ET 915.06 Model of a Simple Air Conditioning System
Education / GUNT Hamburg / Thermal Engineering and HVAC / Refrigeration and Air Conditioning Technology /
description

ET 915.06 is part of the HSI training system for refrigeration and air conditioning technology. In combination with the base unit ET 915 the operational model of a simple 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. 
  In systems for room cooling the air to be cooled is aspirated from the room by a fan, cooled and fed back into the room. This model demonstrates the principles of room cooling and the components of an air conditioning system.
  The model ET 915.06 includes an air duct with transparent front, fan for air transport, an evaporator as air cooler and an expansion valve. All components are clearly arranged on a panel.
  The individual components of the system, here the compressor and the fan, are controlled via the software included in the scope of delivery of ET 915. The software offers the option to simulate faults.
  The air flow is determined via a pressure measurement using a pitot tube. Temperatures before and after the evaporator are recorded by sensors, digitised and dynamically represented in the educational software.
