It is a refrigeration cycle that works by drawing heat from the evaporator and discharging it to the outside (condenser). The idea behind the project involves recovering this waste heat to preheat domestic hot water (DHW).<\/p>\n\n\n\n<p>This technology is suitable for food businesses with refrigeration units (cold rooms, refrigerated units, air conditioning, etc.).<\/p>\n\n\n\n<p>By installing this technology, which has been available on the market for more than 5 years, the company can save on its electricity bills and reduce its carbon footprint. However, implementing this measure can be complex with a medium-to-long-term return on investment, and requires the temporary shutdown of production during the technical installation stage<\/p>\n\n\n\n<!--more-->\n\n\n\n<p>The exchanger is placed between the compressor and the condenser of the cooling unit. In practice, recovery can be implemented in three different ways:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>External exchanger: an exchanger is connected on one side to the compressor outlet and on the other to the hot water tank (partial recovery)<\/li>\n\n\n\n<li>Internal exchanger: a &#8220;desuperheater&#8221; through which the refrigerant flows is inserted at the bottom of the hot water tank upstream of the condenser<\/li>\n\n\n\n<li>Condensation water collector: all the refrigerant is condensed inside the hot water tank (&#8220;total recovery&#8221;)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<\/li>\n<\/ul>\n\n\n\n<h3 class=\"type-numerotation\"><span class=\"type-numerotation-span visually-hidden\"><\/span>Energy and environmental impact<\/h3>\n\n\n\n<p>The two joint positive effects are as follows:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Energy savings on DHW production because the energy evacuated to the outside is recovered (= waste heat).<\/li>\n\n\n\n<li>Environmental benefits, as the final consumption for DHW production is lower than the initial consumption. It also has a positive impact on carbon footprint, especially if the DHW is initially produced using fossil fuels.<\/li>\n<\/ul>\n\n\n\n<p>The estimated energy savings for DHW are almost 100%, as it is no longer necessary to purchase power. The impact on the carbon footprint will also vary in intensity depending on the initial method used to produce domestic hot water.<\/p>\n\n\n\n<h3 class=\"type-numerotation\"><span class=\"type-numerotation-span visually-hidden\"><\/span>State subsidy application<\/h3>\n\n\n\n<div class=\"wp-block-group has-light-green-background-color has-background\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h4 class=\"wp-block-heading\">State subsidies<\/h4>\n\n\n\n<p><strong>Please note: any application for government or non-government subsidies must comply with the \u201cincentive effect\u201d, subject to compliance with the subsidy conditions.<\/strong><br>To ensure that the \u2018incentive effect\u2019 is respected, no binding commitment (signing a quotation; paying an advance) may be made BEFORE submitting the application file or receiving the agreement in principle from the State or the electricity and natural gas supplier following an application for subsidies.<\/p>\n\n\n\n<p><a href=\"https:\/\/guichet.public.lu\/en\/entreprises\/financement-aides\/regime-sme-packages\/soutien-pme\/sme-packages-sustainability.html\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>SME Packages &#8211; Sustainability<\/strong><\/a><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Financial Aid for small and medium-sized enterprises covering up to 70% of eligible costs for the implementation of a project aimed at reducing the environmental impact.
