Water conservancy balance heat metering system and method

Abstract

The invention discloses a water conservancy balance heat metering system and method, and relates to the technical field of devices or methods for measuring heat. The system comprises indoor wireless temperature sensors, indoor temperature controllers, flow switch-on and switch-off controllers, building heat meters and data acquirers, wherein each building heat meter is positioned at a total heating inlet of the corresponding building; each flow switch-on/switch-off controller is mounted on a branch pipe of an entrance of the corresponding house; each indoor temperature controller is positioned in the corresponding house and is connected with a control end of the corresponding flow switch-on and switch-off controller in a wired or wireless mode; each sensor is arranged in the corresponding house; each data acquirer is arranged in the corresponding building; and the data acquirers are used for acquiring relevant information of the sensors, the indoor temperature controllers, the flow switch-on and switch-off controllers and the building heat meters. According to the method, water conservancy working condition balance is implemented by an adjusting means, users can accept the relatively reasonable apportion mode, heating cost is reduced, energy conservation and emission reduction are promoted, and comfort level of residents is improved.

Description

technical field [0001] The invention relates to the technical field of devices or methods for measuring heat, in particular to a water conservancy balance heat metering system and a metering method. Background technique [0002] The realization of metered heat supply is an inevitable trend in the development of the heating industry, and it is also the inevitable result of the marketization of heat supply, and an important symbol of "heat commodity". Our government also attaches great importance to this, and has included this work as an important part of "energy saving and emission reduction". Since 2007, the state has formulated three laws and regulations on "energy saving and emission reduction". It is imperative to pay attention to "energy saving and emission reduction" and the development of heat supply metering, especially the promotion of heat supply metering. Moreover, the government started from the architectural design of the construction source, requiring new resi...

AI Technical Summary

Problems solved by technology

2. Due to the difference in the location of the households, even if the area is the same, the heat consumption of the top-floor side users and the middle household type will be 2-3 times different when the temperature is the same.

3. Because of the quality problems of heat meters and water quality, according to statistics: after installing heat meters, only 30% of them can be used after one year, and only 10% of them can be used after three years

4. The heat meter is a measuring instrument, and it is required to be inspected once a year. Its maintenance workload is huge and the cost is high, and it is impossible to maintain it every year.

5. Water conservancy balance is the premise of heat metering working conditions. Metering can only be performed on the premise of heat supply balance. Without water conservancy balance, the user's on-demand distribution cannot be achieved.

Therefore, the distributor method is very difficult to promote in our country, and there is almost no promotion

[0011] (2) Behaviors such as replacing radiators, installing radiators, and blocking radiators by resident users without permission will affect the measurement effect

[0012] (3) The number of distribution meters is large, the workload of transcription is heavy, and it disturbs the people

[0013] (4) Not suitable for radiant floor heating systems
