A temperature control apparatus for water-curtain cultivation is provided to maintain the inner temperature of a greenhouse by using a small quantity of water of about 3tons instead of underground water. A temperature control apparatus(100) for water-curtain cultivation comprises: recovery water-receivers(120) which are placed near the ground surface on which a greenhouse is installed and recover the water dropping from a water curtain formed at the outer surface of the greenhouse; a water reflux pipe(122) which is connected to the water receivers, and through which the recovered water is passed; a recovery water tank(130) in which the passed water is stored, and which sinks foreign substances or insects to perform purification; a water supply pump(140) which supplies the purified water through a pipe installed at the side of the recovery water tank; a water heater/cooler(150) including a heater/cooler controller(154) which measures the temperature of the supplied water by a temperature sensor(152) and performs a heating function to maintain a fixed temperature; a water supply pipe(160) which is connected to a water output part of the water heater/cooler and extended to the top of the greenhouse, and through which the water heated to a fixed temperature is passed; and a water supply nozzle(164) which is installed at the end of the water supply pipe and at the top of the outer surface of the greenhouse and allows the water passed through the water supply pipe to drop to the outer surface of the greenhouse through a plurality of spray holes, thereby forming a water curtain and keeping the inside of the greenhouse warm by heat transfer. |
