Abstract: PURPOSE:To simplify a connecting work to shorten a working period, and to save a space by connecting the power supply device and load resistor unit of an air conditioner to a transmission line only by turning-on the connection switch of one air conditioner at the time of connecting plural air conditioners to the transmission line. CONSTITUTION:This equipment is equipped with a power supply device 7 which supplies direct currents to a pair of transmission lines 1, a load resistor unit 8 in which a resistor 9 and a capacitor 10 are serially connected and a connection switch 11 which simultaneously connect both the power supply device 7 and the load resistor unit 8 to the transmission lines 1 in parallel with each other. At the time of setting an air conditioner 2 and connecting it to the transmission lines 1, when the connection switch 11 is turned on, the power supply device 7 and the load resistor unit 8 are automatically connected to the transmission lines 1. Therefore, the connecting work of the power supply device 7 and the load resistance unit 8 to the transmission lines 1 and the setting space of the power supply device 7 and the load resistor unit 8 are unnecessitated because the connection switch 11 of one of the plural air conditioner has only to be thrown at the time of connecting plural air conditioners to the lines 1.

Abstract: PROBLEM TO BE SOLVED: To aim at suppression of phenomena that condensated water or the like of a compressor and a system adheres to the surface of a flat heater body and enhances water holding ability, and hydrolysis and deterioration are caused when vaporized by heating, and thermal expansion of a silicone rubber insulator constituting the flat heater body is generated by heating while the insulator softens, and that the insulation deterioration is derived by generation of cracks due to these repetitions. SOLUTION: This flat heater body generates heat being mounted on a compressor of an air conditioner and supplied with power, and retains the warmth of a compressor. The heater body part of flat heater body 1, the silicone rubber insulator 2 having a heater part, and the silicone rubber insulator 3 at whose surface laver of the side contacting to a compressor metal powders are compounded are simultaneously extrusion-molded, and by enhancing the heat transfer of the flat heater body, an effect to suppress the deterioration of the silicone rubber insulator of the flat heater body is obtained.

Abstract: PURPOSE:To enable control even by a single air conditioner or by plural air conditioners by deciding a control code corresponding to each switch of a switch group to be operated by an operator and transmitting an address code showing the air conditioner to execute the control. CONSTITUTION:A control code generating means 12 generates the control code corresponding to each switch of a switch group 11. A control code decision type address code generating means 14 decides the control code and generates the address code corresponding to an address set by an address setting means 13 in the case of the control code to the single air conditioner. In the case of the control code to the plural air conditioners, the address code is generated to control the plural air conditioners. Next, a transmission code generating means 15 transmits the above mentioned control code and address code as infrared transmission signals. Therefore, the single air conditioner can be controlled and even the plural air conditioners can be controlled as well.

Abstract: PROBLEM TO BE SOLVED: To eliminate the fault that a crank case heater is energized in a short time after the stop of a compressor and therefore the amount of power consumption is large, in a technique of suppressing the stagnation of a refrigerant in the compressor at the stop thereof. SOLUTION: The air conditioner comprises a discharge temperature sensor 4, the crank case heater 8, the compressor 10, and a heat storage material 11 provided on the outer peripheral surface of the compressor 10. The energy of heating in the operation of the compressor is stored in the heat storage material. As a result, the lowering of the temperature of a compressor oil reservoir can be reduced and the stagnation of the refrigerant can be suppressed.
