PERFORMANCE STUDY OF A - University Of Minnesota
A higher pressure ratio across the compressor results in a lower volumetric efficiency, a lower mass flow rate of refrigerant, Thus the COP of a given refrigeration system depends on its operating conditions. `For this reason, organizations such as ASHRAE ... Read More
Chiller - Wikipedia, The Free Encyclopedia
A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool air or equipment as required. As a necessary byproduct, refrigeration creates waste heat that must be exhausted to ... Read Article
