Embodiment Construction

[0018] now attached figure 1 The present invention is further described:

[0019] This embodiment is a thermal measurement method for an open-loop pipeline heating structure.

[0020] This embodiment is a five-story building with an open-loop pipeline heating structure, which adopts the upper-supply and lower-return heating method, that is, the water supply pipe 9 is laid on the upper floor, the return water pipe 8 is laid on the downstairs, and the water supply riser and the water supply pipe 9 Connected with the return pipe 8, the water flow direction in the water supply riser is from top to bottom, and each water supply riser runs through every floor of the household. Present embodiment is by five users 7 (these five users live on one floor to five floors respectively), each user has three rooms in which three heating radiators 6 are arranged, and each user room has passed through three water supply vertical pipes respectively. 1, 2 and 3 heating metering areas. Among th...

Abstract

The present invention relates to a method for measuring heat quantity provided for user in an open-loop heating system. Said method is characterized by that on the water-supplying riser pipe of open-loop pipeline heating structure a flow measuring point is set, in the front end and outlet of every radiator of said water-supplying riser pipe a temperature measuring point is set respectively, so that they can be formed into a series-connected temperature flow combined arrangement mode; the measured parameters of flow measuring point are identical to three measured parameters required for heating quantity calculation mode of calorimeter, said invention utilizes the summation of heating quantities of all the water-supplying riser pipes in the user so as to obtain the heat amount provided for user.

Description

(1) Technical field: [0001] The invention relates to a heat metering method for an open-loop heating system. (2) Background technology [0002] There are two kinds of heating pipeline structures in existing residences, one is the heating structure of closed-loop pipelines, and the other is the heating structure of open-loop pipelines. The characteristics of the heating structure of the closed-loop pipeline are: the heating supply and return pipelines of each user form a separate closed-loop pipeline, that is, there is only one inlet of the heating water pipe and one outlet of the heating water pipe. The characteristics of the heating structure of the open-loop pipeline are: the heating supply and return pipelines of each user have two or more heating hot water pipe inlets and two or more heating hot water pipe outlets. Therefore, a heating residential building with an open-loop pipeline needs to be equipped with multiple heating and water supply standpipes side by side. A ...
