A water economizer in a chiller plant may precool/reduce lift by using (conceptual) which resource when it is “cooler” than the condenser or cooling tower approach allows?
Choices
- (A) Condenser or cooling water loop heat rejection to a cooler source (e.g. cooling tower+HX, river, geo) in shoulder seasons, subject to fouling+controls
- (B) Domestic only
- (C) Steam trap only
- (D) Blower door
Correct answer: (A)
Condenser or cooling water loop heat rejection to a cooler source (e.g. cooling tower+HX, river, geo) in shoulder seasons, subject to fouling+controls
Explanation
WSE: HX in series/parallel, fouling+freeze protection in cold climes.
