WebJan 1, 2014 · The minimum required COP ranges from 2.40 to 3.06 for air-cooled chillers and from 3.80 to 6.39 for water-cooled chillers. Bas ed on a s et of chille r products …
WebWhen superheating is at its maximum the total COP is 2.5, with minimal superheating the total COP is 3.2. In between, there is linear interpolation. ... The comparison between the predicted and the rated capacity of the chiller over a wide range of operating conditions has already been presented in Table 4.1. It can be seen that the prediction ... ff re7WebAir-cooled chillers are generally simpler than water-cooled chillers. Sometimes, air-cooled chillers are also known as modular chillers because they can be stacked horizontally like legos to increase their total cooling capacity. The available cooling capacity of a typical air-cooled chiller can range from around 10 RT to around 550 RT. dennis workman motorcycle accidentWebCoefficient of performance (COP): Chiller efficiency measured in Btu output (cooling) divided by Btu input (electric power). Multiplying the COP by 3.412 yields the energy-efficiency ratio. ...
