Abstract: A user enters a thermal perception level or a temperature set point in a perception level and temperature entry portion. Then, a clock portion calculates, by clocking, the time of entry to the perception level and temperature entry portion, and the entered temperature set point is stored as a temperature set point of an individual time interval in a temperature set point memory portion. When no entry is available to the perception level and temperature entry portion, air conditioning power is controlled in accordance with a temperature that has been already stored in the temperature set point memory portion.

Abstract: A user enters a thermal perception level or a temperature set point in a perception level & temperature entry portion (15). Then, a clock portion (16) calculates, by clocking, the time of entry to the perception level & temperature entry portion (15), and the entered temperature set point is stored as a temperature set point of an individual time interval in a temperature set point memory portion (18). When no entry is available to the perception level & temperature entry portion (15), air conditioning power is controlled in accordance with a temperature that has been already stored in the temperature set point memory portion (18).

Abstract: An air conditioner indoor unit comprising: a housing; an impeller arranged in the housing and forming a cross flow fan; a rear side plate arranged downstream the impeller and forming a rear side of a diffused air path; a front side plate forming a front side of the diffused air path and including a first air outlet surface, a second air outlet surface and a third air outlet surface; the first air outlet surface arranged near to the impeller and having a portion on a side of an air outlet of the diffused air path slanted in a direction away from a reference surface defined by the rear side plate; the second air outlet surface arranged next to the first air outlet surface on the side of the air outlet and having a portion on the side of the air outlet slanted in a direction away from the reference surface; and the third air outlet surface arranged next to the second air outlet surface on the side of the air outlet end and having a portion on the side of the air outlet slanted at 20.degree.-30.degree.

Abstract: An air conditioner for railway vehicles controlled in accordance with the air temperature in the car and data on at least one selected from the group consisting of underfoot temperature, radiant heat, air flow, humidity, outside air temperature, number of passengers and door opening operation. In this way, environment conditions which momentarily change are detected so as to prevent excessive cooling or heating in the car.

Abstract: An air conditioner having an indoor unit placed in a room to be heated or cooled, and a draft directing apparatus, such as a vertically tilting louver, which can assume a first position directing an outlet draft toward the location where a user is normally positioned, e.g., downward, and a wecond position directing the output draft away from said location, e.g., upward. The draft directing apparatus is controlled to assume the first position and the second position alternately, in such a manner that the proportion of the time for which the draft directing apparatus is in the first position is adjusted in accordance with the detected temperature of the draft. This adjusts the proportion of the time the draft is directed toward the user, and it is therefore possible to adjust the stimulation affecting the user.

Abstract: A heater comprising a heater body containing a heating source; an air blower for forcibly blowing off heated air from the heater body into a room, the heated air being produced by heat-exchanging with the heating source; a first temperature detection element for detecting a temperature at an upper level in the room; a second temperature detection element for detecting a temperature at a lower level in the room; a sensation input means for enabling a user to input his or her sensation corresponding to an actual room temperature; means for determining heating capability of the heating source based on the difference between the temperature detected by the first temperature detection element and a first set temperature; means for changing the outlet area and/or the air volume of the heated air based on the difference between the temperature detected by the second temperature detection element and a second set temperature lower than the first set temperature to determine the blow-off speed and/or the air volume of

Abstract: In an air flow control device for an air conditioner including a heat exchanger arranged so as to face an inlet port, and upper and lower air-blowing fans disposed in upper and lower outlet ports, respectively, wherein air sucked through the inlet port and the heat exchanger is directed to the fans, there are further provided input producing means for outputting a condition required for the outlet air from the outlet ports and phenomenon information on the outlet air, upper and lower fan operation mode determining means for determining the operation modes depending on the output signals from the input producing means, upper and lower fan operation mode control means for controlling the operation of both fans at the operation mode according to the commands from the operation mode determining means, and control means for optimizing the outlet air to a user.

Abstract: The air conditioner comprises a manual or automatic sensible temperature detection decision means consisting of a temperature detector for detecting room temperature, a hot/cold selector switch, a radiant heat detector, an air current detector and an outdoor temperature detector, an analog/digital signal converter, a microcomputer, a compressor and a blower, which is characterized in that temperature can be set to a thermal sense of a user, room temperature is automatically regulated step by step to coincide with the set temperature, or a sensible temperature is set automatically by the temperature detection and setting function and thus kept constant at all times.

Abstract: An air flow control device for an air conditioner includes a compressor, an outdoor side heat exchanger, expansion means and a room side heat exchanger in sequence, wherein the improvement comprises a room side unit with a upper and lower outlet ports, having the room side heat exchanger therein, upper and lower air-blowing fans disposed in the room side unit so as to face the upper and lower outlet ports, respectively, controller for controlling the operations of the air-blowing fans, a covering member positioned at least one of the outlet ports so as to open and close the corresponding outlet port, and a driving device for controlling the opening and closing operations of the covering member.

Abstract: An air conditioning method with use of an air conditioner comprises a step of determining whether or not an input signal is produced from a plurality of switches for providing conditions, a step of determining an established temperature on the basis of the signal from the switches, a step of comparing data provided by the established temperature determining step with the room temperature detected by the temperature detector to produce a signal, and a step of controlling the compressor based on the signal as a result of the comparison.

Abstract: In a hot air type heating apparatus having two air outlet ports, a temperature of air current blown out of an auxiliary outlet port provided on an outlet port for a high temperature air is rendered to be at a slightly warm temperature level, thereby realizing an improved hot air type heating apparatus capable of distributing warm air to every corner of a large room to effect uniform room warming, and of removing uncomfortableness to a dweller near the heating apparatus owing to a temperature difference caused by the two air currents blown out of the two outlet ports.

Abstract: A warm-air heating apparatus has a warm-air blowing port 2 for blowing warm air which is warmed in a heat source 4 provided in a casing after having been sucked through an air intake port 3, and a non-warm-air blowing port 9 provided independent of the warm-air blowing port 2 in which a blower 5 or 11 is placed for each port 2 or 9 to feed warm air to the lower part of a room and to feed non-warm air to the upper part of the room respectively so as to wrap the warm air with the non-warm air whereby temperature distribution in the vertical direction in the room is improved. The warm-air heating apparatus keeps living space warm to create a comfortable heating condition for the room and reduces wasted energy having been consumed to warm the ceiling area of the room in the conventional apparatus thereby improve efficiency of the heating apparatus.
