Abstract

The invention discloses a control method of a cooling system. The control method of the cooling system comprises the following steps that according to the communication condition of a bypass branch, whether the bypass branch is in the communication state or not is controlled; when the bypass branch is in the communication state, according to the cooling liquid current temperature of cooling liquid, the rotating speed of a draught fan and / or the opening degree of a throttling device are / is adjusted. According to the control method of the cooling system, on the basis of controlling communicationof the bypass branch, according to the cooling liquid current temperature, the rotating speed and / or the opening degree of the throttling device are / is adjusted, and therefore the cooling capacity ofthe cooling system is further reduced, and the adjusting range of the cooling capacity of the cooling system is widened.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a control method for a cooling system. Background technique [0002] In modern manufacturing, machine tools are indispensable equipment. During the operation of the machine tool, the heat generated by the high-speed operation of the cutting workpiece and the spindle will cause thermal deformation of the guide rails, spindles and other components of the machine tool, thereby reducing the machining accuracy and the life of the machine tool. Therefore, a cooling system is needed to cool the machine tool during the operation of the machine tool. [0003] The cooling system lowers the temperature of the cooling water by exchanging heat between the cooling water and the evaporator, and uses the cooled cooling water to absorb the heat generated during the operation of the machine tool. In the prior art, a cooling system equipped with a variable frequency compressor adjusts the cooling capaci...
