Abstract

The invention discloses a siphon type gas-liquid separator used for a heat pump, comprising a barrel made of a seamless steal tube, a closing end disposed at the upper portion thereor, a gas return bushing disposed in the internal portion of the barrel center, a vertical gaseous refrigerant gas return tube connected at the upper portion of the gas return bushing, a gas feeding bushing welded in the tangential direction of the barrel, a gas feeding tube connected with the gas feeding bushing, a base welded at the bottom of the barrel, and a low level oil return tube and a high level oil return tube both welded on the internal wall of the gas return bushing. The terminals of both the low level oil return tube and the high level oil return tube extend outside the lower opening of the internal wall. The inventive gas-liquid separator can not only prevent compressor liquid hammer, but also let the lubricant oil carried by the refrigerant enter the compressor to depress gas discharge temperature of the compressor, increase service life of the compressor, and enhance reliability of the system and ability for refrigeration and heating.

Description

technical field [0001] The invention relates to a gas-liquid separator for a heat pump system, in particular to a gas-liquid separator for a heat pump which adopts a siphon way to return oil. Background technique [0002] Currently, existing heat pump systems include a compressor, a four-way valve, a condenser, an expansion valve, and an evaporator. In the refrigeration process, the gaseous refrigerant pressurized by the compressor enters the air-side heat exchanger through the four-way valve to exchange heat, then cools down, and then depressurizes through the expansion valve to become a low-temperature and low-pressure liquid, and then enters the water-side heat exchanger to evaporate Then it becomes a low-pressure gas and is sucked into the compressor through the four-way valve. During the heating process, the gaseous refrigerant pressurized by the compressor enters the water-side heat exchanger through the four-way valve to release heat and then cools down, so that the ...
