Title:
AIR CONDITIONING SYSTEM WITH EMERGENCY REFRIGERATION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2020/177195
Kind Code:
A1
Abstract:
Disclosed is an air conditioning system with emergency refrigeration function, comprising an evaporation heat transfer unit (1), a condensation heat transfer unit (4) used for cooling the refrigerant, an emergency refrigeration heat transfer unit (3) used for providing auxiliary cold source to cool the refrigerant, and a refrigerant supercharging unit (2) used for transporting the cooled refrigerant to the evaporation heat transfer unit (1). The evaporation heat transfer unit (1) comprises an evaporator (1-2) and a first fan (1-1); a refrigerant outlet of the evaporator (1-2) is connected with a refrigerant inlet of the condensation heat transfer unit (4) and a refrigerant inlet of the emergency refrigeration heat transfer unit (3); a refrigerant outlet of the condensation heat transfer unit (4) and a refrigerant outlet of the emergency refrigeration heat transfer unit (3) are respectively connected with a refrigerant inlet of the refrigerant supercharging unit (2); and a refrigerant outlet of the refrigerant supercharging unit (2) is connected with a refrigerant inlet of the evaporator (1-2). Added an emergency refrigeration heat transfer unit, the air conditioning system has the emergency refrigeration function, thereby preventing partial high temperature in the machine room when the air conditioning system halts for a short time and avoiding damage to machine room devices.
