What is the typical, rule of thumb, supply air temperature to a space in a. heating mode? b. cooling mode?

Solution

system for operating at medium- high speed.the system needs only 1200cfm of air in the cooling mode.the system fan will easily be able to achieve this with a small amount of resrerved capacity using a 1/2hp motor.the cooling mode usually more requires air than the heating mode,as a rule of thumb cooling normally requires 400cfm of air per ton.
