British isles: The 1st Uk installation of Carrier’s AquaForce 61XW warmth pump employing minimal GWP refrigerant R1234ze is giving price tag-productive cooling and heating for a person of the country’s foremost vegetable producers.
The 1.2MW technique is predicted to help you save the vegetable producer between £120,000 and £150,000 a yr in heating prices and, with assistance from the Renewable Heat Incentive scheme, payback is predicted inside of two to three several years.
Earlier, the company’s big cold store was cooled by a standard air-cooled chiller with individual LPG boilers delivering heating and warm h2o for the offices and 70 static caravans for seasonal personnel. This program was explained to be expensive to run and important electricity was staying wasted via heat rejected by the chiller.
The business commissioned Stoke-on-Trent-dependent OMNI Warmth and Electric power to structure and put in a more power successful and environmentally-dependable option, centered on minimal-carbon renewable vitality and harnessing waste heat.
“The pretty extensive temperature array, spanning -5ºC for the cold store to 55ºC for domestic sizzling drinking water introduced a certain problem,” noticed OMNI Heat and Power director Bradley Martin, noting that couple of heat pumps could cater for this though retaining efficiency.
The remedy uses the Provider AquaForce 61XW heat pump to harness reduced-quality heat from floor loops buried in the soil, furthermore waste warmth from the chilly shop refrigeration method. Hot h2o generated is piped to accommodation facilities and workplaces by means of a mini district heating program, delivering ease and comfort heating and DHW.
Electric power for the heat pump is supplied by a substantial photovoltaic array on website. This provides up to 1.5MW of energy, generating the facility nearly totally self-adequate in electricity.
“We see massive likely for this option in agriculture, the place there is usually a require for cooling for produce together with heating for seasonal staff and places of work. The Provider method is exceptional in getting in a position to cater for this diverse prerequisite,” said Bradley Martin.
