Embodiment Construction
[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the following specific examples are only used to explain the present invention, but not to limit the present invention.
[0030] The invention discloses an air-conditioning energy consumption calculation system. The system can quickly calculate the virtual enthalpy difference between the compressor and the evaporator by using the physical parameters of the refrigerant entering and leaving the compressor and the evaporator, and quickly calculate the air-conditioning energy consumption according to the virtual enthalpy difference. energy consumption. In order to obtain a more accurate energy consumption value, the present invention also proposes to obtain a correction factor through big data to correct the virtual enthalpy differen...

The invention discloses an air-conditioner energy consumption calculation method, a calculation system, and an air-conditioner. The air-conditioner energy consumption calculation method includes the steps that 1, refrigerant physical property parameters are collected, virtual enthalpy differences at the positions of an inlet and an outlet of a compressor and an inlet and an outlet of evaporator are respectively calculated according to a calculation device and a preset physical property model, and air-conditioner energy consumption can be calculated according to the virtual enthalpy differences; 2, the virtual enthalpy differences are sent to a server, enthalpy difference modifying factors are obtained by utilizing big data, and the enthalpy difference modifying factors are returned to thecalculation device; and 3, the received enthalpy difference modifying factors modify the virtual enthalpy differences and the air-conditioner energy consumption by the calculation device. According tothe air-conditioner energy consumption calculation method, the calculation system, and the air-conditioner, the air-conditioner energy consumption can be quickly calculated, the calculating precisioncan be improved, and the equipment cost can be lowered.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner energy consumption calculation method, a calculation system and an air conditioner. Background technique [0002] With the improvement of people's living standards, my country's building energy consumption shows a continuous growth trend, and the current challenges in building energy conservation are huge. In buildings equipped with air conditioners, the energy consumption of air conditioners is relatively high, and some even account for as much as 60% of the total energy consumption of the building. In the era of rapid technological development, energy issues are becoming more and more tense, which may restrict the sustainable development of the economy. Therefore, it is extremely urgent to quickly calculate the energy consumption of air conditioners in public buildings, so as to make targeted energy-saving controls. [0003] The prerequisite for cal...
