Following a roadmap to renewables and energy saving<\/strong><\/a>, on the pace traced by our latest Tempco Infographic<\/strong><\/a>, I would like to talk about how energy saving<\/strong> can be specifically applied in all of the different thermal machines. Starting with refrigerating groups<\/strong><\/a>.<\/p>\n

I remember when first attempts started on the market to employ inverters in order to adjust the speed of compressors<\/a><\/strong> on refrigerating groups. Inverters are largely employed to regulate speed on electric drives<\/strong>, adjusting the power absorption based on the season conditions. It\u2019s clear indeed that during the summer season, when ambient temperature is higher, a refrigerating group needs the maximum power in order to achieve the refrigeration task required. While during the winter season it requires less amounts of power, due to a series of reasons such as the increased efficiency of the condensation system<\/strong> and the fact that water comes from the production process at lower temperatures.<\/p>\n

The study to implement energy saving on refrigerating groups<\/strong> aimed then at adjusting the speed of fans on condensers using EC motors<\/strong><\/a>, with electronic control, through inverters. This allows the regulation of the speed of fans based on ambient temperature levels.<\/p>\n

The same kind of adjustment was then possible on compressors<\/strong>. Let\u2019s make an example to explain why: when sizing a refrigerating group<\/strong> employed to regulate the temperature of pharmaceutical reactors<\/a>, the plant must be engineered to provide the maximum capacity required to achieve the cooling task. But there will be also a series of intermediate steps not requiring the maximum design refrigerating capacity<\/strong>, but maybe only at 50% or 30.<\/p>\n
