Educational training equipment,Experiment Apparatus, XK-RLU-1 Experimental training device about the measurement to refrigeratin
1,Product description
This product is a practical training device used for quantitative analysis of a system loading, which demonstrates the refrigerating principle, energy balance of the evaporator and condenser, and helps students know about cooling performances of different condensing temperatures, the operating of electrical equipment, and how to collect data by the data acquisition unit and various sensors so as to give quantitative analysis to the system loading.
This device is composed of a variable load compressor, an extension-type condenser, five different sensors, fluid viewing glass, and a heating tube. The electric control system includes leakage protectors, a scram button, digital display of alternating current, a DC voltmeter, an ampere meter and a power meter, a motor speed controller, and a tube heating controlling device. It is equipped with an intelligent monitor, data and temperature acquisition modules used for 5 sensors and 2 temperature ways respectively. It is installed 4 universal wheels for its easy mobility.
