AIR-CONDITIONER CAPABLE OF IMPROVING THE HEAT EXCHANGE EFFICIENCY OF AN INNER HEAT EXCHANGER

摘要

PURPOSE: An air-conditioner is provided to prevent damage to the internal components of a compressor by employing an inner heat exchanger capable of evaporating liquid refrigerant before injecting gas refrigerant to the compressor.;CONSTITUTION: An air-conditioner comprises a main refrigerant circuit(100), first and second refrigerant injection paths, and an inner heat exchanger(50). The inner heat exchanger implements selective heat exchange between refrigerants flowing through the first and second refrigerant injection paths and the main refrigerant circuit according to the activation of the first and second refrigerant injection paths. The inner heat exchanger comprises a main heat exchange tube constituting a part of the main refrigerant circuit and first and second refrigerant heat exchange tubes(110,120) constituting a part of the first and second refrigerant injection paths.;COPYRIGHT KIPO 2012
