Central air-conditioning variable flow optimization system

Abstract

The invention relates to a central air-conditioning variable flow optimization system which is designed for solving the technical problems that existing similar products are not good in energy efficiency management and energy-saving effect and not scientific in intelligent control and data acquisition. The central air-conditioning variable flow optimization system is characterized in that refrigeration main machines, cooling pumps, freezing pumps and hot water pumps of the system are provided with dynamic controllers, cooling pump dynamic throttling instruments, freezing pump dynamic throttling instruments and hot water pump dynamic throttling instruments respectively, and the refrigeration main machines, the cooling pumps, the freezing pumps and the hot water pumps are connected with computers through signal control cabinets respectively; each branch pipe of a water knockout vessel and each branch pipe of a water collection device are provided with an electric regulating valve and a temperature sensor respectively, the cooling pumps and the freezing pumps are each provided with a flowmeter, a pressure difference transducer and a temperature sensor, a water outlet pipe of each refrigeration main machine is provided with a temperature sensor, each computer conducts analysis on data and controls the corresponding dynamic throttling instrument and the corresponding dynamic controller as well as water inlet and water outlet; storey management devices conduct adjustment on the temperature inside rooms through temperature controllers, and the computers monitor the temperature of the temperature controllers through circuits of fan coils.

Description

technical field [0001] The invention relates to a central air-conditioning energy-saving control system, which is a variable flow optimization system for the central air-conditioning. 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. ...
