Hydrocarbons, heat pumps, home laundry dryers: environmentally friendly appliances.

Hydrocarbures, pompes à chaleur, sèche-linge domestique : équipements respectueux de l'environnement.


As a consequence of global warming, the developed nations must reduce the level of greenhouse gases emissions. Both direct effect of low GWP refrigerant and indirect effect of reduced energy consumption must be taken into account. Isobutane (R-600a) is dominating in the household European market, while propane (R-290) is well consolidated in low-temperature commercial applications, like ice cream chest freezers. On the other hand, the use of heat pumps in dryers, tap water heaters and similar applications becomes to be diffused, and R-134a is the preferred refrigerant till today. The combination of heat pump energy efficiency with hydrocarbons green properties is opening a wide range of new opportunities with a lower environmental impact. A commercially available heat pump laundry dryer, using R-134a, and its evolution towards R-290 applications is presented in this article. Dryer working conditions, compressor reliability and energy efficiency comparison with standard equipments using electrical heaters are discussed, and some experimental results are shown.
