Title: AIR CONDITIONING DEVICE
Abstract:
The purpose of the present invention is to increase superheating of low pressure refrigerant by using heat from operating electric parts without impairing piping layout and maintenance by way of a simple and inexpensive configuration. This air conditioning device (1) comprises a compressor that compresses refrigerant, a reactor (15) that is an electric part that generates heat when operating and that constitutes a controller electric circuit to drive the compressor, and a low pressure refrigerant pipe (25) that supplies the refrigerant to the compressor. The low pressure refrigerant pipe (25) has a heat exchanger section (25c) in which an intermediate portion of the low pressure refrigerant pipe branches into a plurality of (two, for example) round pipe branch pipes (25b) and then converges back into one pipe. The plurality of branch pipes (25b) are disposed near the reactor (15) so as to be able to exchange heat.
