Item Description

A water circuit serves as load, consisting of a tank with a heater and a pump. The temperature in the tank is adjusted at a controller. The purpose of this refrigeration circuit is the production of cold water. The water flows through the jacket of the coaxial coil heat exchanger, transfers heat to the refrigerant and thereby cools down. All relevant measured values are recorded by sensors. Displays at the respective locations of measurement indicate the measured values. This makes it easy to assign the measured values to the process. The simultaneous transmission of the measured values to a data recording software enables easy analysis and the representation of the process in the log p-h diagram. The software also displays the key characteristic variables of the process, such as the compressor pressure ratio and the coefficient of performance. The clearly arranged components aid understanding. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
