What are the preparations before starting the chiller

Water chiller is an energy-saving machine that achieves cooling effect through vapor compression or absorption cycle. Chillers are called cooling water circulation machines, also called chillers, chillers, chillers, chillers, ice chillers, small chillers, industrial chillers, chillers, low temperature chillers, laser chillers, because of the wide range of industries Use, so according to different industries, its aliases are countless. Below we introduce the preparation and installation procedures of the chiller.

　　 The chiller is ready to start up, and the following items must be checked for the first operation:

1. Whether the power supply voltage and the number of phases meet the model specifications, please refer to the nameplate. [Note that the power supply of refrigerators above 3HP adopts three-phase five-wire, and the voltage 380～415V/50HZ power phase lines are separately R, S, T, the neutral line (zero line) N, and the grounding wire is a two-color line represented by E. There is a wrong phase protector inside. When the light does not turn on or the red light turns on for the first time and the fault code and warning signal are displayed, you can switch any two phase wires and close the switch; 3HP The following refrigerators use single-phase power, the voltage 220-240V/50HZ power phase line is L, the neutral line is N, and the ground line is E.

2. Whether the chilled water pipe and the cooling circulating water pipe are connected to the pipeline, and keep the valve open; (please refer to the installation diagram)

　　3. Fill the freezing water tank with water or other freezing media before starting the water pump; (Note: Please use the freezing media according to the requirements)

　　 4. Please pay attention to the running direction of the cooling water pump and whether the tower fan is reversed.
