Problems solved by technology

[0013] The purpose of the invention is to invent a flow temperature heat metering method and a flow temperature heat metering system based on room temperature, which are used to measure the heat charges of multi-storey (high-rise) residential building heat users; The sensor is difficult to solve the problem of the influence of the initial room temperature of the time-on-off area method and the problem that the more radiators measure the less heat; solve the problem of radiator occlusion and replacement encountered by the radiator heat distribution meter method, and avoid the heat meter method. To solve the water quality problem and solve the problem of changing the flow sharing ratio of the flow temperature method

specific Embodiment approach 1

[0048] Specific implementation mode one: the room temperature-based flow temperature heat measurement method described in this implementation mode includes the following steps:

[0049] Step 1. Determine the actual room temperature of each room in the building: t nio = t no ±Δt; t no is the average value of the indoor temperature of each household at the initial stage; Δt is the difference between the actual indoor temperature and the average temperature of the thermal user, and its size reflects the balance of the room temperature of the building;

[0050] Step 2. Determine the initial temperature difference of supply and return water: Calculate the user’s initial supply and return water temperature difference according to the actual room temperature of each user and the measured user’s supply and return water temperature using formula (8); in actual conditions, heat the user’s supply and return water The temperature difference is indicated by the superscript "`";

Abstract

A flow temperature heat measuring method based on room temperature and a flow temperature heat measuring system relate to a heat measuring method and a flow temperature heat measuring system. The invention solves the defects of the heat measuring method presently used and the measured heat can be directly used for charging. The method includes the following steps of: determining the actual temperature of all rooms in a building as well as the temperature difference of heat users between supply and return water in actual situation; arranging a heat meter at the entrance of the building as well as a flow controller and a supply and return water temperature sensor in a user inlet; and sending the measured supply and return water temperature and the heat supply quantity of the building to an integrator or a data center to complete heat calculation in a wired or wireless way. The heat measuring system is simple and reliable, convenient in installation, low in fault rate, long in service time and easy for people to understand and accept for heat charge sharing result and in accordance with the consumption level as well as understanding and acceptance degree of Chinese common people, and realizes the heat measuring objective that the heat users in the same building have the same heating area and the same temperature comes with the same heat charge to be paid in the same time.

Description

technical field [0001] The invention relates to a flow temperature heat metering method and a flow temperature heat metering system for realizing the method. Background technique [0002] Since the 1980s, my country began to pay attention to the problem of metered heating. At present, the heat measurement methods used in my country mainly include: temperature area method, radiator heat distribution meter method, flow temperature method, household heat meter method, and on-off time area method. [0003] 1. Temperature area method [0004] The temperature area method is based on the fact that the volume heating heat index and the height of the building are constant, the outdoor conditions of the building are the same, and the heat consumed by the building is related to the indoor temperature and the building area, so it can be obtained by Measure the indoor temperature of the room to measure the heat of the building. This method solves the measurement problem of heat transf...
