How to deal with the frosting of the chiller?

There are many types of chillers, and customers familiar with this piece are definitely familiar with the chiller. For the frosting of the chiller, many people are ignorant, and then let's learn more about it with LNEYA!

1. If it is a chiller, please check if the opening degree of the expansion valve is too large. The small point can be fine-tuned (if it is an electronic expansion valve adjustable circuit control panel).

2. If the opening degree of the expansion valve is too small or blocked, the liquid supply of the refrigerant will decrease, which will cause the evaporation temperature to be low, causing frost on the fins of the evaporator; if the refrigerant does not flow back to the flow back Continued evaporation in the trachea and compressor will cause frosting of the compressor and return line.

3. Check if the filter is too dirty, or the evaporator fins are too dirty to make the heat exchange effect poor, and the refrigerant evaporation does not flow back to the return pipe and the compressor continues to evaporate, resulting in frost formation.

4. If the operating environment of the chiller is not good, or the air does not circulate, it will also cause the heat dissipation effect to affect the unit frost.

5. Check if the amount of refrigerant is within the standard range. Whether the filling is too much or too little will affect the normal operation of the chiller.

6. Is it the use of multiple chillers in parallel? If the number of units to be turned on is large, it is necessary to check whether the start time of the frosting unit is too long (the combined unit has a control panel to set the opening and closing time of each chiller as required).

For the failure of the chiller, LNEYA tells everyone that it is necessary to use professional knowledge to solve the problem in time, and check the equipment in time to avoid any malfunction.
