Air conditioner
Document Type and Number:
Japanese Patent JP6006664
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an air conditioner capable of ensuring small internal heat loss in a channel switching mechanism.SOLUTION: An air conditioner comprises a refrigerant circuit in which a compressor, a channel switching mechanism, an indoor heat exchanger, an expansion valve, and an outdoor heat exchanger are connected by a high-pressure-side connection pipe and a low-pressure-side connection pipe. The channel switching mechanism includes: a first channel switching mechanism that connects the compressor to the indoor heat exchanger during a heating operation; and a second channel switching mechanism that connects the outdoor heat exchanger to the compressor during the heating operation. The first channel switching mechanism and the second channel switching mechanism each include a valve body switching a channel of the refrigerant circuit, and the high-pressure-side connection pipe is connected to the second channel switching mechanism above the valve body of the second channel switching mechanism.
