Problems solved by technology

[0004] In order to solve the above technical problems, a gas-liquid separator is provided, which is applied to the heat pump system. The flow regulating device of the gas-liquid separator can adjust the opening of the liquid return channel section according to the level of the oil liquid in the tank, thereby adjusting the liquid return. speed, the invention solves the problem that the existing gas-liquid separator accumulates refrigerant and oil, which causes the performance of the refrigeration system to decline due to lack of refrigerant, and also avoids the blockage of the return channel and the failure of the normal return of liquid, and the compressor due to lack of The problem of oil failure or even burning

Abstract

The invention relates to the technical field of heat pump systems, and discloses a gas-liquid separator and a heat pump system. The gas-liquid separator adjusts the sectional area of a liquid return channel through a ball float valve to adjust the liquid return speed. The gas-liquid separator is used for solving the problems that a liquid return hole of an existing gas-liquid separator is easily blocked, refrigerants with higher liquid level are easy to accumulate in the gas-liquid separator, and the liquid return speed of a lubricating oil mixture cannot be adjusted. Due to the fact that the flow sectional area of return liquid is adjustable, it can be guaranteed that under various working conditions of the heat pump system, lubricating oil separated out of the gas-liquid separator can return to a compressor quickly, the refrigerants separated from the gas-liquid separator can quickly return to a refrigerating system, liquid impact does not happen to the liquid return amount, and therefore normal operation of the compressor is guaranteed.

Description

technical field [0001] The invention relates to the technical field of heat pump systems, and discloses a gas-liquid separator and a heat pump system. Background technique [0002] At present, heat pump systems are widely used in household appliances and other fields. In existing water heaters and air-conditioning systems that use heat pump systems, a gas-liquid separator is generally installed between the compressor and heat exchanger of the heat pump system to improve the heat pump system. of normal operation. [0003] In the design of the gas-liquid separator of the existing air conditioner and heat pump, such as figure 1 As shown, after the gaseous refrigerant containing oil (lubricating oil, liquid refrigerant mixture) enters the tank from the inlet pipe, the gas and liquid are separated, and the gas returns to the compressor from the outlet pipe, and the separated lubricating oil and refrigerant The liquid is deposited at the bottom of the tank, and when the liquid l...
