TRAINING OBJECTIVES
With this equipment, students can perform several experiments in the following knowledge areas:
• Heat transfer and thermal insulation.
• Refrigeration cycles of vapor compression.
• Refrigerant fluids.
• Calculation of thermal loads.
• Psychrometric processes (low temperature).
• Cold stores and industrial refrigeration.
• Automatic control and instrumentation.
TECHNICAL DESCRIPTION
The test bench consists of: a refrigeration chamber with a forced flow evaporator fed by thermostatic expansion valve, a 250W condenser unit and a transparent heated access panel.
The refrigerator circuit is equipped with:
• Flow display.
• Heat exchanger with solenoid valve.
• Electric defrost system.
• Control system via PLC and programmable timing functions.
• Drier filter and liquid storage tank.
The use of separate controls allows the simulation of different malfunctions.
The anti water hammer protection in the compressor system ensures reliable operation under extreme conditions.
The steam overheated can be regulated by the thermostat valve settings.
COLD ROOM
With this system, students can study and analyze the phenomena of the industrial refrigeration.
This system integrates all the main components that can be found in a cold room facility.
This system is composed of modular components and can reach freezing temperatures as low as -30°C.
