Air source heat pump water heater units and solar water heaters, as necessities of residents' lives, are both devices that use natural and environmentally friendly energy to generate hot water, but they have essential differences. The air source heat pump water heater unit uses air heat as its energy source, but the way it obtains energy is active, so it is not affected by cloudy, rainy, days and nights. The way solar water heaters obtain energy is passive. It relies on direct sunlight to have a better effect, so it can only produce hot water on sunny days.

What kind of device is an air source heat pump hot water (heater) unit?
What is the working principle of the air source heat pump hot water (heater) unit?
Air source heat pump hot water (heater) unit needs electricity, will the operating cost be high?
This equipment of air source heat pump water is high-tech energy-saving equipment for the production of hot water. It absorbs heat from the air to heat water to 65°C (low-end manufacturers heat it to 55°C). As central hot water equipment, drawing on the principle of an all-in-one heat pump, it is widely used in collective water supply units such as hotels, sauna centers, hospitals, factories, and residential communities, as well as small water supply units such as villas, residences and beauty salons.
The air source heat pump hot water (heater) unit consists of a compressor-condenser-throttle-evaporator-compression mechanism into a circulating system. The heat medium (also called refrigerant) circulates in the system under the action of the heat pump. The air source heat pump completes the gaseous pressure increase and temperature rise process in the compressor (the temperature is as high as 80-100 ℃). After it enters the condenser, it releases high-temperature heat to heat the water, and at the same time, it is cooled and transformed into a liquid state. When it runs to the evaporator, The liquid quickly absorbs heat and evaporates and transforms into a gaseous state again, and at the same time the temperature drops to minus 20 ℃-30 ℃, then the air around the evaporator will continuously transfer low-temperature heat to the heat medium. The continuous circulation of the heat medium realizes the process of converting the low-temperature heat in the air into high-temperature heat and heating the cold water.
The air source heat pump water heater (heater) unit is different from an electric water heater (heater) unit. The electric water heater (heater) unit uses the electric heating tube to directly convert electrical energy into heat to heat cold water. The highest conversion efficiency of electricity to heat is about 95℅. However, the electric energy consumed by the air source heat pump water heater (heater) unit drives the air source heat pump to work and only plays a role in promoting the circulation of the heat medium. Because a large amount of heat in the air enters the system, the energy obtained by the hot water is much greater than that consumed by the heat pump. For electric energy, the ratio of these two energies can reach more than 3-4 times, that is, the conversion rate of electricity to heat is as high as 400℅. That is to say: the main energy for heating water in the air-source heat pump water heater (heater) unit system is the surrounding air, and enough electricity can be obtained by using 1/3 or 1/4 of the electricity consumed by the electric water heater (heater) unit. For hot water, the operating cost is obviously much lower than that of electric water heaters or electric boilers.
It is the responsibility of each manufacturer to produce an air source heat pump that meets the standards, so as to ensure the safety of the electricity supply. MICOE conducts many tests on durable air source heat pumps before they leave the factory, and the quality qualification rate is guaranteed.
