Anyone out there able to tell me when they say in the problem statement "Condenser Operating at x deg F" - For the TS diagram, are they referring to the entrance or exit of the condenser, meaning topl left or top right of TS diagram?
I am working on a problem sates (thermal environmental engineering text) Air cooled chiller (R-134) condenser operates at 105F, evaporator operates at 40F with 20 superheat. Motor efficiency 80%, what is the BHP?
I am thinking I need to use Pump HP = (4.715 Q_in_buh)/(12,000 * COP).
