Relationship between condensation and evaporation temperature in a refrigeration cycle: dragging term.

Author(s) : MORENO-RODRIGUEZ A.

Summary

The theoretical model that applies to a refrigeration cycle of a thermal system, made whether from the experimental standpoint or in accordance with design criteria, does not actually take into account that the system behavior differs depending on the very
conditions of the compressor as well as the interaction between both exchangers (evaporator and condenser). Depending on the operating pressure the condensation and evaporation temperatures do not necessarily have any constant differences at all with the
respective environments. In the light of our experimental research, such alleged increase in temperature will be measured and subsequently discussed. The thermal system tested here is in fact unique in that the term that quantifies such a dependence in concept known as “dragging term”, grows higher in accordance with its own operating conditions. It is a Direct Expansion Solar Assisted Heat Pump (DXSAHP).
