Would it be possible to use an underrated evaporator (say design at 30 TOR) for a chilled water system with design capacity of 40 TOR? If this is possible, are there any operation control procedures we need to implement or operational parameters we need to monitor to make sure the set-up would not pose any problems to system auxiliaries such as compressor, expansion valve and condenser. Due to marketing constraints we were forced to use this set up without us really knowing how it will affect the whole system operation. However, we were assured by our local contractor that this would pose no problem as long as system is operated at lower capacity than 40 TOR and initial charging of refrigerant also lower than the standard. Any inputs on this concern would be highly appreciated.
