Heating and decentralized air-conditioning system for teaching or office building and control method

Abstract

The invention discloses a heating and decentralized air-conditioning system for a teaching or office building and a control method; in the system, an operation terminal is connected with a server through a first network; the server is connected with a regional manager group through a second network; all regional managers are connected with all on-site controllers in corresponding on-site controller groups through data communication lines; all the on-site controllers are arranged in all the rooms of the teaching or office building; all the on-site controllers are connected with radiators in the rooms; radiator electric two-way valves are arranged on hot water inlet pipes of the radiators; the method comprises the steps that: centralized control is realized by networking, so that heat supply, room temperature as well as heating and decentralized air-conditioning of all the rooms in the teaching or office building are controlled in real time, the heating or refrigeration speed is high, the automation of heating and decentralized air-conditioning of the teaching or office building can be effectively improved, the purpose of energy saving is achieved, and heating or refrigeration are truly realized.

Description

technical field [0001] The invention relates to the technical field of energy-saving heating and distributed air conditioning for large buildings, in particular to a heating and distributed air conditioning system and a control method for teaching or office buildings. Background technique [0002] Heating energy consumption is the main energy consumption of school teaching buildings or office buildings in heating areas in winter. At present, the heating of teaching buildings or office buildings mainly uses indoor radiators, also known as radiators, to maintain a certain indoor temperature. Time-sharing control system or installation of temperature control valves and other measures to achieve energy saving. Time-sharing control refers to reducing the building heating flow at night and on holidays, and increasing the building heating flow in advance before going to work or going to class in the morning. There is still room for further energy saving, which is mainly reflected i...

AI Technical Summary

Problems solved by technology

[0003] 1) Teaching buildings or office buildings are affected by curriculum arrangements or flexible working hours. Although the utilization rate of some classrooms, teaching laboratories, scientific research laboratories or offices is not high, especially during the winter vacation, the utilization rate of various rooms is lower, but sometimes In order to meet the needs of some rooms, the whole building must be heated during the day, resulting in a lot of waste of heat energy;

[0004] 2) Radiators are generally used for heating indoors in teaching buildings or office buildings, and the heating lag time is long. It is necessary to increase the heat flow supply of the building several hours in advance to ensure the required indoor temperature during cla...
