[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. First, open the first valve, the second valve and the third valve on the water inlet pipe. After the water supply tank, the water storage tank and the heating water tank are all filled with water, close the first valve, the second valve and the third valve. Open the third valve to circulate the liquid through the heating water tank, the water supply tank and the water storage tank. When the cold water passes through the heating water tank, it is heated to T3 of 55°C. At this time, open the third valve on the return pipe, and the water in the heating water tank is slowly pressed into the water supply tank by the water pressure. The liquid is transported to the water storage tank through the first connecting pipe on the water supply tank. The liquid in the first connecting pipe is connected to the second connecting pipe and the third connecting pipe, which plays a role of circulation and transportation until the water temperature T2 in the water supply tank reaches 55°C. This is completed. In this process, the variable frequency water pump requires a large flow rate, and the water flow rate is controlled by an electric proportional ball valve. First, circulate and heat the heating water tank, then guide the water, and then continue to heat and guide the water until the water supply tank T2 reaches 55°C and completes the heating.
[0014] 2. The heater can be turned on, and the heater conducts heat through the temperature conduction plate. In order to improve the uniformity of heating, the motor on the support frame can be turned on. The motor drives the temperature conduction plate to rotate through the heater. The temperature conduction plate can be connected through the shaft and the stirring rod to perform uniform stirring and heating to improve the uniformity of heating.
[0015] 3. The compressor operates normally, discharges high-temperature and high-pressure refrigerant vapor, which is reversed by the four-way reversing valve, flows through the shell-and-tube heat exchanger to produce hot water and becomes high-pressure medium-temperature liquid refrigerant. After being filtered in the treatment box, the electronic expansion valve throttles and reduces the pressure and flows through the treatment box again for filtration, enters the evaporator to evaporate and absorb heat to become low-pressure refrigerant vapor. The evaporator can pass through the first splicing pipe, pass through the four-way reversing valve, and then flow through the gas-liquid separator through the second splicing pipe, enter the compressor, and then be transported back to the shell-and-tube heat exchanger through the second delivery pipe on the four-way reversing valve, and the cycle continues.
[0016] 4. When filtering the liquid transported by the first delivery pipe, it can pass through the processing box and be filtered through the activated carbon plate and the filter screen plate in the processing box. In order to avoid the filter screen plate being blocked by filtered impurities, the electric motor can be turned on to drive the reciprocating screw to operate. When the reciprocating screw rotates, it can drive the moving block to move back and forth, and the moving block can drive the scraper to move smoothly. When the scraper moves, it can move smoothly with the support of the slider on the slide rod. When moving, the scraper can scrape off the impurities on the filter screen plate to avoid blocking the filter screen plate and moving the filtering circulation effect. When cleaning is needed, the sealing cover on the processing box can be removed, and the activated carbon plate and the filter screen plate on the sealing cover can be removed and taken out, and the impurities on the activated carbon plate and the filter screen plate can be cleaned and collected to improve the filtering effect.

Figure 1-10, the equipment can be supported and lifted by the workbench 1. First, open the first valve 4, the second valve 9, and the third valve 18 on the water inlet pipe 3. After the water supply tank 2, the water storage tank 6, and the heating water tank 10 are all filled with water, close the first valve 4, the second valve 9, and the third valve 18. Open the third valve 18 to circulate the liquid through the heating water tank 10, the water supply tank 2, and the water storage tank 6. When the cold water passes through the heating water tank 10, it is heated to T3 of 55°C. At this time, open the third valve 18 on the return pipe 17, and the water in the heating water tank 10 is slowly pressed into the water supply tank 2 by the water pressure. The liquid is transported to the water storage tank 6 through the first connecting pipe 5 on the water supply tank 2.

The evaporator 34 can pass through the first splicing tube 35 and the four-way reversing valve 36 to reverse, and then flow through the gas-liquid separator 38 through the second splicing tube 37 to enter the compressor 39, and then is transported back to the shell-and-tube heat exchanger 20 through the second delivery pipe 40 on the four-way reversing valve 36.
