Hydraulic selfbalancing design for central heating and household metering systems;

Adjusting method analysis for household metering heating systems;

The recognition and opinions about household metering system;

Dynamic simulation software for room temperature and heating load of household heat metering systems;

Aiming at the current unreasonable heat charge policy,the necessity of heat charge per heat consumption is described;the basic ideas and problems of household heat metering and central control on total heat supply are introduced and the relationship of household heat metering and central control is analysed.

Analyses the main reasons for lower heating efficiency and over high operating energy consumption in the central heating systems and discusses current heating reform turning unit building area based charging system into household heat metering and charging.

Central heating and household measurement is the necessary tendency of heating supply.

Aiming at the household measurement used in central heating system currently,a design was completed,which using the GSM short message to control the central heating turning on or off,or through the pressed key to manually operate and to set fixing time for making it turn on or off.

Regarding the household measurement is commonly applied to central heating system currently,a central heating energy-saving control terminal design was completed,which using the SMS,infrared remote control,setting fixing time,or manual control to turn the valve on or off,in order to save energy effectively.
