Heating Capacity Graph - Delta Temperature

In order to accurately read the Heating Capacity of an FCX fan coil, we must first determine what our water-in temperature will be as well as our entering air temperature. Once that has been determined, we then look at what our water flow rate which will be represented in gallons per minute OR litres per hour.

We use the term ‘Delta T’ to determine the temperature of our heating capacity. The ‘delta Tº’ is the difference between our in-water and the temperature of the entering air.
