Abstract

The invention discloses a control system for operation of a dry-wet combined cooling tower. The control system involves a central controller, wherein the central controller is connected with a plurality of dry cooling tower controllers and a plurality of wet cooling tower controllers, and the dry cooling tower controllers and the wet cooling tower controllers are connected with a valve control system, a water outlet temperature system, a fan frequency control system and a signal transmission control system. The control system has the following advantage that the dry-wet combined cooling tower is accurately controlled to reduce the loss of circulating water to the minimum.

Description

technical field [0001] The invention relates to the field of circulating cooling tower water systems, in particular to an operation control method of a dry-wet combined cooling tower system. Background technique [0002] In the chemical industry, petroleum, electric power and building air-conditioning systems, it is often necessary to cool the hot process medium. The circulating water system uses the temperature of the water to rise after passing through the heat exchanger, and then the water temperature is lowered by the cooling equipment, and the water is delivered to the user by the pump, so as to carry out continuous recycling. Among them, the cooling equipment is divided into dry cooling tower and wet cooling tower due to the different operation process. A dry cooling tower passes water through tubes with fins, the water transfers heat to the fins, and the fins contact the air to transfer heat to the atmosphere. The wet cooling tower uses the direct contact between ai...
