TAKE ADVANTAGE OF NATURAL COOLING ThinICE modules can be installed at high levels so that heat goes up but doesn’t come back down. This cooling effect can provide relief to building inhabitants or for electronic equipment. ENERGY If the site is located in a region where there are large daynight temperature swings, then it is possible to provide free cooling by ventilating the room at night to freeze the PCM modules by the morning. The size of the cooling machinery could then be greatly reduced leading to lower emissions, reduced maintenance costs and reduced operational costs. For a standard 595x595mm ceiling tile, two ThinICE modules can be installed offering up to 0.96 kWh/m2 of energy storage. At an installed weight of up to 24kg/m2, most suspended ceilings are more than capable of handling this additional load. These are ideally fitted above a perforated metallic suspended ceiling.

ACTIVE COOLING WITH A PASSIVE SAFETY NET It’s easy to upgrade these passive cooling systems into an active chilled ceiling. This greatly improves the flexibility of a conventional HVAC system. Should, for any reason the HVAC machinery fails the frozen PCM modules offer an uninterruptable emergency relief cooling system giving the facility maintenance team an opportunity to react. This also offers load-shifting capabilities. Load shifting is a strategy, where a proportion of the peak cooling capacity of a system is shifted into off-peak periods. The benefit of shifting cooling into the nightly off-peak is twofold, firstly it is possible to gain access to cheaper electricity tariffs and secondly, the refrigeration equipment can be operated in lower ambient conditions leading to a higher COP.
