Colt international mission was to develop 14,000 cubic meters of space in the Hall of the calf about a reliable air conditioning concept. After all, it was necessary to shift to an average volume of about 60,000 cubic meters of air per hour. This is equivalent to a capacity for approximately 60 houses. The Colt engineers opted for the use of two roof ventilation systems of the type Coltair, four evaporative cooler CoolStream type with additional filtering and heating, ten fire gas fans the type of liberator and a multifunctional measuring, control and regulation system (SAIA), which combines all the features. The CoolStream devices are the key elements for the air conditioning of the dining area. Make sure that for example, when outside temperatures of 32 degrees and 40 percent humidity inside the hall outside stable 27 degrees prevail. This corresponds to a reduction of 265 KW heat load.
Effective alternative to conventional air conditioning at the CoolStream is a natural cooling and ventilation system, which operates according to the principle of adiabatic evaporation. Evaporative cooling is an efficient and effective alternative to conventional air conditioning, especially in buildings with large space volumes such as the calf Hall, which does not cost-conscious could be air conditioned by their size alone. The functioning of CoolStream devices is as simple as it is effective: air is cooled by evaporation of water. The energy for the evaporation of the water is taken from the air, this air cools up to ten degrees. While the outside air moves through each with a very quiet, slowly rotating axial fan the cooling medium. At the same time, the medium with drinking water is saturated. The CoolStream a refrigerant such as F(C)kW is not required. An important success factor for this system is an eco-friendly control, a safe circulation, temperature and Renewal of water guaranteed. Control parameters include the time, the outdoor temperature and the respective level of humidity in the air.
