Measurer and measuring method for temperature of central heat supply

Abstract

The invention discloses a measuring instrument for heating, in particular a constant-temperature measuring instrument for centralized heating and the measuring way for the instrument. The constant-temperature measuring instrument comprises a main floor pipe, a household water-in pipe, a user radiator and a household water-return pipe. The instrument is characterized in that, the household water-in pipe is provided with an in-household temperature meter, a flowmeter for heating hot water, and a low-temp self-closing valve; the main floor pipe is provided with a main floor pipe temperature meter. The invention indirectly measures the heat amount of the users by measuring the flow of the heating hot water of specific temperature. The measuring way is of simple principle, easy to install, the measurement data are steady, reliable and accurate. The invention allows to distinguish the responsibilities concerning heating, and allows easy locating of any fault in heating, and reduces the users to fetch water from the heating system.

Description

(1) Technical field [0001] The invention relates to a heat supply measuring instrument, in particular to a central heating constant temperature measuring instrument and a measuring method thereof. (2) Background technology [0002] At present, the widely used metering method of urban central heating is: in a heating season, a fixed fee is charged according to the actual heating area. As for the heating quality, a minimum indoor temperature during the heating period is stipulated as the standard for whether the heating meets the requirements. The disadvantages of this method are: 1. It is impossible to charge according to the actual heat consumption, which is easy to cause heat supply disputes. 2. During the heating period, the room temperature is not up to standard, and the user cannot effectively complain because of the authority of the measurement. 3. It is impossible to distinguish the different heating effect requirements of different heating users and the actual heat ...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: 1. It cannot be charged according to the actual heat consumption, and it is easy to cause heat supply disputes

2. During the heating period, the room temperature is not up to standard, and the user cannot complain effectively because of the authority of the measurement.

3. It is impossible to distinguish the different requirements of different heating users for heating effect and the difference in actual heat consumption caused by the difference in thermal insulation and energy saving effects of different buildings, so it is impossible to encourage users to take the initiative to save energy and develop intrinsic enthusiasm for energy-saving buildings
