摘要： An air conditioner 1 of the embodiment of the present invention, when all compressors 21a - 21c have been stopping for a given time or more, starts an air conditioning operation 5 without performing pressure equalizing control in switch units 6a - 6d with starting the operation of the air conditioner 1. Also, when the stopping time of all compressors 21a - 21c is less than the given time, the air conditioner 1 performs the pressure equalizing control by controlling switch units 6a - 6d with starting the operation of the air conditioner 1. In this case, when the stopping time reaches the given time during execution of the pressure equalizing processing 10 control, the pressure equalizing processing control being executed is stopped and the air conditioning operation is started.

摘要： A CPU 110 compares the extracted outside air temperature with a first low pressure saturation temperature. When the outside air temperature is lower than the first low pressure saturation temperature, the CPU 110 switches a first three-way valve 22 and a second three-way valve 23 so that a second outdoor heat exchanger 25 is used as a condenser and that a first outdoor heat exchanger 24 is not used. When the outside air temperature is higher than a second low pressure saturation temperature which is the first low pressure saturation temperature to which a predetermined temperature is added, the CPU 110 switches the first three-way valve 22 and the second three-way valve 23 so that the first outdoor heat exchanger 24 is used as a condenser and that the second outdoor heat exchanger 25 is not used.

摘要： When the temperatures of outdoor heat exchangers 23a and 23b detected by outdoor heat exchanger temperature sensors 57a and 57b become equal to or higher than 5 degrees C and the sucking superheating degrees of compressors 21a and 21b become equal to or lower 5 than 0 degrees C while an air conditioning apparatus 1 is performing the reverse defrosting operation, the reverse defrosting operation is stopped and the heating dominant operation is resumed. At this time, the total operating times of the compressors 21a and 21b are reset. The sucking superheating degrees of the compressors 21a and 21b are obtained by subtracting the low pressure saturation temperatures calculated from the sucking pressures of 10 the compressors 21a and 21b, from the temperatures of the refrigerants sucked into the compressors 21a and 21b which temperatures are detected by the sucking temperature sensors 54a and 54b. 33a 56a 23a 43a 55a 40a 30a 30b 30 8a8a1 8 2a 4, a / al 2a3 a -- n_'7 2a b 32 72 a 53a- 7 018a 86a 83a 3 8A d . 3g 5 a 5 2 6 a ?- 6 1 a 21 a 58a57 Ig 327- , 36a- 51 a -1 - Ta 54a 25a 34a 32b- 318b8 8b 88b 33b 56b 23b 43b 55b 8b) 2b- 31 bb f224b_ 84b M86b 83b 53b- ---- 6b A61bt Ehb 58b5 36b 51 b 8c862b 8c7 2c 81 c 88c 54b 25b 34b 84c 86c 83c VIEW 110a, b2c 120a, b 1 MEMORY 8a-d _j Tc 130a, b 87d 62c COMNCAT10ON INDOOR UNIT 8d) 82d8d 88d 84 6d 86d 9d . 9d _j Tdl 6$d

摘要： An air conditioning apparatus 1 includes first start control and second start control as its start control. In the first start control, first outdoor heat exchangers 24a, 24b are controlled to function as evaporators and second outdoor heat exchangers 25a, 25b are controlled to function as condensers. Thus, even when the compressors 21 a, 21 b are driven on at a given rotation number, the discharge pressures thereof can be prevented from increasing, thereby being able to prevent the internal pressures of the compressors 21 a, 21 b from increasing. Also, after end of the first start control, the first outdoor heat exchangers 24a, 24b and second outdoor heat exchangers 25a, 25b are all controlled to function as evaporators, and the compressors 21a, 21b are driven on at a given rotation number. This can shorten the rising time of the heating capacity in the start of the normal heating operation.
