CLOSED GREENHOUSE COOLING WITH WATER DROPLET CURTAIN

J. Huttunen
An open water/air heat exchanger, called Novarbo droplet curtain, has been developed for closed greenhouse cooling. In pilot tests in a commercial greenhouse, a droplet curtain equivalent to one kW of electrical power provided a cooling power from 120 kW to more than 200 kW. The greenhouse could be kept closed during the highest global radiation of 850 W m-2. A computerized model of the system was developed to simulate the performance of Novarbo in other climatic areas.
