For example, taking a central air conditioner as an example, the central air conditioner internally comprises a plurality of functional devices, such as a functional device for realizing refrigeration by utilizing heat absorption during liquid vaporization and heat release during condensation, a functional device for supplying water to a central air conditioner end device, such as a functional device for supplying water to an air cooler, a functional device for recovering return water of the central air conditioner end device, a functional device for treating cooling water and chilled water, a functional device for filtering impurities in circulation and the like. In order to facilitate installation, transportation and control of each device, in this embodiment, the functional devices are divided and recombined according to functions, which is equivalent to modularizing the functional devices in the integrated refrigeration station according to functions to form a refrigeration unit (equivalent to a refrigeration module) for completing a refrigeration cycle of an air conditioner, a cooling side system (equivalent to a cooling side module) for completing a cooling water cycle in the air conditioner and a freezing side system (equivalent to a freezing side module) for completing a chilled water cycle in the air conditioner. The functional devices in the unit and the system can be installed in different places in advance respectively, and can also be installed at a target installation point, but even when the target installation point is installed, the installation can be completed according to the corresponding unit and system respectively, and then the assembly is carried out, namely the modular installation is realized, and like the prior art, all the functional devices are installed one by one according to the sequence, so that the connection relation among the functional devices is not compact enough, the occupied area is large, the installation is complicated, the time and the labor are wasted, and the efficiency is lower.

Based on the disclosure of the above embodiments, the present embodiment has the advantages of dividing, recombining, or even pre-installing a plurality of functional devices in the air conditioning integrated refrigeration station, so as to form a refrigerating unit, a cooling side system and a freezing side system, which is equivalent to recombining a plurality of functional devices in the air-conditioning integrated freezing station into three different modules, meanwhile, different connecting ends are arranged on the refrigerating unit, the cooling side system and the freezing side system, so that the refrigerating unit, the cooling side system and the freezing side system can realize quick connection based on the corresponding connecting ends, which is equivalent to realize the modularized installation of the integrated freezing station, simplifies the installation process, improves the installation efficiency, in addition, through the modularized arrangement, the connection compactness among a plurality of functional devices in the refrigerating station is improved, and the occupied area of the air-conditioning integrated refrigerating station is further reduced.
Further, the refrigeration unit in this embodiment realizes refrigeration by a liquid vaporization refrigeration mechanism. Specifically, when a liquid (such as a refrigerant, in this embodiment, circulating water) is in a closed container, there is no other gas in the container except the liquid and the vapor generated by the liquid itself, and the liquid and the vapor will reach equilibrium under a certain pressure, where the vapor is called saturated vapor, the pressure is called saturated pressure, and the temperature is called saturated temperature. At equilibrium, the liquid is no longer vaporized, and if a portion of the vapor is drawn from the container, the liquid must continue to vaporize to produce a portion of the vapor to maintain this equilibrium. Since the liquid is vaporized while absorbing heat, the heat is called latent heat of vaporization. Latent heat of vaporization is derived from the object to be cooled, and cools the object to be cooled, that is, cools circulating water. In order for this process to continue, it is necessary to continually draw steam from the vessel and condense it into a liquid before returning it to the vessel. If the vapor drawn from the container is directly condensed into liquid, the temperature of the required cooling medium, i.e. the refrigerant, is lower than the evaporation temperature of the liquid. The refrigerating working medium is evaporated at low temperature and low pressure to generate a cold effect; and condensed at normal temperature and high pressure to give off heat to the surrounding environment or cooling medium. According to this mechanism, the refrigeration unit in this embodiment includes an evaporator 1 and a condenser 2, and the evaporator 1 is connected to the condenser 2 through a pipe. Optionally, the number of the evaporators 1 and the condensers 2 included in the refrigeration unit is not unique, and for example, multiple sets of the evaporators 1 and the condensers 2 may be included, that is, each evaporator 1 is combined with one condenser 2 to form a combination, and multiple combinations may be included in the refrigeration unit, or multiple sets of the evaporators 1 or the condensers 2 may be selected according to the performances of the evaporators 1 and the condensers 2, so that the evaporation amount and the condensation amount of the two are matched to meet the refrigeration requirement in the air conditioner.

Moreover, the problems of scaling, corrosion, biological slime and suspended solids blockage in the pipeline can be effectively inhibited, and the normal operation of the air conditioner is ensured. In addition, in order to better realize energy conservation and environmental protection, a sewage treatment device can be arranged in the cooling side system and can be arranged at the tail end of the cooling tower 4 for treating the circulating water discharged by the cooling tower 4.
