The invention discloses an error correction control method of an air-conditioning system and the air-conditioning system. The error correction control method includes whether the main throttling device is connected to the correct interface according to the first temperature difference of the indoor heat exchanger, and if not, performing correction. If it is wrong, connect the main throttling device to the correct interface. If yes, go to the next step; according to the second temperature difference of the indoor heat exchanger, judge whether the interface of the sub-throttle device corresponding to the i-th subsystem is connected to The i-th throttling device, if not, perform error correction. According to the error correction control method of the air conditioning system in the embodiment of the present invention, it is possible to judge whether the main throttling device and the sub throttling device of the air conditioning system are connected to the correct interface through the self-check mode, which ensures the normal operation of the air conditioning system, and the error correction control The method is simple and reliable, low in cost and high in error correction efficiency.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to an error correction control method for an air conditioning system and the air conditioning system. Background technique [0002] In the related art, in the one-to-multiple air-conditioning system, the main throttling device that controls the refrigerant flow of all indoor heat exchangers and the sub-throttling device that controls the indoor heat exchangers in each subsystem must be connected to the correct interface to ensure that the indoor exchange Otherwise, the indoor heat exchanger will not work normally, which will affect the normal operation of the air conditioning system. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an object of the present invention is to propose an error correction control method for an air-conditioning system. The error correction contr...
