Between a kind of dual system row, air conditioning system comprises multiple-working mode, and concrete operating principle is as follows:
1)Single refrigeration mode
As shown in Figure 3, when cold passage internal temperature is more than air conditioning system setting temperature, air conditioning system between row between setting row During normal work, i.e. single refrigeration mode, the first compressor 1 starts, and low temperature out is low by the first vaporizer 3 for the first compressor 1 The refrigerant gas of pressure are compressed into the refrigerant gas of High Temperature High Pressure, are formed often through entering the first condenser 13 and carrying out condensing heat release The refrigerant liquid of warm high pressure, by the forced convertion of outdoor fan 14 by heat dissipation in outdoor air environment, room temperature is high The refrigerant liquid of pressure enters through first throttle device 2 through the refrigerant liquid of the condensed normal temperature high voltage of the first condenser 13 Form the refrigerant liquid of low-temp low-pressure after row reducing pressure by regulating flow, enter and be evaporated heat absorption in the first vaporizer 3 to be changed into low temperature low Enter the suction end of compressor after the refrigerant gas of pressure, carry out sending cold wind by the first blower fan 6.
2)Heat pattern again
As shown in Figure 4, when when between row, air conditioning system needs reheating(When between row, the cryogenic temperature of air-conditioning is relatively low, but humidity Larger, need to reduce further humidity), in order to reach the purpose of constant temperature and humidity, enter reheat mode, the first compressor 1 opens Dynamic, by the first vaporizer 3, the refrigerant gas of low-temp low-pressure out are compressed into the refrigerant gas of High Temperature High Pressure to compressor 1, Carry out condensing the refrigerant liquid that heat release forms normal temperature high voltage through entering the first condenser 13, by the pressure of outdoor fan 14 By heat dissipation in outdoor air environment, the refrigerant liquid of normal temperature high voltage is condensed normal through the first condenser 13 for convection current The refrigerant liquid of warm high pressure forms the refrigerant liquid of low-temp low-pressure after first throttle device 2 carries out reducing pressure by regulating flow, enters The suction end of compressor is entered, by the after the refrigerant gas entering that being evaporated in the first vaporizer 3 absorbs heat and being changed into low-temp low-pressure One blower fan 6 carries out sending cold wind;
Meanwhile, the second compressor 12 is started, the refrigerant gas of the High Temperature High Pressure of the second compressor 12 aerofluxuss pass through four Logical reversal valve 13(Now four-way change-over valve 1 does not go up electricity)Port B, port D enter first heat exchanger 4(Now the first heat is handed over Parallel operation is operated as condenser)Carry out condensing the refrigerant gas that heat release forms normal temperature high voltage, then through the second throttling dress Put 9 carry out reducing pressure by regulating flow after become the refrigerant gas of low-temp low-pressure, enter second heat exchanger 10(Now second heat exchanger It is operated as vaporizer)In be evaporated absorbing heat after form the refrigerant gas of low-temp low-pressure and be back to the air-breathing of compressor End, described second heat exchanger 10 carries out blowing a cold wind over by the second blower fan 11 and absorbs the hot-air heat outside air-conditioning between row, fall Air-conditioning ambient temperature between low row, between row, air conditioning system carries out reheating.When system does not need reheating, the second compressor 12 closings.
3)Double refrigeration modes
As shown in Figure 5, when between row, air conditioning system needs to increase refrigerating capacity, can enter double refrigeration modes with control system,
First compressor 1 starts, and by the first vaporizer 3, the refrigerant gas of low-temp low-pressure out are compressed into compressor 1 The refrigerant gas of High Temperature High Pressure, carry out condensing the refrigerant liquid that heat release forms normal temperature high voltage through entering the first condenser 13, By the forced convertion of outdoor fan 14 by heat dissipation in outdoor air environment, the refrigerant liquid of normal temperature high voltage passes through The refrigerant liquid of the condensed normal temperature high voltage of the first condenser 13 forms low after first throttle device 2 carries out reducing pressure by regulating flow The refrigerant liquid of warm low pressure, entering being evaporated absorbing heat in the first vaporizer 3 be changed into the refrigerant gas of low-temp low-pressure after enter The suction end of compressor, carries out sending cold wind by the first blower fan 6;
Meanwhile, the second compressor 12 is started, the refrigerant gas of the High Temperature High Pressure of the second compressor 12 aerofluxuss pass through four Logical reversal valve 13(Now electricity on four-way change-over valve 1)Port B, port C enter second heat exchanger 10(Now the second heat exchange Device is operated as condenser)Carry out condensing the refrigerant gas that heat release forms normal temperature high voltage, then through second throttling device 9 Become the refrigerant gas of low-temp low-pressure after carrying out reducing pressure by regulating flow, enter first heat exchanger 4(Now first heat exchanger conduct Vaporizer is operated)In be evaporated absorbing heat after form the refrigerant gas of low-temp low-pressure and be back to the suction end of compressor, Described first heat exchanger 4 is blown a cold wind over by the first blower fan 6, and described second heat exchanger 10 is carried out by the second blower fan 11 Blowing hot-air.
4)Air-conditioning fault mode between row(Auxiliary cooling)
When row between air-conditioning fault, as shown in Figure 6, as extremely idle in the first compressor in the case of, by second compression Machine 12 starts, and the refrigerant gas of the High Temperature High Pressure of the second compressor 12 aerofluxuss pass through four-way change-over valve 13(Now four-way commutation Electricity on valve 1)Port B, port C enter second heat exchanger 10(Now second heat exchanger is operated as condenser)Enter Row condensation heat release forms the refrigerant gas of normal temperature high voltage, then becomes low temperature after second throttling device 9 carries out reducing pressure by regulating flow The refrigerant gas of low pressure, enter first heat exchanger 4(Now first heat exchanger is operated as vaporizer)In carry out The refrigerant gas forming low-temp low-pressure after evaporation endothermic are back to the suction end of compressor, and described first heat exchanger 4 is passed through First blower fan 6 is blown a cold wind over, and described second heat exchanger 10 carries out blowing hot-air by the second blower fan 11.
It should be noted that the first compressor can also be arranged at outside, it is arranged at same casing with the first condenser Interior.
The foregoing is only preferred embodiment of the present utility model, all according to this utility model claim done equal Deng change and modification, covering scope of the present utility model all should be belonged to.
