The invention provides a temperature and humidity independent processing integrated system for an air conditioner. The integrated system comprises a central control system, a main pipeline, a temperature control unit and a humidity control unit, wherein a first constant-temperature water tank and a heating and cooling coil pipe are arranged in the temperature control unit; a second constant-temperature water tank and a dehumidifying coil pipe are arranged in the humidity control unit; wherein the main pipeline and the central control system constitute a circulation loop; the temperature control unit and the humidity control unit are respectively communicated with the main pipeline and are connected to the circulation loop in parallel. Compared with the prior art, the temperature and humidity independent processing integrated system has the advantages that the temperature and the humidity can be independently controlled by using one set of central control system and two constant-temperature water tanks to respectively supply the temperature control unit and the humidity control unit; meanwhile, more energy is saved by just using one set of central control system in comparison to an existing system using two sets of central control systems, so that the investment is reduced and the same effect is achieved.
