WebThe robust dependable performance of the this chiller stems from Carrier’s advanced compression technology, a variable speed, positive displacement tri-rotor screw … Although reducing chiller lift is good for chiller efficiency, there are reasons why many chillers are not able to operate at a low chiller lift condition. 1. High Humidity Issue– Increasing the chilled water supply temperature indeed improve chiller efficiency. However, it also lead to all sorts of high humidity … See more Normally, the chilled water supply temperature is around 6.7°C (44°F). With an evaporator approach temperature of below 1°C (1.8°F), the refrigerant evaporating … See more As mentioned earlier, the lower the chiller lift, the better the chiller efficiency. But, how chiller lift affects chiller efficiency? To explain that, we must … See more Every chiller has an acceptable range of lift pressure. If you are thinking of optimizing chiller efficiency by reducing the condenser water … See more Now, back to the previous question, how chiller lift affects chiller efficiency? To understand, we need to bring up the PH diagram as follow: … See more
