Heat Recovery and Efficiency Systems
Dairy hot water costs can be significantly reduced with the installation of a heat recovery and efficiency system. This system captures the waste heat off the refrigeration cycle and heats incoming water to supply hot water storage systems.
On an existing chiller system, add-on features like ‘heat recovery’ are fitted on the chiller as an option before delivery. Two valves sit on the chiller wall and are ready to connect for future usage, and all refrigeration heat exchangers and other components are fitted and ready for that time when heat recovery is connected. The system can run unaffected without heat recovery, allowing the farmer to connect when time and money allows.
Heat recovery is where the heat generated in normal compressor usage is captured and used to heat storage water, which raises the temperature to approx +/- 65 degrees. This heated water is then used to fill the main dairy hot water systems to save money on heating costs by using normal electrical heating elements.
Lancer Ecco Heat™ is an innovative system that captures the superheat waste from large air-conditioning or refrigeration systems and uses it to heat water.
‘With a payback of less than 18 months, it’s a terrific opportunity for businesses to reduce their hot water energy costs’
A Lancer Heat recovery system can reclaim approximately 15–25% of the total heat that would otherwise be rejected by the condenser. A 50 Kw unit running on R404 will provide approximately 48 000 kJ of energy per hour from the hose systems output and will heat 315 L of water, raising the temperature of approximately 35⁰C every hour.
A 16 kW system will raise the water temperature approximately 12⁰C every hour. Heat recovery and efficiency systems are absolutely a money saver for any dairy farm.
