The present invention relates to the technical field of
air conditioning load calculation of building envelopes, and in particular to an
air conditioning load and capacity calculation method of an integrated photovoltaic-thermal
building envelope, including: obtaining geographic information, meteorological information, envelope information, and flow channel information of the
building location; calculating the
solar irradiance received by the surface of the integrated photovoltaic-thermal
building envelope based on the geographic information, meteorological information, and envelope information; presetting the temperature of the photovoltaic panel at the initial moment, inputting the meteorological information, envelope information, flow channel information, and
solar irradiance into a preset photovoltaic-thermal building integrated envelope hierarchical model, and performing iterative solutions to obtain the power generation power,
heat generation power, and hourly heat
gain, and respectively calculating the power generation,
heat generation, and
air conditioning load, and completing the
air conditioning load and capacity calculation of the integrated photovoltaic-thermal
building envelope. The present invention can provide a basis for the energy-saving and low-carbon design of the integrated photovoltaic-thermal building envelope.
