Automatic detection and control heating and ventilation system and control method

Abstract

The invention relates to a control method for controlling a heating and ventilation system based on automatic detection, and the method comprises the steps: a central control unit controls a heating device to start heating at an indoor preset temperature; the central control unit controls the temperature and humidity detector to periodically detect the indoor temperature and compares the detection result with the indoor preset temperature to judge whether the actual indoor temperature is qualified or not; the central control unit calculates the difference value between the indoor actual temperature and the preset temperature and adjusts the power of the heating device according to the difference value; according to the method, the actual indoor temperature is detected when the heating duration reaches the preset time, and whether the initial power of the heating device is adjusted or not is judged according to the detection result, so that the situation that the comfort level of indoor personnel is insufficient due to low heating efficiency, and meanwhile system energy consumption is wasted can be effectively avoided; the comfort level of indoor personnel is further improved; and meanwhile, the system energy consumption is low.

Description

technical field [0001] The invention relates to the technical field of heating and ventilation systems, in particular to an automatic detection and control heating and ventilation system and a control method. Background technique [0002] Heating, ventilation and air-conditioning system (HVAC) is almost an indispensable household and commercial appliance in contemporary society. Today, people pay more and more attention to their own quality of life and quality, and it is important for our comfort, health, satisfaction and The HVAC system, which has a great impact on work efficiency and other aspects, has almost been fully integrated into our lives all the time. It is precisely because of its indispensability that the US Department of Energy survey found that the energy consumption of the HVAC system accounts for 40% to 60% of the energy consumption of the entire building. [0003] At the same time, due to the complex nonlinear, time-varying, strong coupling, strong interfer...
