Low Temperature Heat Pump Water Heater And Heat Pump Water Heater Difference Jun 30, 2017

  Low temperature heat pump water heater and heat pump water heater difference

  Low temperature heat pump water heater and room temperature (common type) heat pump water heater difference: from the word, the difference between the low temperature and room temperature, refers to the heat pump water heater ambient temperature. As China's north and south latitude span, to the winter north and south temperature difference. The air heat pump water heater is the air as the heat source, the air temperature level determines the air heat pump hot water unit heating capacity, by the compressor technology limit, and now the heat pump water heater is divided into room temperature heat pump water heater, suitable for 43 to minus 7 degrees Celsius temperature Use, low temperature heat pump water heater, suitable for 43 to minus 25 degrees Celsius temperature.

  From the air to heat pump hot water unit structure, the room temperature heat pump water heater and low temperature heat pump water heater compressor system is not the same to the domestic use of a wide range of US  compressor, for example, room temperature heat pump water heater zw series of special heat compressor , While the low temperature heat pump water heater using ZW-ks or VRI-s series of jet enthalpy compressor.

  General compressor and jet enthalpy compressor difference: jet enthalpy compressor than the average compressor more than a gas port, the flash and the economizer generated by the steam from the compressor shell to add a new air intake into the compressor chamber, Reduce the compressor exhaust temperature, reduce the heat pump heat exchanger gas-phase heat transfer zone length, increase the two-phase heat transfer area, improve the heat exchanger heat transfer efficiency. And the system in the production of gas at the same time also increased the refrigerant before the throttle in the subcooling, so that the refrigerant in the evaporator to absorb the heat increased, thereby increasing the heat.

  Application of the "jet enthalpy" technology of low temperature heat pump water heaters, the ability to adapt to low temperature environment greatly improved. Ordinary heat pump in the minus 20 ℃ environment may be difficult to run, and low temperature heat pump water heater even under minus 25 ℃ under the conditions of the use of electric auxiliary equipment can also maintain a stable heating state, heating energy efficiency up to 2.0 The

  Because of the maturity of this low-temperature technology, the current use of heat pump water heater has been expanded, with the exception of a few extremely harsh areas of the environment, has covered 90% of our population living area. Really can be regarded as "north and south can be used, north and south are easy to use.
