Precautions for antifreeze construction of Vacuum Tube Solar Collector: 1. Flat-plate solar collectors and U-shaped tube collectors must use standard solar heat-conducting media to prevent freezing damage. 2. The above two types of solar collectors should pay attention to the use of antifreeze medium or air pressure test method during pressure test.

Precautions for antifreeze construction of Vacuum Tube Solar Collector:

1. Flat-plate solar collectors and U-shaped tube collectors must use standard solar heat-conducting media to prevent freezing damage.

2. The above two types of solar collectors should pay attention to the use of antifreeze medium or air pressure test method during pressure test.

3. If the water injection method is used for the pressure test, the water in the flow channel must be drained in time after the pressure test, and the antifreeze working fluid must be filled on the same day after the water test and pressure test on the same day, so as to avoid heat collection when the ambient temperature is below 5°C The remaining water in the flow channel of the device freezes and expands, causing the internal flow channel to swell.

4. the correct choice of antifreeze circulating fluid. Use the manufacturer’s standard antifreeze solution or antifreeze cycle working fluid whose freezing point is 10°C lower than the local minimum ambient temperature.

5. If the balcony wall-mounted water tank needs to be disassembled (reconnected to the pipeline) before the house decoration, you should contact the property or solar professional construction personnel to carry out the construction, so as to avoid non-professionals or landlords disassembling and connecting the pipeline incorrectly (connecting the water pipe and The antifreeze medium circulation pipelines are connected together), causing the flow channel of the collector to swell due to water freezing.

6. After the leak detection of the non-pressurized water-flowing vacuum tube solar collector is completed, if the system will not be put into operation (use) in a short period of time, it is recommended to remove the remaining residues in the system pipes and collectors (horizontal plug-in type) in time. The water is drained.

According to the above precautions, the Vacuum Tube Solar Collector will be effectively protected and survive the winter safely.
