Better savings on energy with Air Star! Air Star ventilation recovers on average 85 % of the heat energy in exhaust air. In a residence of 125 m 2 you can reduce your energy consumption by over 6,000 kwh/year* by installing Air Star! As part of the natural ventilation process, the air is sucked from the house by the thermal force that is created when warm air meets cold air. The warm air, which is lighter in weight, rises and is transported through the exhaust piping. The efficiency of the system is affected by differences in temperature between the indoor and outdoor air. This leads to better efficiency during winter time, when the outdoor temperature is low. In older residences it is common to have the ventilation exhaust pipe mounted around the smoke pipe. The smoke pipe works as an engine and heats the exhaust air, which results in a more efficient natural ventilation system. Nowadays it is common to change from a wood stove to a more modern solution for residential heating, such as a district heating network. This renewal creates another problem. The natural ventilation is highly reduced, as the smoke pipe is not in use. Exhust air This diagram shows two Swedish cities, Malmö and Kiruna. In Kiruna, in northern Sweden the savings reach about 7,750 kwh per year and in Malmö 4,874 kwh per year compared to natural ventilation. If you have mechanical ventilation you will save even more, while the savings will not be as much if there is ventilation with a central heat exchanger unit with ducts. Air Star, however, will always be a good financial solution when it comes to ventilation. Supply air Mechanical exhaust ventilation Indoor temperature 20 0 C Supply air Energy consumption for ventilation Natural ventilation (S) Indoor temperature 20 0 C This is S-ventilation, the most common type in houses in Sweden today. S-ventilation: 125 x 53 kwh/year = 6,625 kwh/year Air Star: 125 x 9 kwh/year = 1,125 kwh/year Savings with Air Star: 5 5000 kwh/year* The dashed line in the diagram indicates that energy consumption from ventilation in smaller residences of 125 m 2 around Stockholm is as follows: The calculation assumes a fully functional ventilation system according to the Swedish standard set by Boverket, The Swedish National Board of Housing, Building and Planning. 110 kWh/year, m 2 100 90 F-ventilation 80 70 60 50 40 30 20 10 0 S-ventilation AIR STAR -2 -1 0 1 2 3 4 5 6 7 8 9 10 Yearly mean temperature Exhaust ventilation (F) This is F-ventilation, where a fan extracts the exhaust air.

Air Star – an invention for ventilation and heat! Compact ventilation units that provide both supply air and exhaust air with the recovery of additional heat. Previously the alternatives were restricted. For those who wanted full ventilation and good economy by reusing the heat in the exhaust air, there were only centrally controlled distribution networks for ventilation. Not anymore. A versatile room unit With Air Star room ventilator installed in the building you will be guaranteed good and economical ventilation. In addition there will be no need for extra heat in most cases, while the unit has an additional heating function. A fresh indoor climate is, however, much more than just the right temperature. With the Air Star ventilating unit you will also have adequate circulation, the right humidity and a good balance between supply air and exhaust air. You will not experience drafts of cold air sinking towards the floor during cool days, and furthermore you will save money with this very economically beneficial way of ventilating and heating a house. Air Star is a ventilation system with incremental heating that works excellently in combination with other heating sources. Do it yourself Our system does not demand any advanced installation or adjustments. The ventilating units are inserted into or onto the interior wall. An ordinary ventilating opening is the only thing that is needed in the facade for achieving the supply and exhaust of air. The units are connected to mains using a plug. During the supply phase fresh air is taken from the outside into the room. The air is heated in the heat exchanger and, if it is needed, from the heating element. This is how our system works Air Star ventilation units are based on well-tried techniques and enhanced with our own innovations. The ventilation units take care of the supply and exhaust air. The heat from the exhaust air is recovered inside an air exchanger and is reused in the supply air. A heating element is included with the unit which not only ventilates but also provides additional heating. There are filters for both dust and particles that purify the air. The concept of Air Star ventilation is based on one ventilation unit which takes care of the ventilation and heating of one room. Each individual unit can ventilate a living space of 20- 35 m2 depending on the model and the system automatically maintains the set temperature. In larger rooms more units must be installed. This gives a flexibility where you can choose an exhaustive installation or point installation. During the air supply phase, outside air is pumped and then blown into the room. This air is heated by the heat exchanger as well as by a heating element if needed. Placement of the ventilation unit SUPPLY AIR The heating element automatically turns on for as long as it needs to maintain the temperature that has been set. The ventilation unit switches in cycles of 30 seconds. This means that there is complete balance between the supply air and exhaust air. The exhaust air fan starts at the same time as the supply air stops. The exhaust air runs through the air exchanger and recovers 85 % of the heat energy from the exhaust air. The heating element is turned off at this time. EXHAUST AIR Air Star works as a lung, meaning that the supply fan and exhaust fan run alternately. When the exhaust fan runs, a flip valve closes the air inlet and opens for air exhaust. Placement of the ventilation unit
