Is the R404 refrigerant pressure indicator of the high and low temperature test chamber changing normally?

November 16, 2022

Most users of high and low temperature test chambers choose a temperature range of -60 ° C to 150 ° C. The test chamber refrigeration compressor is a double machine, and R404 is one of them. The user will choose to read the instructions before using the equipment. A good habit, when you see the pressure gauge, there will be doubts, because he will find that the pointer display is inconsistent with the manual. At this time, is there any problem with the refrigeration?

The original R404 refrigerant is a compressible gas that changes with the change of the ambient temperature. If the ambient temperature is low and low, the ambient temperature is high.

So which direction is the indication normal?

Example: When the ambient temperature is between 10 and 35 ° C, the pressure is in the range of 110 to 180 psi at rest. When working, the pressure indication is normal at around 170 to 270 psi. If the pressure exceeds 300 psi, the ambient temperature is too high, or the high and low temperature test chambers have poor heat dissipation performance.

Here we also warmly remind the majority of users, in order to make the life of the high and low temperature test chamber longer, it is recommended to use the test chamber in an environment of 25 ± 10 °C.
