Document Type and Number:
Japanese Patent JP2017044435
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an air conditioner having a gas-liquid separator capable of improving an air conditioning efficiency and improving reliability in operation of the air conditioner by preventing a liquid-back phenomenon.SOLUTION: This invention comprises: a temperature sensor 51 for measuring a temperature of refrigerant at a downstream side of a flow rate adjustment part 8 of a bypass pipe 9; a temperature sensor 52 for measuring a temperature of refrigerant near a connecting part with a bypass pipe 9 at a main pipe 10 connected to a compressor 11 and a location in front of merging of both pipes 9, 10; and a control part 50 to control an adjustment of flow rate of gas refrigerant at the flow rate adjustment part 8 on the basis of a detected temperature of the temperature sensor 51 and a detected temperature of the temperature sensor 52. The control part 50 performs the controlling operation in such a manner that a difference between the detected temperature of the temperature sensor 51 and the detected temperature of the temperature sensor 52 is kept between an optimal upper limit temperature difference and an optimal lower limit temperature difference lower than the optimal upper limit temperature difference.SELECTED DRAWING: Figure 1
