[0094] For example, at this time, the outdoor temperature Tout is 35°C, and the indoor temperature Tin is 35°C. The current system load rate is calculated by setting the temperature T. The total temperature difference ΔT required by the system can be obtained from the current matching of the condenser, evaporator, and fan in the system, and the specific calculation methods involved will not be repeated here. For example, the calculated ΔT is 30°C;
[0095] At this time, according to the indoor return air temperature of 35°C, the target evaporation temperature Te1 at this time is 15°C, and the calculated result is calculated by the compressor limit value (upper limit value) and the outlet air temperature limit value (upper limit value). Check, for example, the general compressor Te limit value is 26°C, while the upper limit value of the outlet air temperature is 24-26°C, and the limit value for the evaporation temperature is, for example, 20°C; because the Te calculated at this...

The invention discloses a variable frequency air conditioner control method and device, electronic equipment and a medium. The variable frequency air conditioner control method comprises the steps that a set temperature value of an air conditioner is obtained, and a current indoor temperature value is obtained; according to the set temperature value, the current indoor temperature value and a preset deviation threshold value, the system load rate of the variable frequency air conditioner is determined; a current outdoor temperature value is obtained, and information of a target device of the variable frequency air conditioner is obtained; a total heat transfer temperature difference is determined according to the current outdoor temperature value, the information of the target device and the system load rate; and a refrigerating system of the variable frequency air conditioner is controlled by taking the total heat transfer temperature difference as the target, so that the air conditioner system can be controlled to operate at relatively high energy efficiency under different load rates and different outdoor temperature values, and the energy-saving operation of the air conditioner system is realized.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a control method, device, electronic equipment and media for frequency conversion air conditioners. Background technique [0002] With the introduction and advancement of a series of information projects such as "Internet +" and "Big Data Application", the scale and quantity of data centers have developed rapidly, and they have become a major power consumer in the information society. In order to ensure the efficient and reliable operation of the data center, it is necessary to quickly discharge the heat generated by the servers in the data center during operation. [0003] In order to reduce the energy consumption of the data center and rationally allocate social resources, it is necessary to optimize the refrigeration system of the data center and other organizations. The optimization of the inverter air conditioning system is more about the optimization of the...
