摘要： Devices are provided for field weakening control of a compressor, including the compressor and a main circuit unit providing power for the compressor. The devices include a compressor rotational speed obtaining unit, and a control unit that compares the rotational speed ω of the compressor with a rotational speed threshold ω1 of the compressor, and controls the main circuit unit according to comparison results. When the rotational speed ω is less than ω1, an output voltage of the main circuit unit is controlled at a fixed value. When the rotational speed ω is greater than or equal to ω1, the compressor is controlled not to enter the field weakening control temporarily and the output voltage of the main circuit unit is controlled to rise, the compressor is controlled to enter the field weakening control when the output voltage of the main circuit unit cannot continue to rise.

摘要： A control method for a multi-split air conditioning system capable of simultaneous cooling and heating to solve the problem that uneven cooling and heating occurs when running an existing multi-split air conditioning system. The method includes calculating the cooling or heating temperature effect deviation of each indoor unit on the basis of the indoor ambient temperature and set temperature of the environment where each indoor unit is located; calculating the total cooling effect deviation and total heating effect deviation of an multi-split air conditioning system on the basis of the horsepower of all the indoor units and the corresponding cooling temperature deviation or heating temperature deviation; and selectively adjusting the degrees of opening of valve boxes on the basis of the total cooling effect deviation and the total heating effect deviation. The method ensures balanced distribution of refrigerant, balanced running effects the units, and avoids uneven heating and cooling.

摘要： An address competition method of a multi-connected type control system. The method aims at solving the problem of how to set an indoor machine communication address in the multi-connected type air conditioner system efficiently. For the purpose, a primary control device (such as an air conditioner outdoor machine) performs broadcasting on each address in a preset address section in sequence. A slave control device (such as the air conditioner indoor machine) responds to the primary control device on the basis of preset responding time and the number of currently broadcasting times of the primary control device. The primary control device to which a communication address is distributed temporarily is responded so as to finish address competition rapidly. Meanwhile, the primary control device can perform continuous broadcasting on one address for repeatedly, so that the competition success rate of the address is increased.
