Kind Code:
B2
Abstract:
PURPOSE:To recover the retained refrigerant reliably without effect by start and stop of a compressor by furnishing a first timer that integrates the operating period of time of a compressor for every indoor unit till a first set time, and a second timer that opens an on-off valve for a second set period of time. CONSTITUTION:In case a compressor is in operation and an indoor unit 2a is OFF, a CPU 6a of an outdoor unit 1 transmits an on-off valve 'close' instruc tion to the indoor unit 2a until a timer 14a finishes to count time. And when it reaches the set time set by the timer 14a, the outdoor unit 1 sets a timer 15 and transmits an on-off valve 'open' instruction to the indoor unit 2a. This instruction is continuously transmitted to the indoor unit 2a while the timer 15 counts time, and recovery of the retained refrigerant is carried out. After that, when it reaches the second set time set by the timer 15, timer 14a and timer 15 are reset, and the on-off valve 'close' instruction is transmitted from the outdoor unit 1 to indoor unit 2a.
