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 hot water passes sequentially through first order condenser to N grades of condensers by upstream toward downstream, water temperature by
Edge up height.Water flow temperature at first order condenser is minimum, the refrigerant pressure (i.e. condensing pressure) in first order condenser
It is minimum.Water flow temperature at N grades of condensers its temperature highest after the heating of multi-stage condensing device, the system in N grades of condensers
Refrigerant pressure (i.e. condensing pressure) also highest.
Therefore, first evaporator and N grades of condensers belong to same heat pump system, it will be able to make highest evaporating pressure
It is corresponding with highest condensing pressure；Similarly, N grades of evaporators and first order condenser belong to same heat pump system, it will be able to
Keep minimum evaporating pressure corresponding with minimum condensing pressure.Similarly, N-1 grades of evaporators and second level condenser belong to together
One heat pump system, it will be able to keep secondary low evaporating pressure corresponding with secondary low condensing pressure.In this way, ensuring that multiple compressions
(compressor inlet connects evaporator, inlet pressure reactive evaporation pressure to the inlet and outlet of machine；Compressor outlet connects condenser, out
Mouthful pressure is condensing pressure) refrigerant pressure difference it is average, reduce the energy consumption of heat pump system on the whole.
