INVERTER APPLICATION

The inverter adapts in real time the performance of the engine to the needs of the

application by providing only the real power request.

The achievable savings depends on the type of application concerned and on the type of

control system.

For this application the estimated save is 16% of the total HVAC consumption

SUN CONTROL WINDOW FILM

This films use non-metalized nano-

technology to create reflectivity

that's actually lower than glass.

These spectrally-selective films

reject up to 97% of the sun's heat-

producing infrared light and 99,9%

of UV rays.

The film, if not present, could be

applied on ADNOC gas station glass

surface in order to reduce inner

solar radiation and conditioning

consumption.

GEOTHERMAL HEAT PUMP

DEFINITIONA geothermal heat pump is a heating and/or

cooling system that transfers heat to or from the

ground

HEAT

EXCHANGE

It uses the earth as a heat source (in the winter)

or a heat sink (in the summer).

This takes advantage of the moderate

temperatures in the ground to boost efficiency

SOURCE

FEATURES

The temperature in the ground below 6 meters (20 ft) is similar to the mean

annual air temperature at that latitude at the surface.

The temperature beneath the upper 6 meters (20 ft) of Earth's surface

maintains a nearly constant temperature between 10 and 16 °C (50 and 60 °F).

PHOTOVOLTAIC

PLANT

PHOTOVOLTAIC SYSTEM

A photovoltaic system is a power system designed to supply usable solar power

converting light directly into electricity

It consists of an arrangement of several components, including solar panels to absorb and

directly convert sunlight into electricity, an inverter to change the electrical current

from DC to AC, as well as mounting, cabling and other electrical accessories to set-up a

working system.

SUITABLE SURFACES

The property includes N°3 surfaces suitable for PV modules installation
