AIR CONDITIONING UNIT, AND OPERATION CONTROL METHOD AND OPERATION CONTROL DEVICE FOR AIR CONDITIONING UNIT

摘要

The present disclosure relates to the technical field of air conditioners, and discloses an air conditioning unit, and an operation control method and an operation control device for an air conditioning unit. The air conditioning unit includes: a first refrigeration system including a first evaporator, a first compressor, a first condenser, a first one-way valve, and a first throttling element connected in sequence in a loop as well as a second one-way valve connected in parallel with the first compressor, and a first fluorine pump connected in parallel with the first one-way valve; and a second refrigeration system including a second evaporator, a second compressor, a second condenser, a third one-way valve, and a second throttling element connected in sequence in a loop as well as a fourth one-way valve connected in parallel with the second compressor, and a second fluorine pump connected in parallel with the third one-way valve, where the first evaporator and the second evaporator are arranged front and rear in sequence along a return air cooling duct. With the air conditioning unit, the energy consumption of the system can be reduced, the energy efficiency of the system can be improved, and a very uniform supply air temperature can be ensured, which is beneficial to more accurate control of the supply air temperature.
