Low Energy Fresh Air Ventilation, Cooling and Heat Recovery Unit
Cool-phase provides fresh, cooling and heat recovery, but provides these without the detrimental effect usually associated with AC systems. Utilising the unique properties of a micro-encapsulated Phase Change Material (mPCM), it can provide up to 4kWh of thermal storage with 1kW of cooling or heat recovery at any one time and runs on an average of 40W of electricity. Unlike refrigerants used in AC systems, the mPCM does not deplete the ozone and does not contribute to global warming and at the end of its life the mPCM is simply composted. Constructed form recyclable material, including the PEFC plywood cover, the Cool-phase seeks to provide a green alternative to AC.
Cool-phase was originally created by the University of Nottingham as a research product and several prototype test versions were constructed, but these were similar in size to a chest freezer and utilised heat pipes. However, when Monodraught, became involved in the project we saw the potential and sought to develop the design as a commercially viable product. With the help of Ciba, we now utilise an organic paraffin based PCM to provide latent thermal storage, which not only has a greater longevity but also a greener, recyclable alternative to the salt hydrates used in the early development.
As can be seen from the supplied drawing, the Cool-phase has fitted perfectly within our reception area, renovated earlier this year. It is both aesthetically pleasing and in keeping with the style of the area, but most off all provides a pleasant atmosphere for visitors to be welcomed by when they arrive.
