In order to collect data at various conditions, the heat
load to the evaporator is supplied by using the hot-water
loop. The water in the tank is heated with a 4.5 kW electric
heater and supplied through the evaporator by the circulating
pump. The condenser rejects heat to the water coming
from a cold water tank. The water is cooled by a separated
refrigeration system using R-22 as refrigerant. The separated
refrigeration system consists of a condensing unit with
a capacity of approximately 2.6 ton of refrigeration, a
capillary tube, filter/drier, sight glass and a helical copper
