Description
Technical Details

The air conditioning model (AR – 002) is a part of the Refrigeration and Air Conditioning Training System. By connecting the model to the base unit electrically and hydraulically, a complete refrigeration circuit is created to simulate a full air conditioning system.

This model demonstrates the principles and components of a full air conditioning system.
This model introduces the operation of an air conditioning system and the recirculating air and outer air operating modes.
The room climate is created by the interaction of air temperature, heating temperature and air humidity.
The model includes two air ducts with transparent front.
The top air duct serves as climatic chamber whilst the bottom air duct contains the air cooler, two electric air heaters and a steam humidifier the air in the duct system can be cooled, heated, humidified or dehumidified.
The individual system components are operated via the software.
Temperature and humidity before and after the evaporator and in the climatic chamber are recorded by sensors, digitized and represented dynamically in the software.
The conditioning of the air can be monitored in the h-x diagram.
The model is connected to the base unit electrically by data cables and hydraulically by refrigerant hoses.
