AZM6156C Air Conditioning Model Technical Educational Equipment
Technical Description
It is part of the HSI training system for refrigeration and 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 .It 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. A fan between the two air ducts recirculates the air. A motorised butterfly valve in the top air duct allows a change between outer air and recirculating operation. Dependent on the switching of the two air heaters, the air cooler and the 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, 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.Performance assessments check the learning progress. With the aid of the authoring system further exercises and performance assessments can be created.
