[0026] The device 1 includes a condensate pipe 11, a condensate collection tray 12, a hot water preparation device 13, a refrigeration device 14, a condensate collection tray 15, and a water storage tank 16.

[0027] The refrigeration unit 14 includes a primary evaporator 141, a secondary evaporator 142, a condenser 143, an expansion valve 144, a liquid receiver 145, a refrigerant line 146, an absorber 147, and a diffuser 148. The diffuser 148 is fixedly connected to the top of the liquid receiver 145. The refrigerant line 146 is fixedly connected to the left side surface of the absorber 147 and installed at the bottom of the condenser 143. The expansion valve 144 is installed on the right side of the primary evaporator 141. Expansion valve 144 is installed on the left side of condenser 143. It seals the space between condenser 143 and expansion valve 144, allowing contents inside condenser 143 to enter the first-stage evaporator 141. Second-stage evaporator 142 is installed at the bottom of the first-stage evaporator 141 and inside condensate drip tray 15. First-stage evaporator 141 is installed inside condensate drip tray 12. Condenser 143 is installed in water storage tank 16. Internally, condensate from the primary evaporator 141, secondary evaporator 142, and condenser 143 flows into the water storage tank 16 via condensate drip tray 12 and condensate drip tray 15, enabling refrigeration. Condensate drip tray 12 is installed at the top of the condensate pipe 11, and condensate drip tray 15 is installed on the left side of the condensate pipe 11, with condensate drip tray 12 positioned above it. Condensate drip tray 12 is installed within the housing 3. At the top of the inner wall, condensate drip tray 2 15 is installed on the top of the inner wall of the housing 3. Condensate drip tray 1 12, condensate drip tray 2 15 and water storage tank 16 are installed on the inner wall surface of the housing 3. The condensate generated during the evaporation and heat absorption process in the primary evaporator 141 and the secondary evaporator 142 is collected through condensate drip tray 12 and condensate drip tray 2 15 and flows into the water storage tank 16 at the bottom of the condenser 143, where it exchanges heat with the ammonia refrigerant in the water storage tank 16 and absorbs heat.
[0028] The hot water preparation device 13 includes a generator 131, an electric two-way valve 132, a heat source 133, a hot water storage tank 134, an electric regulating valve 135, a ball valve 136, and a hot water pipeline 137. The electric regulating valve 135 is installed on the right side of the heat source 133, the ball valve 136 is installed on the right side of the hot water storage tank 134, the heat source 133 is installed on the right side of the hot water pipeline 137, and the hot water pipeline 137 is installed at the bottom of the tank 3. The tank 3 can determine the position of the hot water pipeline 137, thereby determining the position of the generator 131. At the same time, it can protect the safety of generator 131 and prevent damage to generator 131. Generator 131 is installed on the left side of hot water pipe 137. Refrigerant pipe 146 is installed inside generator 131 and on the right side surface of liquid storage tank 145. After ammonia water is heated in generator 131, ammonia gas evaporates and enters natural ventilation air-cooled condenser 143. After heat exchange with air in condenser 143, it is cooled and condensed. Electric two-way valve 132 is installed on the left side of hot water pipe 137.
[0029] When in use, the heat source 133 can collect heat to heat the tap water inside the hot water pipe 137, so that the heated tap water enters the generator 131, and the generator 131 can heat the ammonia water inside the refrigerant pipe 146.
[0030] The refrigerant line 146 is heated by the generator 131, which dilutes the ammonia solution. The ammonia evaporates and enters the condenser 143. The ammonia exchanges heat with the air in the condenser 143 and is then cooled and condensed. It then passes through the expansion valve into the first-stage evaporator 141 and the second-stage evaporator 142. In the first-stage evaporator 141 and the second-stage evaporator 142, the ammonia evaporates and absorbs heat, thus achieving the refrigeration function.
[0031] The condensate generated during the evaporation and heat absorption process in the primary evaporator 141 and the secondary evaporator 142 is collected through condensate collection pan 12 and condensate collection pan 15 and flows into the water storage tank 16 at the bottom of the condenser 143. It exchanges heat with the ammonia refrigerant in the condenser 143. After absorbing heat, the condensate evaporates directly, which cools the condenser 143 and avoids the problem of condensate pollution.
[0032] Ammonia gas in the first-stage evaporator 141 and the second-stage evaporator 142 enters the absorber 147 through pipes. At the same time, by means of the siphon principle, the liquid left in the liquid storage tank 145 and the refrigerant pipeline 146 enters the absorber 147, so that the ammonia gas and the liquid inside the absorber 147 can be mixed to form new ammonia water.
[0033] The generator 131 generates excess heat during the heating of the dilute ammonia solution. This heat is transferred to the water in the hot water storage tank 134 through heat exchange, heating it to the temperature required for domestic hot water, thus achieving the preparation of domestic hot water.
[0034] The steam or hot water inside generator 131 is at a high temperature, about 80°C. After heat exchange, the water temperature is also around 60°C. After entering the water tank, it can be used for domestic hot water.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
