Getting to the dewpoint
Ventilation unit coupled evaporative cooling and heat recovery
Entitlement to the interior comfort increases and with him many times, the power consumption for air conditioning. As part of a research project now a ventilation system has been developed that combines indirect evaporative cooling with heat recovery and thus very efficiently ensures pleasant room temperatures. The principle of operation of the new equipment and test results in a demonstration object summarizes the BINE project information together "office building with fresh air cooling" (09 / 10).The most important component of the ventilation system is a highly efficient counterflow heat exchanger - a development of marketable, indirect evaporative cooling systems. he achieved by an improved geometry and air guidance, the use of new materials and a special surface coating to cool to near the dew point. This allows the room temperature to reduce up to 6 K. is cooled with water - in a conventional refrigerant can be dispensed with. Measurements in a demonstration building show that the new ventilation system is able to maintain the supply air to rooms to approximately 20 ° C.
