Designing for 42 deg F chilled water supply temperature: does it save energy?
Author(s) : KIRSNER W.
Type of article: Article
Summary
If total head is well above 300 kilopascals, there will be energy savings at full load for designing for lower chilled water supply temperatures at expanded temperature differences. However, whether or not this energy advantage is sustained at part loads will depend on the response of the particular pumping system. Therefore, if the pumping head is below 300 kilopascals, it is probably advantageous from an energy standpoint to maximize chiller efficiency by choosing a high chilled water supply temperature such as 7.22 rather than 5.56 deg C.
