HEAT PUMP SYSTEM HAVING HEAT EXCHANGER

摘要

A heat exchanger of a heat pump system is provided to prevent the overload of a compressor in a heating mode by raising the temperature of refrigerant through heat exchange between refrigerant of low temperature with the hot air of the compressor. A cap(100) is formed on a peripheral surface of a compressor(10) for collecting hot air generated fro the compressor. A heat exchange pipe(60) is connected to an indoor heat exchanger at an end and an expansion valve(40) at the other end for heating refrigerant flowing through the heat exchange pipe.
