A refrigerant 16 is arranged in 10, a pressure regulating seat 14 is arranged on the steam output pipe 11, a pressure regulating chamber is arranged inside the pressure regulating seat 14, the steam output pipe 11 is connected with the pressure regulating chamber, a pressure regulating piston 15 is arranged in the pressure regulating chamber, a guide sleeve 17 and a screw hole are arranged on the refrigeration casing 2 on the side of the pressure regulating seat 14, a slide rod 18 is arranged in the guide sleeve 17, the slide rod 18 is connected with the pressure regulating piston 15, an adjusting screw 19 is arranged in the screw hole, the adjusting screw 19 is rotatably connected with the pressure regulating piston 15, an adjusting hand wheel 20 is arranged on the end of the adjusting screw 19, a one-way valve 21 is arranged on the steam output pipe 11 and the condensation reflux pipe 12, a water inlet and a second connecting pipe 6 are arranged on the refrigeration casing 2 within the range of the condensation chamber 9, and the second connecting pipe 6 is connected to the thermal insulation water storage tank 3.

[0022] The air compressor 1 is an existing product. The air compressor 1 generates compressed air during operation, which is passed into the evaporation chamber 8 of the refrigeration housing 2 and then transported outward by the high-pressure air output pipe. Since the compressed air has a relatively high temperature, it exchanges heat with the refrigerant 16 in the evaporator 10 when it is in the evaporation chamber 8, and the steam of the refrigerant 16 enters the condensation tube 13 in the condensation chamber 9 through the steam output pipe 11, heats the water in the condensation chamber 9, and then transports it to the evaporator 10 through the condensation return pipe 12. The water in the condensation chamber 9 is heated by the condensation tube 13 and then transported to the heat-insulating water storage tank 3. In actual use, the position of the pressure regulating piston 15 in the pressure regulating chamber can be adjusted according to actual conditions, thereby changing the volume of the pressure regulating chamber, and finally changing the steam pressure in the pressure regulating chamber and the evaporator 10 to improve the heat exchange efficiency. The adjusting screw 19 cooperates with the screw hole to limit the position of the pressure regulating piston 15, and the sliding rod 18 cooperates with the guide sleeve 17 to make the pressure regulating piston 15 more stable during the adjustment process. It cooperates closely with the pressure regulating chamber and will not leak.

[0025] A water pump is provided on the second connecting pipe 6 for conveying water in the condensing chamber 9 of the refrigeration housing 2 to the heat preservation water storage tank 3. By conveying hot water to the heat preservation water storage tank 3 by the water pump, the flow rate of water can be effectively controlled to ensure sufficient heat exchange.

[0029] A fixed base 5 is arranged under the insulated water tank, and the fixed base 5 includes a protective ring 29. A fixed rectangular block 32 is protruding inwardly from the inner wall of the protective ring 29. Six support rods 30 are arranged at intervals at the lower part of the protective ring 29. A foot seat 31 is arranged at the bottom of the support rod 30. The insulated water tank is arranged on the fixed rectangular frame.
