How to solve the common blockage fault of biological heating low temperature unit

If the biological heating low-temperature unit fails during use, it may make the equipment unusable.
For some common blockage faults, it needs to be solved in time, so it is more convenient to solve it
.

Blockage is one of the faults of the bioheating cryogenic machine, but its impact is very large
.

For example, it can cause the compressor to not stop, the cooling speed is slow, or even no cooling,
etc.

These are relatively serious problems for equipment, and once they appear, they will seriously affect the function of biological heating low-temperature units
.

So why does the biological heating low-temperature unit have such a phenomenon, here is a simple share with you
.

Ice blockage is caused by the entry of moisture into the refrigeration system.
The process requirements for vacuuming during maintenance are not strict, moisture is brought in during the process of adding refrigerant, and there is water in the compressor after leakage.
When the compressor is under the action of high temperature The refrigerant is converted from a liquid state to a gaseous state, so that the moisture enters the thin and long capillary tube with the circulation of the refrigerant
.

These are the basic reasons for their appearance
.

　　Regarding the blockage of the biological heating low-temperature unit, it can be divided into full blockage and half blockage.
The fault phenomenon is that the evaporator is not frosted or the frosting is not satisfied, the standby temperature of the condenser is too high, and the filter drier or the condenser has no temperature by hand.
When the process pipe is opened, a large amount of gas is ejected, which proves that the system circulation is not smooth
.

After the ice block is formed, the exhaust resistance of the compressor is large, the condenser is not hot, and the evaporator can be heated for a period of time, and it can work normally, but the fault reappears after a period of continuous operation, which is the characteristic of ice block
.

If these phenomena occur in your biological heating low-temperature unit, you can make a preliminary judgment as to what is the cause
