Double Effect Hot Water Chiller
Double effect hot water chiller has higher COP and requires higher hot water supply & return temperature (Typical supply temperature is 160℃) It's suitable for clients who have pressurized hot water piping systems Shuangliang actually made the 1st double effect hot water chiller in the world for Zurick University Hospital
Single Stage Hot Water Chiller
Single stage hot water chiller is commonly used in hot water system with operation temperature below 160℃ Typical applications including CHP system district heating system waste heat recovery system etc The applications in waste heat recovery system help clients significantly improve their energy efficiency and save remarkable cost on energy consumption
Two Stage Hot Water Chiller
If hot water temperature is lower or client wants to recover more heat from hot water (means hot water return temperature is lower or delta T is bigger) depends on different cases two stage hot water chiller will be the ideal option
As the most unique characteristic of two stage hot water chiller dual stage generating evaporating absorbing and condensing process helps it extracting more heat from hot water and achieve bigger delta T operation
Two stage hot water chiller is popular in CHP system for engine jacket water heat recovery (where engine jacket water is not high and/or must be circulated with bigger delta T) If combining with flue gas heat recovery section it can improve CHP system efficiency up to 85%
Composited Type Hot Water Chiller
If the hot water temperature is too low even to operate two stage chiller composited type hot water chiller shall be used to cover the harsh condition
Composited type hot water chiller has lower COP but it can recover extra heat from lower temperature hot water while normal chillers can't do and/or tolerate higher cooling water temperature It provides alternative options for clients who want to achieve the maximum heat recovery
Double Lift Type Hot Water Chiller
Double lift type hot water chiller has very special design than all other type chillers it's used for extreme low temperature heat recovery We will discuss with clients and provide customized solutions case by case
