Central air-conditioning energy-saving control system

Abstract

The invention relates to a central air-conditioning energy-saving control system which is designed for solving the technical problems that existing similar products are not good in energy efficiency management and energy-saving effect, not scientific in intelligent control and data acquisition and not good in cooling mode and cooling effect of water-cooling draught fans. The energy-saving control system comprises a refrigeration station machine room, a computer and room terminals in pipeline connection with the refrigeration station machine room and the computer, wherein the refrigeration station machine room comprises refrigeration main machines, freezing pumps, cooling pumps, a water collection device, a water knockout vessel, hot water pumps and a frequency conversion control cabinet and a signal control cabinet of the system; the system is characterized in that the computer conducts analysis on data transmitted by flowmeters, differential pressure transducers and temperature sensors, dynamic throttling instruments of the freezing pumps, dynamic throttling instruments of the cooling pumps and dynamic throttling instruments of the hot water pumps and dynamic controllers of the refrigeration main machines are controlled through a frequency converter in the frequency conversion control cabinet, and water outlet of the water knockout vessel is controlled through electric regulating valves. According to the structure of the central air-conditioning energy-saving control system, original cooling towers may be replaced with water curtain frames, and lower water tanks of the water curtain frames are connected with water inlet pipes of the cooling pumps through drainage valves.

Description

technical field [0001] The invention relates to a central air-conditioning energy-saving control system, in particular to a central air-conditioning energy-saving control system. Background technique [0002] The central air-conditioning system is generally composed of a cold and heat source system and an air-conditioning system. It uses the principle of liquid vaporization and refrigeration to provide the required cooling capacity for the air-conditioning system to offset the cooling load of the indoor environment; the heating system provides The heat used to counteract the heat load of the indoor environment. However, the central air-conditioning systems used in some large shopping malls, hotels, hospitals and other places are generally computer room air-conditioning systems, among which water-cooled central air-conditioning systems are widely used. The water-cooled air conditioners are equipped with a cooling tower with a fan cooling water curtain at the air inlet. And r...
