Definition: Certification from the Carbon Trust verifying an organization’s carbon footprint measurement, reduction targets, and progress toward carbon neutrality. Provides independent verification of environmental claims. Why It Matters: Demonstrates credible environmental commitment. Increasingly required by major corporate customers with sustainability targets. Differentiator in competitive tender situations. Supports ESG (Environmental, Social, Governance) reporting. Certification Types:– Carbon Footprint Standard (measurement)– Carbon Neutral…
Carnot Cycle
A theoretical thermodynamic cycle that represents the most efficient possible refrigeration cycle. Real refrigeration systems approach but never achieve Carnot efficiency.
Centrifugal Compressor
High-speed rotating impeller, used in very large cold storage facilities (500+ kW).
Advantages:: Very high capacity, efficient at large scale
Certification vs. Compliance
Important distinction often confused in cold chain.
Chain of Custody
Documented record of product possession and handling from manufacture through distribution to end user. Critical for high-value pharmaceuticals and controlled substances.
Chilled (Refrigerated)
Temperature range typically between 0°C and +8°C (most commonly +2°C to +5°C), used for products that must remain cold but not frozen.
Cleaning and Sanitation
Two-step process for food contact surfaces and equipment. Cleaning removes visible soil; sanitation reduces microorganisms to safe levels.
Cloud-Based Monitoring
Temperature monitoring system where data from sensors is transmitted to cloud servers via cellular/internet connection, accessible from any device with internet access.
Coefficient of Performance (COP)
A measure of refrigeration system efficiency, calculated as the ratio of cooling capacity (output) to energy consumed (input). Higher COP indicates better efficiency.
Cold Chain
Temperature-controlled supply chain that maintains product quality and safety from production through transport and storage to end consumer. Unbroken “chain” of refrigeration.
