This project aims to recover this heat to preheat domestic hot water (DHW) which is a must in all butcher shops. To do this, a heat exchanger is installed between the compressor and the condenser of the refrigeration unit.<\/p>\n\n\n\n<p>This measure could reduce energy consumption and carbon emissions by 10 to 30%, thereby significantly reducing or even eliminating energy demand for domestic hot water (DHW) production. However, its implementation is complex and will require a temporary production shutdown to during the installation.<\/p>\n\n\n\n<!--more-->\n\n\n\n<p><strong>In practice, recovery can be implemented in three different ways:<\/strong><\/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, allowing for <strong>partial heat recovery<\/strong>.<\/li>\n\n\n\n<li>Internal exchanger: a &#8220;desuperheater&#8221; exchanger through which the refrigerant flows is integrated at the bottom of the hot water tank upstream of the condenser.<\/li>\n\n\n\n<li>Condensation water collector: all of the refrigerant is condensed inside the hot water tank, allowing for <strong>total heat recovery<\/strong>.<\/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:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Energy gain: by recovering the energy discharged outside (waste heat), the energy demand for the production of DHW can be reduced significantly.<\/li>\n\n\n\n<li>Environmental gain: using this waste heat for DHW production reduces the environmental impact, with a particularly positive effect on carbon emissions if the DHW was initially produced by burning fossil fuels.<\/li>\n<\/ul>\n\n\n\n<p><\/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.
