Basis on the present conditions and the development direction of the cooling system for greenhouse in our country, deeply analyzing a few cooling methods that wide used at present. In light of the enthalpy and wet peculiarity of atmosphere and the principle of cooling by evaporate, putting up a new cooling system for greenhouse in the high temperature and high wet distinct in summer - liquid dehumidifying and cooling system .This cooling system is a reform basis on the wet pad-breezing machine system, its c...
