Proof of concept for a building integrated solid state heat pump.

Number: pap. n. 1046

Author(s) : SLUIS S. van der

Summary

A proof of concept has been produced for a solid state building integrated heat pump. This "ActiveWall" heat pump is designed as part of the outer wall of a building, and therefore does not occupy any useful building space. The outdoor side of the ActiveWall has a photovoltaic (PV) surface. The heat pump is based on thermoelectric cooling, which is generally known to have a poor efficiency, but is actually quite efficient at low temperature differences such as those occurring in heating and cooling of buildings in moderate climates. Due to its PV surface, the yearly net electricity use for heating and cooling with ActiveWall is very low. The ActiveWall uses very large heat exchange surfaces and natural convection heat transfer to avoid the necessity of additional fans. Thus, the overall concept does not contain any moving parts, which provides ActiveWall with a long life and low maintenance.
