Heat recovery air-conditioning water heater with descaling function

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...

[0002] At present, the widely used air conditioner discharges a large amount of heat to the outside when it is running in cooling mode; the air energy heat pump water heater discharges a large amount of cold to the outside when it is running. This energy is not used, resulting in a great waste of energy

[0003] Traditional air source heat pump water heaters basically heat tap water directly. This is the most direct and ideal heating method. Although the heat loss is small and the heating efficiency is high, there is also the stubborn problem that the scaling of the heating tube is difficult to remove.

Moreover, the water tank has not been treated with anti-disturbance. When using hot water, cold water is poured into the water tank from the bottom. Due to the impact of tap water pressure, the hot and cold water is disturbed, resulting in the phenomenon of intermittent cold and hot when using hot water.
