ZM6149 Compression Refrigeration System Educational Equipment
Technical Description
The set-up of represents a typical refrigeration circuit consisting of a hermetic compressor, condenser, evaporator and expansion element. Evaporator and condenser are designed as finned tube heat exchangers. The pipes of both heat exchangers are partially transparent to visualise the process of the phase transition during evaporation and condensing. Three capillary tubes of different lengths and a thermostatic expansion valve can be compared as expansion elements.
The trainer is equipped with a receiver for refrigerant. Using the receiver, refrigerant can be added to or removed from the refrigeration circuit. This allows for the effects of overfilling or underfilling of the system to be examined.
The flow rate of the refrigerant is read from a flow meter. Temperature and pressure in the refrigeration circuit and the electrical power consumption of the compressor 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. Parameter changes in the refrigeration circuit can be viewed dynamically in the software’s log p-h diagram.
The well-structured instructional material sets out the fundamentals and
provides a step-by-step guide through the experiments.
Learning Objectives / Experiments
– function and operational behaviour of the refrigeration circuit components
– operation with expansion valve or with capillary tubes of different lengths
– underfilling or overfilling with refrigerant
– thermodynamic cycle in the log p-h diagram
– from the log p-h diagram and in comparison
with the measured values
* determination of the refrigeration capacity
* determination of the coefficient of performance
* determination of the efficiency of the compressor
