Performance of R-408A was compared with traditional refrigerant R-502 in low-temperature commercial applications.
Performance tests of R-409A against R-12 and R-401A were conducted to determine the energy efficiency impact of the new refrigerant.
A series of laboratory tests were performed to quantify impacts of realistic ambient conditions on the performance of vending machines. Results showed an increase of 120% energy use for every 1°F ambient temperature increase.
Replacing worn-out gaskets with new, tight fitting gaskets on the main doors of walk-in freezers can save 1117kWh per foot per year.
This project quantified the potential savings when bare refrigeration suction pipes are insulated. With the relatively inexpensive cost of pipe insulation, and the relatively expensive cost of electricity, this easy fix can potentially result in large savings.
