The best thing is: Everyone can contribute!
Upgrade it with an AircoSaver
It is a retrofit product that adds intelligence to
air-conditioning systems, which saves KWh and extends compressor life.
It’s Just a Waste of energy!
Package Units (RTU)
This table shows the equivalent increase in the efficiency (Energy Efficiency Rate “EER”) of Air Conditioning installed after AircoSaver. For example, an AC with an EER of 10, taking AircoSaver with savings of 30%, increases its efficiency to an EER of 14.
* Per month data is based on a 30 day month
COMMENTS: The average temperature, relative humidity and heat index were all higher after the AircoSavers were installed which lowered the overall savings. Also, the KW Demand savings was almost 7%, but was not figured into the savings listed above. The data above was compiled from the following sources: CPS Energy monthly electric bills for Jun, Jul, and Aug 2008. The weather data was downloaded from weatherunderground.com station KTXSANAN78.

At each site, air conditioner supply voltage was recorded. Air conditioner power was derived from the formula- (measured volts X measured amps X assumed power factor of .85) = power. Only one site, SD0364 was supplied with three phase power for air conditioners. The three phase power conversion factor of 1.732 was used to calculate power consumption at that site. Pre period average hourly power consumption was compared to post period average hourly power consumption and the result was annualized to determine annual energy savings. No air conditioner performance corrections were made for increased ambient (external) temperature. At eight of the nine sites average temperature during the post period was higher than during the baseline test period. An examination of compressor kW VS ambient temperature showed little difference.
Project Results and Discussion
Average hourly power savings was calculated for each site and extrapolated to annual energy savings. Overall air conditioning savings was 20% of baseline air conditioner energy consumption, and averaged 7071 kWh for the nine sites. Energy savings averaged 6.8% of site total energy consumption.
The Aircosaver control system may be incentivized through the Standard Performance Contract Program at nine cents per annual kWh saved. The incentive is limited to ½ the installed cost, or the calculated incentive, whichever is less.
At an average site electric cost of 14.4 cents/kWh Annual energy savings for installing the AircoSaver at each site is around $1,000 per year.
