Using waste energy from refrigeration for district heating using heat pumps

Whether a facility is a stand-alone cold storage unit or part of a larger site with production processes; it is entirely normal that all heat from the refrigeration plant is discharged to the atmosphere. However; what if we decided to capture the waste heat and use it? What techniques are available and what options present themselves to harness this assumed valueless waste heat? With around 50% of gas consumption in the UK being for heating buildings opportunities for the economic harnessing of cold storage (or process) waste heat are only going to get better. This presentation will support anyone with any aspirations to harness waste heat.
