Title:
Heat pump cycle
Document Type and Number:
Japanese Patent JP6183223
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress degradation in heating capacity as compared with a conventional technique for a heat pump cycle configuring a gas injection cycle.SOLUTION: In an integrated valve 14 including valve elements 15 and 18 opening/closing a gas-liquid refrigerant passage 142b extending from a gas-liquid separation space 141b to a first refrigerant outlet port 142a and a liquid-phase refrigerant passage 141d1 extending from the gas-liquid separation space 141b to a second refrigerant outlet port 141e and stored in a body 140, a liquid-phase refrigerant passage 141d2 is formed in the body 140 for discharging liquid-phase refrigerant separated in the gas-liquid separation space 141b from a third refrigerant outlet port 141i when the valve element 15 closes the liquid-phase refrigerant passage 141d1 leading to the second refrigerant outlet port 141e. Furthermore, a fixed throttle 17 is provided in a pipe component 61 connected to an outside of the body 140 and constituting a refrigerant passage from the third refrigerant outlet port 141i to a refrigerant inlet of an outdoor heat exchanger 20.
