Calorie metering method and calorie metering system

Abstract

The invention provides a heat metering method. In the heat metering method, actual indoor temperature Tnpij, design indoor temperature Ts and average heat consumption qs of a unit area within a metering time period are taken as acquired parameters, better fairness and resonableness can be achieved by balancing the heat consumption of a user by integrating the two factors, the user can be favorably promoted to take certain heat-insulation measures, such as reduction in the frequency of opening doors and windows and arrangement of energy-saving doors and windows with better heat retention property, in order to reduce indoor heat loss as much as possible, that is to say, while the same heat supply effect is guaranteed, the heat loss is reduced, and the corresponding heat consumption is lower. In addition, the invention further provides a heat metering system for metering heat.

Description

technical field [0001] The invention relates to the technical field of heat measurement, in particular to a heat measurement method. In addition, the invention also provides a heat metering system for metering heat. Background technique [0002] At present, there are mainly five heat measurement methods stipulated by the industry: radiator heat distribution meter method, household heat meter method, flow temperature method, on-off time area method, and temperature method. [0003] Among them, the first radiator heat allocometer method is to apportion the total heat supply of the building by using the proportional relationship of heat dissipation of each group of radiators measured by the radiator heat allocometer. The premise of this method is that the heat distribution meter and the radiator need to be matched in the laboratory to obtain the corresponding data of the radiator before it can be applied. There are many types of radiators in China, which brings disadvantages t...

Problems solved by technology

Adopting this method is the most fair and reasonable in form, but the correction of measurement results is a difficult problem to solve

Although after more than 10 years of research, a specific and scalable acquisition method has not been formulated so far, which makes some professionals question the feasibility of this measurement method

[0005] The third method of flow temperature is to apportion user heat by continuously measuring the temperature difference between the inlet and outlet of radiators or household independent systems that share risers, and combining the calculated flow ratio between each riser or household independent system and the thermal inlet. method; this method measures the heat supply of the system, but the pre-measurement workload is relatively large, and it cannot solve the heat cost disputes caused by room position correction and heat transfer between households

The temperature method does not take into account the heat factor, and the same room temperature does not mean the same energy consumption
