Even if the COP in indirect systems is normally lower than in direct systems, this is partially compensated by the higher efficiency of R290. Still, the nominal COP might be a bit lower in water loop systems above 32 \u00b0C ambient temperature, although if we consider seasonal efficiency, in an indirect condensing water loop system the compressor would condense lower as a direct expansion system would normally force a higher condensing pressure by regulating the rotational speed of the condenser fans.<\/p><p>The following graph shows a comparison between a semi-compact direct expansion system and a <a href=\"https:\/\/www.intarcon.com\/en\/product\/waterloop-evaporating-units\/\">waterloop evaporator<\/a> where we have considered each additional energy consumption (air cooler and circulation pump). Although an indirect condensing system is around 25% more expensive than a semi-compact solution, it shows that the initial cost overrun can be recovered in a moderate payback period.<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-37044 \" src=\"https:\/\/www.intarcon.com\/wp-content\/uploads\/2021\/11\/consumo-anual-energia-waterloop-en.jpg\" alt=\"Annual energy consumption \" width=\"565\" height=\"344\" srcset=\"https:\/\/www.intarcon.com\/wp-content\/uploads\/2021\/11\/consumo-anual-energia-waterloop-en-400x243.jpg 400w, https:\/\/www.intarcon.com\/wp-content\/uploads\/2021\/11\/consumo-anual-energia-waterloop-en-367x223.jpg 367w\" sizes=\"(max-width: 565px) 100vw, 565px\" \/><\/p><p>Thanks to these advantages and benefits, waterloop evaporators are expected to replace traditional refrigeration systems as the definitive, efficient and safe solution.<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-63912 size-full\" src=\"https:\/\/www.intarcon.com\/wp-content\/uploads\/2022\/06\/CTA-Solicitar-Asesoria-EN.webp\" alt=\"Technical Advice INTARCON\" width=\"1191\" height=\"347\" srcset=\"https:\/\/www.intarcon.com\/wp-content\/uploads\/2022\/06\/CTA-Solicitar-Asesoria-EN.webp 1191w, https:\/\/www.intarcon.com\/wp-content\/uploads\/2022\/06\/CTA-Solicitar-Asesoria-EN-768x224.webp 768w, https:\/\/www.intarcon.com\/wp-content\/uploads\/2022\/06\/CTA-Solicitar-Asesoria-EN-640x186.webp 640w, https:\/\/www.intarcon.com\/wp-content\/uploads\/2022\/06\/CTA-Solicitar-Asesoria-EN-400x117.webp 400w, https:\/\/www.intarcon.com\/wp-content\/uploads\/2022\/06\/CTA-Solicitar-Asesoria-EN-367x107.webp 367w, https:\/\/www.intarcon.com\/wp-content\/uploads\/2022\/06\/CTA-Solicitar-Asesoria-EN-600x175.webp 600w\" sizes=\"(max-width: 1191px) 100vw, 1191px\" \/><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\r\n\t\t\t\t<\/div>\r\n\t\t\t\t\t<\/div>\r\n\t\t\t\t<\/section>\r\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>If we look at the commercial refrigeration sector in the cooling capacity range, we can see that propane (R290) has been confirmed as the best natural refrigerant in small commercial equipment such as refrigerated cabinets, display cabinets and compact commercial units for small cold rooms in industrial kitchens and supermarkets.
