Description

TECHNICAL FIELD

The present invention relates to an air-conditioning control system to perform air-conditioning in a space such as an office where multiple users are present, which can provide the multiple target users with a comfortable air-conditioned space by controlling multiple air-conditioning indoor units.

BACKGROUND ART

A general air-conditioning system operates the air conditioners to equalize the room temperature in the space. Patent Document 1, for example, discloses an invention to eliminate temperature unevenness by turning blowout panels of multiple indoor units toward a predetermined swirling direction to swirl the air of the entire room.

In contrast, such an air conditioning system is also used that can improve user's comfort by providing air-conditioning control only for a specific area in the space while achieving energy saving. Patent Document 2, for example, discloses a technique in which the space is segmented into “a presence area” where a user is present, “an absence area” where no user is present and “a boundary area” where the wind direction of an indoor unit is directed downward in order to generate an air curtain to keep the conditioning air in the presence area from outflowing into the absence area. Further, Patent Document 3 discloses a technique in which, when multiple users are present adjacently, a personal comfort level (PMV: Predicted Mean Vote) is calculated with respect to each of an air-conditioning requester and adjacent persons to generate a local airflow to the requester within a range not impairing the adjacent persons' PMVs, and thereby create an air-conditioned space in the area where the requester is present.

MODES FOR CARRYING OUT THE INVENTION

Embodiment 1

FIG. 1 is a block diagram of an air-conditioning system according to Embodiment 1 of the present invention. FIG. 2 is a plan view showing a positional relation of air-conditioning indoor units, users and sensors in a space. The air-conditioning control system 10 is a system to improve comfort of both of a target person and adjacent persons present in a space air-conditioned by multiple air-conditioning indoor units 41 to 44.

The air-conditioning control system 10 controls the indoor units 41 to 44 using information on the space, the users' settings, and information from the sensors. As shown in FIG. 1, the air-conditioning control system 10 can be realized by a general hardware configuration which includes: a CPU (Central Processing Unit) 31; a ROM (Read Only Memory) 32; a RAM (Random Access Memory) 33; a storage drive 34; an input/output controller 38 to connect a mouse 35 and a keyboard 36 provided as input devices and a display 37 provided as a display device; a network controller 39 provided as a communication means; and a bus 20 to connect them. Also, the air-conditioning control system is connected, via an air-conditioning control network 21, to vanes 41a to 44d of the air-conditioning indoor units 41 to 44, fans 41e to 44e thereof, compressors 45a to 48a of air-conditioning outdoor units 45 to 48, temperature sensors 51a to 51i, and air-conditioning controllers 52a to 52i. At least a part of the air-conditioning control network 21 may be a network which performs, for example, wireless communication.

First, the positions of the air-conditioning indoor units 41 to 44, the air-conditioning characteristics such as capacity of air conditioners, the positions of the sensors 51a to 51i, and the positions of the users are inputted using, for example, the mouse 35 and the keyboard 36, and stored in the storage drive 34 of the air-conditioning control system 10.

As shown in FIG. 2, the space is surrounded by walls. In the space, the air-conditioning indoor units 41 to 44 are arranged in a lattice. Each indoor unit includes multiple blowout openings and the vanes 41a to 44d installed at each blowout opening to change the blowout wind direction.

As shown in FIG. 2, the space is segmented into areas under the indoor units and areas between the indoor units. In each area, a single user is seated in each of seats arranged in a lattice, and the temperature sensors 51a to 51i and the air-conditioning controllers 52a to 52i are installed near the respective users. Although it is assumed here that one sensor and one air-conditioning controller are to be installed for each user, the number of them may be reduced to the number of users who want air-conditioning. Also, each sensor or controller may be replaced with a general personal computer (PC) or a user terminal such as a smartphone. Also, some area may include multiple seats and users.

FIG. 3 is a function block diagram of the air-conditioning control system 10 according to Embodiment 1. In FIG. 3, a first temperature setting unit 11, a second temperature setting unit 12, a first air-conditioning air control unit 13, and a second air-conditioning air control unit 14 are shown.

The functions of the first temperature setting unit 11, the second temperature setting unit 12, the first air-conditioning air control unit 13, and the second air-conditioning air control unit 14 shown in FIG. 3 are each realized by a combined usage of the CPU 31, the ROM 32, and the RAM 33 as hardware shown in FIG. 1.

In FIG. 3, the first temperature setting unit 11 sets a preset temperature for the air-conditioning target space for which a user has requested a change in the preset temperature. The second temperature setting unit 12 sets a preset temperature for adjacent air-conditioning spaces adjacent to the air-conditioning target space. In order to realize the preset temperature set by the first temperature setting unit 11, the first air-conditioning air control unit 13 sets a first blowout opening to blow out the air-conditioning air from among the multiple blowout openings of the multiple indoor units, and controls the temperature, the airflow volume, and the blowout wind direction of the air-conditioning air sent out from the first blowout opening. In order to realize the preset temperature set by the second temperature setting unit 12, the second air-conditioning air control unit 14 sets a second blowout opening to blow out the air-conditioning air from among the multiple blowout openings of the multiple indoor units, and controls the temperature, the airflow volume, and the blowout wind direction of the air-conditioning air sent out from the second blowout opening.

The second temperature setting unit 12 may set the preset temperature of the adjacent air-conditioning spaces so that the actual temperature change in the adjacent air-conditioning spaces will not exceed a predetermined range.

Next, taking a case of air cooling, the operation of the air-conditioning control system according to this Embodiment will be described. FIG. 4 is a side view for explaining the case and includes the users 51a to 51c and the indoor units 41 and 42. The operation flowchart is shown in FIG. 5.

When a seated user has specified a preset temperature, the first temperature setting unit 11 of the air-conditioning control system firstly determines that the space where the user having specified the preset temperature is present is a target area, and determines that spaces adjacent to the target space are adjacent areas, and then, sets a preset temperature regarded as an actual target temperature for the target area on the basis of the user-requested temperature.

Then, the air-conditioning control system collects temperature at each user's seat from the temperature sensor. If the temperature of the determined target area is different from the preset temperature, the air-conditioning control system operates to adjust the temperature to the preset temperature. Determining that in the adjacent area where a user is present and has not specified the preset temperature, the user has implicitly performed setting so as to make no change in the current temperature, the air-conditioning control system regards the current temperature as the preset temperature, and operates to adjust the temperature to the preset temperature.

FIG. 4 shows a case for example, in which the user 51b has specified the preset temperature, and in which the air-conditioning control system determines that the area where the user 51b is seated is a target area (target space), and determines that the areas where the adjacent users 51a and 51c are seated are adjacent areas (adjacent spaces).

Next, in order to adjust the temperature of the target area to the preset temperature, the first air-conditioning air control unit 13 of the air-conditioning control system determines the wind direction of the closest first blowout opening to the target area among the blowout openings facing thereto, and the change values of the blowout temperature and the airflow volume of the indoor unit which includes the closest first blowout opening. In FIG. 4, it is determined that the blowout opening 42a is the closest first blowout opening, and determination is made with respect to the wind direction of the first blowout opening and the change values of the temperature as well as the airflow volume of the indoor unit 42. The determination procedure of the change values of the first blowout opening will be described with reference to FIG. 6 below.

As shown in FIG. 7, the blowout air from the vanes 41a to 44d installed in respective blowout openings is directed, in a plane vertical to the floor, in a direction within the range of 0° to 90° with respect to the floor, and also is directed, in a plane parallel to the floor, in a direction within the range of −90° to 90°.

In setting the wind direction of the first blowout opening, the wind's depression direction θz and the wind's lateral direction θx are determined from the positions of the first blowout opening and the seat in the target area so that the wind blows against the seat, and then the angles of the vane 41 shown in FIG. 7 are changed to the determined angles.

In setting the airflow volume of the indoor unit which includes the first blowout opening, firstly the blowout speed of the air-conditioning air blown out from the first blowout opening which enables the air-conditioning air to reach the seat in the target area at a speed, for example, of 0.3 m/s or less is calculated from the relation between the airflow speed and the distance D from the first blowout opening to the position of the seat in the target area, and secondly the blowout airflow volume Va is calculated so as to satisfy the blowout speed.

The relation between the airflow volume Va from the blowout opening and the airflow speed Vs at the blowout opening, as well as the relation between the distance from the blowout opening and the airflow speed are, for example, derived from results of observed values obtained from an experiment in advance.

In the temperature settings of the indoor unit which includes the first blowout opening, the preset temperature of the indoor unit is calculated for the space of the current air temperature Tn, using the relation between the reaching distance D of the air blown out at the airflow volume of Va and the temperature change of the blowout air, and the temperature difference ΔT between the current temperature Tn at the seat position in the target area and the preset temperature Ts so that the temperature of the blown out air reaching the seat position in the target area will be Ts-ΔT degrees Celsius, which is the preset temperature reduced by the temperature difference.

The relation between the reaching distance D of the air blown out from the blowout opening and the temperature change of the blowout air is, for example, derived from results of observed values obtained from an experiment in advance.

The changed set values determined as above described for the first blowout opening of the indoor unit 42 in the case of FIG. 4 are shown in FIG. 8.

Next, the air-conditioning control system calculates temperature influence on the adjacent areas in a case where the air-conditioning settings are changed as described above. A target area under an indoor unit would influence less the surroundings. However, in a case where the target area is somewhat away from the first blowout opening, such as located between indoor units, the air-conditioning air blown out is diffused into an adjacent area close to the first blowout opening and an adjacent area in the side opposite to the first blowout opening with respect to the target area as shown in FIG. 4.

The second temperature setting unit 12 of the air-conditioning control system sets preset temperatures regarded as actual target temperatures for the adjacent areas on the basis of the calculation result.

The second air-conditioning air control unit 14 firstly calculates to find an adjacent area where the temperature change exceeds the predetermined temperature limit value, and next, determines the second blowout opening which is not the former mentioned first blowout opening and is closest to the adjacent area found by the calculation from among the blowout openings facing an intermediate spot between the adjacent area and the target area and then, determines the wind direction from the closest second blowout opening and the change values of the blowout temperature as well as of the blowout airflow volume of the indoor unit which includes the second blowout opening, so as to less influence the adjacent area and make the temperature become the preset temperature. In FIG. 4, the adjacent area where the user 51a is seated is an adjacent area determined to be influenced; the blowout opening 41c is determined to be the second blowout opening; and the wind direction of the blowout opening 41c and the change values of the temperature as well as the airflow volume of the indoor unit 41 are determined. With reference to FIG. 9, a determination procedure for changing values of the second blowout opening will be described below.

In setting the wind direction of the second blowout opening, a target position is determined whose horizontal position is the intermediate spot between the horizontal positions of the target area and the adjacent area and whose height is the same as the seat. Also the longitudinal wind direction θz and the lateral wind direction θx are determined in which the wind blows from the position of the second blowout opening to reach the target position.

In setting the airflow volume from the indoor unit which includes the second blowout opening, first the wind speed Vb at the target position is calculated from the wind speed at the first blowout opening and the relation between the distance from the blowout opening and the airflow speed, and then the airflow volume is computed so as to make the wind speed at the target position equal to the calculated wind speed.

In setting the temperature of the indoor unit which includes the second blowout opening, the preset temperature of the indoor unit is calculated from the relation between the temperature difference ΔTb from the current temperature, calculated as an influence to the adjacent area and the temperature change in the air which has been blown out at the airflow volume Va into the space of the current air temperature Tn and then reaches a position the distance Db away, so that when reaching the target position, the temperature becomes Tsb+ΔTb, which is the sum of the adjacent area's preset temperature Tsb and the temperature difference.

As described above, the changed set values of the second blowout opening of the indoor unit 41 have been determined in the case of FIG. 4, and the changed set values are shown together in FIG. 8.

Note that the set values of blowout openings other than the first blowout opening and the second blowout opening remain unchanged from the set values before the user performed temperature setting. These values are also shown in FIG. 8 as the values for other blowout openings.

The air-conditioning control system changes the settings of the air conditioners according to the set values of the first and the second blowout openings which are determined as described above. The angles of the vanes 41a to 44d are controlled to change the wind directions. The rotation speeds of the fans 41e to 44e of the air-conditioning indoor units are controlled to change the airflow volumes. When changing temperatures of the indoor units, the operation of the compressors and the outdoor units are controlled to change the temperatures of refrigerants and the flow amounts thereof in order to lower the blowout temperatures.

By the above-described control operation, not only the area under the indoor unit but also the areas between the indoor units can be controlled to create the desired air-conditioned spaces.

The above-described control operation can also prevent the local airflow to the target area from entering the adjacent areas, to create a desired air-conditioned space in the target area without impairing the comfort of the adjacent persons.

Embodiment 1 of the present invention has been described above. The concrete configuration for carrying out the invention, however, is not limited to the description.

The system described above has been explained in a case of air-cooling operation, but can similarly be applied to a case of heating operation.

In order to determine the blowout opening's wind direction and wind speed and the indoor unit's temperature, the relations among the distance from the blowout opening, the temperature and the wind speed have been derived from experimental results to be used. However, a method such as Airflow Simulation and CFD analysis (Computational Fluid Dynamics) may be used to calculate in more detail how the blown out air-conditioning air diffuses into and influences the target area and the surroundings.
