The papers in this collection have originated from Britain, Eastern
and Western Europe and India, with the delegates coming from
fifteen countries, including a strong contingent from Japan. This
indicates a widespread interest in the application of heat pumps.
The heat pump suffers from an environmental dichotomy. On the one
hand it saves fossil fuel energy, thereby reducing CO emissions. On
the other hand, in the vapour compression form, 2 it generally
employs CFCs which are destructive to our protective ozone layer as
well as contributing to the greenhouse effect. Taking the first,
heat pumps, perhaps have the widest application numerically in the
heating (and cooling) of buildings and an excellent paper describes
case studies concerning three large Norwegian hotels. In these,
heat was pumped from the adjacent river or sea when heating was
required, and during the summer, when cooling became necessary, to
generate domestic hot water. The heat pumps were installed by
SINTEF Refrigeration Engineering, Norway, and have demonstrated
payback periods of about two years. The fractional total energy
saving of the three hotels was 30% as a result, an impressive
figure, indeed. A similar paper by a Belgian architectural
consortium shows how this technique can be successfully applied to
the cooling of a large television complex where considerable
quantities of heat were being generated by the luminaries. In this
exercise the cooling load was successfully pumped to provide hot
water.
