How does an economizer work on a chiller
WebMay 19, 2024 · A glycol chiller funnels a glycol-water coolant mixture from the refrigeration unit through thermal heat exchanger piping, absorbing heat from your industrial process and warming the coolant. Next, the warmed coolant returns to the refrigeration unit to repeat the cooling process. WebWater-side economizers can be integrated with the chiller or non-integrated. Integrated water-side economizers are the better option because they can pre-cool water before it reaches the chiller. Non-integrated water-side …

WebEconomizer-based cooling is enabled only when outdoor air is determined to have more cooling capacity than the return air. The method used is according to the available data. When temperature and humidity data are available for the outdoor air and return air, the Comparative Enthalpy method is used. One of the other methods is used if data is ... Web43.3ºC]). This chiller can also operate as a cooling-only chiller at normal condensing temperature. This type of chiller allows the amount of rejected heat to be controlled, although chiller efficiency is compromised for higher hot-water temperatures. Figure 1.

WebA common application of economizers in steam power plants is to capture the waste heat from boiler stack gases ( flue gas) and transfer it to the boiler feedwater. This raises the … WebBy greatly improving efficiency, economizers significantly decrease the cost of running a boiler over its lifetime. Non-Condensing Economizers. In a boiler, the flue gas is the heated gas that exits the boiler via an exit duct known as the flue. The escaping hot gas is a site of heat loss in the boiler system. Non-condensing economizers work ...
