A Review of IOT Based Evaporation Coolers

Water tanks are one of the main components of an evaporation cooling system. The water levels in these tanks needs to be regulated to obtain their optimal performance. This paper reviews the application of Internet of Things (IOT) in hot water tanks with the objective of making the system more cost efficient. In the absence of a monitoring system for a water tank, there is a high possibility of water overflow. The smart water tank solutions provide automatic monitoring of water available in the tank and simultaneously provides the user with real time updates using a host of incorporated sensors. The IOT based system enables the water pump to start automatically when the water level falls below the threshold and switches it off at the instant the tank is full. The cooler’s new technological shift with the use of IOT has improved their performance over conventional coolers’. Furthermore, IoT has enabled incorporation of various other functionalities within the cooler to address other real time issues in cooling. Several scientific techniques that have been employed to improve the performance of the coolers have been reviewed in this work.
