In this way, the actual suction pressure of the compression chamber can be reduced by injecting new pressure, and the compression ratio can also be reduced, so the power consumption, exhaust temperature and power will be significantly reduced. At the same time, the heat production will also increase, because the increase of the heat production comes from the increase of the main circuit super cooling.
In this way, because of the lower evaporation temperature and the higher heat production at the lower evaporation temperature, the cryogenic heat pump can also operate stably and reliably in the lower northern region, and the COP is relatively high.
Is it a low-temperature heating heat pump as long as it is equipped with enthalpy-spraying compressor? Frequency conversion heat pump must have good low temperature effect? Can systems with multi-stage compressors operate at ultra-low temperatures?
That must not be!
With cryogenic compressor is not counted, but also with intelligent frequency converter driver and host control program. In addition, improper selection of the "four major components" of heat pump system, lack of attention to details in test matching, imperfect test means, unstable control scheme or not well integrated with refrigeration system will lead to heat pump not being used in some climatic conditions and in some occasions.
OSB heat pump factory-- Low ambient temp heat pump equipped with enthalpy-spraying Copeland brand compressor.
