Chiller load and lift relationship
Chiller load and lift relationship
(OP)
I'm having a hard time trying to grasp this concept between load and lift.
I have read that reduction in load has a small effect on the amount of lift a compressor must do. I assume that since the condenser water delta T decreases as load decrease, the lift and load have a direct relationship.
Can anyone explain the clear concept between load and lift?

RE: Chiller load and lift relationship
Refrigerant systems require and are sized for a known temeprature, so pressure at the expansion valve is constant.
Pressure through the system is referred to as lift from the inlet of the expansion valve to the outlet of the evaporator. Engineers say lift because is is clear that height of a column of stuff is directly related to its pressure.

The capability to use lower ECWT significantly improves chiller efficiency. In fact, greater chiller efficiency can be achieved by lowering lift than by lowering load. The efficiency improvements due to lower lift can be realized in both single-chiller and multiple-chiller installations.
