How to Prevent and Solve Frost Cracking of Surface Cooler?

After a period of time, due to the environment of the region where the surface cooler is located or the nature of the surface cooler itself, there will be different degrees of freezing and cracking, thus shortening the service life of the surface cooler. Then, what is the reason for this situation? And what should be done to effectively solve it?

The main reasons for the freezing and cracking of the surface cooler

1. If the water inside the pipe is not discharged cleanly when it is not used in winter, it will lead to the freezing crack of the meter cooler pipe after the outdoor temperature is lowered in winter.

2. As there is water stored in the pipeline of the cold water system, and the position of the fresh air unit is lower than the main pipe of the system, if the valve of the connecting pipeline is not closed tightly, the water stored in the cold water supply and return pipelines will slowly seep into the table cooler, so even though the drainage operation is carried out, it still leads to frost cracking accident.

Surface cooler it will have different degree of freeze crack, then the surface cooler manufacturers should be how to solve it?

1. Surface cooler has freeze crack, water leakage. The main reason is still because the temperature is relatively low, can not be very good to the new air and the return air for mixing, so that the outdoor air is relatively low-temperature air and cold coil for direct contact, we can add a mixing valve, so that the new air and the return air can be very good to mix.

2. The surface cooler is frozen in winter. The main reason is that in the winter we do not set the preheating coil, so that there is water in the table cooler, and then in the direct inhalation of the outside air and thus frozen. If we don't use the table cooler in winter, we should drain the water inside, and it is better to add a heater in the place of air intake during the design.

3. Strengthen the pipeline insulation effect, exposed water pipes in the external environment will cool down when the temperature drops. Before the pipeline insulation should be taken as early as possible for the insulation measures.

4. In the pipe insulation before the operation to fully check the distance between the pipe and the wall and other pipes, equipment, found insufficient insulation position, the need to rectify the rectification to be rectified. When connecting the pipe sleeve with the pipe sleeve, the end face of the pipe sleeve must be coated with thermal insulation glue, the longitudinal seams of the pipe sleeve are required to be staggered, and the longitudinal seams shall not be vertically downward, and the seams shall be sealed with glue between the pipe sleeve and the pipe sleeve.

5. The condensate of the surface cooler should be handled properly. Can raise the host installation position, under normal circumstances require the host height from the ground should not be less than 30 cm, for the more serious snow and ice areas, it is recommended that at least 50 cm; in the host chassis to increase the heat tape, frost and ice; in the condensate water or frost water diversion pipeline wrapped in the outer wall of the heat tape, to prevent icing.

6. but also for the surface cooler inlet and outlet open tee, installation of evacuation; in the system water solution to add ethanol alcohol; . Add antifreeze in the system; heat pump around the debris and snow in time to clean up and so on, so as to exclude all the adverse factors.

If the surface cooler has been seriously damaged and needs to be replaced, please contact Vrcoolertech to replace the surface cooler with a suitable one.
