PCM filled plastic panels in BTS temperature control

La description

Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance facilities host the most sensitive mission critical electronics. The recommended temperature for these facilities is below *5°C **5°C.

The electrical power required to run the equipment is less than that to cool the facility. Cooling equipment is generally sized for the peak load. Hot spots are often found at various locations within the equipment room due to non uniform air distribution. Backup generators are maintained for the peak load in case of power failure although sensitive equipment can run on stored battery power for a few hours.

Phase Change Material based Thermal Energy Storage Free Cooling System design is available for these communication and control facilities to maintain temperatures below the recommended thresholds. The system uses a specially developed macro-encapsulated inorganic and nonflammable phase change material to store and release energy.

These PCM based TES systems can be designed for one or all below:
Power failure back up: For 4 hours of cooling back up, the diesel generators can be turned off. This application has the potential to save ***0 liters (**5 gallons) of diesel per year assuming, 4 hours of operation per day. This equals to a reduction in carbon footprint of 9.8 tons.

Load Shifting: System can be charged during the night by air conditioning equipment and programmed to switch off during peak demand hours. This operation stabilizes the facilities power demand by shifting the load to low demands hour and reduces its carbon footprint by an estimated 3.3 Tons (estimated for a 4 hour load shift).

Free Cooling: Encapsulated PCM releases absorbed heat when the temperature is lower than its melting temp. With adequate exposure to this low temperature, the PCM completely solidifies. At this state, it operates as a heat sink, absorbing the emitted heat, equivalent to its latent heat capacity.
