The working principle for air source heat pump water heater is to use reverse Carnot cycle principle. Through the work of compressor refrigerant heat absorption and exothermic, realize the use of low temp heat in the air into high temp heat, so that the cold water gradually warms up to 55 deg c.
1) High efficiency and energy saving: high heat collection efficiency, low operating cost: the ratio of output energy to input energy, namely energy efficiency ratio (COP), can be up to 6. The energy efficiency ratio of ordinary electric water heater is not more than 0.95, the energy efficiency ratio of gas-fired and oil-fired boilers is only 0.8, and that of coal-fired boilers is lower, generally only 0.3-0.7. So its operating cost is 67% less than that of gas water heater, 75% less than that of electric water heater, 60% less than that of oil-fired boiler, and more than 30% more than that of electric auxiliary heating solar energy.
2) Green environmental protection: Using special refrigerant for heat pump, no waste gas and waste water are discharged. The whole system also has no waste residue or waste heat discharge.
3) Safety and economy: The heating method has completely separated the water from electricity, and fundamentally eliminated the potential safety hazards such as flammability, explosion, electric shock, dry burning and carbon monoxide poisoning of ordinary water heaters.
4) Modular intelligent control function: according to the actual needs of users, multiple units can be added flexibly to form a hot water supply system to achieve modular control, automatic control to adjust the operation time of each unit and the order of putting into operation. To ensure the consistency of the total operation time of each unit, and to achieve efficient and optimal operation of the whole hot water supply system.
5) Easy to operate: The unit is controlled by a microcomputer and operates automatically. According to the water temp of the water tank and the user’s water condition, it can start and stop automatically without the need for special person on duty.
