ZM6150 Refrigeration System with Refrigeration and Freezing Chamber Teaching Education Equipment Condenser Trainer Equipment
* Refrigeration system with 2 different evaporation pressures1
* Simulation of 18 faults
Technical Description
Identifying faults in refrigeration systems requires comprehensive
knowledge This knowledge also includes the design and purpose of the individual components. helps to acquire this knowledge.
The components of a refrigeration circuit with refrigeration and freezing chambers are arranged clearly in the trainer. Solenoid valves enable the individual or parallel operation of the evaporators in the two chambers.
The circuit is equipped with a combined pressure switch for the delivery and intake side of the compressor. The refrigeration chamber features an evaporation pressure controller. The effect of the evaporation pressure
controller on the overall process is being examined. An inner heat
exchanger in the inlet of the two evaporators is used for supercooling the refrigerant to increase the efficiency of the process. At the same time the intake gas is superheated.
An electric defrost heater is available to defrost the freezing chamber.
The simulation of 18 different faults, e.g. faulty solenoid valves or faulty relays, is provided for.
The process schematic at the trainer offers a quick overview. Signal
lamps in the process schematic indicate the operating state of selected
Components.


Relevant measured values are recorded by sensors. The measured values can be read on digital displays. At the same time, the measured values can also be transmitted directly to a PC via USB. The data acquisition software is included.
The most important pressures are additionally indicated with manometers directly at the trainer. The software enables the representation of the cyclic process in the log p-h diagram.
The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
