Heat recovery

Chillers use large amounts of energy and can typically cost 10 times as much to run over their lifetime as their capital cost. Just in the Chemicals and Food and Drink manufacturing sectors, total refrigeration is estimated to consume 5,240GWh/year (over 5% of industrial electricity use)*, equating to carbon dioxide emissions of approaching two million tonnes per year.

* UK Energy Consumption, BEIS and ONS, 2017

There are however ways to minimise the energy usage such as with free cooling or by transferring it into energy that is reused within other areas of your processes and / or buildings. Please see below the following heat recovery options that we can offer.

Heating

Heat recovery systems are perfect for supplementing your facility’s LTHW (Low Temperature Hot Water) heating system.

By utilising the heat energy from your chillers that would otherwise go to waste, you can keep your premises warm, reduce your heating bill and cut back on your company’s carbon emissions.

Hot Air Heating

During operation, ambient air is drawn through the refrigerant condenser of the chiller to extract heat from the refrigeration circuit. This heat is transferred into the air stream and discharges to atmosphere. If the correct extract fans are specified on the chiller, this heated air can be utilised to increase the ambient temperature of your premises instead of being dissipated into the atmosphere. By ducting the air to somewhere where it would be more useful, you can increase the ambient temperature of those areas and save on their heating costs.

Process Requirements

Heat recovery systems can also be used to pre-heat the water supplying your process application requirements, for example, steam generation. Anywhere hot water is required, supplying pre-heated water makes the process more cost efficient.

Hot Water

Heat recovery systems can also provide the energy required to pre-heat your DHW (Domestic Hot Water) system.
