Intelligent electricity-saving control method for cooling towers in central air-conditioner monitoring system

Abstract

The invention relates to an intelligent electricity-saving control method for cooling towers in a central air-conditioner monitoring system. The intelligent electricity-saving control method is designed to solving the technical problem that in existing central air-conditioner monitoring systems, design of intelligent electricity-saving control methods for cooling towers is in lack of convenience. The intelligent electricity-saving control method is mainly characterized in that a temperature sensor on a pipe arranged between a cooling pump and a cooling water inlet valve of a refrigeration main machine is a cooling water returning temperature sensor; the cooling water returning temperature sensor is connected with temperature sensors at three positions, namely the temperature sensor arranged at the cooling water outlet position of water outlet of the refrigeration main machine, the temperature sensor arranged at the position where a cooling temperature difference of water inlet of the refrigeration main machine is generated and the temperature sensor arranged at the position where a cooling temperature difference of water outlet of the cooling pump is generated; two modes, namely the automatic mode and the intelligent modes, are arranged for the cooling water returning temperature sensor, and thus in the specific operation process of a central air-conditioner, by means of an intelligent algorithm in which the cooling towers are cut away, manual control over the number of the cooling towers is achieved; and by means of a touch screen end of cooling tower equipment, real-time monitoring is conducted, a real-time online sorting algorithm is adopted for operation time of the cooling towers, a time balanced control strategy is guaranteed, and for each time, the cooling tower which runs for the longest time is started and the tooling tower which runs for the shortest time is switched off.

Description

technical field [0001] The invention relates to a central air-conditioning monitoring system, in particular to an intelligent power-saving control method for a cooling tower in the central air-conditioning monitoring system. Background technique [0002] The central air-conditioning system is composed of one or more cold and heat source systems and multiple air-conditioning systems. Generally, the principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air-conditioning system to offset the heat load of the indoor environment; the heating system is The air conditioning system provides the heat needed to counteract the cooling load of the indoor environment. The refrigeration system is a crucial part of the central air-conditioning system, and its type, operation mode, and structural form directly affect the economy, efficiency, and rationality of the central air-conditioning system in operation. In order to achieve the effect o...
