Electrical refrigeration and Waster water treatment

Introducion:

• Industrial Refrigeration Training Unit is perfect for educating HVAC/R students on the principles of commercial and industrial refrigeration systems.
• Add it to your curriculum and give future technicians an opportunity to learn from hands-on experience.

Training Program:

• Introduction to the HVACR basic fundamentals and terminology, and the applied physics concepts that are utilized in HVACR systems
• Instruction aligns with ANSI/ACCA Quality Installation and ANSI/ ACCA/ ASHRAE Standard 180 Quality Maintenance protocols
• Components and operational differences of a heat pump vs. a straight air conditioning system, troubleshooting, and solutions
• Thorough examination of the refrigeration cycle as it is applied to both air conditioning and refrigeration purposes, and presents a practical and systematic method to diagnose problems in the refrigeration cycle
• Presentations describe the application of common accessories found in a system, piping arrangements, sizing considerations and system operation.
• How to identify when and where there is a leak, Leak detection methods, Reasons for system evacuation, Operation of a Vacuum Pump, Operation of a Micron Gauge, Importance of the correct charge, and Methods used to check a charge
• Some system troubleshooting, work on the 9 most common system problems
• Apply TROT (The Rule Of Thumb)
• Commercial Cooling Tower Systems, with a basic introduction as to the layout of the various components utilized in large and small commercial facilities

Technical Specification:

• Electrical Requirements: 240VAC; 60Hz; 30A
• Uses R422B Refrigerant
• Compressor: Semi-hermetic type with 2 HP capacity
• Overall Size: 95” L x 25.25” W x 80” H
• Water Tower: 115VAC; 60Hz; single phase; 60,000 BTU/hour (This is an optional add-on)
• Utility Requirements: city water, drain, and means to vent water vapor
