Air conditioning technology. In combination with the base unit the operational model of a full air conditioning system is created. The model is plugged onto the base unit, secured using fasteners and connected with refrigerant hoses to become a
complete refrigeration circuit for the air cooler.
The room climate is created by the interaction of air temperature, heating temperature and air humidity. The purpose of room air conditioning is to shape the room climate in accordance with the requirements of people or sensitive goods.
This model introduces the operation of an air conditioning system and the recirculating air and outer air operating modes. 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,
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, digitised and represented dynamically in the software. The conditioning of the air can be monitored online in the h-x diagram.
Fundamentals and individual components are represented in the educational software for Performance assessments check the learning progress. With the aid of the authoring system further exercises and performance assessments can
be created.
The unit shall perform the following experiments and investigations:
