How does an economizer work on a chiller
WebThe work is the change in enthalpy from point 2 to point 3 times the flow of refrigerant. Simply, BTU/lb. times the lb./min equals compressor power. Compressors end up with the work of compression as heat in the refrigerant. Open drive motors reject their winding heat in to the mechanical room. WebApr 3, 2012 · A water side economizer helps in the production of chilled water. The savings are a result of the reduced runtime of the chillers. The most common type of water side economizer uses a typical open direct-contact cooling tower with plate and frame heat exchanger. Open towers will tend to accumulate ice in extremely cold weather.
