SIM-ED Thermal Power Distribution Simulator Refrigeration Training Equipment Technical Didactic Equipment

Simulator mod. SIM-ED aims: it simulates the operation of a set of power distribution systems for residential buildings heating or cooling.
TRAINING PROGRAM
• Analyzing the operation of an outdoor reset controller
• Studying the emission curve of a heating element, the characteristic curve of a three-way mixing valve and the emission of a heating element versus the position of the valve shutter
• Open-loop and closed-loop control
• Analyzing the operation of a controller for radiant systems with limit function
• Correlation between room parameters and water delivery temperature for cooling systems with radiant panels
• Studying the performance of a fan coil
• Proportional and ON/OFF control
• Analyzing the operation of a controller for zone distribution
system with continuously controlled 2-way valve
• Analyzing the operation of a room thermostat
