This test laboratory is for measuring the capacity and power input of compressor condensing units, by secondary fluid calorimeter on the suction side (method A as per EN standard) for small unit or dry system refrigerant calorimeter on the suction side (Method B as per EN standard) for big unit and refrigerant liquid flow meter on the liquid side method (method D as per EN standard). It consists of a climate chamber, a refrigerant test loop, an auxiliary water system and an electrical control and measurement system, to maintain compressor condensing unit in the specified working condition;
