Investigation on the Economic Possibilities Regarding the Reduction of Energy Intensity for Electrical Household Appliances. Volume 1

摘要

Investigation results concerning the analysis of the energy application for electrical household appliances have not been available up to now. The investigation had the purpose of analyzing the energy consumption of energy-intensive household appliances so that energy possibilities with regard to the effectiveness may be developed. The parts of the effective and of the lost energy are being experimentally determined for the following appliances: large scale hot water tank, washing machine, laundry drier, dish washer, electric hearth, coolers and refrigerators. The influence of the utilization habits on the specific energy consumption and the relationship between the energy application and the application properties are being investigated. On the basis of the investigation results the different possibilities of energy conservation are shown, together with some aspects of economical operation. On the basis of the investigation results also, the potential of the energy conservation, related to practical consumption values, is estimated at about 5-40%, depending on the appliance.
