Abstract: PROBLEM TO BE SOLVED: To reduce waiting power without shortening the time elapsed until starting power supply very much, even when the outdoor air temperature is low. SOLUTION: A system comprising a compressor 1, a crankcase heater 2, a microcomputer 3, a program memory 4a, a delivery temperature sensor 5, and an outdoor air temperature sensor 6 is provided with means for supplying power to the crankcase heater, when the difference between the delivery temperature of the compressor and the outdoor air temperature becomes equal to or lower than a specified value during stoppage of the compressor. Since the stat of power supply can be determined depending on the outdoor air temperature, the time elapsed until the start of power supply does not become very short, even when the outdoor air temperature is low and so that waiting power can be reduced, while prolonging the lifetime of the crankcase heater.

Abstract: PROBLEM TO BE SOLVED: To provide an air conditioner capable of preventing dewing in an indoor machine without deteriorating a cooling capacity. SOLUTION: When a wet-bulb temperature value obtained by operating values detected by an indoor temperature sensor 11 and an indoor humidity sensor 12 through an indoor wet-bulb temperature operating device, the value of an indoor heat exchanger capacity obtained by operating a value detected by an outdoor air temperature sensor 17 through an outdoor heat exchanger operating device, and the value of air volume of the indoor machine are coincident; volume operating device M4 commands the increase of air volume to an air volume control device M3 to prevent the dewing in the indoor machine. Thereafter, when the wet-bulb temperature value, the outdoor heat exchanger capacity value and the air volume value of the indoor machine are deviated from a condition, the air volume operating device M4 commands to the air volume control device M3 to return to the initial set air volume, whereby the dewing in the indoor machine can be prevented without deteriorating the cooling capacity and the abolition of water absorbing members or the reduction of insulating materials in the indoor machine can be contrived.

Abstract: PROBLEM TO BE SOLVED: To provide an air conditioner capable of removing bacteria in a heat exchanger as a main air channel of the conditioner and a bacteria breeding place and a drain pan and supplying a clean air into a room. SOLUTION: The air conditioner comprises a heat exchanger a3 contained in a housing of an indoor unit, a drain pan M5, a drain pump M6 for draining the drain stored in the pan M5, and an ozone water supply unit M150 for supplying an ozone water to the exchanger a3 and the pan M5. The ozone water is supplied from the unit M150 to the exchanger a3 and the pan M5 at an arbitrarily predetermined time during operating of the indoor unit to remove bacteria in the exchanger a3 as the main air channel of the conditioner and the bacteria breeding place and the pan M5 and to supply the clean air to the room.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of choking and defective operation of a motordriven expansion valve. SOLUTION: This air-conditioner comprises a compressor 11; an outdoor heat-exchanger 12; a motor-drive expansion valve 13; an indoor heat-exchanger 14; and a control device 17 to repeat opening and closing operation of the motor- driven expansion valve 13 the given number of times before the compressor 11 is stopped during completion of operation. This constitution eliminates a need to provide a flow equalizing circuit to specify a flow down direction of a refrigerant to a one-way and prevents choking of the motor-driven expansion valve due to adhesion of sludge despite of refrigerant circuit constitution similar to a general air-conditioner, i.e., constitution of a refrigerant circuit consisting of a compressor, an outdoor heat-exchanger, a motor-driven expansion valve, and an indoor heat-exchanger.

Abstract: PURPOSE:To provide a communication device for an air conditioner in which a connection work can be simplified, a working period can be shortened and a space saving can be attained by a method wherein a connection work of an electrical power supplying device to a transmitting line is eliminated and an installing space for the electrical power supplying device is not required. CONSTITUTION:A communication device for an air conditioner 2 is comprised of an electrical power supplying device 7 for supplying DC current to a transmitting line 1; a non-electrical power supplying signal generating means 9 for generating a non-electrical power supplying signal when no electrical power is supplied to the transmitting line 1; and a latch signal generating means 13 for generating a latch signal when an input voltage is more than a predetermined voltage. Further, this communication device is comprised of a latch circuit 14 for latching the non-electrical power supplying signal when the latch signal is inputted; a connection signal generating means 15 for generating a connection signal when both the non-electrical power supplying signal and the latch signal are inputted; and a switching circuit 16 for connecting the electrical power supplying device 7 to the transmitting line 1 when the connecting signal is inputted.

Abstract: PURPOSE:To eliminate unnecessary consumption of energy by providing an indoor side heat exchanger temperature detector and a compressor timer, detecting that a variable windage unit is fully closed during room cooling operation by the fact that the exchanger temperature attains a predetermined value or lower before the operating time of a compressor becomes a predetermined value, and controlling the compressor and an indoor side blower. CONSTITUTION:A compressor timer 30 is started during room cooling operation, and integration of operating time of a compressor 6 is started. Temperature X deg.C of an indoor side heat exchanger 3 is detected by an indoor side heat exchanger temperature detector 29, compared with a predetermined temperature T1, the timer 30 ends integration of predetermined time if (X = T3) is detected, and the compressor 6 is returned to the control of normal operation time. If the timer count is not completed, it is compared with a predetermined temperature T2 lower than the T1, the compressor 6 is stopped if (X
