CO2 footprints and solutions for reducing energy consumption;;
Solar air conditioning and solar cooling are currently our main focus in Malta.
We have established an installation and maintenance agreement withHelioDynamics, based in Cambridge, UK. HD has produced the first commercial solar CHP (combined heat & power) system, the HD7.c, as well as the only low-cost medium temperature heat generator, HD7.t.
Each module will deliver:
500W electricity and 3 kW heat @ 90°C
600W electricity + 2.5kW heat @ 60°C.
A single module consists of multiple flat-mirror facets which track the sun very slowly and very accurately. Sensors automatically monitor the position of the sun through each day, feeding information to the controller for the secure drive mechanism.
The mirrors focus the solar rays precisely onto the narrow band of the receiver unit, mounted above the collectors.
The receiver contains high-intensity solar cells, producing electrical power and cooled by water-filled pipes for optimum efficiency. The pipes deliver the heat, @ 60°C - 90°C as required, as hot water, space heating and/or the energy to drive air-conditioning systems.
The system is modular: it can be scaled up to meet changing demand. Up to 8 modules can be driven by a single motor.
HD7.c is designed to be mounted on flat roofs. It can also be mounted on poles above a parking lot or on the ground.
The HD7.c meets the most stringent safety and building-code requirements. It is engineered for a 30-year low-maintenance life in aggressive sand, dust and salt environments. The system has a hail-protection system and is designed to resist winds < 210km/h (135mph).
The modular design facilitates repair-by-replacement best practice. Performance and fault-identification of each installation is remotely monitored using telemetry.
focussing on heat
HD7.t : delivering medium-grade heat < 160°C
A single module consists of multiple flat-mirror facets mounted on a framework to track the sun very slowly and very accurately. Sensors automatically monitor the position of the sun through each day, feeding information to the controller for the secure drive mechanism.
The payback of the capital cost of HD7 equipment is up to 50% shorter than conventional solar competition. After that, the solar energy comes FREE for 22 - 27 years, the balance of the 30-year design-life of HD Solar systems. Maintenance and service costs are negligible.
