Related introduction

The air energy heat pump uses the heat in the air to generate heat energy, which can provide different hot water and cold and warm requirements for the whole family with large water volume, high water pressure and constant temperature 24 hours a day, and at the same time complete the above requirements with the least energy consumption.

With the development of economy, people's requirements for quality of life are getting higher and higher. People's requirements for bathing are getting higher and higher. Gas water heaters, electric water heaters and solar water heaters are far from meeting people's needs for comfort, energy saving and safety.

In developed countries in Europe and America, the ratio of cold water to hot water is 1:9 (China is 9: 1). In Europe and America, cold water is only used for drinking, flushing toilets and washing cars, while hot water is used for other purposes. Domestic central water heaters have a market share of over 90% in Europe and America (less than 3% in China).

The working principle of air energy heat pump is "inverse Carnot" and inverse Carnot cycle. Through the operation of the compressor system, the heat in the air is absorbed to make hot water. The specific process is: the compressor compresses the refrigerant, the compressed refrigerant with increased temperature passes through the condenser in the water tank to make hot water, and the heat-exchanged refrigerant returns to the compressor for the next cycle.

In this process, the air heat is absorbed by the evaporator and introduced into the refrigerant, which is introduced into the water to generate hot water. Air-energy heat pump water heater is a new generation of water heater heated by compressor air. Figuratively speaking, it is the "outdoor machine" that compresses the air like a water pump to raise the air temperature, and then conducts the heat to the indoor water storage tank through a liquid that will boil at-17℃, and then releases the heat to the water.
