The heat pump calorimeter is the testing facility to investigate the performance of a heat pump using standard test conditionsobtained f rom domestic or international standard organizations. Conventionally, th e calorimeter consumes so much energy in order to control and maintain the entering water temperature test conditions of the water-to-water heat pump unit. To minimize this energy, a newly designed calorimete r for the water-to-water heat pump was proposed in this study. Experiments were conducted in both heating and cooling modes with variation in capacity and COP of heat pump unit. In heating mode, entering water temperature test conditions of 40 degrees C and 5 degrees C were set for the indoor heat exchanger and outdo or heat exchanger of the heat pump unit respectively. In cooling m ode, entering water temperature of 25 degrees C and 12 degrees C were se t for the outdoor heat exchanger and indoor heat exchanger of the he at pump unit respectively. The analysis of the test results from the ex periment showed that the newly designed calorimeter was able to sav e about 75% or more of the total power consumption comparing with the conventional calorimeter for all heat pump capacity and COP that were investigated.
