System Design

Air source heat pump water heater is a device that moves heat from the air around to heat water, then satisfy the user's daily demand for hot water. Its working principle is based on the Reverse Carnot Cycle principle. Usually, a heat pump water heater has four main components: evaporator, compressor, condenser and expansion device. The refrigerant is the medium to connect the four parts. Just using a little mount of electric power, the liquid refrigerant in the compressor will be pumped into high temperature and high pressure gas. After flow through the heat exchanger, the heat will be released to heat water to satisfy the user's demand. After that, the refrigerant become middle temperature and middle pressure liquid. The refrigerant continues moving to the expansion device and becomes low temperature and low pressure liquid. When flowing through the evaporator, the refrigerant will be evaporated to gas and back to the compressor. The cycle starts again.




In the condition of producing the same volume of hot water, Apricus heat pump water heater only consumes ¼ electric power when compared with electric water heater. For users, it can reduce a lot of daily expenditure. Because of its energy saving and environmentally-friendly, air source heat pump water heater has been regarded as the fourth generation water heater.

As a professional heat pump water heater manufacturer, Apricus provides 4 kinds of products, they are all-in-one heat pump water heaters, top-kits, external heat pumps and split heat pump water heaters. All of them serve for different groups for different requirements of different occasions like hotels, hospitals, SPA, holiday centers.
