Method and system for controlling superheat degree of air-conditioning equipment

The invention discloses a method for controlling superheat degree of air-conditioning equipment, which comprises the following steps: detecting compressor suction pressure P1, compressor suction temperature T1, compressor bottom temperature Td and outdoor environment temperature Th; calculating Tb, DeltaTx and DeltaTd; judging whether Th is smaller than or equal to 0 DEG C, and if so, setting the target suction superheat degree DeltaTm as a first target value, wherein the first target value is -1 DEG C to 1 DEG C; and judging whether DeltaTd is smaller than 10 DEG C, if so, giving an alarm, and if not, adjusting the opening of the electronic expansion valve according the magnitudes of DeltaTx and DeltaTm. The practice proves that the suction superheat degree of the invention is 0-1 DEG C when the outdoor environment temperature is smaller than or equal to 0 DEG C, thereby avoiding the phenomenon of carbon deposition due to overhigh exhaust temperature; only when the compressor bottom superheat degree is greater than or equal to 10 DEG C, the invention adjusts the opening of the electronic expansion valve, thereby still preventing the compressor from liquid slugging in practice when the suction superheat degree is 0-1 DEG C.
