Supply air equipment - air heat pump equipment - consumer and commercial air-way ring Dongguan ..

The dominant species on the heat pump water heater market many types of heat pump water heater, there are solar boost type, water and air source three series. Solar heat pump to boost the use of heat pump and solar technology combined with a heat pump technology; water source heat pump is the use of a certain temperature water (20 ℃ above) as a heat source to the refrigerant for the media, after the water in the heat absorbed by the compressor compresses heating, cold water through the heat exchanger to exchange heat with the heating and preparation in order to achieve the purpose of hot water, water source heat pump must have a certain water temperature and flow; water source heat pump air heat pump with a similar method to obtain heat from the air to heat water. Three kinds of heat pumps, air heat pump subject to minimum conditions, the development of the largest space. Air to air heat pump water heaters, heat pump water heaters mainly by the compressor, heat exchangers, axial fans, holding tanks, pumps, tank, filters, electronic expansion valves and electronic automatic controller and other components. After power, axial fans start to run, outdoor air heat exchange through the evaporator, the air temperature is lowered after being removed from the system fan, while inside the evaporator refrigerant absorbs heat of vaporization is sucked into the compressor, the compressor this kinds of low-pressure refrigerant gas compressed to a high temperature, high pressure gas into the condenser, forced circulation of the water pump is also through the condenser, refrigerant sent after being heated for users, and is cooled into a liquid refrigerant, through the expansion of the liquid the throttle valve again after cooling flows into the evaporator, and so forth cycle work, heat in the air is constantly "pump" to the water to holding tanks where the water temperature gradually increased, and finally reach about 55 ℃, just right for people bathing. Air heat pump is one of the world's most advanced energy products. With the rapid development of economy and improvement of people's living quality, domestic hot water has become the people's daily necessities, but the traditional water heater (electric water heaters, fuel, gas water heaters) have high energy consumption, high cost, pollution and other shortcomings; and energy saving solar water heaters running and restricted weather conditions. Air heat pump heating principle with the traditional solar water heater distinct air heat pump with air, water, solar and other low-temperature heat source, air source heat pump absorbs heat with electricity powered from a low temperature side to heat domestic water, hot water through the cycle system directly into the user as a water supply or the use of fan coil heating a small area. Air heat pump is the school dormitory, hotel, bath center and other places of large, medium and small water supply systems concentrate the best solution.
