It is desirable to test heat pumps over the whole range of conditions under which they will be used. A test facility built at BRE is described in which these conditions may be readily adjusted in a controlled manner, the test procedure for a heat pump unit being carried out in a relatively short time. the heat pump itself is utilized to attain conditions of lower temperature and humidity than ambient. The problems of measuring heat transport in air streams are outlined and ways of overcoming them are given. Particular attention should be given to mixing the air streams. Various aspects of instrumentation of such a test facility are discussed.
