Its principle is: those skilled in the art know, for the refrigerant in compression-type refrigerating system, refrigerant
Pressure is higher, and temperature is also higher.
When air passes sequentially through first evaporator to N grades of evaporators by upstream toward downstream, gas flow temperature is gradually decreased.
Gas flow temperature highest at first evaporator, refrigerant pressure (i.e. evaporating pressure) in first evaporator also highest.N
Grade evaporator at gas flow temperature after multi-stage evaporator cools down its temperature it is minimum, the refrigerant pressure in N grades of evaporators
(i.e. evaporating pressure) is also minimum.
Similar reason, when air passes sequentially through first order condenser to N grades of condensers by upstream toward downstream, air-flow temperature
Degree gradually rises.Gas flow temperature at first order condenser is minimum, refrigerant pressure (the i.e. condensation pressure in first order condenser
Power) it is also minimum.Gas flow temperature at N grades of condensers its temperature highest after the heating of multi-stage condensing device, in N grades of condensers
