The basic knowledge popularization ------ air source heat pump water heater
1, air source heat pump hot water (device) unit is a kind of what?
The device is a kind of all new production of hot water and energy saving equipment, it will absorb heat from the air heating water to a maximum of 55 ℃.It as a central hot water equipment widely used in hotel, hospital, factory, hotel, sauna center and residential area, such as collective type water units and villas, family, beauty parlor, and other small units with water.
2. what is the working principle of air source heat pump water heater?
Air source heat pump water heater unit by the heat pump heat exchanger choke heat absorber heat pump unit constitute a circulation system, etc.HTM (also referred to as refrigerant) under the action of heat pump circulating in the system.It finish gas booster in heat pump heating process (temperature up to 100 ℃), it into the heat exchanger after the release of the high-temperature heat to heat water, oneself are cooling and translated into liquid flow at the same time, when it runs to the heat absorber, rapid heat evaporating liquid into a gas again, at the same time temperature dropped to minus 20 ℃ to 30 ℃, then the air surrounding the heat absorber will continue to pass the low temperature heat to heat medium.HTM constantly cycle is to realize the low temperature of the heat in the air into a high temperature heat and cold water heating process.
3. Air source heat pump water heater units compared with other water heater unit what are the advantages?
Operating cost minimum: air heat pump hot water unit high efficiency, energy saving, cost is about in my unit (device) of 1/3 ~ 1/4, 1/2 of the fuel and gas hot water equipment, electric auxiliary two-thirds of the solar water heater.Conform to the requirements of environmental protection: to environmental requirements higher and higher, the vast majority of cities not only banned high coal dust and gradually to relish diesel will also be banned.Gas, electricity and natural energy is actively advocating and popularizing.A gas hot water system comprehensive small investment: gas hot water system need only more expensive gas hot water equipment, water and pay large charge of compatibilization and equipment installation.This makes the gas hot water system investment are spectacular.Safety: air heat pump hot water unit (device) is flammable, also not direct electricity to heat water, absolute safety.
4. Air source heat pump water heater units need electricity, operation cost will be high?
Air source heat pump water heater units consumed electricity is driven heat pump work, only have the effect of prompting HTM circulation movement, due to the large amounts of heat from the air into the system, the consumption of energy is more than heat pump for hot water electricity and the ratio of the two energy can reach more than 3 times, namely the electro-thermal conversion rate reached more than 300 ℅.That is to say, the air source heat pump water heater units system heating is the main energy of the water from the surrounding air, using the equivalent of in (the) set by a third or a quarter of the electric energy can get enough hot water, operation cost is obviously much lower than the electric water heater or electric boiler unit.
5. Air temperature so low how it can heat water to 55 ℃?
Usually, we always think that heat from the hot reservoir flow to the low temperature heat source, and only under 45 ℃, the temperature of the air especially cold winter if you want to use air directly heated water is impossible.But the air source heat pump water heater units with special equipment, can be achieved from the low temperature heat in air and translated into the process of high temperature heat, and by using high temperature heat heating water to 55 to 60 ℃.
