Description

Technical Field

[0001] The present invention relates to the field of oil separators, and specifically to an integrated oil separator. Background Art

[0002] An oil separator is a key component in a compression refrigeration cycle, used to separate the lubricating oil carried in the compressor exhaust, preventing excessive lubricating oil from entering the evaporator / condenser and causing a decrease in heat exchange efficiency. Its oil outlet pipe needs to stably return the separated lubricating oil to the compressor crankcase or oil collector, and at the same time, it needs to meet functional requirements such as dynamic oil return control, oil circuit safety guarantee, and impurity filtration.

[0003] The existing oil separator oil outlet and gas outlet usually adopt a single flange or threaded interface. To meet the above functional requirements, multiple sets of parallel or serial pipelines and accessories need to be externally connected. These components are connected through pipe fittings such as tees and elbows. More than 3 sets of independent pipes need to be arranged around the oil outlet of a single oil separator, and it is very easy to interfere with components such as the condenser fan and the electrical control cabinet in a compact unit.

[0004] There is a significant contradiction between the functional implementation and space efficiency of the existing multi-pipeline external connection design of oil separators. It is urgent to break through the existing architecture through flow channel integration, topological optimization, or intelligent valve technology to meet the upgrade requirements of high-density and high-reliability refrigeration systems.
