Solar water heaters and air-source heat pump water heaters are two widely used water heaters, their own characteristics fully meet the needs of users in different regions. So, specifically from the structure, working principle, mode of operation and so on, what are the similarities and differences between the two? Please look at it with Xiaobian it! Detailed solar water heaters and air source heat pump What are the similarities and differences First, what is the heat pump? There are several heat pump? A: The heat pump is a kind of high-grade hot equipment that can obtain low-grade heat from the air, water or soil in nature, Sources are generally divided into air source heat pump, water source heat pump and ground source heat pump three. The name of the heat pump is a vivid analogy of its principle, that is, it is a "pump," which carries "water" instead of water, gas and oil. It is not a thermal energy conversion device but a heat transport device, so its efficiency is not limited by its time-to-energy efficiency (100% limit). Second, the heat pump according to what principle of heat? A: The heat pump equipment set a heat-absorbing medium ;; refrigerant, its evaporation temperature below minus 20 ℃ with the temperature difference exists between the outside world, therefore, the refrigerant can absorb the heat , Evaporates and evaporates inside the evaporator, increases the temperature of the refrigerant through the operation of the compressor in the heat pump device, and then transfers the refrigerant from the vaporized state to the liquefied state through the condenser. In the conversion process, a large amount of heat is released and transferred to the water tank Of the reserve water, so that the water temperature, to achieve the purpose of heating water. Third, the heat pump water heater is a solar energy products it with solar water heaters What is the difference? A: In a broad sense heat pump water heaters are solar energy products, from the working principle does not belong to the traditional solar energy products. It is essentially different from conventional solar water heaters, mainly reflected in the different working principle: Conventional solar water heaters must rely on the direct sunlight or radiation to achieve the heating effect, and if the heat pump according to the principle of Carnac heating, cooling Agent absorbs the heat in the air and the solar radiation energy and compresses the heat by the compressor to exchange heat with the water to achieve the heating effect. Fourth, heat pump water heater operation must use electricity? A: Yes. Heat pump water heaters need to consume a small part of the power to make the machine work to suck the heat in the external environment, and released to heat hot water, but unlike conventional electric water heaters directly heated water, so the power consumption is very small. Its efficiency is not subject to the energy conversion efficiency (100% is the limit). Five, the main features of heat pump water heater is what? A: The main features of heat pump water heaters are: energy efficient, green, safe, reliable, intelligent operation, easy installation, long-lasting, widely used. Sixth, the heat pump water heater to produce a ton of hot water is generally how much power? A: The heat pump in various regions of the country, the thermal efficiency value of each season is different. At a dry-bulb temperature of 20 ° C, the thermal efficiency of the heat pump is about 350% -500%. When the water temperature is increased by 40 ° C, the power consumption of a ton of hot water is about 7-12 ° C. Seven, heat pump water heater suitable for use in what ambient temperature range? A: The heat pump water heater requires the use of the ambient temperature range of 5-45 ℃, below -5 ℃, its COP value is low, there is no significant energy saving effect. A: The application of heat pump water heaters is very wide range, there are a variety of commercial machines for schools, hospitals, factories, hotels, hotels, beauty salons, swimming pools, dormitories and other centralized use of water, There are also various types of household machines designed for families and villas. A: The air source heat pump water heater has the following two shortcomings: ①heat pump is an obvious energy-saving products, but need to consume part of the conventional energy (electricity), non-electric area is not available; ② When the ambient temperature is low (-5 ℃ below), energy-saving effect is not obvious. Ten, the relationship between air source heat pump water heater and solar water heater? A: Both are energy-saving, environmental protection, safety products (solar heat affected by the weather, solar energy is not enough, the need for conventional energy-assisted). There are advantages and disadvantages in the use of performance, each with short length. Their mutual relationship should be complementary rather than who should replace the relationship. The ideal situation is the combination of the two. Although the one-time investment is larger, the energy-saving effect is more significant and the overall economic benefits are even better.
