SRA – Application Notes

What Is A Ton of Refrigeration?

HVAC systems may be specified by tons. This does not refer to the mass of the unit! Read this note to find out what that means.

Power, Energy, and Efficiency

We are often asked questions about power and energy such as how much energy our LFC uses, how much power the SRA can save, or what is meant by a gain in efficiency. Often the questioner doesn’t understand our answer. This application note defines each of these attributes and should make the answers clearer.

Measuring Enthalpy to Calculate Efficiency

This application note describes in detail how you can calculate the gain in efficiency of a direct exchange air conditioning system before and after treatment with the SRA. The physics underlying the method are explained.

COPs, EERs, and SEERs

These terms define the performance of air conditioning systems. This application note defines these terms and explains how you can use them to asses the efficiency of your air conditioning system.

About the Psychrometric Chart

The psychrometric chart shows graphically the parameters relating to water moisture in air. This application note describes the purpose and use of the psychrometric chart as it affects the HVAC engineer or technician.
