The "heat pump" is a device that can get low level from the air, water or soil in nature It is a kind of energy-saving, environment-friendly and clean heating and hot water equipment. It is a new energy technology attracting worldwide attention in recent years. Keywords: Heat pump technology Heat pump hot water unit Air can be familiar to the "pump" is a bit of energy to improve the mechanical equipment, such as water pump is mainly to raise the water level or increase water pressure, and "heat pump" is a natural from the nature Of the air, water or soil to obtain low heat, power through the work, output can be used by people of high grade hot equipment, is a kind of energy saving, environmental protection, clean heating and hot water equipment, heat pump technology in recent years in the world Concerned about the new energy technology. First, how to understand "heat pump"? For a simple example, a car can transport several tons of cargo from one place to another with only a few liters of gasoline. The heat pump can absorb heat from nature through the heat pump's "handling" (electric power-driven heat pump) Production, life of heat. Second, there are several heat pump? According to different heat source, heat pump can be divided into air source heat pump, water source heat pump and ground source heat pump. Third, the heat pump water heater is a solar product? Broadly speaking, but the heat pump and conventional solar energy products are essentially different, mainly reflected in the different working principle: Conventional solar products must rely on direct sunlight or radiation to achieve the heating effect, and heat pump The unit mainly absorbs the heat in the environment to achieve the heating effect. Fourth, heat pump unit according to what principle to heat? Heat pump unit equipment set a heat-absorbing medium - refrigerant, which liquefied state below minus 20 ℃, and the temperature difference exists with the outside world, therefore, the refrigerant can absorb the heat of the outside world, evaporation evaporation in the evaporator, Through the work of the compressor in the heat pump unit, the temperature of the refrigerant is increased, and then the refrigerant is transformed 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 reserved water in the water tank, High, to achieve the purpose of heating water, which is unique to the product, but also the reason for the market potential. Fifth, the heat pump unit has a heat exchanger, then at run time must use electricity? Is to use electricity, but electricity is only used to drive heat pumps to absorb heat from the external environment, and the heat released to heat hot water, rather than the conventional electric water heater as electricity directly heated water, so little power consumption. Sixth, heat pump units and other heating methods compared to what advantage? Heat pump heat is mainly reflected in: efficient, energy saving, environmental protection, safety. No flammable, explosive gas, no electrical components to promote absolute safety; without any exhaust gas, waste water, waste emissions, absolute environmental protection, heat pump unit annual average operating costs only electric direct heating 1/4, fuel, gas heating 1 / 3 ~ 1/2, 1 / 1.5 of conventional solar energy. Seven, the first cycle of investment and recycling how? However, due to its special energy-saving effect, the cost of heat pump will be recovered within one and a half years through energy-saving mode. The general service life of other heating methods such as boilers is only five years. The heat pump unit life of up to fifteen years. Eight, air heat pump unit power consumption in general how much? Tianshu air heat pump unit thermal efficiency is generally 300% -500% to 40 ℃ temperature calculation, the production of a ton of hot water consumption of about 9-15 degrees. The ordinary electric heating method requires 52 degrees power consumption. Nine, the use of air to heat pump hot water unit and the operation is simple? The use of very simple, the entire unit intelligent automation control system, users only need to open the power when first used, fully automated operation in the future use of the user to reach the specified water temperature automatically shut down when the user specified water temperature lower than the system itself Boot operation, fully realized hot water 24 hours a day without waiting. Ten, low temperature in winter, heat pump unit is functioning? Of course, Tianshu air to heat pump hot water unit with intelligent frost function to ensure that the unit stable operation in low temperature environment, it can be based on outdoor temperature, evaporator fin temperature and the unit running time and other parameters of a comprehensive, intelligent Judge automatically enter and exit the box. Eleven, compared with conventional solar energy, air heat pump unit What are the advantages? Advantages are obvious, mainly reflected in four aspects: 1, from the investment side: If the same water supply effect, capital investment heat pump hot water unit less than conventional solar energy products, and can use economic power, when the power reserve hot water reserve . 2, from the use of: conventional solar products by the weather significantly, rainy days, snow days, night can not work, and heat pump hot water unit regardless of cloudy, rainy days, snowy days, night or sunny can work as usual, Hot water is provided around the clock. 3, from the operating costs, conventional solar energy in the direct sunlight, almost zero-cost operation, but unfortunately in the rainy day or night can only rely on the auxiliary system, statistics show that normal use, the conventional solar energy auxiliary system annual energy consumption Than the heat pump unit total energy consumption throughout the year to be high. 4, other functions: heat pump unit is not subject to location restrictions, can be placed anywhere, and covers a small space, and conventional solar energy to achieve the same effect will need to take up a lot of space, but also must be placed in the open air; Heat pump unit in the hot water can produce air-conditioning, can be used for dehumidification, cooling and air filtration and other auxiliary functions. Twelve, whether you need regular filling refrigerant? Not needed Air heat pump unit is the same as the refrigerator seal, the user has been delivered in accordance with the quantitative filling a good refrigerant, users do not need to self-filling process. Thirteen, why heat pump hot water unit than the electric water heater or natural gas heater more effective? The general heating method is to directly use energy to heat water, electric water heater energy efficiency of about 95%, natural gas is about 75%, while the heat pump unit is driven by electric energy compressor, rather than directly for heating water, The heat actually comes from the environment. Fourteen, absorb heat from the environment Why heat pump will have greater efficiency? Heat pump unit with 1 electric energy can draw 2-3 free heat from the environment, and then use these heat to heat water, consume 1 electric energy is also used to heat hot water, so the final thermal efficiency can reach 300% -500%. Fifteen, whether to provide the engine room? Not required, heat pump unit can be placed anywhere you specify, without affecting the aesthetics of the building, with little space, no direct light, installation is very easy, can be placed in the open, can also be placed in an unobtrusive corner or basement In, and can achieve unmanned operation, automatic temperature control water supply.
