Climate Control Equipment: The Glossary of Heating

Temporary Heating Requires An Expert; We Can Be Yours

Are you looking for detailed information on climate control equipment? Below is the Axis Air Glossary of Heating Terms and Definitions.

  • CFM – Cubic Feet per Minute
  • CFH – Cubic Feet per Hour
  • BTU (British Thermal Unit) – The amount of heat energy necessary to raise the temperature of one pound of water 1 Degree Fahrenheit.
  • PSI – Pounds of force per Square Inch
  • Infiltration Heat Loss – Heat loss from the structure due to the infiltration of outside air through cracks, pours, and other openings in the structure
  • Transmission Heat Loss – Heat loss from a structure due to heat transmission by conduction, outward through the exterior enclosed materials.
  • Temp-Heat Ventilation Rate – The volume of outside air brought into the structure in cubic feet per hour through the heater(s) divided by the volume of the building in cubic feet.
  • Inside Design Temperature – The maximum desired temperature inside the heated space for the heat loss calculation purposes.
  • Outside Design Temperature – The extremely low outside temperature for heat loss calculation purposes.
  • Outside Average Temperature – the average outside temp during a given heating period for fuel cost estimation purposes.
  • Design Temp Differential – Inside design temp minus outside design temp for heat loss calculation purposes.
  • Average Temp Differential – Inside design temp minus outside design temp for heat loss calculation purposes.
  • Delta Temperature – Inside temperature minus outside average temperature.
  • .018 – BTUs required to raise one cubic foot of standard air 1 degree.
  • “U” Value – Transmission heat loss, expressed in BTUs-per-square-foot of the exposed wall, per-degree Fahrenheit of temp differential.
  • Air Change Rate – The volume of air brought into the structure in CFH through the air handlers divided by the volume of the building in cubic feet
  • Relative Humidity – the ratio of water vapor in the air at a given temp expressed in percentage.
  • Natural Infiltration – Infiltration of outside air through cracks, temporary enclosures or any other openings in the structure causing heat gain and/or uncontrolled ventilation.

Designing and planning for large-scale heating projects over harsh winter conditions require planning, experience, and execution. When significant dollars are spent on equipment and fuel, and when construction schedules are tight and stringent, it helps to understand the many factors that come into making the right choice.
