CIRCULATION TYPE WATER CURTAIN SYSTEM AND CONTROL METHOD THEREOF

摘要

A circulation-type heat-retaining water curtain system and a controlling method thereof are provided to be operated even with minimum amount of water and to rapidly alert a manager to its malfunction. An intake pump(22) takes underground water and supplies it to a water feed tank(21). A water supply device supplies and sprays the underground water of the water feed tank to the surface of a greenhouse. A collection device collects the sprayed underground water and transfers it to the water feed tank. A heater(30) heats the underground water on demand. The water supply device consists of a water piping(31,32,33), a spray hose(34) and a water feed pump(35). The heater represents a boiler to heat the underground water supplied through the water piping. The circulation-type heat-retaining water curtain system additionally includes a collection temperature sensor, a release valve(48) and a collection pump(46) or a controller.
