This paper introduces the principle of heat pump hot water system, the type of heat pump hot water system and some advantages of heat pump hot water system and other related technical knowledge and application range for the general heat pump hot water system related industries to provide basic knowledge guidance. First, how to understand the "heat pump": Cite a simple example, the car consumes a few liters of gasoline can transport several tons of cargo from one place to another place, Heat pump unit can absorb heat from nature through the heat pump "handling" (electric power-driven heat pump), access to heat for the production and life. Second, the main types of heat pumps: According to different heat sources, heat pumps 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 water heater and conventional solar products are essentially different, mainly reflected in the different working principle: Conventional solar energy products must rely on direct sunlight or radiation to achieve the heating effect, and heat pump Water heater is mainly to absorb heat in the environment to achieve the heating effect. Fourth, the heat pump water heater principle: heat pump water heater unit equipment set a heat medium - refrigerant, which liquefied state below minus 20 ℃, there is temperature difference with the outside world, therefore, the refrigerant can absorb the outside world Of the heat, evaporating and vaporizing inside the evaporator, increasing the temperature of the refrigerant through the operation of the compressor in the heat pump water heater unit, and then transferring 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 transmitted The reason for this product's uniqueness is the reason that the reserve water in the water tank is raised to raise the temperature of the water to the purpose of heating water. Fifth, the heat pump water heater unit heat exchanger, but also in the operation of electricity: but electricity is only used in the drive heat pump to absorb heat from the external environment, and the heat released to heat hot water, rather than conventional water heaters Electric heating water, so little power consumption. Sixth, the heat pump water heater unit and other heating methods compared to what is the advantage: heat pump water heater unit is mainly reflected in: high efficiency, energy saving, environmental protection and 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. Seven, the first phase of the heat pump water heater investment and recovery cycle: Heat pump water heater unit of the first phase of investment than fuel, gas boiler slightly higher, but because of its special energy-saving effect, generally within a year and a half by energy-saving way to recover the cost, Boilers and other heating methods generally have a service life of only five years, while the heat pump water heater unit life of up to fifteen years. Eight, air heat pump water heater power consumption generally how much: Air to heat pump water heater thermal efficiency is generally 330% -500% to 40 ℃ temperature calculation, the production of about a ton of hot water 9-13 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 entire heat pump water heater unit with intelligent control system, users only need to open the power when first used, fully automated operation in the future to reach the user-specified water temperature Automatically shut down, lower than the user-specified water temperature system boot operation, 24 hours a day to achieve full hot water without waiting. Ten, the normal operation of the heat pump water heater unit in winter when the temperature is low: the air heat pump hot water unit has the function of intelligent defrosting to ensure that the unit operates stably under the low temperature environment. According to the outdoor ambient temperature, the evaporator fin temperature and the unit running time Multiple parameters such as comprehensive, intelligent judge automatically enter and exit the defrost. 11, compared with conventional solar air-to-heat pump water heater unit advantages: reflected in four aspects: 1, from the investment side: to achieve the same water supply effect, the funds invested heat pump hot water unit less than conventional solar energy products, and can use the economy Electricity, hot water reserve when electricity is low. 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 direct sunlight, almost zero-cost operation, but unfortunately in the rainy day or night can only rely on auxiliary systems work, statistics show that under normal use, the same amount of water supply, the conventional solar-assisted System power consumption and heat pump water heater unit annual total energy consumption is basically the same. 4, other functions: heat pump water heater unit is not subject to location restrictions, can be placed anywhere, and covers a small space, and conventional solar energy to achieve the same heating effect requires a lot of space, you must also be placed in the air ; Heat pump water heater unit in the hot water can generate air conditioning, can be used for dehumidification, cooling and air filtration and other auxiliary functions. 12, heat pump water heater unit does not need to provide room: heat pump water heater unit can be placed anywhere you specify, does not affect the appearance of the building, with little space, no direct light, the installation is very easy, can be placed in the open, but also Placed in an inconspicuous corner or the basement, and can achieve unmanned operation, automatic temperature control water supply. Thirteen, heat pump water heater unit place: heat pump water heater unit is widely used, has designed for hotels, schools, hospitals, beauty salons, swimming pools, laundry, mining and other design of various types of commercial machines, but also specifically for Home design of various types of household machines, but also free access to air-conditioning, heating can be achieved throughout the year. 14, If you use more than one heat pump water heater, one of the problems do not affect the entire system: Air to heat pump water heater unit has a modular function, the use of grid-connected operation, each heat pump unit can be individually controlled, even if one of them A problem, the maintenance does not affect the normal operation of other units. Fifteen, heat pump water heater unit stable operation: the operation is very stable and reliable, air heat pump water heaters specifically designed for high and low voltage protection, winter frost protection, exhaust temperature over protection, water temperature is too high protection, inadequate water temperature protection, water flow switch protection and Compressor operation and shutdown delay protection. Sixteen, heat pump water heater products compared with the advantages of the boiler: 1, high thermal efficiency: thermal efficiency of heat pump water heater products in the average annual 380%, while the thermal efficiency of the boiler will not exceed 100%. 2, low operating costs: Compared with fuel, gas boiler, heat pump water heater can save 70% of the average annual energy, coupled with lower electricity prices and fuel prices, the advantages of low operating costs have become increasingly prominent. 3, environmental protection: heat pump water heater products without any emissions, the refrigerant used in environmental protection refrigerant R417A, zero pollution of the ozone layer, is a better environment-friendly products. 4, safe operation, no need to watch: heat pump water heaters and fuel boilers compared to run absolutely safe, and fully automatic control, without staffing, saving staff costs. 5, modular installation, easy to add equipment: heat pump water heater products using multiple units parallel installation mode, when the user increased water consumption, ready to add equipment.
