Abstract

The invention discloses a refrigerant pump for a refrigerant pump and compressor double-circulation system. The refrigerant pump comprises a pump shell and a pump core body, wherein the pump core bodyis fixedly connected with the pump shell; and one end of the pump core body is provided with a pump inlet, the pump core body is connected with an outlet pipe A which communicates with the pump inletand is used for outputting a high-pressure refrigerant medium to the outside of the pump shell when the pump core body works, and a flowing channel for conveying the refrigerant medium is arranged atthe position, between the pump inlet and the outlet pipe A, in the pump core body. According to the refrigerant pump for the refrigerant pump and compressor double-circulation system, the refrigerantmedium is directly introduced into the pump shell, a liquid storage tank and a complex pipeline connected between the pump and the liquid storage tank do not need to be arranged, so that the double-circulation system is more efficient and smaller in occupied area; the pump inlet has no pipeline resistance loss from the liquid storage tank to the pump inlet section in the past, so that the pump isnot prone to cavitation, the pump is more reliable, the adaptability is wider, and the system is more reliable and stabler; and the refrigerant medium passes through the flowing channel so that a certain effect of lubricating and cooling internal parts of the pump core body can be exerted.

Description

technical field [0001] The invention relates to a refrigerant pump, in particular to a refrigerant pump used in a dual circulation system of a refrigerant pump and a compressor. Background technique [0002] Refrigerants, also known as refrigerants, refrigerants, and refrigerants, are medium substances used to complete energy conversion in various heat engines. These substances typically increase power with a reversible phase change, such as a gas-to-liquid phase change. Such as steam in a steam engine, refrigerant in a refrigerator, etc. [0003] The refrigerant pump and compressor dual circulation system is a refrigeration system with the functions of refrigerant pump circulation and compressor circulation. In the refrigerant pump refrigeration cycle, when the outdoor temperature is lower than the indoor temperature, the refrigerant releases heat in the outdoor condenser and condenses into a liquid state, then is pumped to the indoor evaporator, absorbs indoor heat, and ...
