Embodiment

[0049] Such as figure 1 As shown, a building energy consumption acquisition method based on the reference room thermal model of rural buildings includes the following steps:

[0050] 1) Obtain the calculation conditions for establishing the reference room thermal model of rural buildings, including:

[0051] 1. Calculate the influence of thermal disturbance and external disturbance based on the steady-state heat conduction method;

[0052] 2. Due to different functions, each space can be intermittent in space;

[0053] 3. Ignore the thermal radiation between the inner surfaces of the envelope;

[0054] 4. The temperature of the air inside each space is the same;

[0055] 5. The heat transfer process in the space is a linear steady system;

[0056] 6. After 1 hour of continuous cooling or heating in any space, the temperature will reach a steady state.

[0057] 2) Collect meteorological data of the area where the village and town buildings are located;

[0058] 3) Accordi...

Description

technical field [0001] The invention relates to an energy consumption acquisition method, in particular to a building energy consumption acquisition method based on a village and town building reference room heat model. Background technique [0002] Building energy consumption calculation mainly takes building heating and air conditioning energy consumption as the main research object. The earliest calculation of building energy consumption began in the energy crisis in the 1970s. People urgently needed to know how much energy the building used, and more importantly, how much energy the building could use less, so as to alleviate the impact of the energy crisis. Economic development and social progress are restricted. Energy consumption calculation methods mainly include simplified method and dynamic simulation method. [0003] The common simplified calculation methods include the degree-day method, the equivalent full-load operation method, the effective heat transfer coe...
