Equipment focuses on introduce the structure and principle of each components that
constitute the compression-type refrigerating system. Show the comparison of each kind
of throttling mode and the refrigerant quantity how to influence the Refrigeration effect.
Equipment refrigeration system mainly consists of compressor、heat exchanger、dry filter、
four kinds of throttling device、pressure protection switch、liquid view lens、high & low
pressure meter; Electrical system includes leakage protector、voltmeter、ammeter、digital
display thermometer. Equipment equipped with four universal wheels, convenient for
moving

Equipment Training Project
