Air Conditioning System Fundamentals

Craig McGladrey from AC Silverstack explains how to use a temporize formula to measure airflow in an air handler with electric resistance strip heating. The video covers the setup for measuring voltage, amperage, and temperature rise, along with safety considerations. It demonstrates calculating airflow using the formula and provides additional resources for further learning.

What is the primary purpose of using a temporize formula on an air handler with electric resistance strip heating?

• To measure the airflow

• To calculate the power consumption

• To determine the efficiency of the system

• To adjust the temperature settings

In which systems can the temporize formula be applied according to the video?

• Only in electric resistance heaters

• In electric resistance heaters, gas furnaces, and wheel fired furnaces

• Only in gas furnaces

• In all types of heating systems

What type of temperature sensors are recommended for taking readings in ducts?

• D type temp sensors

• A type temp sensors

• B type temp sensors

• C type temp sensors

Why is it important to use large wires when measuring amperage?

• To prevent overheating

• To ensure accurate readings

• To make the setup more visible

• To reduce power consumption

What should be done before covering the blower motor compartment?

• Switch the taps for heat and cooling

• Check the voltage supply

• Turn off the power

• Calibrate the temperature sensors

What is the significance of the CFM measurement in air conditioning systems?

• It determines the system's power consumption

• It indicates the airflow efficiency

• It helps in calculating the cooling capacity

• It measures the system's noise level

What is the ideal CFM per ton of capacity for a cooling system?

• 500 CFM

• 400 CFM

• 300 CFM

• 200 CFM

What could a continuously rising temperature differential indicate?

• The blower motor speed is too high

• The temperature sensors are faulty

• There is an airflow restriction

• The system is operating efficiently

What should be done after completing the airflow measurement process?

• Leave the system as it is

• Revert the blower taps to their original settings

• Increase the blower motor speed

• Remove all safety equipment
