EXTENDED DUTY PRESSURE SWITCH ANW1620

The pressure switch in the refrigeration system plays a crucial role in the field of refrigeration. Its main applications and functions include:

  1. Protecting the refrigeration system: The pressure switch in the refrigeration system is primarily used to protect the system from abnormally high pressure, preventing damage to the compressor. When the high pressure in the refrigeration system exceeds the set value, the pressure switch will react, cutting off the relevant circuit to prevent the pressure from continuing to rise and damaging the system.

  2. Controlling the power supply circuit: The refrigeration system pressure switch installed on the high-pressure side of the refrigeration system mainly controls the power supply circuit of the outdoor fan motor. At the same time, it also controls the AC contactor coil of the compressor power supply control circuit.

  3. Protection against low return pressure: The refrigeration system pressure switch installed on the compressor’s low-pressure return air pipeline is used for the protection of the system against excessively low return air pressure. When system failures lead to insufficient refrigerant or blockage, causing insufficient compressor return air and overheating, the pressure switch will activate the protection mechanism.

In summary, the refrigeration system pressure switch not only provides protection against high and low pressure in the refrigeration system but also controls the power supply circuits of key components in the refrigeration system, ensuring its normal operation. In refrigeration equipment such as air conditioners and refrigerators, the refrigeration system pressure switch is an indispensable key component.
