Air conditioner system and control method thereof

Abstract

The invention discloses an air conditioner system comprising a compressor, a four-way valve, a condenser, an expansion valve and an indoor unit. The air conditioner system further comprises a water pump, a subcooler and a water tank which is used for collecting low-temperature condensate water discharged by the indoor unit. The water pump is connected with the subcooler and the water tank and canconvey the low-temperature condensate water in the water tank to the subcooler. The subcooler is arranged between an outlet of the compressor and the four-way valve and cools a high-temperature refrigerant conveyed out by the compressor through the low-temperature condensate water. According to the air conditioner system, recycle of cooling capacity of the condensate water is achieved through thesubcooler, and cooling capacity, taken away by the condensate water, of the air conditioner system is reduced. Meanwhile, condensing temperature and pressure are lowered, waste work of the system is also reduced accordingly, and energy consumption of the air conditioner system is further reduced. The flow of the condensate water is controlled according to a subcooling effect, the condensate wateris utilized maximally, and insufficient utilization of the condensate water is avoided. The invention further discloses a control method of the air conditioner system.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to an air conditioning system. In addition, the present invention also relates to a control method of the above-mentioned air conditioning system. Background technique [0002] During the cooling process of the air-conditioning system, the indoor unit produces a large amount of condensed water with low temperature. The existing indoor unit condensed water treatment method is basically to drain it directly, resulting in a large amount of cooling capacity in the condensed water not being used reasonably. Usually, the temperature of the condensed water produced by the indoor unit is as low as 15°C, and the condensed water is continuously generated with the operation of the indoor unit, while the cooling medium that needs to be cooled by the air-conditioning system during the refrigeration process is as high as 75°C. If the low-temperature condensed water is directly discharged without ...

AI Technical Summary

Problems solved by technology

If the low-temperature condensed water is directly discharged without reasonable cooling capacity recovery, the hard-won cooling capacity will be wasted, resulting in a waste of energy
