Product Details

This apparatus is designed to demonstrate the complete process of a recirculating air conditioning system, including heating, cooling, humidification, and dehumidification, within a controlled climatic chamber. It allows students to observe and analyze how air is conditioned and how different thermodynamic processes can be plotted on a psychrometric chart. The unit features a transparent air duct and an integrated 180-liter climatic chamber. The system includes a full vapor-compression refrigeration cycle with a compressor, evaporator, and condenser, along with electrical preheaters, a reheater, and a steam humidifier. A variable-speed fan controls airflow, and adjustable ventilation flaps manage the mixture of recirculated and fresh air. Multiple digital sensors measure air flow, temperature, humidity, refrigerant properties, and power consumption at various points in the system. Its primary application is in mechanical engineering education for teaching HVAC principles and psychrometrics. The key benefit is the comprehensive visualization and data collection it enables, allowing students to conduct energy balances, plot air conditioning processes on a psychrometric chart, and understand the real-world operation of complex climate control systems.
