Plate and Frame Heater Exchanger Temperature delivery accuracy
I am working on a project where a plate and frame heat exchanger supplies domestic hot water to a series of guestrooms in a hotel. High temperature hot water supplies heat to the heat exchanger. We would like to maintain 120 degree F water at the supply side to the guestrooms. What type of accuracy would we expect at the outlet side +/-?
Any recommendations as to controls which we should consider to achieve good temperature control?
