1. What kind of device is the air source heat pump water heater?
The unit is a new type of equipment for the production of hot water, which extracts heat from the air and heats the water up to 55 °C. As a central hot water equipment, it is widely used in hotels, hotels, sauna centers, hospitals, factories and residential quarters, such as collective hot water, heating units and villas, homes, beauty salons and other small hot water, heating units.
2. How can the air temperature be as low as 55 °C?
Usually we think that heat always flows from a high-temperature heat source to a low-temperature heat source, and the temperature of the air is only below 45 ° C. Especially in the cold winter, it is impossible to directly heat the water with air. However, the air heat pump water heater is provided with a compressor. Through the input of electric energy and the work of the compressor group, the process of absorbing low-temperature heat in the air and converting it into high-temperature heat can be realized, and the high-temperature heat is used to heat the water to 55-60 °C.
3. What is the working principle of the air source heat pump water heater?
The air source heat pump water heater is composed of a heat pump, a heat exchanger, a throttle, a heat absorber, a heat pump and the like to form a circulation system. The heat medium (also called a refrigerant) circulates in the system under the action of a heat pump. It completes the gaseous boosting process (temperature up to 100 °C) in the heat pump. It enters the heat exchanger and releases high-temperature heat to heat the water. At the same time, it is cooled and converted into a liquid liquid. When it runs to the heat sink, The liquid rapidly absorbs heat and evaporates again into a gaseous state, while the temperature drops to minus 20 ° C - 30 ° C, when the air around the heat sink will continuously transfer low temperature heat to the heat medium. The continuous circulation of the heat medium realizes the conversion of low-temperature heat in the air into high-temperature heat and heating of the cold water.
4. Air source heat pump water heater needs electricity, will the running cost be high?
The air source heat pump water heater is different from the electric water heater. The electric water heater directly converts the electric energy into heat energy to heat the cold water, and the electric heat conversion efficiency is about 95 c/o. However, the electric energy consumed by the air heat pump water heater is to drive the heat pump to work only to promote the circulation of the heat medium. Since a large amount of heat in the air enters the system, the energy obtained by the hot water is far greater than the energy consumed by the heat pump. The energy ratio can be more than 4 times, that is, the electrothermal conversion rate is as high as 400 c/o or more. That is to say: the main energy source for heating the water in the air heat pump water heater system is from the surrounding air. It can get enough hot water with the energy equivalent to 1/4 or 1/5 of the electric water heater. The operating cost is obviously far lower. For electric water heaters or electric boilers.
5. How to eliminate the frost in the air source heat pump in winter?
Air source heat pump frosting is one of its drawbacks, so it is easy to cause frosting of external equipment in winter, and it is not easy to clean in winter. The maintenance method is to wrap the external facilities with cotton cloth or warm things to prevent frosting and thawing.
