Air Conditioners

When temperatures outside climb most people begin to look for a cool and comfortable place to either work, relax, or simply have fun. Air conditioners come in various sizes and shapes, cooling capacities and prices. Most often air conditioner that is seen is the window unit, which is an easy way to cool down a small area at a low cost. People that live in homes usually have a condenser unit in their back yard or on the side of the house. Most often in apartment units there are multiple condenser units that cool down several apartments at the same time. Office buildings, stores, malls and restaurants will most likely have their units on top of their roof, those are called roof top units. Even though each of these machines look different and come at different prices they all work pretty similar.

How it works:

What happens is the warm arm from your house is being removed and recycled back in as cooler air. This cycle continues until the thermostat reaches the desired temperature. Air conditioner uses the evaporation of a refrigerant, like Freon, to provide cooling. The mechanics of the Freon evaporation cycle are the same as in a refrigerator as in an air conditioner.

  1. The compressor compresses cool Freon gas, causing it to become hot, high-pressure Freon gas
    (red in the diagram above).
  2. This hot gas runs through a set of coils so it can dissipate its heat, and it condenses into a liquid.

  3. The Freon liquid runs through an expansion valve, and in the process it evaporates to become cold, low-pressure Freon gas
    (light blue in the diagram above).

  4. This cold gas runs through a set of coils that allow the gas to absorb heat and cool down the air inside the building

Most air conditioners indoor units have filters that can catch dust, pollen, mold spores, and other allergens as well as smoke and everyday dirt found in the air. Most air conditioners also functions as dehumidifiers. Other units use the condensed moisture to improve efficiency by routing the cooled water back into the system to be reused.

Energy Efficient Systems:

Ice cooling systems are one way that businesses are combating high electricity costs during the summer. Ice cooling is as simple as it sounds. Large tanks of water freeze into ice at night, when energy demands are lower. The next day, a system much like a conventional air conditioner pumps the cool air from the ice into the building. Ice cooling saves money, cuts pollution, eases the strain on the power grid and can be used alongside traditional systems. The downside of ice cooling is that the systems are expensive to install and require a lot of space. Even with the high startup costs, more than 3,000 systems are in use worldwide

Air exchangers

An air exchanger removes your home’s stale indoor air and replaces it with an equal amount of fresh outdoor air. Plus, it recovers heat and moisture from the exchanged air in the winter, and pre-cools and dehumidifies incoming air in the summer. The result: a more comfortable, healthy, energy-efficient home for you and your family.


  • Saves energy during hot, humid weather, by pre-cooling and dehumidifying incoming air

  • Saves energy during cold, dry weather, by recovering heat and moisture from the air that's being expelled

  • Specially engineered for low maintenance and longer life

  • Slide-out filter is easily accessible, and can be cleaned with an ordinary household vacuum cleaner

  • Easy to install in the attic, garage or basement in virtually any position

  • Automatically ventilates your air round the clock — or use the manual control if you want additional ventilation
