Numerical Simulation Study on a Localized Environmental Control Device Based on Thermoelectric Cooling Technology

In recent years, thermoelectric cooling technology has gained significant attention for its applications in localized environmental temperature control. This study integrates thermoelectric cooling technology with pet environmental management and proposes a localized environmental control device designed for unattended pet care scenarios. A combined approach of numerical simulation and experimental validation is employed to analyze the effects of operating current, cooling fan speed, inlet airspeed, and external environmental temperature on the thermal environment and energy consumption within the device. The results indicate that operating current has the most significant impact on the thermal environment, with the optimal range determined to be 5A–6A, and a recommended operating current not exceeding 5.5A. Increasing the cooling fan speed effectively reduces both hot- and cold-side temperatures, while an appropriate inlet airspeed helps regulate humidity within the space. Additionally, external environmental temperature exhibits a positive correlation with the internal temperature and humidity. This study provides a technical reference for precise environmental control in pet care and offers essential insights for future system optimization and control strategy development.
