摘要： PROBLEM TO BE SOLVED: To approach a room temperature sensor to an indoor unit in the ceiling and ensure proper room temperature control corresponding to the position of such a room temperature sensor. SOLUTION: An air conditioning system air conditions each room A to D (i=1 to 4) with an indoor unit 1 disposed in the ceiling. There are provided outlets 4a to 4c and a suction inlet 5d in the neighbourhood of the ceiling on the side of the indoor unit 1 of the rooms A to C and the room D. There are provided room temperature sensors 6a to 6c and 7 in the vicinity of the outlets 4a to 4c and the suction inlet 5b. Room temperature (Ta)i detected by the room temperature sensors 6a to 6c of the rooms A to C is corrected in response to a temperature difference ((Ta)i-Tk) between the room temperature (Ta)i and suction air temperature Tk detected by a suction air temperature sensor of the indoor unit 1, and hence room temperature (Taf)i after the correction is estimated. Room temperature (Ta)4 detected by the room temperature sensor 7 of the room D is equally rendered to only minus correction. The indoor unit 1 performs room temperature control of the rooms A to D (i=1 to 4) based upon the room temperature (Taf)i after the correction.

摘要： PROBLEM TO BE SOLVED: To prevent water drops from dropping to the outside of a unit from a lead wire by fixing the lead wire at a lead wire fixing area provided on a drain guide which guides a water content deposited on the wall surface to a drain pan. SOLUTION: A site 55c of an earth wire 55 is fixed at the tip 54b provided in a drain guide 54 of an electric component box incorporated in a unit main body 1. When an air conditioner is operated in cooling mode, a heat exchanger 20 is subjected to condensation by the heat exchange with an air conditioned air and the water content drops into a drain pan 40. Condensation is produced on the earth wire 55 under the influence of the heat exchanger 20. The water drops which flow out from a wall surface 52b are collected at the site 55b of the earth wire 55 and drop into the drain pan 40 from the site 55c, which is located at the lowest position between one end 55a of the earth wire 55 and the site 55b in the upper part of the drain pan 40. Therefore, the whole water content generated around the electric component box 50 is housed in the drain pan 40, which prevents the leakage of the water content to the outside of the unit main body 1.

摘要： PROBLEM TO BE SOLVED: To prevent dew from adhering the outer surface of a ventilation duct by controlling the compression capacity of a capacity-variable compressor based on the detection data of a temperature sensor and a moisture sensor for detecting the temperature and moisture of air being sucked into an indoor machine and the duct outer surface temperature sensor of the ventilation duct. SOLUTION: A suction air temperature and moisture on cooling operation are detected and a zero-point-corresponding temperature Q corresponding to the data is read from a storage part (S102), a temperature Ta of a duct outer surface temperature sensor is detected (S103), and it is judged that a dew- formation prevention control is being made currently in the case of flag = 1 (S104). Otherwise, it is judged whether the temperature Ta is lower than the zero-point-corresponding temperature Q or not (S113). If it is lower, there is no risk of generating dew on the surface of the ventilation duct. Therefore, the flag is set to 1 (S114) for indicating that the dew formation prevention control is being made, an operating frequency Fn of a capacity-varying compressor is changed to a dew formation prevention frequency Fs (S115), and the speed of the capacity-varying compressor is reduced.

摘要： PURPOSE:To make it possible to obtain an optimum indoor set temperature and to realize comfortable air conditioning. CONSTITUTION:A correcting circuit 12 stores in its own memory corrective values which are determined respectively for a plurality of divided areas of an outdoor-air temperature so that the degree of comfort be zero, in such a manner that the values are divided into those for the time of a heating operation and those for the time of a cooling operation. When a detected value of an outdoor-air temperature To from an outdoor-air temperature sensor 14 is inputted, the correcting circuit 12 selects the corrective value DELTATo corresponding to the To and determines a set temperature Tsc after correction by adding up the DELTATo and a set temperature Ts obtained from a remote control. A frequency determining circuit 13 determines an inverter frequency (f) on the basis of a deviation (Ta-Tsc) of an indoor detected temperature Ta from the set temperature Tsc.

摘要： PURPOSE:To sense an outside air temperature without the needs for an outside air temperature sensor, require no consideration for a setting place and make the highly reliable detection of the outside air temperature possible without being adversely affected by sunshine and the like while lightening a working load at the time of installation and reducing cost. CONSTITUTION:A heat pump type freezing cycle is formed by connecting a capability variable compressor, a four-way valve, an outdoor heat exchanger, an expansion valve and an indoor heat exchanger to one another. Further, an inverter circuit 41 for supplying a drive electric power to the compressor 1 is provided, and an output frequency of the inverter circuit 41 is controlled according to an air conditioning load. An outdoor unit A has a heat exchanger temperature sensor 11 adapted to detect a temperature of the outdoor heat exchanger, and the temperature Te detected by the heat exchanger temperature sensor 11 at the time of starting operation is used as it is as an outside air temperature To during a predetermined period of time t1 from the start of operation. After a predetermined period of time t1 elapses from the start of operation, the temperature Te detected by the heat exchanger temperature sensor 11 is corrected in accordance with an output frequency of the inverter circuit to estimate the outside air temperature To.
