Refrigeration and heat pump equipment: General conditions for field testing and presentation of performance (NT VVS 115)

Abstract

  This Nordtest method provides the general conditions as well as references to specific methods to be applied in field testing and presentation of performance for heat pumps and refrigeration equipment. The scope is to provide a framework of suitable test methods ranging from functional tests and simple performance check-ups of small units to accurate commissioning tests of large installations. This test method focuses on the thermodynamic performance in terms of refrigerating and heating capacities, coefficients of performance and operating ranges (i.e. it does not pertain to e.g. mechanical safety, noise etc.).
