Embodiment 1

[0033] The heat recovery air-conditioning water heater with descaling function provided in this embodiment can realize multiple operation modes such as hot water heating, heat recovery heating water heating in cooling air-conditioning mode, and heating air-conditioning, and can generate hot water above 50°C. Its structure is as Figure 1 to Figure 6 As shown, it is composed of a heat pump water heater and a heating and cooling air conditioner, wherein: the outdoor unit part and the heat exchange water tank 2 form a heat pump water heater, and the outdoor unit part and the indoor unit part form a heating and cooling air conditioner.

[0034] The heat exchange water tank 2 is provided with a water spray head 28, a freely retractable double helical tube 3 and a water injection slow flow device 22 from top to bottom inside; a drainage electric valve installed on the sewage pipe is provided at its lower part 30. The water inlet electric valve 23 installed on the water inlet pipe, t...

Embodiment 2

[0044] The heat exchange water tank 2 can also form a hot water circulation system that can store more hot water through the water outlet valve 26, the circulating water pump 35, the heat preservation water storage tank 34, and the circulating return water valve 29. The top water outlet pipe of the heat exchange water tank 2 is connected with the top of the heat preservation water storage tank 34, and the circulation water pump 35 is housed on this pipeline. Its bottom of the heat-insulating water storage tank 34 links to each other with the circulating water return valve 29 of the heat-exchanging water tank 2 through pipelines, forming a hot water circulation loop, and the water in the heat-insulating water storage tank 34 can be heated.

[0045] Described heat exchange water tank 2 can be equipped with auxiliary water tank, household can not be equipped with auxiliary water tank, and just is equipped with auxiliary water tank during commercial use. The auxiliary water tank i...

Embodiment 3

[0048] The heat exchange water tank 2 can also form a hot water circulation system through a water outlet valve 26 , a circulating water pump 35 , a hot water valve 33 , and a circulating return water valve 29 . The water outlet pipe of the heat exchange water tank 2 is equipped with a circulating water pump 35, and the water outlet pipe extends to each water point, and then returns to the circulating water return valve 29 of the heat exchange water tank 2, and forms a hot water circulation loop through the non-stop operation of the circulating water pump. Several hot water valves 33 can also be installed on the pipeline of its hot water circulation circuit, hot water is sent to each water point, can emit the hot water of constant temperature at any time.

Abstract

The invention relates to a heat recovery air-conditioning water heater with a descaling function. The heat recovery air-conditioning water heater is composed of a heat pump water heater and an air conditioner, wherein an outdoor unit part and a heat exchange water tank (2) form the heat pump water heater, and the outdoor unit part and an indoor unit part form the air conditioner. A sprinkler head (28), a double spiral pipe (3) and a water injection slow flow device (22) are arranged inside the heat exchange water tank (2) from top to bottom. An inlet pipe head and an outlet pipe head of the double spiral pipe (3) extend out of the heat exchange water tank and are connected to an outdoor unit, and the other ends of both the inlet pipe head and the outlet pipe head of the double spiral pipe (3) are arranged inside the heat exchange water tank (2) and are not fixed. According to the heat recovery air-conditioning water heater, various running modes such as heat recovery water heating and heating air-conditioning can be achieved during a water heating and refrigeration air-conditioning mode, and hot water of over 50 DEG C can be generated. After the heat recovery air-conditioning water heater runs for a period of time, a scale layer on the surface of the double spiral pipe (3) can be removed automatically in a physical method.

Description

technical field [0001] The invention relates to a heat recovery air-conditioning water heater device with descaling function, in particular to a cold and heat recovery heat pump water heater with descaling function and anti-disturbance function of a heat exchange water tank. Background technique [0002] At present, the widely used air conditioners discharge a large amount of heat to the outside when they are running in cooling mode; the air-energy heat pump water heaters discharge a large amount of cold to the outside during operation. These energy are not used, resulting in great energy waste. [0003] Traditional air source heat pump water heaters basically directly heat tap water. This is the most direct and ideal heating method. Although the heat loss is small and the heating efficiency is high, it also has the stubborn problem that the scaling of the heating tube is not easy to remove. Moreover, the water tank is not treated with anti-disturbance. When hot water is use...
