Environmental Project, 951 – Comparisons of Energy Consumption for Refrigeration in Supermarkets

3 Measuring program

Power consumption, compressor and condenser capacity used, suction and discharge pressures of the compressors, the openings of the injection valves, superheat temperature at evaporator outlet, and air temperature of all evaporators were measured on all four systems. The in- and outdoor temperatures and the relative humidity in the shops were also measured.
