Comprehensive heat metering system with multiple charging modes

Abstract

Disclosed is a comprehensive heat metering system with multiple charging modes. The comprehensive heat metering system comprises a room temperature sensor, a room temperature acquirer, an electric valve, a household heat meter, a repeater, a building heat meter, an acquisition calculator and a data storage server. The comprehensive heat metering system can achieve three existing mainstream metering modes including an on-off time-area method, a heat meter method and a temperature-area method. A user can charge in any one of the three modes during actual usage as well as a composite charging mode with one as the main and the others as the auxiliary, thereby obtaining reasonable charging. The comprehensive heat metering system can also achieve free combination according to the actual requirements of users by omitting part of modules to meet the specific requirements of the user. Besides, the comprehensive heat metering system can upload the indoor temperature information of the user in real time and set the upper limit of the indoor temperature of the user remotely, thereby providing basis and means of production adjustment for heat supply enterprises and saving energy sources. The comprehensive heat metering system with the multiple charging modes is wide in application range and can be applied to split heat metering of all the centralized heat supply occasions.

Description

technical field [0001] The invention relates to the technical field of heat supply metering, in particular to a comprehensive heat metering system with multiple charging methods. Background technique [0002] The heating metering reform has been promoted in our country for many years. In order to better promote the heating metering reform and cooperate with the implementation of heat metering, the Ministry of Housing and Urban-Rural Development promulgated the "Heating Metering Technical Regulations" JGJ173-2009 in 2009. According to regulations, there are currently four methods of household heat metering, namely: radiator heat distribution method, household heat meter method, flow temperature method and on-off time area method. The above four methods are currently used in domestic heat metering transformation, and the on-off time area method and the heat meter method are used more often. No matter which of the above four methods is used for direct or indirect measurement T...

AI Technical Summary

Problems solved by technology

The above four methods are currently used in domestic heat metering transformation, and the on-off time area method and the heat meter method are used more often. No matter which of the above four methods is used for direct or indirect measurement The user's heat consumption is charged according to the user's heat consumption. The common problem is that it cannot solve the problem of heat transfer between households, and it cannot solve the problem of unfair heat charges caused by different positions of rooms in the building.

Therefore, it is very difficult to popularize the heat metering reform work. Although some heat metering devices have been installed, it is difficult to charge according to the heat metering.

In view of the problems existing in the above four methods, some enterprises have developed the temperature area method in recent years, which has made some progress in the rationality of billing compared with the previous methods, but there are also difficulties in the fixed installation of temperature sensors. , the user opens the window to affect the energy saving, whether the allocation method is scientific and reasonable, etc.

In addition, the above-mentioned heat metering methods are all fixed, and when the user's demand changes, it is impossible or difficult to meet the new demand of the user
