Embodiment Construction
[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] Embodiment of the compressor frequency calculation method:
[0020] Such as figure 1 In the single-car air-conditioning system shown, when controlling the frequency of the compressor in the existing air-conditioning system, the ambient temperature in the vehicle and the required temperature are usually collected first, and the control quantity is calculated according to the temperature difference between the ambient temperature in the vehicle and the required temperature. Quantitative control of the frequency of the compressor. Such as figure 2 As shown, on the basis of the existing technology, this embodiment increases the influence of the ambient temperature outside the vehicle when calculating the control amount of the compres...

The invention relates to a compressor frequency calculation method and device for an automobile air-conditioning system. The method includes: collecting at least influencing factors including the ambient temperature outside the vehicle, the ambient temperature inside the vehicle, and the required temperature; For the temperature difference, the frequency of the compressor is controlled at least according to the temperature difference and the ambient temperature outside the vehicle, so that the frequency of the compressor is positively correlated with the temperature difference and the ambient temperature outside the vehicle. The present invention adjusts the frequency of the compressor according to the ambient temperature outside the vehicle. When the ambient temperature outside the vehicle is high, the frequency of the compressor is correspondingly increased to meet the demand for temperature regulation; when the ambient temperature outside the vehicle is low, the compressor Reduce the frequency, so as to ensure the cooling effect while taking into account the energy saving and adaptability of the air conditioning system.
Description
technical field [0001] The invention relates to the field of automobile air-conditioning control, in particular to a compressor frequency calculation method and device for an automobile air-conditioning system. Background technique [0002] As a device for adjusting temperature, the air conditioning system is widely used. The traditional air conditioning single cycle system is mainly designed for a single space, such as a room, a car, etc., such as figure 1 Shown is the structural schematic diagram of the existing air conditioning system, figure 1 The air conditioning system in China includes a compressor. The outlet of the compressor is connected to the inlet of the condenser through a high-pressure pressure sensor or a switch. The outlet of the condenser is connected to the evaporator through a regulating valve. The sensor or switch is connected to the inlet of the compressor, thereby forming a complete air-conditioning single-cycle system. [0003] The operating frequen...
