30 to cold accumulating pond cold-storage.The second airborne refrigeration system 30 shown in Fig. 1 uses vaporization cycle system
Cooling system, when its start work time, gaseous coolant by compressor 31 compress after temperature and
Pressure raises, and then in condenser 32, cooling becomes liquid, then swollen after reducing temperature
Swollen valve 33 expands reduction pressure and becomes gaseous state and liquid mixing refrigerating medium, by cold accumulating pond 11
Second heat exchanger 13 becomes gaseous state, enters back into compressor 31 compression circulation.Second airborne system
Cooling system 30 duty, by motor compressor control, is released heat in condenser 32 and passes
Pass ram-air, the second heat exchanger 13 absorbs heat, it is achieved cold-storage.Second machine
Carry refrigeration system 30 and can take discontinuous operation side according to the performance of the first airborne refrigeration system 20
Formula, it is ensured that cold accumulating pond 11 cold storage capacity ensures super large thermal power equipment functional reliability.
Cold accumulating pond releases cold work process:
Cold accumulating pond 11 realizes the cooling of super large thermal power equipment by releasing cold loop.In super large heat
During power apparatus work, the cold loop of releasing shown in Fig. 1 starts work prior to super large thermal power equipment
Making, refrigerating medium refrigerating medium is under the second pump 44 drives, after filter 45 impurity screening
Enter cold accumulating pond the 3rd heat exchanger 14 to carry out being divided into multichannel for the excess of imports after heat exchange reduces temperature
The big airborne heat-producing device of thermal power 42, converges into a road, enters after absorbing the heat that its work distributes
Enter pump circulation, i.e. achieve cold accumulating pond 11 and release the cold and airborne heat-producing device of super large thermal power 42
Cooling.
