How Does a Compression Refrigeration System Work?
Vapor compression refrigeration systems work through a four-stage cycle: compression (low-pressure vapor becomes high-pressure vapor), condensation (vapor becomes liquid), expansion (pressure drops), and evaporation (liquid absorbs heat and becomes vapor again).
The Different Types of Compressors used in a Refrigeration System
Industrial refrigeration systems use five main compressor types: centrifugal (high-capacity), rotary-vane (compact), rotary-screw (continuous operation), rotary-scroll (quiet/efficient), and reciprocating (scalable). Each requires specific control integration for optimal performance.
Microcontroller vs. PLC: What’s the Difference
While microcontrollers cost less upfront, PLCs are better for industrial automation due to superior environmental tolerance, scalability, programming standards, and greater lifespans.
The Role of PLCs in Manufacturing
A PLC (programmable logic controller) is a ruggedized industrial computer that automates production processes by controlling equipment based on programmed logic and real-time inputs. These industrial control systems serve as the central nervous system that enables a facility to reduce downtime, improve efficiency, and integrate legacy equipment with modern technologies.
A Brief History of Programmable Logic Controllers (PLCs)
PLCs evolved from simple relay replacements in the 1960s to sophisticated industrial computers that enable smart manufacturing, enterprise integration, and IoT connectivity, transforming from basic control devices to intelligent automation hubs.
