Title:
TWO-PHASE FLOW AIR CONDITIONING SYSTEM WITH FREE COOLING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2022/160339
Kind Code:
A1
Abstract:
A two-phase flow air conditioning system with a free cooling function, the system comprising at least one compressor (1), a condenser (2), a throttling device (3), a low-pressure circulation drum (4), a refrigerant circulation pump (7), at least one direct-expansion flow regulation device (8), at least one direct expansion-type evaporator (9), and a plurality of control valves (5, 6, 10, 15) used for switching operating conditions. The air conditioning system realizes full-liquid operation of the evaporator by means of the pressurization of a liquid pump, and improves the use efficiency of the evaporator. In addition, when the outdoor ambient temperature is low, the operation of the compressor is stopped, and free cooling is realized by means of valve switching, thereby further reducing energy consumption for cooling, and improving the utilization rate of social resources.
