Summary
With reference to global warming concern, 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. The combination of green properties of hydrocarbons and carbon dioxide with the energy efficiency of heat pump technology is creating good opportunities of environmental impact reduction. A commercially available heat pump dryer, using R134a, and its evolution towards R290 and CO2 application is presented in this article. Dryer working conditions, compressor reliability and efficiency comparison with standard equipments using electrical heaters and between the different refrigerants are discussed, and some experimental results are shown.
