AIR-CYCLE TURBO TECHNOLOGY (ATT)
- GENERAL INFORMATION
Air-Cycle Turbo Technology (ATT)Was create for new generation of eco-frindly HVAC systems, using air as refrigerant and oil-free. The ATT is designes for heating, ventilation, air conditioning of different kinds of premises such as offices, production halls, sport complexes, swimming pools, market halls etc... The special application is railways cars. The ATT is fully variable system, working in summer (Ta=+10 ...50°C) as an air conditioner and in winter (TA=+7 ...-40°C) as a heat pump.
ATT advantages over other systems:
1)Fully environmentally friendly (air is a refrigerant and completely oil-free)
2)High energy efficiency with a low coefficient of recirculation. During cold periods, the COPh is 2.7 ...3.3 in the temperature range +7 ...-40°C, in warm periods the COPc is 1.1 ...1.35 in the temperature range +10...+50°C Both AC and HP are realized with simultaneous ventilation and freh air delivering can be reached up to 100%.
3)Full variability of operation under any weather conditions with high quality of air in a cooled (heated) indoor area (20 ...24°C, fresh air 50 ...100%; relative humidity in summer is 30...60%).
4)No vibrations and acceptable noise level.
5)Low specific weight and dimensions.
6)Easy service.
7)Low installation and operating costs. During exploitation only air filters must be change time-to-time.
