The trainer is consist of a mobile, floor standing process unit, frame are all made of Anodize aluminum profile, aluminum anodize etching mimic diagram with elaborate Process diagram & electrical circuit. All components are mounted on the trainer. The Trainer is able for student to investigate the theoretical performance of refrigeration System along with the various treatments utilized in the air flow distribution cycle. Including heating, cooling, humidification, and recirculation and mixing.
Air flow duct and circuit made of light weight epoxy coated G.I. duct. With eight inter-changeable end plates, provides two different, i.e. round and rectangular ducts. Also provides elbows and flanges coupler. With size orifices all combined to provide an enormous variety of operating conditions. For students to investigate the pressure drop, velocity pressure and static pressure.
Refrigeration circuit with ½ HP semi-hermetic compressor, forced airflow condenser, With variable fan speed controller, water source evaporator (chiller) with recirculation pump, evaporator with defrost heater and variable fan Speed controller, water heat exchanger, pressure switch, flow switch, thermometer & Manometers. Air mixing and recycling system with PID control, modulating control valve, and air preheat and reheat heater with PID controller, precise control of the heating by thyristor phase angle triggers modules. Humidification chamber consists of heater, PID temperature controller with generate the latent heat with wattmeter. Microprocessor based air conditioner & humidifier controller. Digital temperature indicators. Pitot tube and inclined manometer. Ultra low pressure transmitters. Digital anemometer. Ammeters, voltmeter & wattmeter. The mimic diagram c/w test point (4mm jacks) corresponding to all the electrical components of the system, for comprehensive tests.
