Electric and automatic air distributor for ships

Abstract

The invention relates to an electric and automatic air distributor for ships. The electric and automatic air distributor comprises a box body. An air inlet device, an adjusting device and an air outlet device are arranged inside the box body. The air inlet device comprises an air inlet and an air inlet flow rectifier, wherein the air inlet is formed in the box body, and the air inlet flow rectifier is arranged on the inner side of the box body and connected with the air inlet. The air inlet flow rectifier is cylindrical. Ventilation holes are evenly distributed in the side wall of the air inlet flow rectifier. The adjusting device comprises an actuator and a valve plate. The valve plate is connected to the output end of the actuator and is in a left-right moving state inside the air inlet flow rectifier. The air outlet device comprises an air outlet and an air diffuser, wherein the air outlet and the air diffuser are arranged at the bottom of the box body, the air diffuser is installed at the air outlet, and five air outlet faces of the air diffuser are evenly provided with evenly-distributed ventilation holes. The actuator integrates an air quantity sensor and a temperature sensor and is connected with a computer control unit. The valve plate moves in the air inlet flow rectifier to adjust the effective ventilation length of the cylindrical flow rectifier so as to control the air inlet quantity and pressure, so that the temperature is adjusted, and the automatic adjustment function is achieved.

Description

technical field [0001] The invention relates to a terminal device of a ventilation system, in particular to an electric automatic air distributor used in a ship air-conditioning variable air volume system. Background technique [0002] In order to save energy, the existing air-conditioning and ventilation systems of ships generally adopt the design of variable air volume system. The air-conditioning air supply end device is a single-duct air distributor. This type of air distributor is mainly composed of VAV variable air volume terminal and air distributor box; weight It is heavy and occupies a large space, which brings inconvenience to the installation and operation; if only the air distributor is used, its function is relatively single, and some cabins will be overcooled or overheated, and the air volume cannot be automatically adjusted according to the change of the cabin load; the traditional The sound absorption coefficient of the rubber and plastic insulation material ...
