Abstract
A control method and device for a low-temperature cooling air valve include: obtaining an actual system pressure, an ambient temperature, and a system energy requirement; and determining an opening degree pre according to the actual system pressure, the ambient temperature, and the system energy requirement. The control method is employed to perform combined control on the low-temperature cooling air valve according to the system high pressure, the ambient temperature and the system energy requirement, and can refine the range of opening degrees of the low-temperature cooling air valve and determine an opening degree thereof, thereby facilitating cooling operation of a multi-split air conditioning system in an ultra-low temperature environment, while also increasing the reliability of the cooling operation at low temperature and expanding the operation range.
