Compressor connection is stated, the other end of the compressor is connected with that four-way valve, the first access and the wind of the four-way valve
One end of cool condenser connects, and the air-cooled condenser other end is connect with first check valve, and the of the four-way valve
Three-way is connect with one end of the water-cooled condenser, and the other end of the water-cooled condenser is connected in the third check valve,
First check valve and the third check valve are parallel with electric expansion valve, the electric expansion valve and the four-way valve
Alternate path is connect with the other end of the evaporator.
In above-mentioned dehumidifier, the evaporator is wind-cooled evaporator.
In above-mentioned dehumidifier, the wind-cooled evaporator is equipped with air intake vent.
In above-mentioned dehumidifier, the air-cooled condenser is equipped with air outlet.
In above-mentioned dehumidifier, the inflow temperature of the water-cooled condenser is 30 ° -40 °

A kind of dehumidifier that above-mentioned technical proposal is provided, compared with prior art, advantage includes：In four-way valve
Access on the case where check valve is set, changes the flow direction inside traditional four-way valve, refrigerant is avoided to flow back in four-way valve send out
It is raw；And by the way that air-cooled condenser is arranged on the first access of four-way valve, realize the drying to gas after evaporator cool-down dehumidification
And be discharged, and the refrigerant of air-cooled condenser flow to evaporator by the decompression processing of electric expansion valve and forms cycle with evaporator
Circuit；Since water-cooled condenser is arranged in third path, when temperature is too low, four-way valve electromagnetic valve coil power-off, iron core pushes away
Dynamic valve bowl movement, the first access is blocked, and third path is dredged, and the refrigerant of low-temperature condition flow to water-cooled condenser, high pressure
Refrigerant releases heat because of condensation, improves dehumidifier temperature, and flow to evaporator via the decompression of electric expansion valve processing, when
Dehumidifier temperature improve to a certain degree when, four-way valve is powered, and the first access is opened at this time, and third path is closed, and realizes normal
Dehumidifying, avoids the case where dehumidifier can not work normally due to temperature is too low.
