This paper proposes a novel approach to home cooling systems that offers significant advantages, including low power consumption, zero emissions of harmful gases, and health benefits. The core principle of the system is based on free cooling, which occurs when the external ambient air entropy is lower than the indoor air enthalpy. The system efficiently transfers cool external air directly into building rooms. Historically, the efficiency of external cool air systems has been limited by external air velocity, decreasing their popularity. This paper introduces a new model that enhances cooling efficiency using air collector systems and rotary fan systems. The proposed air conditioning systems can deliver 100% fresh air by utilizing outside air, making them suitable for hospitals and densely occupied places such as theaters. This system is effective only when the outdoor temperature is lower than the indoor temperature.
