The invention provides an automatic online defrosting method and a refrigerating device. The refrigerating device comprises at least two refrigerating circuits, wherein the refrigerating circuits are mutually connected in parallel, each refrigerating circuit comprises an evaporator, an expansion valve, an electromagnetic valve and a needle valve; in each refrigerating circuit, the electromagnetic valve, the expansion valve, the evaporator and the needle valve are sequentially arranged along the flowing direction of a refrigerating agent and are connected through pipelines; the at least two refrigerating circuits comprise a first-end refrigerating circuit and a tail-end refrigerating circuit, the electromagnetic valve and the expansion valve of the tail-end refrigerating circuit are also connected with an independent pipeline in parallel, and a second electromagnetic valve is also arranged in the independent pipeline. According to the automatic online defrosting type refrigerating device disclosed by the invention, the normal running of the refrigerating device can be ensured while the defrosting of the evaporator is ensured, and the refrigerating device has no need to be shut down; therefore, the running reliability and the running stability of the refrigerating device are maintained, meanwhile, the temperature in a refrigerating environment is enabled to be kept constant within a certain range.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to an automatic online defrosting method and refrigeration equipment. Background technique [0002] For low dew point air conditioning units using fluorine systems, due to factors such as large changes in outdoor operating conditions or matching cooling capacity, evaporator frosting is a frequent problem, so the problem of evaporator defrosting must be considered. The traditional defrosting method generally requires the unit to be shut down, and the unit cannot operate during defrosting. In this way, the temperature and humidity in the room fluctuate greatly, which cannot meet the temperature and humidity requirements of the room, especially for rooms with relatively high temperature and humidity accuracy requirements. [0003] Therefore, in view of the above problems, it is necessary to propose a further solution. Contents of the invention [0004] The object of the prese...
