Title:
空調装置
Document Type and Number:
Japanese Patent JP4232463
Kind Code:
B2
Abstract:
When a dehumidifying and heating operation is set in an air conditioner, refrigerant is circulated from a compressor to the compressor through a first exterior heat exchanger, a decompression device, an interior heat exchanger, an another decompression device, an inner heat exchanger and a second exterior heat exchanger, in this order. Further, by controlling a throttle opening degree of the another decompression device, a refrigerant temperature in the interior heat exchanger can be set higher than that in the second exterior heat exchanger. Thus, even when the interior heat exchanger is controlled to a temperature to be not frosted, heat can be absorbed from outside air in the second exterior heat exchanger. Accordingly, when an outside air temperature is low, by setting the dehumidifying and heating operation, air to be blown into a compartment can be dehumidified while sufficiently increasing heating capacity.
