Hi
few question ran accross while understanding the relation of TD Vs Evaporator capacity .
with increase in TD the Refrigeration effect also increase , For eample an evaporator with TD 10degF delivers 12000btu/hr , with 15degF it delivers 14000 btu/hr approx and increases so on as the TD increases.( As i understand the Selection of TD will be based on the application /produced to be stored, humidity requirement etc). My question/doubt here is
1. How can we increase the TD in evaporator ? it with expansion valve
2. if it is with expansion valve , will their be any effect on superheat setting
3. The running cost/compressor running hrs of refrigeration system in case evaporator with high TD less compared to evaporator with low TD.
kindly suggest/help
Regards
