Training contents 

(1) Familiar with refrigeration cycle components;

(2) Familiar with basic refrigeration principle, understand the importance of throttling device in refrigeration system.

(3) Observing and touching the external pipeline to observe the state change of refrigerant. The pressure changes of refrigerant along the pipeline are read by pressure gauge, and the values of voltmeter and ammeter are checked.

(4) Digital temperature readings on fan coil units and condensed air outlet indicators;

(5) The influence of throttling device on refrigeration was studied.
