DEVELOPMENT OF ENERGY EFFICIENT ELECTRICAL HOUSEHOLD APPLIANCES. PART TWO - COOKING
The work has been focussed on the development of a small, highly insulated electric oven, low heat capacity hot plates and an accurate electronic thermostat for electric hot plates. A 50% reduction was aimed at + in comparison to the 1975 annual electricity consumption for cooking. Radiant rings were not included in the study. Two versions of a prototype oven have been built, LEO1 and LEO2 (Low Energy Oven 1 and 2). LEO2 has shown an energy consumption around 1/5 to 1/3 of ordinary sized ovens. In experiments with low heat capacity hot plates made of aluminium theoretical calculations have indicated possible energy savings around 20%, but the difficulties in producing such hot plates have proved to be considerable. A significant electricity saving, 20%, may be obtained by supplying electric cookers with an accurate thermostat. This corresponds to an electricity saving of 1% on a national basis. An experimental microprocessor based setup has been built for the investigation of different principles of control. Two principles have been examined: direct substitution in the model equations and prediction of the pan bottom temperature. As yet the results are unsatisfactory, and incomplete, respectively.
