1. The requirements of the indoor temperature: when the projector heat sink heating in winter indoor temperature should be controlled at not less than 18 ℃, the average indoor temperature to achieve 16 ℃, but for the elderly and children, 16 ℃ standard is relatively low, but also shoulds not be too high, too high can let a person have the feeling of discomfort, and indoor and outdoor temperature difference is too large to cause colds and other diseases.

2. Air in the exhaust pipe: water circulation is stagnant due to gas accumulation in the pipe, which affects heating. Therefore, in addition to the exhaust valve set on the top floor, manual exhaust valve shall be installed at the end of each group ofheat sink.

3. Water leakage treatment: the heating period of the projector heat sink pipe connection such as leakage, no matter the size can not be solved by themselves, should timely notify professional maintenance personnel, the leakage point for decompression after maintenance, absolutely can not take pressure maintenance, so that the leakage point expansion, pipe damage.

4. The reason of not hot : the whole is not hot, may be due to outdoor water, return water valve is not open.Single family part is not hot, may be due to the top floor did not vent air caused.Theheat sink is half hot and half cool, which is caused by tail gas accumulation. In a word, under the condition of ensuring the circulation pressure and temperature, the main reason of not being hot is gas blocking, which can be solved by venting.

5. Decorate heat sink: decorate projector heat sink should consider to maintain, open hole area should with whole group heat sink can disassemble lift advisable.And adornment component should be mobile type, when heat sink appears problem, can lift conveniently, reveal whole conduit gas slice. The opening of the valve of the riser and branch pipe shall have space for disassembling and replacing the valve.
