Cooling system with individual feed flow to multiple evaporator zones

摘要

The cooling system 10 comprises (a) a liquid-tight circulation loop 11 comprising a compressor 12, a condenser 14 and an evaporator 18, the evaporator 18 having at least three evaporator zones, each evaporation The vessel zone has an inlet bore 36 which measures the state of the refrigerant in the evaporator 18 with a refrigerant condition sensor 44 located upstream of the evaporator outlet bore 34 and the refrigerant to the evaporator 18 A liquid-tight circulation loop further configured to control the flow of the refrigerant in the evaporator 18 based on the measured state of the refrigerant in the evaporator 18; and (b) And a controller 40 for controlling based on the measurement state of the refrigerant upstream of the evaporator exit hole 34.(FIG.
