The invention discloses a multi-connected type fresh air system and a control method thereof. The multi-connected type fresh air system comprises an outdoor unit, a fresh air ventilator, at least oneindoor unit, a first temperature detecting module, a second temperature detecting module and a control module, wherein the fresh air ventilator communicates to the outdoor side through an air tube; the at least one indoor unit and the fresh air ventilator are in parallel connected to the outdoor unit; the first temperature detecting module and the second temperature detecting module are separatelyused for detecting an air supply temperature of the fresh air ventilator and the indoor environment temperature corresponding to each operation indoor unit; the control module is used for obtaining atemperature difference value delta T1 between the indoor environment temperature corresponding to each operation indoor unit and a set temperature when the fresh air ventilator and the at least one indoor unit simultaneously operate, obtaining a temperature difference value delta T2 between the air supply temperature and the set temperature of the fresh air ventilator, and controlling the air outlet amount and the refrigerant amount of the fresh air ventilator and each operation indoor unit according to the temperature difference value delta T1 and the temperature difference value delta T2. Therefore, the multi-connected type fresh air system can control the air outlet amount and the refrigerant amount of the fresh air ventilator and each operation indoor unit, so that the refrigerating and heating effects of each operation indoor unit are improved, and user experience is improved.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a multi-connected fresh air system and a control method for the multi-connected fresh air system. Background technique [0002] In related technologies, fresh air fans are more and more used in people's production and life. However, the problem in the related technology is that due to the characteristics of the fresh air return air from the outdoor and its large heat exchange area, most of the refrigerant flows to the fresh air, thus reducing the normal flow of the fresh air in the same multi-line system. The cooling and heating effects of indoor units affect user experience. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. Therefore, an object of the present invention is to provide a multi-connected fresh air system, which can ensure the cooling and ...
