Energy consumption calculation method and system and air conditioning unit

Abstract

The invention discloses an energy consumption calculation method and system and an air conditioning unit. The energy consumption calculation method comprises the following steps of establishing a characteristic calculation model of key parameters and energy parameters; capturing the key parameters during operation of an electric appliance, and inputting the key parameters into the characteristic calculation model to obtain corresponding energy parameters; inputting the energy parameters into a preset energy consumption calculation model to obtain a theoretical energy consumption value; uploading the key parameters and a theoretical energy consumption value to a server, establishing a data comparison table of the key parameters and the standard energy consumption value by the server, acquiring the corresponding standard energy consumption value from the data comparison table by the server according to the key parameters, calculating an error between the theoretical energy consumption value and the standard energy consumption value, and updating a correction coefficient in a preset energy consumption calculation model. The physical model is used for calculating the energy consumptionof the electric appliance, and the online operation energy consumption condition of the electric appliance can be obtained without an additional sensor or an electric meter.

Description

technical field [0001] The invention relates to the technical field of energy consumption calculation, in particular to an energy consumption calculation method, system and air conditioning unit. Background technique [0002] With the continuous improvement of living standards, electrical appliances are widely used in various places. Taking air conditioners as an example, my country's building energy consumption accounts for about 25% of the total social energy consumption, and the proportion of HVAC energy consumption in building energy consumption can reach 40%~60%, while the energy consumption of residential air-conditioning in my country has increased by 7 times in 15 years, and the growth rate is too fast. Solving the problem of energy consumption of air-conditioning has become an urgent problem to be solved. [0003] Evaluate whether an air conditioner is energy efficient The market uses the Energy Efficiency Index (Energy Efficiency Index) to evaluate, generally divide...
