Air Conditioner Condensing Unit Cooling System

Abstract

A cooling solution designed for air conditioners (ACs) that automatically and efficiently sprays water onto the condensing coils of the AC to dissipate heat and to enhance AC performance. The system includes a control box with a processor and a temperature sensor that continuously monitors outdoor or ambient temperature. The processor compares the real-time ambient temperature data with a pre-set threshold temperature, and upon detecting higher ambient temperatures, activates the misting process. An integrated water solenoid valve regulates water supply from a water source to a misting nozzle, which creates a controlled mist to cool the condensing unit. The control box is equipped with an internal memory to store threshold temperature and control algorithms, and an LED that serves as a status indicator.
