Abstract

This chapter describes how to choose the nominal power of a heat pump in dependence of the load requirement of the user and the local climatic conditions. Furthermore as the performance of a heat pump is obviously affected by the power required, the full load and part load operations are examined and the load factor is introduced. The chapter describes the methods, provided by the present standards, of evaluating the coefficients of performance and the data the producers have to supply in order to make such calculations.
