## 6 IoT-Enabled Systems  
A significant advancement in outdoor cooling is represented by smart and Internet of Things (IoT)-enabled outdoor air conditioning systems, as shown in Figure 6. These systems have various state-of-the-art features and technologies that improve their functionality, energy efficiency, and user comfort [57]. Monitoring in real time via sensors is one of the primary components of these systems, which utilise a network of sensors that collect data on various environmental properties. These sensors can measure various variables, including temperature, humidity, air quality, and occupancy. Real-time data obtained by these sensors provide the foundation for dynamic control and optimisation [58]. Data management is conducted using advanced data analytics methods, and sensor data are processed and evaluated. These strategies may identify patterns, trends, and anomalies in the data. For instance, they may detect changes in the outside temperature, which may result in adjustments to the cooling system's settings [59]. Innovative outdoor air conditioning systems can dynamically adjust their operation depending on the information gained through data analysis. For instance, the system may adjust when exterior temperatures increase significantly by boosting its cooling capability to maintain the ideal inside temperature. Alternatively, the system may operate more efficiently to save energy during periods of lower demand [60]. Additionally, these systems prioritise energy efficiency, which reduces running expenses and has a reduced effect on the environment. They may adjust the functioning of components such as pumps, fans, and compressors according to the cooling requirement, decreasing energy waste [61]. Moreover, smart systems are developed to provide the highest possible comfort for users. They can consider user preferences and adjust elements such as temperature and ventilation to create a pleasant atmosphere. They may also preserve air quality by monitoring and adjusting ventilation rates [62]. Frequently, IoT-enabled outdoor air conditioning systems can be remotely monitored and managed. Facility managers or homeowners can remotely inspect and modify system settings using a smartphone application or web interface. According to [PERSON] et al. [63], this feature facilitates proactive system maintenance and increases usability. These systems are also capable of self-diagnosing issues and sending maintenance reminders. The method can detect component failures in advance and notify maintenance personnel, decreasing downtime and preventing costly breakdowns. Incorporating smart and Internet of Things (IoT)-enabled technology into outdoor air conditioning systems represents a significant leap in the industry, providing various cutting-edge features that improve functionality, energy efficiency, and user comfort. A network of sensors continually monitors environmental

These sensor data are processed and analysed using sophisticated data analytics methods to find patterns, trends, and anomalies that might influence system modifications [64]. For example, when the system senses a fast increase in external temperatures, it may change its cooling capacity to maintain ideal internal temperatures. These intelligent systems emphasise energy efficiency by adapting components such as pumps, fans, and compressors to current cooling needs, minimising energy waste and saving operating costs [65]. The devices may react to the user's preferences and modify temperature and ventilation rates to produce a pleasant atmosphere [66]. Moreover, IoT-enabled systems provide remote monitoring and management through smartphone applications or web interfaces, enabling proactive system maintenance [67].
