therefore a power of just Qel=38.4W is applied into the refrigeration circuit via the compressor.
Of the applied electric power Pel only about 16% is used. The compressor has a very low efficeincy in the operating point.
The low efficiency of the compressor occurs mainly because it is only operated at about 10% og its rated power.
The measured values used for the example calcolation were recorded under certain laboratory conditions.
Thermal calculations are always directly dependent on the environmental conditions. The achievable refrigeration and condenser capacities are therefoer highly dependent on the prevailing operating conditions.
