperature compensation operation for downwardly adjusting the supply air setting temperature with reference to an embodiment of FIG. 3.

FIG. 3 is a drawing referenced to describe an operation of controlling a supply air temperature of a heating system according to another embodiment of the present disclosure. The embodiment of FIG. 3 indicates a supply air temperature compensation operation for downwardly adjusting a supply air setting temperature.

Referring to FIG. 3, t1 refers to a heating burning time in a first cycle, t2 refers to a heating burning time in a second cycle, and t3 refers to a heating burning time in a third cycle. Assuming that t3 is a predetermined allowable burning time, t1 and t2 do not even reach the allowable combustion time.

As such, when the heating burning time during one cycle is less than the allowable burning time, as ON/OFF is frequently repeated during heating control, this causes a durability problem of the system and heating efficiency may be degraded due to this. Thus, the controller 110 may compensate for a supply air setting temperature after a burning control operation in one cycle ends to prevent ON/OFF from being frequently repeated as the heating burning time during the one cycle is less than the allowable burning time.

As an example, the controller 110 may identify a heating burning time t1 after heating burning during the first cycle ends and may downwardly adjust the supply air setting temperature by a correction temperature to compensate for the supply air setting temperature, when the identified heating burning time t1 is less than the predetermined allowable burning time. At this time, when the supply air setting temperature is upwardly adjusted, as a supply air temperature decreases, a heating burning time may increase.

When the second cycle starts after downwardly adjusting the supply air setting temperature, the controller 110 may identify the heating burning time t2 after heating burning during the second cycle ends. Thereafter, the controller 110 may perform a heating burning operation based on the supply air setting temperature previously set during the first cycle in the second cycle, thus identifying that the heating burning time increases by t2 from t1.

However, when the heating burning time t2 identified during the second cycle is less than the predetermined allowable burning time, the controller 110 may downwardly adjust the supply air setting temperature by the correction temperature again to compensate for the supply air setting temperature. At this time, when the supply air setting temperature is downwardly adjusted, as the supply air temperature decreases, the heating burning time may further increase.

Likewise, when the third cycle starts after downwardly adjusting the supply air setting temperature, the controller 110 may identify the heating burning time t3 after heating burning during the second cycle ends. In this case, the controller 110 may perform a heating burning operation based on the supply air setting temperature previously set during the second cycle in the third cycle, thus identifying that the heating burning time increases by t3 from t2.

At this time, because the heating burning time t3 in the third cycle corresponds to the predetermined allowable burning time, the controller 110 does not compensate for the supply air setting temperature and starts heating control in a next cycle after a certain time.

A description will be given in detail of operational flow of the heating system according to an embodiment of the present disclosure, having the above-mentioned configuration.

FIG. 4 is a drawing illustrating operational flow of a method for controlling a supply air temperature of a heating system according to an embodiment of the present disclosure. The embodiment of FIG. 4 indicates a control operation when a heating burning time is greater than a predetermined allowable burning time.

Referring to FIG. 4, when burning starts depending on a heating request in S110, a heating system 100 of FIG. 1 may identify a heating burning time in real time. At this time, the heating system 100 may identify the heating burning time at intervals of a certain time. Herein, the heating system 100 may continue identifying the heating burning time until the heating burning ends.

The heating system 100 may determine whether the heating burning time is greater than the predetermined allowable burning time. Because a problem in a burner or the like is able to occur when burning continues to be greater than the allowable burning time, the heating system 100 may continue determining whether the heating burning time is greater than the allowable burning time while the heating burning continues. Herein, the allowable burning time refers to a time when continuous burning is allowed, which may be set to a specific time value or may be set to a certain time range. When the allowable burning time is set to the certain time range, the heating system 100 may determine whether the heating burning time is greater than the allowable burning time with respect to a maximum time in the certain time range set to the allowable burning time while heating burning in one cycle continues.

When the heating burning time is not greater than the allowable burning time in S120, the heating system 100 may continue performing S120 until the heating burning ends.

Meanwhile, when the heating burning time identified during the heating burning is greater than the allowable burning time in S120, in S130, the heating system 100 may upwardly adjust a supply air setting temperature by a correction temperature. At this time, when a supply air temperature increases, because the heating burning time is able to be shortened by the increased supply air temperature, the heating system 100 may upwardly adjust the supply air setting temperature by the correction temperature to shorten the heating burning time. Herein, the correction temperature may be a predetermined value.

The heating system 100 may perform heating control based on the supply air setting temperature upwardly adjusted in S130. Thereafter, when the heating burning ends within a predetermined time T in S140 to S160, the related operation may end.

Meanwhile, after S130, when the heating burning does not end during the predetermined time T, in S130, the heating system 100 may upwardly adjust the supply air setting temperature previously set in S130 by the correction temperature again. Herein, the predetermined time T may be a time of an optimal period obtained to variably control the supply air setting temperature through a pre-test or the like. Thereafter, the heating system 100 may perform heating control based on the supply air setting temperature upwardly adjusted by the correction temperature.

As such, the heating system 100 may upwardly adjust the supply air setting temperature by the correction temperature at intervals of the predetermined time T until the heating burning ends. Thereafter, when the heating burning ends in S150 and S160, the heating system 100 may end a heating control operation in the cycle.

The process of S110 to S160 may correspond to a heating burning operation in one cycle during the heating control. When a heating burning operation in a next cycle starts after a certain time elapses, the process of S110 to S160 may be repeatedly performed again.

As the embodiment of FIG. 4, when the heating burning time continues for a long time, the heating system 100 according to an embodiment of the present disclosure may upwardly adjust the supply air setting temperature to reduce the heating burning time, thus preventing the burner or the like from being damaged.

FIG. 5 is a drawing illustrating operational flow of a method for controlling a supply air temperature of a heating system according to another embodiment of the present disclosure. The embodiment of FIG. 5 indicates a control operation when a heating burning time is less than a predetermined allowable burning time.

Referring to FIG. 5, in S210, a heating system 100 of FIG. 1 may start burning depending on a heating request. Thereafter, after heating burning in one cycle ends in S220, the heating system 100 may identify a heating burning time during the one cycle. Herein, the heating system 100 may identify the heating burning time until the heating burning ends after the heating burning starts.

At this time, the heating system 100 may determine whether the heating burning time is less than the predetermined allowable burning time. When heating burning in one cycle ends less than the allowable burning time, as ON/OFF is frequently repeated during heating control, because this causes a durability problem of the system and heating efficiency is able to be degraded due to this, the heating system 100 may determine whether the heating burning time during the one cycle is less than the allowable burning time whenever the heating burning in the cycle ends. Herein, the allowable burning time refers to a time when continuous burning is allowed, which may be set to a specific time value or may be set to a certain time range. When the allowable burning time is set to the certain time range, the heating system 100 may determine whether the heating burning time is less than the allowable burning time with respect to a minimum time (or a minimum allowable burning time) in the certain time range set to the allowable burning time after the heating burning in the one cycle ends.

When the heating burning time is not less than the allowable burning time in S230, the heating system 100 waits until heating burning in a next cycle starts.

Meanwhile, when the heating burning time is less than the allowable burning time in S230, in S240, the heating system 100 may downwardly adjust a supply air setting temperature by a correction temperature to increase the heating burning time to be longer. At this time, when a supply air temperature decreases, the heating burning time is able to increase by the decreased supply air temperature, the heating system 100 may downwardly adjust the supply air setting temperature by the correction temperature to increase the heating burning time to be longer. Herein, the correction temperature may be a predetermined value.

Thereafter, the heating system 100 may perform control in S210 to S240 based on the supply air setting temperature downwardly adjusted by the correction temperature in a next cycle.

Even upon the heating control in the next cycle, when the heating burning time during the cycle is less than the allowable burning time, the heating system 100 may downwardly adjust the supply air setting temperature by the correction temperature again.

As the embodiment of FIG. 5, when the heating burning time in one cycle is too short, the heating system 100 according to an embodiment of the present disclosure may downwardly adjust the supply air setting temperature to increase the heating burning time, thus preventing an ON/OFF operation upon heating control from being frequently repeated.

According to an embodiment of the present disclosure, the heating system may follow an allowable burning time and may variably control a supply air setting temperature of a heating appliance, thus preventing ON/OFF from being repeated at a short period or preventing burning from continuing for a long time with low calorie to improve heating performance and durability.

Furthermore, according to another embodiment of the present disclosure, the heating system may perform heating control irrespective of a change in a heating environment element.

Hereinabove, although the present disclosure has been described with reference to exemplary embodiments and the accompanying drawings, the present disclosure is not limited thereto, but may be variously modified and altered by those skilled in the art to which the present disclosure pertains without departing from the spirit and scope of the present disclosure claimed in the following claims.
