the A port of the outdoor three-way valve 11 is connected with the water inlet end of the outdoor water heat exchanger 14, and the water outlet end of the outdoor water heat exchanger 14 is communicated with the water tank 9; the port B of the outdoor three-way valve 11 is communicated with the water tank 9;
and a temperature and humidity sensor 15 is further arranged in the room, and a temperature sensor 16 and an electric control system 17 are arranged in the water tank 9 and are electrically connected.
The evaporator 1, the humidifier 2 and the indoor water heat exchanger 3 are installed indoors in a stacked manner, and an indoor heat radiation fan 18 is arranged on any one side of the evaporator.
The humidifier 2 is an ultrasonic atomizer humidifier 2.
The water tank 9 is filled with fluid heat exchange medium.
The fluid heat exchange medium is clear water.
The working principle is as follows: when heat pump set dehumidifies for the thermostatic chamber, the evaporimeter refrigeration, utilizes the condensation to vapor when the evaporimeter is refrigerated to reduce the humidity in the air, wherein, because during the evaporimeter refrigeration, will certainly lead to indoor temperature to reduce, consequently, during the refrigeration, require indoor water heat exchanger 3 to heat, in order to offset the temperature reduction when refrigerating, thereby realize that the dehumidification in the thermostatic chamber does not lower the temperature. Under this mode of operation, the water pump work, with the high-efficient jar of pump income pipeline normal water pump, utilize water to trade the heat that produces when heat pump set refrigerates, at this moment, indoor two-way solenoid valve 19 is opened, and outdoor two-way solenoid valve 10 closes, and the water after being heated directly gets into indoor water heat exchanger 3, heats indoor water heat exchanger 3 to for indoor heating, thereby realize the thermal cycle.
When the heat pump unit refrigerates for the thermostatic chamber, the evaporator refrigerates, and heat exchange is carried out between air in the thermostatic chamber and the evaporator so as to reduce the indoor temperature, and the high-efficiency tank needs to take away heat generated during refrigeration of the evaporator through water circulation. At the moment, the water pump works, the water pump pumps the water in the water bucket into the high-efficiency tank for heat exchange, the indoor two-way electromagnetic valve 19 is closed, the outdoor two-way electromagnetic valve 10 is opened, the O-B port of the outdoor three-way valve 11 is communicated, the water after heat exchange enters the water bucket, heat exchange is carried out between the water in the water bucket and the high-efficiency tank by utilizing water circulation in the water bucket, and heat generated during refrigeration is stored in the water bucket. When the water temperature in the water barrel rises to the upper limit, the O-A of the outdoor three-way valve 11 is conducted, and the outdoor water heat exchanger 14 exchanges heat with air to continuously realize refrigeration and heat dissipation of the heat pump unit.
When the heat pump unit is used for heating the thermostatic chamber, the heat pump unit does not need to start the compressor when the water temperature of the water barrel is higher than a set value, only the water pump needs to be started, the outdoor two-way electromagnetic valve 10 is closed, the indoor two-way electromagnetic valve 19 is opened, hot water sucked by the water pump enters the indoor water heat exchanger 3 through the indoor two-way electromagnetic valve 19, and the thermostatic chamber is heated after the indoor water heat exchanger 3 is heated by the hot water. Meanwhile, the return water of the indoor water heat exchanger 3 is circulated back to the water bucket through the first return water electromagnetic valve 12 under the condition that the second return water electromagnetic valve 13 is closed and the first return water electromagnetic valve 12 is opened. When the water temperature in the water bucket is lower than a certain value and is not enough to heat, the compressor is started by the heat pump unit, the four-way valve works reversely, the evaporator is utilized to heat, the high-efficiency tank is in a heat absorption state, the indoor two-way electromagnetic valve 19 is closed, the outdoor two-way electromagnetic valve 10 is opened, and the O-B port of the outdoor three-way valve 11 is communicated, so that the water in the water bucket continues to enter the high-efficiency tank for heat exchange. When the water temperature in the water barrel is lower than A limit value, the O-A port of the outdoor three-way valve 11 is communicated, and the outdoor water heat exchanger 14 exchanges heat with air to continuously realize heating and heat absorption of the heat pump unit.
Compared with the prior art, the system in the present case is at normal atmospheric temperature, can store the cask with the waste heat that heat pump set refrigeration produced when or take out the wet in, when heat pump set heats, the preference carries out the heat transfer with retaining, when the heat accumulation is not enough, can carry out the heat transfer with the air, utilize heat pump set and water heat transfer high, with the relatively lower characteristic of air heat exchange efficiency, with heat cycle use, when satisfying its operation requirement, reduce the energy consumption loss, improve the thermal efficiency, so can extensively use widely.
