The efficient nutrient solution cooling system consisting of buffer tank, three-way valve, and heat pump et al. was developed for hydroponics of leafy vegetables at high temperatures period. It was designed in such a way that the buffer tank was first cooled to enable precise temperature control of the nutrient solution with small capacity heat pump. Developed system was installed in the NFT hydroponics farm cultivating leafy vegetables and performance evaluation was carried out. For cultivation of Lalique lettuce(Lactuca sativa var.), the temperature of nutrient solution tank, buffer tank, and the root zone, the performance of cooling system, and the environment of greenhouse were analyzed. Also, by measuring the growth and yield of lettuce, the effect of cooling nutrient solution on the growth of lettuce NFT hydroponics was analyzed.
