Embodiment Construction
[0011] refer to figure 1 and figure 2 , a refrigeration system is provided, which includes a refrigeration circuit 100 and a purification circuit 200 . Among them, in view of the high scope of application of refrigerant purification in this refrigeration system, the refrigeration circuit 100 described here can be any conventional refrigeration circuit of large-scale refrigeration equipment, which usually includes a compressor 130, a condenser, and a compressor connected in sequence through pipelines. 110 , a throttling element 140 and an evaporator 120 . The structure of each component in the refrigeration circuit will not be described in detail here. The refrigeration system also includes a purification circuit 200 for separating the pressurized gas in the refrigeration circuit 100 . It should be noted here that, generally, for a refrigeration system that has been put into use, there may only be refrigerant in its refrigeration circuit. However, for conventional refriger...

The invention provides a refrigeration system. The refrigeration system comprises a refrigeration loop and a purification loop. The refrigeration loop comprises a compressor, a condenser, a throttling element and an evaporator, wherein the compressor, the condenser, the throttling element and the evaporator are sequentially connected through a pipeline. The purification loop is connected to the refrigeration loop and is used for separation of pressure-keeping gas in the refrigeration loop. The refrigeration loop is connected to the purification loop on the top of the condenser or the top of the compressor. The invention further provides a purification method used for the refrigeration system. The purification method includes the steps that within the first time period, the step S1 that a refrigerant meeting the designed refrigerating capacity is injected into the refrigeration system and the step S2 that the pressure-keeping gas is injected into the refrigeration system so that the pressure in the refrigeration system can be higher than the atmospheric pressure are executed; and within the second time period, the step S3 that the pressure-keeping gas in the refrigeration system is separated and discharged is executed. By means of the refrigeration system and the purification method, efficient and reliable separation of the refrigerant and the pressure-keeping gas can be achieved, and it is avoided that the problems of refrigerant leakage and device corrosion are generated in the transportation process of refrigeration devices.
Description
technical field [0001] The invention relates to a refrigeration system, more specifically, the invention relates to a refrigeration system with a purification device and a purification method thereof. Background technique [0002] At present, there are usually many types of problems in the transportation process maintenance and cost control of larger refrigeration equipment using low-pressure refrigerants. For example, if the refrigerant is pre-charged in the production plant or the space inside the equipment is kept in a relatively vacuum, then due to the low-pressure characteristics in the pipeline, it is easy to generate air and the air contained therein during the transportation of the equipment to the customer's desired installation location. The infiltration of water vapor into the refrigeration equipment will cause corrosion of the metal materials inside the refrigeration equipment. In another case, as shown in patent application WO2015 / 068455, the pressure-holding g...
