Abstract
PURPOSE: To prevent the steep lowering of the heating capacity in an air conditioner provided with several outdoor heat exchangers by giving high pressure refrigerant selectively to these outdoor heat exchangers frosted from a compressor for defrosting.
CONSTITUTION: When the first and the second outdoor heat exchanger 5 and 6 are frosted, electromagnetic switch valves 10 and 11 are selectively opened, and high pressure refrigerant is selectively given to these outdoor heat exchangers 5 and 6 by operations of three-way valves 7 and 8 from a compressor 1 to operate these heat exchangers 5 and 6 as condensers for defrosting. Consequently, the whole system is not necessarily switched over to the cooling operation for defrosting, preventing the steep lowering of the heating capacity.
