| Abstract: | This Paper presents the design and experimental results of a compression heat pump with solution circuit (CHSC) that has been constructed at the Swiss Federal Institute of Technology. The CHSC offers two major advantages over a single fluid Rankine cycle: 1, the heating capacity is easily varied by a large factor by adjusting the composition of the mixture; and 2, the approximation of the Lorenz process allows for substantially high COP values in cases with gliding temperatures. The test plant heats water from 40 to 70°C and cools water from 40 to 15°C. The heating capacity can be varied from 5 to 15 kW. A COP of 4.3 was measured, representing an energy saving of 23%, compared with a good single fluid Rankine cycle. Measured heat and mass transfer coefficients are presented and discussed. |
