DC Inverter Hot Water Heat Pump
Heat pump is an energy-saving device that uses high-grade energy to make the heat flow from the low-grade heat source to the high-grade heat source. As air is the low-grade heat source of the heat pump, the air source heat pump system has neither cooling water system and cooling water consumption, nor power consumption of the cooling water system.
DC Inverter heat pump is a kind of heat pump water heater that uses air as its low-temperature heat source to produce hot water. It is mainly composed of two parts, the air source heat pump circulation system and the water storage tank. The air source heat pump water heater is a device that transfers the heat from the air to the water to produce hot water by consuming part of the electric energy.
When the evaporation temperature is 0℃, using this device to heat the water from 9℃ to 60℃, the COP of the CO2 heat pump hot water system can reach 4.3. With the ambient air as the heat source, the COP of annual average heat supply can reach 4.0. Compared with the traditional electric heating or coal-fired boiler, it can save 75% of the energy.
The dc powered heat pump operates according to the principle of “reverse Carnot cycle”. It can absorb the heat from the air to make hot water through the operation of the compressor system. The specific process is as follows: the compressor compresses the refrigerant, the temperature of the refrigerant will rise after the compression, and the compressed refrigerant passes through the condenser inside the water tank to make hot water, the refrigerant will return to the compressor to carry out the next cycle after the heat exchange. In this process, the heat of the air is absorbed into the refrigerant through the evaporator, and the refrigerant passes the heat to the water to produce hot water.
Because the air water heater absorbs a lot of heat from the air, the energy efficiency ratio is as high as 300%-500%, which is 3-5 times higher than the ordinary water heater, so its heating cost is much less than that of the traditional water heater, and in fact, we are saving power while using this device. Compared with the general water heater, we can save electricity costs by about 70-80% per month by using air source water heater. Because DC inverter hot water heater pump is a kind of regenerative water heater, the hot water is available the moment we start the device, the discharging amount of water is large, and the water temperature is stable. Regardless of the weather, it can automatically supply hot water 24 hours a day, which can meet the needs of the family for hot water.
It can supply hot water for many people once. The heat pump hot water system will automatically shut down when the water temperature reached 55℃, when we begin to use the hot water, there will be cold water entering into the device, and the system will automatically restart until when the temperature reaches a certain value.
It has the intelligent frost-resistant function, which ensures the stable operation of the water heater in low-temperature environment. It can automatically start and stop the frost-resistant function according to the outdoor environment temperature, the evaporator fin temperature, the unit running time and other parameters.
It won’t be influenced by weather conditions such as rainy days and typhoons, and it can work normally at the environment with ambient temperature from -25℃ to 47℃. The inverter water pump can be widely applied to central heating in households, guesthouses, hotels, schools, hospitals, dormitories, residential areas, sauna rooms and other places.
