Tiivistelmä
The purpose of this study was to build a case-style business analysis regarding energy cost and savings in the professional dishwashing process.
The market, dishwashing process and the behaviour of the user and manufacturers were studied, along with the details of the machine and the process. The research showed that there is no clear way to compare, for example machines with each other due to lack of standardized comparison rules or even guidelines.
However, the research concluded common result in energy loss during the dishwashing process mainly from convection and through hot air inevitably due to poor insulation and the design of the dishwasher. Also the room temperature in which the items to be washed, had clear effect on the relative need to heat the water thus consuming energy.
The savings model was built by combining the average data from outlined professional dishwasher type and the collected data from customers around Pirkanmaa. It revealed an opportunity to reduce energy consumption in relation to the energy price, by modifying the users pattern of working – for example by bringing in training and optimizing the use of the dishwasher.
