Normal heating and cooling time of buildings

The normal heating and cooling time of the building is determined according to the local heating time. The national standard heating temperature is 16 to 18 degrees Celsius, and the heating time is one winter. Users below the national heating standard 14 degrees Celsius can refuse to pay.

Take Beijing as an example. The legal heating time in Beijing is 165438+ 10/5 to March of the following year 15. This year's closing time has been determined as June 15 at 24: 00. In case of special circumstances, such as meteorological experts can advance heating or delay stopping heating by analyzing the weather conditions below 5℃ for five consecutive days in Beijing, which can be said to be "depending on the day".

According to Beijing's long-standing practice and relevant regulations, the shutdown time is generally March 15. But under special circumstances, there are also times when "watching the weather to keep warm". For example, after March 15, the average daily temperature is lower than 5 degrees Celsius for five consecutive days, or extreme weather such as heavy snowfall may extend heating.

Heating treatment after stopping heating:

After stopping heating, the heating in residents' homes will gradually cool down. Relevant departments remind users that if it is necessary to dismantle and change the heating after the heating season, they must contact the heating unit or the property department to avoid unnecessary losses caused by residual water in the heating. Heating units can provide heating transformation services for residents to ensure the normal operation of heating in the second year.

Even if the heating is turned off in a few days, residents don't have to worry that the room temperature at home will suddenly drop. Because heating needs a process to start and stop, even if heating is stopped, the heating in citizens' homes will not cool down immediately, but will gradually cool down, so there will be no obvious discomfort.

Don't dismantle the heating facilities without authorization. After the gas supply is stopped, the heating enterprise will carry out water maintenance on the heating pipe network, and there is always water in the heating facilities. Once dismantled privately, it is easy to cause flooding.

Don't drain the water in the radiator and pipeline, because the water in the radiator and pipeline is softened water after antiseptic treatment, which can effectively isolate the air from the corrosion of the radiator and pipeline and prolong the service life of the radiator and pipeline.

After the heating stops, must the water supply pipe and return pipe be closed? After heating, users should close the water supply pipe and return pipe main valve at home in time to prevent water leakage during water and pressure testing in the coming year. Due to thermal expansion and contraction, individual heating pipes and joints may leak water after the supply is stopped, so residents should pay attention to inspection. In case of water leakage, please contact the heating enterprise to close the valve and ask professionals to repair it.

Geothermal heating users need to do maintenance. Geothermal users should remove the decontamination device on the water separator and clean the filter. If necessary, please ask professionals to thoroughly clean the geothermal pipeline. Generally speaking, the cleaning cycle of geothermal energy is 2 to 3 years.
