The hot water heat exchanger is connected with the outdoor unit through a fluorine path inlet and outlet pipe. The upper water outlet of the tank is connected with the radiation radiator, and the upper water outlet of the energy storage tank is lower than the bottom edge of the radiation radiator; an exhaust valve is arranged on the top of the radiation radiator, and the water outlet of the radiation radiator is connected with the energy storage connected to the water inlet of the tank.

The water outlet at the upper part of the energy storage tank is at least 200mm lower than the bottom edge of the radiation radiator.

The upper water outlet of the energy storage tank is also connected to at least one hot water terminal.

A valve is arranged on the communication pipeline between the water outlet on the upper part of the energy storage tank and the radiation radiator.

The water outlet of the above-mentioned radiant radiator and the water inlet of the energy storage tank are all communicated with the tap water inlet pipe.

A sewage pipe is arranged at the water inlet of the energy storage tank.

The above-mentioned outdoor unit includes an air-cooled evaporator, a compressor and a throttling mechanism connected with the air-cooled evaporator.

The utility model adopting the above-mentioned technical solution, on the basis of the existing fluorine tube through-the-wall heat pump water heater, uses the principle of natural circulation to connect the energy storage tank and the radiant radiator to form a natural circulation loop to provide heating for the auxiliary room. The utility model is suitable for users who need continuous or intermittent heating in toilets or other auxiliary small rooms. It can supply sanitary hot water and heating at the same time at a low cost. Its power consumption can save about 70% compared with ordinary electric water heaters or heating machines. It has energy saving , Practical, safe and reliable, easy installation and maintenance and other advantages, has a large potential market demand. In addition, the utility model is connected with a hot water terminal, which can provide bath water and/or several hot water for washing hands and vegetables.

Description of drawings

Accompanying drawing is the overall structure figure of the utility model.

Detailed ways

As shown in the figure, the utility model is made of outdoor unit 1 and indoor unit 2. The outdoor unit 1 includes an air-cooled evaporator 4 , a compressor 3 and a throttling mechanism 5 connected to the air-cooled evaporator 4 . An energy storage tank 7 and a hot water heat exchanger 6 located in the energy storage tank 7 are installed in the indoor unit 2, and the hot water heat exchanger 6 is connected to the compressor 3 and the throttling mechanism 5 in the outdoor unit 1 through the fluorine inlet and outlet pipes. In which, the hot water heat exchanger 6 is located in the middle and lower part of the energy storage tank 7, and its fluorine inlet and outlet pipes need to pass through the outer wall of the building.

In order to realize heating, in the utility model, the upper water outlet of the energy storage tank 7 is connected with the radiation radiator 10, and the upper water outlet of the energy storage tank 7 is at least 200 mm lower than the bottom edge of the radiation radiator 10. During construction, The energy storage tank 7 is installed on the floor, and the bottom of the radiation radiator 10 is 500mm higher than the top of the energy storage tank 7 . Then, an exhaust valve 9 is arranged on the top of the radiation radiator 10 , and the water outlet of the radiation radiator 10 is connected with the water inlet of the energy storage tank 7 .

A valve 8 is arranged on the communication pipeline between the water outlet on the upper part of the energy storage tank 7 and the radiation radiator 10, so as to facilitate intermittent heating for users.
