Gas heat pump system with rapid oil filling function

Abstract

The invention discloses a gas heat pump system with a rapid oil filling function. The gas heat pump system comprises a refrigerant circulation system and a compressor lubrication oil rapid-filling system, wherein the refrigerant circulation system comprises a compressor, an oil separator, a gas-liquid separator, an outdoor heat exchange system, a four-way valve, an electronic expansion valve, a liquid storage device, an indoor heat exchanger, a one-way valve I, a one-way valve II, a one-way valve III and a one-way valve IV; the compressor lubrication oil rapid-filling system comprises an oil separator, an oil return pipe, at least one lubrication oil filling port and an oil return electromagnetic valve. The gas heat pump system disclosed by the invention is simple and stable in structure,and the smooth filling of compressor lubrication oil can be ensured; the compressor lubrication oil filling efficiency can be improved and the time can be saved; and the safe and rapid filling of thecompressor lubrication oil can be achieved no matter whether the gas heat pump system is stopped or works, and then the adverse effect on the gas heat pump system can be prevented.

Description

technical field [0001] The invention relates to a gas heat pump system, in particular to a fast oil-filling gas heat pump system, which can quickly fill a compressor lubricating oil during the working process of a gas heat pump unit. Background technique [0002] During the production and processing of air-conditioning and refrigeration equipment, a certain amount of compressor lubricating oil needs to be filled. The filling of compressor lubricating oil in conventional air-conditioning and refrigeration equipment systems is relatively simple, because the compressor is basically not subject to lubricating oil. Impact. However, if the gas heat pump air conditioning system uses the traditional method to fill the compressor lubricating oil, it will affect the production efficiency. [0003] In addition, the compressor oil chamber of the gas heat pump unit has less oil storage. In order to meet the normal operation of the gas heat pump unit, the compressor lubricating oil must ...

However, if the gas heat pump air conditioning system uses the traditional method to fill the compressor lubricating oil, it will affect the production efficiency

[0003] In addition, the compressor oil chamber of the gas heat pump unit has less oil storage. In order to meet the normal operation of the gas heat pump unit, the compressor lubricating oil must be replenished in time. However, when the gas heat pump unit is working, the compressor lubricating oil cannot be directly filled.
