Solar powered cold storage launched

PT Contained Energy Indonesia has launched a solar powered cold storage solution .

developed and deployed as a stand-alone, off-grid, 100 per cent solar-powered cold storage facilities it uses thermal energy storage (TES) technology in combination with ultra-efficient compressor packages.

The system operates without external power source and thus has zero energy costs.

The first two units 20 m3 installed, one on a  remote island in Wakatobi and another in Pacitan, Indonesia, were designed to keep 1000 kg of fish at -2 deg C, in ambient temperatures of up to 40 deg C, with the capacity of adding and cooling 200 kg of ‘un-iced’ fish per day (for a total cooling load of 30 kWh per day), but the system can just as easily be deployed for agricultural produce, dairy chilling, ice-making and other purposes as well.

It is energized by a 6.4 kWp solar array through a 3-phase Outback inverter system, backed up by a relatively small 10 kWh VRLA battery bank.

One of the unique features of the system is that it incorporates a large volume of Phase Change Material (PCM) in the ceiling, capable of storing 15 kWh of cooling capacity at -4 deg C.

This thermal energy storage technology allows the compressor package to do most of its ‘work’ during the day, when the solar power is available.  This saves a substantial quantity of battery storage that would otherwise be required.

The unit features walls, ceiling and floors constructed from 15cm insulated modular panels, stainless steel door with heating element, aluminium chequered floor plates, lighting and a programmable digital control system.
