Lead-acid batteries utilised in electrical substations release hydrogen and oxygen when these are charged. These gases could be dangerous and cause a risk of fire if they are not properly ventilated. Therefore, this research seeks to design and implement a network control panel for heating, ventilation, and air-conditioning systems (HVACS). This is done using a specific range of controllers, which have more than thirty loops of proportional, integral and derivative (PID) control to achieve a cost-effective design. It performs the required function of extracting hydrogen, oxygen, and maintaining the desired temperature of the battery storage room within the recommended limits (i.e. 25°C ±1°C tolerance) without compromising quality as set out in the user requirement specification in Appendix-A. The system control panel allows the user to access control parameters such as changing temperature set-points, fan-speed, sensor database amongst others. The hardware is configured to detect extreme hydrogen and oxygen gas content in the battery room and ensure that the HVACS extract the gas content to the outside environment. The results of the system show that the network control panel effectively operates as per the recommended system requirements. Therefore, the effective operation of the HVACS ensures sufficient gas ventilation, thus mitigating the risk of fire in a typical battery storage room. Furthermore, the effective operation of HVACS enhances battery lifespan because of regulated operating temperature, which is conducive to minimise the effect of sulfation in lead acid Batteries (LABs).

Therefore, this research seeks to design and implement a network control panel for heating, ventilation, and air conditioning system (HVACS).

It performs the required function of extracting hydrogen and oxygen, maintaining the desired temperature of the battery storage room within recommended limits (i.e., 25 ± 1 °C tolerance) without compromising quality, as set out in the user requirement specification. The system control panel allows the user to access control parameters such as changing temperature set-points, fan-speed, sensor database, etc. It does this automatically and allows no human interface after all necessary settings and installation are completed. The hardware is configured to detect extreme hydrogen and oxygen gas content in the battery room and to ensure that the HVACS extracts the gas content to the outside environment. The system’s results show that the network control panel operates effectively as per the recommended system requirements. Therefore, the effective operation of the HVACS ensures sufficient gas ventilation, thus mitigating the risk of fire in a typical battery storage room. Furthermore, this also enhances battery lifespan because of regulated operating temperature, which is conducive to minimise the effect of sulfation in lead–acid batteries (LAB). The extraction of toxic gases, regulation of temperature, ensuring suitable humidity in UPS battery room is important as it provides longer operational service of equipment, thus reducing frequent maintenance in these rooms. This benefits the electricity supply industry and helps in saving for unplanned maintenance costs.

The air quality from closed spaces is very important for people or for technological processes. The heating, ventilation and air conditioning installations ensure the maintenance of the air parameters in the rooms served within pre-established limits, throughout the year, regardless of the variation of meteorological factors, the degree of occupancy of the rooms or the development of production processes. The paper presents an automatic ventilation, heating and air conditioning system made on a small scale. Climatic parameters can be monitored and controlled in two ways: in local mode and also in remote mode. In local mode, the control of the installation is done with a Mega 2560 development system made around the Atmega 2560 microcontroller, which processes the information received from the DHT22 temperature and humidity sensor. Information about parameters and system status is displayed on the local screen. The WeMos D1 R2 WiFi development system based on an ESP8266 wireless microcontroller with Wi-Fi 802.11 compatible with the IDE-Arduino development environment was used for the remote control. All information is transmitted wirelessly to an online platform, called Cayene that allows their storage and control. The platform referred to offers a number of graphical features that do not involve costs for users. The system can be used both for educational purposes for engineering students, but can be adapted for real practical applications.
