As described in the background art, the bathroom in the prior art is widely heated by adopting an energy-saving and environment-friendly heat pump water heater, and the heat pump water heater is mainly used for heating water through cooperation among an evaporator, a compressor, a condenser, a throttling device and a liquid storage tank. However, the heat pump water heater can only supply hot water, and the dehumidification and heating of the bathroom are usually realized by an exhaust fan and a lamp-heating type bathroom heater. The bathroom heater has certain regulation effect on the environmental temperature in the bathroom, but can not adjust the air humidity in the bathroom environment, and the traditional lamp warms up and cools down when the bathroom heater is in operation, influences the comfort level when the user bathes.

The utility model provides a circulating system with an environment adjusting function and a heat pump water heater, and solves the problem that different equipment is required to be installed for dehumidification, heating and hot water requirements in a bathroom in the prior art.

As shown in fig. 1, fig. 1 is a schematic structural diagram of a circulation system with environmental conditioning function according to the present utility model; comprising the following steps: a compressor 400, a condensate tank 500, and a circulation duct 100; the evaporator 200 and the condenser 300 are arranged in the circulating air duct 100, and air sucked by an air inlet of the circulating air duct 100 is blown out from an air outlet after passing through the evaporator 200 and the condenser 300 in sequence; the evaporator 200, the compressor 400, the condenser 300 and the condensate tank 500 are connected by pipes to form a refrigerant circuit 700, and the refrigerant in the evaporator 200 flows through the refrigerant circuit 700, through the compressor 400, and then flows through the condenser 300 and the condensate tank 500, respectively, and flows back to the evaporator 200.

According to the utility model, the evaporator 200 and the condenser 300 are sequentially arranged in the circulating air duct 100, so that the hot and humid air sucked by the air inlet of the circulating air duct 100 is dehumidified and heated and then blown out from the air outlet, and the heat in the sucked hot and humid air is also used for heating cold water of the condensing water tank. Not only can the hot water supply and demand be realized, but also the dehumidification and heating demands of the bathroom can be simultaneously solved. And the energy waste of the hot and humid air is reduced through the energy recovery of the hot and humid air.

In the above technical solution, it can be seen that the circulation system of the present embodiment has two circulation, namely, a refrigerant circulation and an air circulation.

The refrigerant circulates, and the low-temperature and low-pressure refrigerant in the evaporator 200 is compressed into a high-temperature and high-pressure liquid refrigerant after passing through the compressor 400, flows through the condensate water tank 500 and the condenser 300, heats the condensate water tank 500 and the condenser 300, and then turns into a low-temperature refrigerant to flow back to the evaporator 200, thus circulating, and completing the heating of hot water and the dehumidification of air.

After passing through the evaporator 200, the hot and humid air sucked by the air inlet exchanges heat with the refrigerant in the evaporator 200, specifically, the refrigerant in the evaporator 200 evaporates into a gaseous state in the evaporator 200, and absorbs a large amount of heat from the hot and humid air, and the water vapor in the hot and humid air is condensed and separated out from the evaporator 200 after being cooled, so that the aim of dehumidification is fulfilled.

When the dehumidified air flows through the high-temperature condenser 300 again, heat is absorbed from the condenser 300, the purpose of heating is achieved, and the dehumidified air is discharged from the air outlet.

In the above-described embodiments, both the condenser 300 and the evaporator 200 are fixed in the circulation duct 100 by bolts.

By way of example, the evaporator 200 can be in the shape of a tube sheet, a tube strip, and a stack.

The segment evaporator consists of copper or aluminum round tube or aluminum fins on a flat tube sleeve, and the aluminum fins are tightly contacted with the round tube through a tube expansion process. The structure is simple and the processing is convenient.

The tube-strip evaporator is formed by welding a porous flat tube and a snakelike heat dissipation aluminum strip, and the process is more complex than that of a tube sheet, and double-sided composite aluminum materials and porous flat tube materials are needed. The heat transfer efficiency of the evaporator can be improved by about 10% compared with the tube sheet type evaporator.

The laminated evaporator is formed by laminating two aluminum plates punched into a complex shape together to form a refrigerant channel, and a snake-shaped heat dissipation aluminum belt is clamped between every two channels. The evaporator also needs double-sided composite aluminum materials, and has high welding requirements, so that the processing difficulty is maximum, but the heat exchange efficiency is highest, and the structure is also the most compact.

For the three evaporators 200, because of different processing difficulties and different heat transfer efficiencies, the three evaporators 200 with different structures can be selected according to the operation requirements in practical application.

Illustratively, the evaporator 200 adopts an anti-corrosion heat exchanger, such as a titanium evaporator, which has super-hydrophilicity and is not easy to form a water bridge, so that air duct blockage can be avoided, and heat energy exchange efficiency is improved. And thus has better wear resistance and ultra-corrosion resistance, extending the useful life of the evaporator 200.

In the above technical solution, the liquid inlet of the evaporator 200 is further provided with an expansion valve, so that the liquid refrigerant with medium temperature and high pressure in the refrigerant circuit is throttled into low-temperature and low-pressure vapor, thereby improving the heat transfer efficiency of the refrigerant in the evaporator 200. The expansion valve may control the heat transfer efficiency of the evaporator 200 by controlling the valve flow.
