Building heating and ventilation control system

Abstract

The invention discloses a building heating and ventilation control system, comprising: a microprocessor which is in signal connection with a program memory and a working memory to form a microcomputer, an A / D converter which is electrically connected with a microprocessor and a multi-input controller and converts the simulation signal sent by the multi-input controller into the digital signal and sends the digital signal to the microprocessor, and a D / A converter which is electrically connected to the microprocessor and a multi-output controller and converts the digital quantity of the microprocessor into the analog quantity and sends the analog quantity to the multi-input controller. The system detects the temperature and the humidity of the building through a temperature and humidity sensor and performs real-time data connection with related data of heating and ventilation execution devices in the program memory, the operation of the execution device can be adjusted at any time to achieve the best heating and ventilation status, and at the same time, the manager can use the smart phone for intuitively understanding the heating and ventilation execution devices in real-time state, which can quickly and accurately determine whether the state is in the hydraulic equilibrium and thermal equilibrium.

Description

technical field [0001] The invention relates to the technical field of building heating and ventilation, in particular to a building heating and ventilation control system. Background technique [0002] Building HVAC systems are more and more widely used in some large buildings or building groups. During use, some areas cannot reach the expected temperature and humidity, resulting in a great waste of energy. As for the building HVAC system, the quality of its control is directly related to the environmental quality of the entire controlled space and the working quality of the building HVAC system. In the prior art, the HVAC system is usually monitored through a large number of operating parameters of the HVAC system, and the operation and control status of the HVAC system are judged by analyzing the data. This kind of interactive interface cannot intuitively reflect the operation effect of each equipment of the HVAC system, and users cannot observe real-time data, which ca...
