Structure and principle of heat pump water heater

How it works Collecting heat energy from air or natural environment using heat-absorbing medium (refrigerant) in the equipment, and rapidly raising the temperature of cold water through the heat exchanger and discharging cold air at the same time. Avoiding the defects that traditional solar products can not work in rainy and rainy days or night can work normally when the outside temperature is above -15 DEG C so that the utility model can be more efficient and energy-saving without occupying the open space. The utility model has the advantages of simple installation and flexible use. Units constitute the operation mode and principle Heat pump water heater is composed of a refrigeration cycle, including the host and the condenser in two parts. The host part includes evaporator, fan, compressor and expansion valve; the condenser is an incubator with condensing coil inside. The refrigerant absorbs the heat of the outside air in the evaporator, releases heat within the condensing coil by the heat pump cycle, and heats the water in the tank. Water tank insulation with closed-cell rubber sponge or polyurethane foam, today's focus: and has good thermal insulation properties. Heat pump unit equipment set a heat-absorbing medium - refrigerant, which liquefied state at room temperature below minus 20 ℃, so there is a temperature difference with the outside world, the refrigerant absorbs the outside temperature, generated inside the evaporator Pressure and evaporative evaporation, through the heat exchanger (heat pump) work, the refrigerant from the vaporized state into liquefaction state, the objective of the heat will be released to the storage tank water. Electricity is only used to make the heat released, rather than used in the direct heating, so the use of electrical very few, in the summer when the temperature is high, the production of a ton of hot water loss of about 5-6 kWh winter cold weather about 20 --25 degrees electricity, the annual average does not exceed 15 degrees electricity. The product features a wide range of sources of heat, including sunlight, rain and air. No matter the day or the night, regardless of sunny sky, windy and rainy, snowing works as usual, weather-free, all-weather throughout the year; can be placed anywhere you specify, without affecting the appearance of the building, only Requires little space, no direct light, installation is very easy. Can be placed in the open, but also can be placed in inconspicuous corners or the basement, and can achieve unmanned operation, automatic temperature control water supply; a wide range of applications: can be used in hotels, restaurants, factories, schools, hospitals, saunas , Beauty salons, swimming pools, greenhouses, farms, laundries, families, etc., can be used alone, but also set to use, different heating requirements, choose a different product line and installation design, but also free access to air conditioning, Meet your requirements from any angle; Excellent CFC-free insulation with only 2% heat loss, longer water temperature, more thermal efficiency than other conventional solar products. Free refrigerant freon, without any exhaust gas, waste water discharge, absolute environmental protection, no gas or electric tank to promote, absolutely safe. Energy-saving effect is obvious, compared with the use of fuel oil, gas, electricity, coal, etc., can save at least 75% of operating costs, allowing you to easily recover the cost. Product Features Energy-efficient: The hot water unit to the air is not low temperature heat source to obtain hot water, power consumption is only 1 / 3-1 / 4 of the electric water heater; with coal, oil, gas hot water unit can save 75% of operating costs. Environmentally-friendly and pollution-free: The system operates without any combustions and emissions and is a sustainable and environmentally friendly product. Safe and reliable operation: the whole system is running without the danger of flammable, explosive, poisoning and short circuit which may exist in the traditional water heater (fuel or gas or electric water heater). It is a safe and reliable hot water system. Long service life, low maintenance costs. Comfortable and convenient, automated, high degree of intelligence.
