Samenvatting:
An overview is given of existing compact energy (cold and heat) storagefacilities and techniques, based on literature and patents. The amount of
energy that can be saved by storage of heat or cold in office buildings in
the Netherlands is estimated. 17 alternative solutions are presented in
chapter 2 in four categories: perceptible heat, latent heat, energy
conversion, and other. One solution is considered to be the best option: the
water bag. In chapter 3 the design of the water bag for thermal energy
storage is outlined. Attention is paid to the choice of type of foil, the
insulation and the heat exchange. In chapter 4 a state-of-the-art is given
with respect to phase change materials, which can be used in building
materials of walls and ceilings by impregnation. In chapter 5 the fuel
consumption, energy conservation, investment costs and environmental impacts
of several energy systems are calculated: a high efficiency boiler without a
buffer, a system with solar collectors and a high efficiency boiler, a heat
pump as base load and a high efficiency boiler for the peak load, a
cogeneration installation with a high efficiency boiler for the peak load,
and a district heating system grid without an extra peaking system. 81 figs.,
45 tabs., 13 refs.
