TB230329S07 Refrigeration Simulator System Vocational Training Equipment Equipment Equipment Refrigeration Trainer Equipment

Description:

• This educational simulator should be designed for training in the sector of computer-aided control of industrial systems and it simulates the operation of an industrial refrigeration system with two cold rooms: one for frozen products (L.T.: low temperature) and the other for fresh vegetable products (M.T.: medium temperature)
• It should enable to check the system behaviour and the importance of the involved parameters, once fixed the set-point values of reference variables

Experimental Capabilities:

• Studying the pressure-enthalpy diagram of a refrigerant
• Studying on the psychrometric chart the air transformations at the evaporator of a cold room
• Heat balances on refrigerant side and on air side
• Studying the heat losses of a cold room
• Analyzing the behaviour of a refrigeration system with a unique compressor/condenser set and double level of evaporation pressure
• How the difference between room temperature and evaporation temperature affects the relative humidity of a cold room for fresh food
• Analyzing the operation of an electronic expansion valve
• Analyzing the operation of an evaporation pressure regulator
• Proportional and ON/OFF control
• Programming and testing ON/OFF or PI control logics
