PAST PROJECTS
2 small Q Solar air heaters for a house
Brief:
- Location: Victoria, Australia (370 latitude)
- Single storey house with large eaves
- Installation on a North-facing wall, about 10 degrees azimut offset
- The owner was very satisfied and said:"..the efficiency is amazing..".
Details:
- The owner installed himself the 2 Q Solar ARC, each having an area of 2.1m2
- The units are equipped with AC fans to provide high heating efficiency
- During sunny winter days the solar air heaters provide all the necessary heating.
- The output of both heaters is of up to 4kW (depending on sunshine)
- The solar heaters made savings of about $4/day and paid back in about 3 years
- During 10 years of service, the heaters will provide 1/3 price heat.
- The real savings are larger because the fossil fuel price is increasing.
- Q Solar were surprised to subsequently find out that the owner, Mr M. Whiters is a HVAC engineer who thoroughly tested our solar heaters and has presented this testimonial.
Large Q Solar air heater for a tourist villa in Eastern Europe
Brief:
- Location: Eforie Sud, Eastern Europe (450 latitude)
- Multi-storey tourist villa
- Installation on a South-facing wall with about 15 degrees azimut offset
- The owner said:"...very reliable, do not require maintenance and I make important savings".
Details:
- The task was to provide heat to a villa comprising 30m2 tourist units
- For a unit, we installed a Q Solar ARC having an area of 6m2
- The solar heater is equipped with an AC fan
- During sunny days the solar air heaters provide all the necessary heating.
- In sunny weather it delivers 60-700C air at the outlet; in cloudy weather 30-400C
- The heating power output of a solar heater during sunny days is of about 3.5kW
- The solar heater made savings of about $3/day and paid back in about 2 years
- During 10 years of service, the heaters will provide 1/4 price clean heat.
- The real savings are larger because the fossil fuel price increases.
- The owner, Mr Cristian Mamo has presented this testimonial.
Q Solar air pre-heater for burner
Brief:
- Location: Brisbane, Australia (270 latitude)
- Industrial LPG burner
- Installation on a roof of very small tilt
- The payback time was 2 years.
Details:
- We installed a Q Solar ADU air pre-heater of 25m2 for an LPG burner .
- The solar heater did not need a fan because the burner has a blower fan.
- During 10 years of service, the heater could provide 1/5 price clean heat.
- The real savings are larger, because the fossil fuel price increases.
Large Q Solar industrial drier
Brief:
- Location: Brisbane, Australia (270 latitude)
- Industrial drier for food supplements
- Installation on a horizontal roof
- The beneficiary company has shown interest to order another Q Solar heater.
Details:
- Above is a satelline image of the 307m2 solar heater
- The beneficiary required to dry about 2 tonnes of product from 98% to 4% moisture
- The 4GJ of net heat requirement had to be transmitted through 5.3m3/s of air
- We installed a Q Solar ADU air heater, of 307m2
- An LPG burner compensates during times with low solar radiation.
- Drying tipically takes about 20 hours, therefore we have made and installed a 22 tonnes heat accumulator to allow drying when there is no sunshine.
- The heat accumulator also diminishes the maximum air temperature from 700C to 600C not to destroy the bio-active substances of the product.
- An LPG burner provides backup, but cannot heat the air as uniformly as the solar air heater
- The nominal power of the solar heater is 210kW for the given conditions
- The solar air heater can provide about 3GJ of heat ($135) per day
- If used 3 days/week, the solar air heater could pay back in less than 2 years
- During the 7 years of warranty, the heater could provide 1/4 price heat.
- The director of the company, Mr A. Scott has presented this testimonial.
