This study is nutrient heating effect to apply the surplus heat recovery in greenhouse using fan coil unit. Especially, this study was carried out to utilize a surplus heat in greenhouse. This fan coil unit system was composed of a water tank, a fan coil unit, a circulating pump and a water-water heat exchanger. As the result, Temperature difference duing to fan coil unit in greenhouse showed that air temperature at experimental greenhouse on fan , comparison greenhouse were 28.3℃, 33.9℃, respectively. heat ratio showed that exchanged energy quantity in fan coil unit was 19,900∼28,880kcal/h, respectively. It was found that difference of nutrient temperature due to surplus heat recovery, water tank temperature were 19.2∼21.5℃ and 16.2∼18.3℃, The temperature variation of nutrient temperature was about 3℃ and higher . Economic analysis of fan coil unit system was increased gross income cost by 804,787 won.
