Title:
COMPRESSOR LIQUID SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/088043
Kind Code:
A1
Abstract:
The compressor liquid supply system, comprising: a first liquid taking pipeline (21), having one end communicated with a liquid supply port of an evaporator (13) for taking a liquid refrigerant from the evaporator (13); a second liquid taking pipeline (22), having one end communicated with a liquid supply portion of a condenser (12) for taking a liquid refrigerant from the condenser (12); a liquid supply pipeline (23), the other end of the first liquid taking pipeline (21) and the other end of the second liquid taking pipeline (22) being both communicated with one end of the liquid supply pipeline (23), and the other end of the liquid supply pipeline (23) being communicated with the inlet of a compressor (11); a pressurizing device (25) provided on the liquid supply pipeline (23) for regulating the pressure of the refrigerant in the liquid supply pipeline (23); and a parallel pipeline (24), both ends of which are communicated with the liquid supply pipeline (23) and are connected in parallel to the pressurizing device (25). The compressor liquid supply system reduces the use of a gear pump by providing the parallel pipeline (24), and reduces the energy consumption of the compressor.
