Heating, Ventilation and Air Conditioning

Main applications and potential benefits

Geothermal technology

Geothermal technology harnesses the natural, renewable energy of the sun, ground and water to heat and air-condition buildings.

Solar energy is stored in the ground, which can be used as a heater when it's cold outside and a cooler when it's hot. To convey energy from the ground to a building, or vice versa, a heat-transfer fluid is used. Energy is exchanged between the fluid and the building by means of a geothermal heat pump.

Geothermal technology offers you consistently good performance and top energy efficiency!

Did you know?
46% of solar energy is stored in the ground. Geothermal technology lets you reap the benefits of this natural, renewable energy.

Benefits of geothermal systems
With a geothermal heat pump, you'll enjoy: An average 40% savings in energy costs* A very high coefficient of performance Reduced energy requirements during peak periods Freedom from cooling towers and boilers, with the esthetic and other costs they entail The satisfaction of an environmentally friendly solution
Advantages of electricity
Compare and you will find that electricity could give you: 25% to 30% savings in maintenance costs ** Longer-lasting equipment High reliability Favorable rates * Savings compared to today's prevailing systems. ** Savings over conventional central heating systems.

Heat recovery

Your equipment, stale indoor air and wastewater are all significant sources of heat. Be smart and tap these sources for the heat you need.

Heat recovery includes a number of processes. One of the most common is air-to-air recovery, in which heat from exhaust air preheats intake air by means of a heat exchanger. Other technologies are designed to recover waste heat from industrial processes or from heating systems to heat water or air.

With heat recovery, you can shrink your acquisition and operating costs while optimizing the size and capacity of your heating and air-conditioning systems.

Did you know?
Most commercial, institutional and industrial operations discharge large amounts of heat, 50% to 70% of which can be recovered!

Benefits	Applications
Voici ce que vous offre la récupération de la chaleur : More energy-efficient facilities Lower operating costs Reduced energy requirements during peak periods	A few typical places where heat is recovered: Hospitals and office buildings Waste heat from stale air or water coolers Supermarkets Waste heat from cold-room compressors Indoor pools Heat from moist air in the pool area Ice rinks Waste heat from refrigeration compressors Factories Waste heat from industrial processes

Rooftop units

Using rooftop units is often a highly practical solution. While primarily designed for air-conditioning, rooftop units are also used to ventilate and heat buildings.

To be energy-efficient and provide optimal comfort, such units must be of good quality, well installed and regularly maintained. Based on these criteria, an electric unit is your best bet.

You save while knowing the occupants will have the ultimate in comfort!

Did you know?
You can program the opening of a rooftop unit's air intake vents to suit your needs.

Benefits
Here's what an electric rooftop unit has to offer: Much less wasted space Flexible adjustment of operating parameters, which can lead to considerable savings on electricity Very affordable price Control over hours of operation Location-specific temperature settings
