Construction method for energy consumption model of existing building air conditioner and energy consumption prediction method for air conditioner

The invention provides a construction method for an energy consumption model of an existing building air conditioner. The construction method comprises the steps of acquiring the energy consumption ofthe building air conditioner, the indoor and outdoor dry-bulb temperature, the solar radiation amount, the indoor and outdoor relative humidity and the rated power of each heating device in a building; calculating the energy consumption of a building envelope according to the outdoor dry-bulb temperature, the indoor dry-bulb temperature and the solar radiation amount; calculating the total energyconsumption of the internal disturbance of fresh air according to the energy consumption of the building air conditioner and the energy consumption of the building envelope; calculating the per-capita fresh air volume of the energy consumption model of the building air conditioner, the number of persons and the coefficients of performance of illumination and equipment according to the total energy consumption of the inter
