THE DETERMINATION OF PROPERTIES OF HEATING AND COOLING SYSTEMS IN GREENHOUSE

key words: Antalya, Greenhouse, Heating, Cooling

Summary:

In this study, the heating and cooling conditions of the greenhouses in Antalya were examined and suggestions were made for solutions of the problems that emerged. The Simple Random Sampling Method was used in determining the number of enterprises to be surveyed. The number of enterprises to be surveyed was determined as 246 with a 90 % confidence limit and 10 % error rate. It was determined that the greenhouses enterprises surveyed were heating at 96.34%. It has been determined that the most commonly preferred type of heater in the region is the stove and that the stove is heated only to protect the product from frost damage. In accordance with the data obtained from the research area, it was determined that one stove was used for 1000 m2 greenhouse floor area. It has been determined that 92.68% of the surveyed greenhouse enterprises are trying to reduce the excess temperature inside greenhouse by natural ventilation. It was determined that both the sidewall and roof ventilation were made at 45.93% of the greenhouse enterprises where examined in the research area. It has been determined that the ratio of ventilation area to greenhouse floor area changes between 10 and 15 in 32.52% of greenhouse enterprises and this ratio changes between 15 and 20 in 41.46%. As a result, the heating and cooling properties and problems encountered of the greenhouse enterprises in the study area were determined and necessary precautions to be taken.
