Base module for refrigeration and air-conditioning

Tabletop unit mounted on an aluminium structure including:

• Hermetic compressor
• Variable speed fan air condenser
• Sight glass, dehydrator filter, liquid separator
• High and low pressure gauges
• 2 temperature sensors to be applied onto different points of the hydraulic circuit
• Electronic flowmeter
• High and low pressure transducers
• Voltage, current and power transducers
• Double pressure switch
• Operating valve for filling and bleeding the refrigerant
• Cocks and flexible pipes with valve for the connection with the experimental module
• Solenoid valves for inserting faults
• Switchboard including:
• power cord
• thermomagnetic
• earth leakage control button
• emergency button
• start button with pilot lamp
• Control unit with the following characteristics:
• Autonomous operation or Remote Control (via PC, not included in the equipment)
• USB interface for connection with PC
• Liquid-Crystal Display for showing the outputs, the inserted faults, the selected experimental module, the time trend of input signals such as temperature, pressure, relative humidity, volume flow rate, air speed, voltage, current, electric power
• interface board that transforms the module or the PC into an industrial equipment for controlling and processing analog and digital inputs and outputs such as the state of solenoid valves, of compressor, of fan, of heating, cooling, humidification and dehumidification, etc… devices
• numerical keypad for inserting faults (8 at the most, after the operating mode has been enabled), selecting the experimental module, etc…
