| Among the various vegetables eggplant and gourd family can stand against high temperature environmental condition, about 35$^{circ}C$. However, most of greenhouse farmers are giving up crop cultivation during hot summer season due to extreme temperature, 4$0^{circ}C$ or above, condition of greenhouse interior. To improve this inferior crop growth condition, for nozzle system was installed in the pet greenhouse and the effect of fog system was investigated in order to determine fog water amount and the required fog nozzle numbers according to house volumes. MEE fog nozzle was selected for this Investigation which can produce water particle size of 27${mu}{ extrm}{m}$ with water amount of 100$mell$ at pumping pressure of 70kg/$ extrm{cm}^2$. House cooling test was conducted in the pet greenhouse with one minute fogging and one minute air ventilation without stopping. It maintained 32$^{circ}C$ at the house interior when the atmosphere and the house temperature were 35 and 4$0^{circ}C$, respectively. And, an experimental equation was developed through calculating the changes of relative humidity and temperature with psychrometric equation which revealed the moisture transfer pattern between the house air and fog system. It showed that the required water fogging amounts to reduce 1$0^{circ}C$, 40 to 3$0^{circ}C$, needs 80.7$ell$ for 1-2W(8,350§©) and 99.9$ell$ for 3-2G-3S(10,330§©) type greenhouse with particle size of 27${mu}{ extrm}{m}$. |
