The patent application (Publication Number: US20240019192A1) describes a cold storage system with innovative features. The first claim outlines a cold storage unit with a compressor, fan, heater, and control apparatus that work together to maintain a set temperature in the storage chamber. The control apparatus activates the heater when specific conditions related to temperature and compressor operation are met, ensuring optimal storage conditions.

Moving on to the second claim, the cold storage system includes a sensor that detects the temperature in the storage chamber. The control apparatus operates the heater based on the set temperature, compressor status, and the temperature detected by the sensor. This additional feature enhances the precision and efficiency of temperature control within the storage unit. Furthermore, the patent also introduces a unique sliding door design in the third claim, with two sliding doors that allow for improved access and insulation. Additionally, the inclusion of a drain pan heater in the fourth claim showcases a comprehensive approach to managing water generated during defrost operations. Overall, the patent presents a sophisticated cold storage solution with multiple innovative features aimed at optimizing temperature control and operational efficiency.
