REFRIGERATION


regardless of any other benefi t, fi nance and ROI have to be considered. Heat recovery from refrigeration (HRFR) can off er rapid paybacks and so it is a sound investment that off ers real savings in quick order, mainly because it is an add-on to existing infrastructure, not the infrastructure itself. To establish what the potential benefi ts will be for your


client’s organisation, simply fi nd out how much hot water or heating is used. Most grossly underestimate this fi gure so ask for data not just an answer. It takes 1kW of energy to heat 20 litres of water to 50°C from 10°C. If they use 1000 litres per hour at 50C that’s 50kW, which at 20p per kW is £10 or £20,000 per year in an eight-hour day. A typical heat recovery from refrigeration system that delivers 50kW per hour will cost less than £25,000 fully installed. Per pound invested, heat recovery from refrigeration is one of the most cost-eff ective technologies for delivering carbon emission reductions. The same company that installed the system that Rt Hon Graham Stuart MP described as a ‘no brainer’ was installed for less than 50% of the cost of solar PV installed by that same company, and delivers four times the energy – pound for pound an 800% better investment. The same 50kW system and

water usage as described above will save 30 tonnes of CO2 emissions per year. ESG is increasingly high on many organisations’ agendas and heat recovery from refrigeration is a low-hanging

fruit for food manufacturing businesses to take a big step toward its carbon neutral goals. It is cost-eff ective, aff ordable, scalable, has a short lead time and payback and can be retrofi tted with ease. Heat recovery from refrigeration is currently a little-known technology, but one that will increasingly play a part in corporate sustainability stories and can be promoted with your supply chain as a highly aff ordable Scope 3 technology. Heat recovery from refrigeration can attract grant funding, either stand-alone or as part of a larger growth project. It can also be seen as a sustainability bank from which to borrow money for other projects due to the rapid payback it can off er. Planting some seed capital in a nominal account within your accounting system, and using the savings to fund other sustainability projects, can be a great release for justifying such expenditure. If the original seed was a green fi nance loan your capex pot is not aff ected.


HRFR should be on the list for investment in a net zero


future, for any organisation that has refrigeration or air conditioning in its premises. It is aff ordable, scalable, easy to maintain and does not need other infrastructure for it to work. Refrigeration companies that adopt HRFR as a business


stream are well positioned to add value to their clients’ business and growth to their own.
