WebThe design temperature, along with the design pressure, fluid characterization and other technical-economical requirements, is a critical parameter in the design and material selection of process equipment, … WebThe design temperature of process equipment is usually the higher of: the maximum normal operating temperature plus a margin (typically of the order of 25°C); or the …
WebSimply put, the floor surface temperature is equal to the room setpoint temperature plus half the required upward BTU/h/ft2load. For bedroom 1: 2(19.8 BTU/h/ft ÷ 2 BTU/h/ft2) + 65°F = 74.9°F floor surface temperature. The formula used to calculate the floor surface temperature is precise and is supplied by the design program. WebIf the water temperature drops to 50°F, the required flow rate for this equipment in the heating mode expands to 5 GPM/ton (= 15 GPM total). With a 45°F source water, the same unit now requires a flow rate of 10 GPM/ton (= 30 GPM total). Water temperature has the opposite effect in a cooling mode.
