Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2015218954
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigeration cycle device capable of effectively ensuring overcooling degree and overheat degree, and suppressing deterioration of heating performance and liquid back to a compressor.SOLUTION: A compressor 4, flow passage switching means 5, a condenser 6, a throttle mechanism 8 and an evaporator 9 are sequentially connected by a refrigerant pipeline, and a refrigerant circuit where refrigerant is circulated is provided. The refrigerant circuit includes an internal heat exchanger 7 performing heat exchange between refrigerant heading for the throttle mechanism 8 from the condenser 6 and refrigerant heading for the compressor 4 from the evaporator 9 with counterflow. The internal heat exchanger 7 has a double pipe structure comprising an inner pipe and an outer pipe. The inner pipe is connected between the condenser 6 and the throttle mechanism 8. The outer pipe is connected between the evaporator 9 and the compressor 4.
