Gas-liquid separator and heat exchange equipment

Abstract

The invention discloses a gas-liquid separator and heat exchange equipment. The gas-liquid separator comprises a shell, a gas-liquid separating structure and a heat exchange structure, wherein the shell comprises an accommodating cavity, a first through hole, a second through hole and a third through hole which are formed in a spaced manner are formed in the side wall of the accommodating cavity;the gas-liquid separating structure is used for separating a gaseous refrigerant and lubricating oil, the outlet of the gas-liquid separating structure communicates to the accommodating cavity, the air inlet of a compressor communicates to the accommodating cavity through the third through hole, and the inlet of the gas-liquid separating structure communicates to the outlet of a first heat exchanger; and the heat exchange structure is arranged in the accommodating cavity and comprises a heat exchange inlet and a heat exchange outlet, the heat exchange inlet communicates to the outlet of a second heat exchanger through the first through hole, and the heat exchange outlet communicates to the inlet of the first heat exchanger through the second through hole. The gas-liquid separator integrates the heat exchange structure and the gas-liquid separating structure, so that the space of a unit is saved.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a gas-liquid separator and heat exchange equipment. Background technique [0002] Under the national policy of energy conservation and emission reduction, in order to improve the competitiveness of products in the market, more and more manufacturers pay attention to the development of heat pump systems with large refrigeration capacity and high energy efficiency ratio. At present, in order to increase the capacity and energy efficiency ratio of the unit, the manufacturer needs to add a heat exchanger (also called an economizer) to the system to increase the subcooling degree and increase the temperature of the gas refrigerant. [0003] However, after adding a heat exchanger to a traditional heat pump system, the heat exchanger needs to occupy the cavity of the unit, which affects the installation of other components of the unit or the size of the unit is large, wh...

Problems solved by technology

[0004] Based on this, after adding a heat exchanger to the traditional heat pump system, because the heat exchanger needs to occupy the unit cavity, which affects the installation of other components of the unit or the size of the unit is large, it is not conducive to the installation and promotion of the heat pump system. A gas-liquid separator and heat exchange equipment. The gas-liquid separator integrates a heat exchange structure and a gas-liquid separation structure, which saves the space of the unit and enables the gas-liquid separator to simultaneously store gaseous refrigerant and lubricating oil. The function of separating and increasing the degree of subcooling and superheating of the unit; the heat exchange equipment includes the above-mentioned gas-liquid separator, so the heat exchange equipment has the advantages of small size, high refrigeration efficiency and low risk of unit liquid entrainment
