The ADsorption chiller offers huge energy and carbon saving potential, not only within a trigeneration application (i.e. combined cooling, heating and power) but also in any application where an abundance of waste heat is produced and a requirement for cooling or refrigeration exists. ADsorption chillers are also ideal for solar thermal applications and can also be used alongside district heating systems. Designed to operate 24/7, ADsorption chillers are programmed by controller sensors, ensuring they operate at high efficiency – even with variable loads. The ADsorption chiller produces chilled water in only seven minutes from start-up, which can then be used for cooling, ADsorption chiller technology Serious concerns for the environment have focused everyone’s attention on the future of our planet. Whether refrigeration or heat rejection. the energy efficient solution Maximised output with minimised impact and lower costs you’re a major retailer, manufacturer, hospital, local authority or commercial organisation, the race is on to reduce energy costs, cut carbon emissions and help protect the environment. Almost all modern facilities use energy to generate the power required for lighting, IT, cooling, refrigeration and other building services. The resultant fuel costs and levels of CO2 produced can be staggering - not to mention the impact on global warming. Introducing ADsorption chiller technology Efficient energy conservation can be achieved by using available waste heat from an ADsorption chiller for various applications as part of a trigeneration system. Most trigeneration systems currently use absorption chillers but in these modern challenging times there is a far better alternative: the ADsorption chiller. ADsorption technology is the way forward in waste heat utilisation. It offers a highly reliable, efficient solution that takes waste heat from the cogeneration process to operate the chiller. Not only does an ADsorption chiller provide continuous operation with remarkable efficiency, it is also safer for the environment and offers much lower life cycle costs. The ADsorption chiller is an exciting addition to Weatherite’s range of energy efficient air conditioning equipment. As the only company in Europe with sole manufacturing rights, Weatherite has the expertise, skill and resource to provide high energy efficient, environmentally friendly solutions to suit our clients’ needs.

The operating principle The ADsorption chiller works on a proven and simple design principle. It consists of four chambers: The evaporator located at the bottom of the machine The condenser – at the top of the machine Two central ADsorption chambers The two central ADsorption chambers contain heat exchangers packed with silica, with a valve between them to allow vapour pressure equalization. Between each central ADsorption chamber and the “evaporator” and “condenser” chambers, valves allow the transfer of vapour when there is sufficient pressure differential. r out te Cooling wa There are three water sources to the chiller: 1 Waste hot water from the cogeneration process r The water flow is directed to the specific alternates between the two central ADsorption areas of the chiller by control valves heat exchangers and drives out the moisture which are automatically sequenced by previously adsorbed by the silica. the chiller’s on board controller. 3 The cooling water supplies the condenser Cooling water out Hot t water ou 2 The evaporator is fed by a constant flow of chilled water return and supply. e Condens The charge of refrigerant (water) within the chiller is circulated around the section and alternates between the two chambers by means of vapour pressure ADsorption heat exchangers.
