The invention discloses an air conditioning system and a pressure adjusting method and a device for the same. The system comprises an outdoor unit, at least one indoor unit and a pressure adjusting device, wherein the pressure adjusting device comprises a temperature sensor, a control unit and flow adjusting units; the number of the flow adjusting units is equal to that of the indoor units; the flow adjusting units are in one-to-one correspondence with the indoor units; the temperature sensor is used for detecting the actual temperature value at a refrigerant discharge pipe in each indoor unit; the control unit is used for determining the target temperature value according to the actual temperature value at the refrigerant discharge pipe of each indoor unit detected by the temperature sensor, comparing the actual temperature value at the refrigerant discharge pipe in each indoor unit with the target temperature value, and adjusting the opening of all or some of the flow control units according to a comparison result; and each flow adjusting unit is arranged at the refrigerant discharge pipe of corresponding indoor unit, and used for adjusting the out-flow of the refrigerant of the indoor unit under the control of the control unit.
Description
technical field [0001] The present invention relates to the technical field of air conditioning, in particular to an air conditioning system, a pressure adjustment method and device for the air conditioning system. Background technique [0002] In recent years, multi-connection products have become more and more popular among users due to their advantages such as free combination, excellent partial load efficiency, flexible use methods and convenient and flexible installation, and their market capacity has also continued to rise. However, most of the current multi-connected units can only meet the installation and use requirements of the height difference between the indoor units within 15 meters, and cannot meet the installation and use requirements of the floor with a larger drop between the indoor units. One of the most important reasons is that when the unit is in heating operation, it cannot effectively solve the problem of poor effect of indoor units on lower floors ca...
