ABSTRACT:

The use of new Phase Change Materials (PCMs) in High Density Thermal Storage as modular " Heat Banks" in the Antarctic infrastructure to assist energy management and significantly reduce energy consumption. PCMs melt and freeze, in much the same way as ice, but at various specific temperatures according to their formulation. They simultaneously store both Sensible Heat and Latent Heat of Fusion and are capable of storing up to ten times more energy, per unit volume, than may be stored at the same temperature In materials such as gravel, masonry, metals, clay and water etc. which have been conventionally used to store Sensible Heat only. These new heat banks provide cost effective means to collect and store waste, rejected and off-peak energy for recycling later, during the peak demand period, to provide " free" space heating, hot water, or process heat and allows significant reduction In the Size of plant and equipment such as generators, heat pumps, boilers etc. Smaller plant and equipment running more efficiently reduces the capital cost of plant and facilitates installation while reducing maintenance, fuel consumption, fuel storage and fuel deliveries. Almost, all energy used In Antarctica IS supplied by fuel oil which must be transported long distances through dangerous waters and then pumped Into bulk storage facilities With the possibility of a major oil spill always present. Efficient energy management minimises cost, and unnecessary transport, handling and storage of large quantities of oil. The paper also deals with other techniques utilising PCMs to provide automatic, passive systems to protect personnel and/or electronic equipment in the event of adverse high or low temperature excursions, due to malfunction of other environment control equipment.

INTRODUCTION

The developing Antarctic infrastructure is small and unimportant when compared to the seething activity of modern, industrialized nations.
