How do you calculate the temperature rise in an HVAC system?

• A. Return Temp - Supply Temp
• B. Supply Temp + Return Temp
• C. Supply Temp - Return Temp
• D. Supply Temp × Return Temp

Answer: (C)

To calculate the temperature rise in an HVAC system, you need to determine how much the temperature increases as air passes through the system. This is done by taking the supply temperature, which is the temperature of the air coming out of the HVAC system, and subtracting the return temperature, which is the temperature of the air that is coming back into the system. The formula used is: Temperature Rise = Supply Temperature - Return Temperature. This approach effectively gives you the difference in temperature, which indicates how much the air has been heated (or cooled) as it moves through the system. In HVAC applications, understanding this temperature rise is crucial for evaluating the performance of the heating and cooling systems, as it helps ensure efficiency and proper functioning.
