Enhancement of heat pump performance by using radiant heating and cooling panels.

Author(s) : KILKIS B.

Summary

Two design studies were carried out. An air to water type vapour compression heat pump used for indoor radiant heating in a 320 m2 residential home revealed that the design heating load was decreased by 35%, supplementary boiler was eliminated, and the COP was increased by 20%. For a solar-absorption cycle heat pump used for sensible cooling of a solar house with 81 m2 net living area, the exergetic analysis indicated an overall improvement of the performance of the heat pump and solar collectors. Sensible cooling is accomplished by radiant floor panels. A 3.5 kilowatt water-ammonia absorption heat pump and 30 m2 flat plate collector area is required. The system also provides domestic hot water. The design analysis indicated that with radiant ceiling cooling, the peak cooling load will be shaved by about 25%.
