It’s Just Science…

It may look like Magic. but really it’s just Science.

But Science doesn’t tell a very accurate story without all the facts, and that’s the Magic behind Total Performance Diagnostics.  We supply the algorithms, and reporting style that turns scientific facts into usable information.

Heating and Cooling performance isn’t like a static target on a shooting range.  System performance is more like an airplane in a dog fight.  Change one dimension ( like air flow, outdoor ambient, or relative humidity)  and everything else changes (like enthalpy, compressor amperage, and BTU output).  For a better understanding you might want to check out our blog entitled  Cooling Capacity Dynamics.

Iain Milnes of Power Knot in  Milpitas, California, has been gracious enough to allow us to link to the Power Knot web site to help our clients more fully understand some of the science behind system performance diagnostics.  Power Knot is in the business of improving system performance … we’re just in the business of providing the proof that Power Knots’ SRA product really does work wonders.

Power Knot does a great job explaining the basic science behind calculating system performance, and I appreciate not having  to duplicate such fine work. To learn more about the science behind system performance diagnostics from Power Knot, click on any of the topics below:

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 assess the efficiency of your air conditioning system.

How to read and use a psychrometric chart

The psychrometric chart graphically shows the relationship between wet bulb temperature, dry bulb temperature, relative humidity, dew point, and enthalpy. Read this note to learn how to read the chart.

Measuring enthalpy to calculate efficiency

If you want to calculate the amount of heat that an air conditioning system is absorbing, you need to measure the enthalpy of the air.  If you have the system treated with SRA, you can measure the enthalpy after treatment.  This application note explains what is meant by enthalpy, how to measure it, and how to calculate a gain in efficiency.
