company. Even on the very hottest summer days the EcoCoolers will supply fresh air cooling at temperatures below 23oC at typically less than 10% of the operating costs of refrigeration. L ast year’s unusually hot summer caused disruption for many factories and industrial facilities where overheating staff and customers resulted in drops in production and sales. While refrigeration systems are often considered too expensive and uneconomical for large space cooling, evaporative cooling offers a cost effective and reliable alternative. Herman Miller, the global manufacturer of office furniture, is a good example of how innovation within energy efficient technologies can not only improve the working environment, but save costs from a company’s bottom line. Nine ECP EcoCooler Small units were installed for the manufacturing space – enabling control of the air temperature and humidity levels in the assembly and manufacturing machine areas; acting as a recirculation system for winter and a ventilator or evaporative cooling system for the summer. The external units are roof mounted so require no floor or external space for installation. All work was carried out during business hours and does not require any downtime. EcoCooling says the cooling solution will improve the working environment for Herman Miller’s staff and deliver energy savings to the 38 | Plant & Works Engineering www.pwemag.co.uk March 2019 Energy, the Environment & Water Focus on: HVAC Cost effective evaporative cooling Utility Usage and Cost per Hour Electrical Consumption £0.120 Water Consumption (average) £0.012 Total Cost per Hour £0.132 Total cost per 168-hour continuous working week £22.18 Energy Consumption: Running costs for a single unit ECP external EcoCooler Small based on an average airflow of 12,000 m 3 /hr are: During colder weather the EcoCooling system works in ventilation mode, outside air is used to cool the building while hot air is extracted out. On hotter days, the natural process of evaporation is used in EcoCoolers to cool incoming air. By evaporating water into the air, temperatures are reduced without the need for mechanical refrigeration, making evaporative cooling an economically viable and green option for large building and process cooling. xpertise... e ol tronc umidity H e aintenanc M e & Se vic umidifiers H diabatic A ehumidifiers D umidifiers H team S r onment. vir the ideal en eate to cr ... o solutions.c .humidity www a onsult & c ye e surv FREE sit • ojects pro t alue dds v A • up al back echnic tull F • a o suit all applic tt quipmen E • Design & support • .uk tion tions Tel: 0208 339 7370 Fax: 0208 339 7371 Unit 5 Russell House, Molesey Road Email: sales@blackfast.com Walton-on-Thames, Surrey KT12 3PE www.blackfast.com
