Abstract

The operation of catering type dish washers consumes a lot of electricity, particularly to heat the water used for washing and rinsing of the dishware, and to keep it at the proper temperature level. A heat pump as an energy recovery device seems to be interesting for reducing the electricity consumption. The aims of the project were the study and realisation of a heat pump adapted catering type dishwasher, the measurement of performance and energy consumption of a conventional type dishwasher and of the same dishwasher equipped with a heat pump for heat recovery from the vapour in the machine, as well as the comparison of the results of the two measurement programmes. The report contains a description of the installation, the performance measurements, the difficulties encountered, and the commercial prospects. The comparison with a dishwasher without heat pump indicates that the annual energy consumption for the complete operation of the machine was reduced by 41.5 %, i.e. 35,172 kWh/year.
