Rooftop Economizer CO2 | HVAC Control – This damper is part of a free cooling system for a rooftop economizer. It is part of an economizer damper system that allows free outside air cooling when the outside air temperature and humidity are ideal. This economizer also works on CO2 control so that if the CO2 levels inside the space rise above a set point the economizer damper opens allowing fresh outside air into the building while venting the air laden with CO2 to the outside.

HVAC Manufacturers | Heating and Cooling - Heating and Cooling Manufacturers are always improving the energy efficiency of their products using innovation and modern technology to help. HVAC manufacturers are required by the government to increase the efficiency ratings of equipment sold. Usually, this is a mandate passed down by Congress that will set a standard for a minimum efficiency of air conditioners and heating systems. Usually, this mandate is the result of manufacturers, the department of energy, and other industry concerns meeting and agreeing to a new minimum that is more 
Learning the Basics of HVAC - To understand air conditioning and heat pump applications you will need to study refrigeration. Both air conditioners and heat pumps use refrigeration to move heat. Air conditioners move heat outside in the summertime using the process of refrigeration. Furthermore, heat pumps move heat in both directions (to the inside in the winter and to the outside in the summer) using the principles of refrigeration.
