Description

Technical Field

[0001] The invention belongs to the field of fireplace control, and in particular relates to an adaptive energy-saving control system and method for fireplace equipment. Background Art

[0002] At present, the control algorithm used in traditional fireplace equipment is relatively simple, which only adjusts the heating power according to the indoor temperature, without considering other factors that affect comfort and energy saving, such as indoor humidity, air flow rate, radiation temperature, etc. For example, in a high humidity environment, even if the indoor temperature reaches the set value, the human body may still feel uncomfortable, but the electric fireplace cannot adjust according to the humidity change, resulting in the inability to achieve the best energy saving effect while ensuring comfort.

[0003] At the same time, since the control algorithm is relatively simple, the fireplace equipment cannot make accurate and timely adjustments to indoor changes, thus affecting the energy-saving effect.

[0004] Therefore, the above problems need to be solved urgently. Summary of the invention

[0005] Purpose of the invention: In order to overcome the above shortcomings, the purpose of the present invention is to provide an adaptive energy-saving control system and method for fireplace equipment, which quantifies the indoor environment through multiple sensors, calculates the human comfort index based on multiple factors, and adaptively controls the heating mode of the fireplace while ensuring human comfort, thereby achieving energy-saving effects.

The fireplace heating module ensures the normal heating function of the fireplace; by calculating the human comfort index and comparing the threshold to obtain the control instruction, the heating mode of the fireplace can be adaptively controlled to achieve energy-saving effects.

[0007] Furthermore, the sensing module includes a thermistor sensing component, a humidity sensing component, a flow velocity sensing component and a radiation temperature sensing component; the thermistor sensing component, the humidity sensing component, the flow velocity sensing component and the radiation temperature sensing component are arranged in parallel and are all connected to the comfort evaluation module. After the thermistor sensing component, the humidity sensing component, the flow velocity sensing component and the radiation temperature sensing component sense relevant data, they are transmitted to the comfort evaluation module to provide data support for calculation for the comfort evaluation module.

[0008] Furthermore, the thermistor sensor assembly, the humidity sensor assembly, the flow rate sensor assembly and the radiation temperature sensor assembly respectively sense the air temperature t a (℃), relative air humidity f(%), hot air velocity v(m / s) and radiation temperature t r (℃); the human comfort level is based on the air temperature t a (℃), relative air humidity f(%), hot air velocity v(m / s) and radiation temperature t r Thermistor sensor components, humidity sensor components, flow rate sensor components and radiation temperature sensor components integrate several sensors to quantify the indoor environment and collect data from multiple influencing factors.

[0009] Furthermore, the heating mode of the fireplace heating module is divided into three levels: "low-medium-high"; the control instructions of the comfort evaluation module can control the level adjustment of the heating mode of the fireplace heating module.

[0010] Furthermore, the switch control module includes a remote control component and a timing component; the remote control component and the timing component are arranged in parallel and are both connected to the fireplace heating module; the remote control component can control the switch of the fireplace heating module through a mobile phone APP; the timing component can set the running time and automatically turn off the switch of the fireplace heating module after the time is reached. Equipped with a remote mobile phone APP control function, users can remotely control the switch and temperature setting of the fireplace heating module through smart devices such as mobile phones to avoid idling of the equipment when no one is there for a long time; at the same time, it has a timing function, and the switch time of the electric fireplace can be preset, so that it automatically works when the user needs it and automatically turns off when it is not needed, ensuring energy saving.

[0011] Furthermore, the energy module includes an electric energy component and a solar energy component; the electric energy component and the solar energy component are arranged in parallel and together function as a fireplace heating module.

[0021] S202): Calculate the human comfort index K, the formula is as follows:

[0022] K=w1·t′ a +w2·f′+w3·v′+w4·t′ r

Data standardization eliminates the dimensional differences between different features by converting the data into a standard normal distribution, making different indicators comparable; at the same time, by assigning different weights to different parameters, the features that have a greater impact on the human comfort index can be highlighted.

[0024] Furthermore, the calculation formula of the normalized human comfort in S3) is as follows:
