Unmanned-operation central air conditioner intelligent system and control method thereof

Abstract

The invention discloses an unmanned-operation central air conditioner intelligent system and a control method thereof. The unmanned-operation central air conditioner intelligent system comprises a terminal billing system, a cloud platform and a machine room control system. The terminal billing system comprises a wireless receiving and transmitting module, a wireless intelligent controller and a wireless base station. A control box of a fan coiled tube is connected with the wireless receiving and transmitting module, the wireless receiving and transmitting module is in wireless connection withthe wireless intelligent controller, and the wireless intelligent controller is in wireless connection with the wireless base station. The wireless intelligent controller comprises an electric two-wayvalve opening-closing module for controlling an electric two-way valve to be opened and closed, a fan starting-closing module for controlling the fan to be started and stopped and an air speed control module for adjusting the air outlet speed of the fan. The cloud platform is in wireless connection with the wireless base station. The machine room control system comprises a water pump set, an airconditioner unit, an instrument sensor and a PLC, and the fan coiled tube is connected with the air conditioner unit through a pipeline. According to the unmanned-operation central air conditioner intelligent system and the control method thereof, a machine room control system is automatically adjusted according to the terminal load rate, so that closed-loop adjustment is achieved, energy consumption is greatly saved, and the user using comfort is improved.

Description

technical field [0001] The invention relates to the field of artificial intelligence and the field of central air conditioning. More specifically, the present invention relates to an unmanned central air-conditioning intelligent system and a control method thereof. Background technique [0002] With the rapid development of society and the continuous improvement of human living standards, central air-conditioning has been more and more widely used in commercial, hotel, office buildings, government agencies, residential quarters, high-end apartments, schools, In hospitals and other fields, while central air-conditioning solves the problem of comfort, its energy consumption has also attracted more and more attention. The energy consumption of building air-conditioning accounts for 15-20% of the energy consumption of the whole society. [0003] The central air-conditioning smart energy system generally includes two parts: terminal billing and computer room control. The termin...

Problems solved by technology

Although the area-based charging method in the traditional billing method is simple, convenient, and low-cost, it cannot meet the differentiated needs of users for energy, and cannot mobilize users' behaviors to save energy. Users have no energy-saving awareness and behavior, resulting in a large waste of energy; The meter charging method requires accurate measurement of each terminal device, and each terminal needs to be equipped with a flowmeter and two thermometers, which not only requires large equipment investment, high cost, and difficult maintenance, but also has a short service life of the heat meter; use WiFi The method of connecting the thermostat requires the user to install broadband and add a WiFi router, which increases user costs and increases the difficulty of user use and maintenance; traditional billing methods require operators to regularly query and print user fee details, and cost a lot of money. Spend time and energy communicating and coordinating with users to complete the entire charging process

[0005] The overall degree of automation in the control of the computer room is not high, and the working conditions cannot be adjusted in real time according to the load at the end, resulting in waste of energy or poor use of users. Most of them require operation and maintenance personnel to be stationed for a long time and monitor in real time, which greatly increases Operation and maintenance cost
