COOL-PHASE®

Low Energy Cooling & Ventilation System

COOL-PHASE has a number of practical benefits over conventional cooling systems; no external units are required, meaning the system is applicable even when planning permission is an issue, or outside space is at a premium. The system is modular and scalable in nature meaning it can just as easily be installed in small spaces, scaled up for larger areas, or densely populated environments. The system can be installed as a stand-alone system or alongside the buildings existing HVAC solution, so improving its performance and reducing the buildings energy usage.

The COOL-PHASE system uses the concept of a ‘thermal battery’ to capture and store heat. The Thermal Batteries use the latent heat property of materials to store large amounts of energy, which is charged and discharged by passing air through a heat exchanger. To melt or freeze the material contained within each COOL-PHASE system requires the same amount of energy as to heat up or cool down 32 tonnes of concrete by 1°C.

In the UK, even in the summer, there is a 10 to 15°C temperature difference between day and night time temperatures; this is known as the diurnal cycle. At night cool outside air is passed through the heat exchanger releasing the heat built up during the previous day and recharging the Thermal Batteries. As temperatures rise, warm air is passed through the heat exchanger to provide cooling. The total cooling provided is a combination of the use of the thermal energy stored within the unit, the effects of free cooling, and night time ventilation.

COOL-PHASE works all year round to ensure a fresh and healthy environment, monitoring temperatures and CO2 levels to automatically determine how much ventilation is required.

In winter, the COOL-PHASE system works in reverse, trapping waste heat and using it to warm up cool fresh air entering the building. Whenever the internal temperature exceeds a pre-set level, or at the end of the day when the space is unoccupied, warm air from inside the space is passed through the heat exchanger charging the Thermal Batteries. When ventilation is required, cool air from outside is passed through the heat exchanger, warming the air entering the space and reducing the load on the heating system.
