Net is filtered the particulate matter in air.
The operation principle of the utility model is as follows：
Cooling in summer dehumidification process：
(1) heat pump：Compressor 3 compresses C mouth of the refrigerant through four-way valve 7 and is condensed into the second condenser 8, using
First expansion valve 9 throttles, and converges into heat exchanger 12 with the refrigerant come out from the first condenser 6 and freezes, most afterwards through four-way valve
E, compressor 3 is returned to for S mouthfuls；
(2) new wind turbine：Fresh air pre-cooled device 4 precooling dehumidifying, dehumidifies using evaporator 5, and 5 effect on moisture extraction of evaporator is by the
The aperture of two expansion valves 10 determines that being heated to setting temperature using the first condenser 6 send to room, and wind pushing temperature is swollen by third
The aperture of swollen valve 11 determines.
Winter heating's humidification：
(1) heat pump：7 energization of four-way valve acts, and piston moves to the right under the effect of the pressure, and D is communicated with E, compressor 3
It compresses E mouth of the refrigerant through four-way valve 7 and condenses heat release into heat exchanger 12, heat cold water, saved with from the second expansion valve 10
Refrigerant interflow after stream, throttles using the first expansion valve 9, absorbs heat into the second condenser 8, then is saved with third expansion valve 11
Stream heat absorption refrigerant interflow, most afterwards through four-way valve 7C, S mouthfuls return to compressor 3；
(2) new wind turbine：The pre-cooled device 4 of fresh air preheats, and is further heated using evaporator 5,5 heating temperature of evaporator
It is determined by the aperture of the second expansion valve 10, if the excessively high third expansion valve 11 of opening of 5 heating temperature of evaporator carries out drop appropriate
The amplitude of temperature, cooling is determined that this measure is that priority layer is relatively low by the aperture of third expansion valve 11；
Transition season：
It can be adjusted according to the second expansion valve of parameter pair 10 of user setting and the aperture of third expansion valve 11, such as load
It is smaller, it can directly close chilled(cooling) water return (CWR) and be heated or freezed using refrigerant, reduce the loss of indirect heat exchange.
In conclusion the heat pump of the utility model shares a compressor with Fresh air handling units, unit COP is improved, there is section
About environmental protection, floor space it is small, reduce Fresh air handling units noise the advantages that.
