Abstract
The utility model discloses a cold wall type heat pump hot water system of fluorine, including compressor, the cold wall of fluorine, choke valve, evaporimeter and water tank. The fluorine cold wall is welded on the outer wall of the water tank and separated from the water tank, and the condensing coil is inserted into a space formed by the fluorine cold wall and the water tank and is isolated and sealed from the fluorine cold wall and the water tank. The compressor system and the fluorine cold wall are respectively filled with the same or different working media, a high-temperature high-pressure refrigerant generated by the compressor heats the condensation tube bundle, and the condensation coil heats the working media in the fluorine cold wall, so that the working media generate uniform high temperature and heat water in the water tank. By adopting the structure, when the heat pump heats hot water, the heating area is increased, the temperature is uniform, and the starting speed is high; when the heating is stopped, the gaseous working medium in the fluorine cold wall has the advantages of large thermal resistance and good heat preservation effect. For a heat pump system adopting R290 as a working medium, the heat exchange between excessive refrigerants and the outer wall of the water tank is avoided, and the filling amount of the heat pump system is further greatly reduced.
