What pressure does the refrigerator compressor create?
Different models of refrigerators use compressors of different operating principles. There are regular, linear and inversion. The principles of their operation are different, but they perform the same task: they build up pressure, forcing air or liquids to move in pipes or containers.
Refrigeration units fail for various reasons: freon leaks, thermometer and relay failures, wiring faults. If the compressor is intact and working properly, it can be removed and adapted for various purposes.
It is easily suitable for creating a spray gun to use as a spray gun when working with airbrushing. Another application is as a compressor for inflating tires. The third possible option is the creation of an air pistol for cleaning work surfaces. The fourth option is to assemble a compressor for a pneumatic stapler or nail gun.

Operating pressure in a refrigerator compressor
The operating pressure produced by a standard compressor connected to the refrigerator is ranges from 2 to 4 atmospheres.
This may seem like a small indicator to some, but no more is needed to circulate freon through a closed system; at this pressure it copes with its function perfectly.You also need to understand that when connected to refrigeration chambers, it is specially configured for exactly this power. The regulators keep the work at a certain level so that the refrigerant pipes do not rupture.
What pressure does the compressor create when removed from the refrigerator?
Completely different indicators are given by compressors removed from the refrigerator. It all depends on the specific model, but with proper configuration, any of them can provide at least 15 atmospheres during operation. The longer it is turned on, the stronger the pressure created. Some samples are assembled with a large receiver, capable of pumping up to 50 atmospheres. This will be more than enough to complete almost any task.
Important! When assembling the pump yourself, remember safety. Do only what you are 100% sure of, because working with a compressor is work with high pressure, and therefore is associated with increased danger. An exploding receiver can injure an adult and ruin the environment around him.
How to adjust the pressure in the compressor from the refrigerator
Self-adjustment of pressure is only possible if the person assembling the pump unit has the necessary skills. For proper regulation you will need:
- atmosphere regulator relay;
- pressure gauge;
- receiver.
Operating principle of automatic relay consists of a system for turning the electric motor on and off, as well as relieving excess pressure. When the number of atmospheres in the receiver reaches a critical set point, the relay turns off the engine and the air stops being pumped; the excess air is discharged through the unloading valve.If the power required for operation has dropped, the relay will automatically connect the engine, and it will continue to be pumped.
Important! The relay must be adjusted when the receiver is 40–60% full. In this way, you can establish a real operating indicator and correctly set the point of discharge of excess.
The schematic diagram for connecting an automatic regulator looks like this: it is inserted into the circuit between the secondary motor control circuit and the unloading valve. The connection is made using threaded heads. Two to the receiver - two to the pressure gauge. The remaining connectors are used to install a plug or an additional safety valve.
