The heat rejection capacity of a condenser cannot be influenced by which of the following:

In a refrigeration system at condenser there will be a huge change in pressure (significant pressure drop occurs):

The change in enthalpy that occurs in the _____ is called the refrigeration effect.

Condensers run by _______ is capable of overcoming the higher static-pressure losses associated with duct-work:

The system without sub cooling must evaporate substantially _____ refrigerant within a larger coil to produce the same capacity as the system with sub cooling.

A reduction in condensing pressure will _____ the power required to compress the refrigerant.
