AI-Driven Frost Recovery: Maintaining a Constant 20°C Office Without Extra Power
At the Yangmei Logistics Center operated by Success Capital Company Limited Taiwan Branch, GreenValue has implemented a real-time defrost management system powered by AI image recognition. When the camera detects that 70% of the evaporator fin surface is covered in frost, the system automatically triggers the defrost cycle, ensuring optimal system performance and minimal energy waste.
A distinctive feature of this facility is the reuse of residual thermal energy from the brine defrosting process. The chilled brine is directed through insulated piping into the HVAC system, where it is integrated into the cooling loop to help regulate indoor temperatures. As a result, the second-floor office area—spanning approximately 1,300 square meters—can be consistently maintained at a comfortable ambient temperature of around 20°C.
This design achieves monthly electricity savings of nearly 80%, balancing energy efficiency with indoor comfort—earning the site the nickname, “a warehouse that breathes.
From Pharmaceutical Cold Chain to Smart Food Logistics
This innovation originates from GreenValue’s extensive experience in cold chain infrastructure engineering and temperature-controlled logistics. CEO Yu-Feng Hsu, having grown up in the HVAC industry, has led the company in delivering numerous high-compliance projects for the biopharmaceutical logistics sector, including ultra-low temperature vaccine storage facilities.
In 2021, amid the urgent national response to the COVID-19 pandemic, GreenValue was tasked with designing and constructing a GMP-compliant cold storage warehouse exceeding 825 square meters, under a compressed timeline of just three months—a build process that typically spans over six months under normal conditions. Despite the scale and urgency, the facility was successfully delivered on time, integrating airtight insulated panels, redundant refrigeration systems, and high-precision temperature control solutions to ensure full compliance with Good Distribution Practice (GDP) standards for pharmaceuticals.
Between 2021 and 2024, GreenValue continued to support the deployment of several vaccine storage centers across Taiwan. Collectively, these facilities safeguarded the storage and handling of over 40 million vaccine doses, reinforcing Taiwan’s medical cold chain resilience during critical public health periods.
Today, this proven expertise is being extended beyond pharmaceuticals into smart cold c‵hain applications for the food industry, enabling real-time monitoring, predictive maintenance, and energy-optimized refrigeration strategies across multi-temperature storage and logistics environments.
AI-Guided Defrosting Logic for Dynamic Storage Environments
Unlike pharmaceutical-grade storage facilities that require strict temperature uniformity, food logistics warehouses are subject to fluctuating thermal loads due to seasonal demand and high-frequency access during promotional periods. Frequent door openings accelerate frost accumulation on evaporator surfaces, increasing the need for defrost cycles. However, conventional fixed-interval defrosting strategies (e.g., every 4 hours) often lead to unnecessary energy consumption and suboptimal system performance.
To mitigate these inefficiencies, GreenValue deployed a brine-based defrosting system, which minimizes dependence on electric heating. The system captures residual cooling from the defrost process and channels the chilled brine back into the building’s HVAC loop—forming a closed-loop thermal recovery cycle that significantly reduces both compressor load and carbon emissions.
During the prototyping phase, GreenValue engineers began with basic camera rigs to manually monitor frost levels. This evolved into a full-scale system using -20°C-rated thermal cameras and a proprietary AI-driven visual recognition module capable of detecting frost coverage on evaporator fins in real time.
Once the system identifies a frost threshold of 70% surface coverage, it autonomously triggers the defrost cycle. Unlike traditional fixed-timer methods, this solution employs real-time data inputs to adjust both the defrost duration and brine energy recovery parameters dynamically.
This demand-responsive control strategy not only avoids premature or delayed defrosting but also aligns system behavior with actual environmental conditions—improving operational efficiency, extending equipment life, and lowering overall energy intensity.
