Retrofit System, Variable-Frequency Drive Cut Energy Costs and Increase Comfort

August 2011
Heating/Piping/Air Conditioning Engineering;Aug2011, Vol. 83 Issue 8, p20
The article focuses on the efforts of the Electric Motor Sales & Supply Co. Inc. (EMS) to reduce the energy costs and increase the comfort of their heating, ventilation and air conditioning (HVAC) system. It notes that the company utilizes a single-zone system that uses one thermostat per HVAC unit to achieve its goal. It adds that the company taps the service of Electronic Controls Inc. to improve the operation of the system in providing heating and ventilation to a space devoted to sales.
