Compressors and condensing units for refrigeration - Performance testing and test methods - Part 2: Condensing units

Scope

This part of EN 13771 applies only to condensing units for refrigeration and describes a number of selected performance test methods. These methods provide sufficiently accurate results for the determination of the refrigerating capacity, power absorbed, refrigerant mass flow and the coefficient of performance.
This European Standard applies only to performance tests conducted at the manufacturer's works or wherever the instrumentation and load stability for testing to the accuracy required is available.
The type of measuring instrument and the allowable uncertainties within which measurements shall be made are listed in Table 2.
