Description

Technical Field

[0001] The utility model relates to the technical field of chiller equipment, in particular to an oil-gas separation cylinder of a chiller unit. Background Art

[0002] Currently, in chillers, the evaporator pressure is relatively low, and lubricant oil recovery typically requires high-pressure injection. High-pressure gas or liquid is introduced into the ejector, flowing rapidly through the ejector cavity to create a low pressure. The pressure differential then ejects the lubricant oil from the evaporator back into the oil tank, completing the evaporator oil recovery process. Due to the low evaporator pressure and correspondingly low saturation temperature, the recovered lubricant oil is often mixed with a high concentration of low-temperature, low-pressure refrigerant liquid. Fuel tank temperatures are relatively high (typically 55°C to 65°C). Directly injecting lubricant oil mixed with liquid refrigerant back into the tank will cause the refrigerant to evaporate, absorbing heat from the lubricant and causing significant oil temperature fluctuations. Therefore, to minimize the impact of oil recovery on oil temperature, it is often necessary to separate the liquid refrigerant from the lubricant before returning it to the tank.

[0003] The existing oil-gas separation cylinder of the chiller has low separation efficiency for refrigerant and oil droplets. The refrigerant loses a lot of energy during the flow process, the pressure drop is too large, and the compressor cannot obtain sufficient oil droplets. Therefore, the utility model proposes a chiller oil-gas separation cylinder to solve the above problems. Utility Model Content
