Solenoid Valve Coils (DC) and Electrical Polarity
A common question about solenoid valve coils is whether the electrical current polarity matters in a DC coil. Most coils with lead wires use the same color wire for both terminals and have no polarity markings. The answer is that polarity does not matter. You can connect the positive terminal to either of the two wires without affecting the operation of the valve.

The main purpose of automation is to optimize the performance of the refrigeration system, including:

• Use an expansion valve to control the injection of liquid refrigerant into the evaporator.

• Use the accumulator to compensate for changes in the level of the condenser.

• Use a solenoid valve with coils to control the flow of liquid to the evaporator.

• Protect the system with a safety device to prevent pressure from being too low or too high.

• Use oil separators to minimize oil entry into the system.

• Use a dry filter to prevent damage from moisture and contaminants in the system.

• Use a sight glass to prevent excess or insufficient refrigerant in the system and check the refrigerant condition.

• Minimize repair time with shut-off valves or ball valves.

• Use a pressure regulator to maintain system temperature and pressure at the low and high pressure ends.

• Increase system efficiency with expansion valves, oil separators, and condensing pressure controllers.

Main parts and accessories for automated refrigeration systems:

1. The copper tube is a capillary tube and acts as a throttling;
2. The solenoid valve acts as a control flow no matter where it is. The on/off of the coil determines the switch of the solenoid valve.

The vapor compression refrigeration system consists of the following components to form a closed system. The system is filled with refrigerant, which is driven by the compressor to circulate in the system pipeline, and absorbs heat through the evaporator and the condenser to release heat to achieve the cooling function.

(1) Compressor: The compressor used in the conventional refrigerator is a reciprocating piston type totally enclosed compressor;

(2) Condenser: The condenser of the refrigerator is cooled by natural convection by air, and the refrigerant vapor is condensed into a liquid, and the condensers are respectively placed inside the tank walls on both sides of the refrigerator cabinet.

(3) Evaporator: The evaporator is a component in which the refrigerant evaporates to produce a cooling effect, and has a refrigerating compartment evaporator and a freezer compartment evaporator. The refrigerator compartment evaporator is attached to the foam layer side of the rear wall of the refrigerator compartment, and the freezer compartment evaporator is directly fixed in the freezer compartment tank.

(4) Capillary: The capillary is an elongated copper tube that acts as a throttling mechanism in the refrigeration system.

(5) Drying filter: It is placed between the condenser and the capillary to absorb moisture.
