Control method of tower type heat absorber with air curtain screen

Abstract

The invention discloses a control method of a tower-type heat absorber with an air curtain screen. The tower-type heat absorber with the air curtain screen comprises a heat absorption device, an upper air curtain structure and a lower air curtain structure, wherein the upper air curtain structure is arranged at the upper part of the heat absorption device and blows air downwards; the lower air curtain structure is arranged at the lower part of the heat absorption device and blows air upwards; and outlet air of the upper air curtain structure and outlet air of the lower air curtain structure form the air curtain screen. The control method comprises the steps that air flow information of the environment where the heat absorption device is located is obtained; and the upper air curtain structure and the lower air curtain structure are started according to the air flow information to form the air curtain screen. Due to the fact that the upper air curtain structure and the lower air curtain structure are controlled to be started to form the air curtain screen, the air curtain screen blocks external high-flow-speed air from traversing the surface of the heat absorption device, a low-convection environment or a windless environment can be formed on the surface of the heat absorption device, convection heat exchange is greatly reduced, and convection heat loss of the heat absorption device is greatly reduced. 本发明公开了一种带风幕屏的塔式吸热器的控制方法，带风幕屏的塔式吸热器包括：吸热装置；上风幕结构，设置在所述吸热装置的上部，并向下出风；下风幕结构，设置在所述吸热装置的下部，并向上出风；其中，所述上风幕结构的出风和所述下风幕结构的出风形成风幕屏；所述控制方法包括：获取所述吸热装置所处环境的风流信息；根据所述风流信息，启动所述上风幕结构和所述下风幕结构以形成风幕屏。由于通过控制上风幕结构和下风幕结构启动形成风幕屏，风幕屏阻挡住外来高流速空气横掠吸热装置的表面，可在吸热装置表面形成低对流环境或者无风环境，大大降低了对流换热，从而大幅降低吸热装置的对流热损失。
