Solar Air Cooling and Conditioning

SAM doesn’t only heat your home during winter. It can also be used in conjunction with other systems to keep your house cool during the summer months.

We offer 3 options to help cool your home:

  1. Heat Extraction Kits
  2. Cool-In Kits
  3. In-Ground Cooling Kits

The heat extraction fan is powered by the PV panel and controlled by the thermostat supplied with your SAM system. The fan will be installed above the ceiling or high on a wall to remove hot air from the interior of your house.

The cool-in fan can be used to effectively bring cool air into the building, provided that cool air of a satisfactory quality is available from around or under the building (e.i. the sub floor area).


In-Ground Cooling System

In addition to the above setup, the system may be improved even further by burying PE-tubes in the ground and letting the extra fan ‘breathe’ through these. This cooling system will use the cooling effect of the even lower ground temperature to help reduce the temperature indoors. The In-Ground Cooling System enables you to cool your house or office by drawing fresh cooled air in through a series of pipes buried 0.4 – 0.6 metres underground.

Ideally, the air intake should be from a cool, shaded area outside, with the pipes installed in slightly damp ground e.g. where a garden is watered. This is because the evaporation of moisture increases the efficiency of the cooling system. 

The In-Ground Cooling system has proved to be very effective in Australian conditions, not only in helping you keep cool, but also in ensuring good ventilation throughout summer. Our system is an effective cooling solution, that operates on zero running costs or carbon emissions.

Based on customer feedback from earlier installations, we have concluded that on a 35 degree day, the average system can supply air of about 21 degrees into your home, at an estimated airflow of 60-100 cbm/h. 

If airflow is increased, the temperature drop will be reduced, however, as long as the temperature from the IGC is lower than the temperature in the room – higher airflow will generally be more effective. For optimum performance it might be necessary to regulate the airflow depending on outside ambient temperature.

The IGC is normally installed to introduce fresh air from the outside into the house to improve air quality and ventilate the home or office.

It is possible to set the IGC up to recycle the air from the house, which on warm days will increase the cooling effect, but you will miss out on the benefits of introducing fresh air!

IGC: not a Solar Air Conditioner

IGC is not a Solar Air Conditioner, however, it does offer a sustainable natural ventilation alternative to A/C, and it costs nothing to operate. Normally running the IGC will enable you to keep temperatures in one room at an acceptable level without having to spend money on air conditioning.
