Problems solved by technology

The working status is basically only a rough comparison of indoor and outdoor temperature and other parameters. The fresh air can work in a vague state, the annual effective working time is short, and the energy saving effect can only reach about 30%.
On the other hand, the current fresh air system fails to locate the specific working state, and at the same time fails to give full play to the maximum energy-saving ratio of the fresh air, and the working efficiency of the fan is low
Moreover, the existing systems on the market have not protected the air conditioner and fresh air for a long time.

Embodiment Construction

[0055] The system provides the following working parameters as the basic parameters of the control logic input:

[0056] Fresh air start temperature value [°C];

[0057] Fresh air fan stop temperature value [°C];

[0058] The maximum working time of fresh air blower [h];

[0059] Air conditioner start refrigeration threshold [°C];

[0060] Air conditioner starting heating temperature limit [°C];

[0061] The minimum working time of the air conditioner (min);

[0062] Air conditioner stop temperature value [°C];

[0063] Indoor associated humidity threshold;

[0064] Outdoor associated humidity threshold;

[0065] High temperature alarm threshold [°C];

[0066] Start the humidity correlation strategy.

[0067] The main control logic of the present invention is explained as follows:

[0068] 1) When the fresh air system is in the working state of "open fresh air, turn off air conditioner":

[0069] 1.1) If this state makes the measured indoor temperature ≤ "fresh air f...

Abstract

The invention aims to overcome the defects of existing equipment control logic, and provides an intelligent fresh air and air conditioning linkage control management method. Fresh air and air conditioning selective intelligent management is realized by making full use of fresh air system and air conditioning linkage management logic, outdoor low-temperature air is maximally delivered into a machine room by indoor and outdoor temperature difference comparison and logic control, indoor hot air is exhausted out of the machine room by an exhaust system, the temperature of an indoor working environment is reduced by high heat ventilation effects, and a normal working environment is effectively provided for indoor devices on the premise of maximally saving energy. By the aid of the control logic, the energy-saving rate of the machine room is increased from 30% to 60%, more than half of energy can be annually saved for the machine room when each device is used in an online manner, long-time operation of an air conditioner is effectively reduced, and the operating life of the air conditioner is prolonged.

Description

technical field [0001] The invention belongs to a control method, in particular to an intelligent fresh air air conditioner control and management method. Background technique [0002] With the rapid development of the world's high-speed railways and mobile communication signal computer rooms, there are more and more smart devices in the computer room, and the heat generated by the computer room has increased geometrically. At the same time, the requirements for the working environment of all smart devices are getting higher and higher. In order to ensure the normal operation of the communication signal equipment in the computer room, make the environment in the computer room meet the requirements of standard working conditions, and at the same time maximize the use of the temperature difference between the indoor and outdoor environments of the computer room, reduce the working time of the air conditioner in the computer room, and achieve the purpose of maximizing energy sav...
