It tries than existing 30% or more the performance of heat exchange tubes decaying for being put into single condensation function, equally.It is evaporated, is evaporated using full-liquid type condenser pipe
Performance of heat exchange tubes decaying 35% or more of the performance test than current single evaporator function.Before not increasing number of heat exchange tubes (cost)
It puts, is difficult to meet heat pump unit in Operating condition adjustment to the needs of heating using existing boiling tube of full-liquid type evaporator,
It is difficult to meet heat pump unit in Operating condition adjustment to the needs of refrigeration with condenser pipe using existing full-liquid type condensation.At present in the industry
Also it attempts in same full-liquid type package, is equally steamed using evaporation tube and condenser pipe mixing arrangement and upper layer condenser pipe lower layer
The piping mode of pipe is sent out, to expect that the case tube heat exchanger can satisfy the needs of two kinds of operating conditions of refrigeration and heating, effect is still
It is not satisfactory.
