Abstract
It is a great problem to low down the temperature in greenhouse in the summer in the southern area of china.The ecological greenhouse was designed to solve the problem,which consisted of plastic-covered shed,tropical trees and tall deciduous trees around the shed,spraying equipment at the top of shed,heating exchanger and draught fan inside the shed.The computer was introduced to control the temperature by regulating the equipment in summer and winter.The result showed that the temperature was 4.5℃ degree lower,the humidity was 7% higher than that outside in the summer,the temperature was raised by heating from the geothermal energy exchanger in the winter In this way the greenhouse could be used for planting both in summer and winter.
