This research introduces the Adaptive Radiative Collector and Emitter (ad-RCE) device, an evolution of the Radiative Collector and Emitter (RCE). The RCE has demonstrated the dual capability of producing hot water using solar collection during the day and cold water below ambient temperature using radiative cooling at night. With the development of new materials, it is now possible to achieve radiative cooling even during daytime. To increase cold production, the ad-RCE integrates daytime radiative cooling (DRC) with nocturnal radiative cooling (NRC) and solar heating (SH) in an active system. The ad-RCE improves the previous RCE as it is designed to dynamically adjust its heat and cold production in response to daily demand. By incorporating a rotating mechanism and novel DRC materials, the ad-RCE allows the transition between radiative cooling and solar heating functions while extending the cooling operation period, representing an innovative approach to harness renewable energy sources for both heating and cooling purposes. This evolution from the RCE to the ad-RCE expands upon the capabilities of the device by increasing the cooling production while reducing the surface requirements of the ad-RCE. This makes the ad-RCE more suitable for energy production in buildings and industrial applications. The paper provides a comprehensive analysis of the ad-RCE, highlighting its benefits and improvements compared to its predecessor, the RCE.
