Abstract

The invention provides a heat metering method based on a household radiator heat distribution meter method realization heating system and a heat metering system thereof, relating to the technical field of heat metering. According to the method and the system, a problem that the metering can not be carried out by using an existing heat metering method when a heating user radiator model, installation and use conditions or a radiator area in a total heating meter management range is different from the design is solved. The heat metering method comprises the steps of measuring the total heat supply quantity of the whole heating system, the actual room temperature of each heating user and temperature of supply and return water, determining integrated thermal characteristic parameters bi and Ai of all radiators in each heating user, and determining the heat allocation of each heating user finally. A unit temperature collection device in the heat metering system collects the temperature of supply and return water pipes and indoor temperature of all heating users on a heat supply branch, and the total heating meter and all unit temperature collection units send temperature information to a computer. The metering system is simple, the range of adaptability is wide, the accuracy is better compared with an existing heat metering method, and the method and the system are suitable for a single user horizontal heating system.

Description

technical field [0001] The invention relates to the technical field of heat metering of heating systems of buildings. Background technique [0002] Since the 1980s, my country began to pay attention to the problem of metered heating. After decades of unremitting efforts, a variety of heat measurement methods have been applied in engineering. At present, there are two technical routes adopted for heat metering of residential buildings in our country. One is to install a total heat meter at the thermal entrance of the building to measure the total heat supply of the building, and then calculate the total heat according to certain measurements. Make an apportionment. The other is the thermal entrance of the building, without setting a total heat meter, and directly setting a household heat meter in each household for measurement. [0003] With the deepening of people's understanding of heat metering, more and more buildings have begun to adopt the first technical route for h...
