Catan, M. A.

A prototype water-air solar assisted heat pump (SAHP), has been tested as part of a contract for the development of marketable solar assisted heat pumps. The steady state test results indicate that the nominal performance goal for the prototype, COP of 6 to 90/sup 0/F entering water temperature, was achieved. The transient and cycling tests of the Northrup prototype are described. Tests were performed while the unit cycled under a conventional and modified control mode. Results indicate that cycling performance can be significantly enhanced by operation under the modified control mode where the supply fan is run after the compressor is turned off to extract heat still available at the end of the duty cycle.
