Embodiment Construction

[0032] Such as figure 1 As shown, the cooling system proposed by the present invention includes: an object to be cooled 1, a cooling pipeline for cooling the object to be cooled 1, a condenser 2 communicated with the inlet of the cooling pipeline, and a return air component communicated with the outlet of the cooling pipeline , the refrigerant in the condenser 2 passes through the cooling pipeline to cool down the object to be cooled 1, and then sends the refrigerant back to the compressor through the return air component.

[0033] The cooling pipeline includes: an upper cooling pipeline 3 and a lower cooling pipeline 4, the refrigerant in the upper cooling pipeline 3 exchanges heat with the upper part of the object to be cooled 1 to cool the upper part of the object to be cooled 1, and the lower cooling pipeline 4 The refrigerant exchanges heat with the lower part of the object to be cooled 1 to cool the lower part of the object to be cooled 1, the upper cooling pipeline 3 an...

Abstract

The invention discloses a cooling system of an air conditioner, an air conditioner and a control method. The cooling system of the air conditioner comprises: an object to be cooled, a cooling pipeline for cooling the object to be cooled, a condenser connected to the inlet of the cooling pipeline, and a cooling The return air component connected to the outlet of the pipeline, the cooling pipeline includes: an upper cooling pipeline for cooling the upper part of the object to be cooled and a lower cooling pipeline for cooling the lower part of the object to be cooled, and the upper cooling pipeline and the lower cooling pipeline are arranged in parallel. The invention has the advantages of uniform cooling up and down, wide adjustment range, improved system energy efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a cooling system of the air conditioner, the air conditioner and a control method. Background technique [0002] At present, when the large-scale frequency conversion chilled water centrifuge is running, the temperature of the motor winding is too high from time to time, which leads to protection shutdown and condensation. Therefore, the cooling system is a very critical part in the reliability of the centrifuge. The cooling method of the cooling system is commonly used. It is: lead a refrigerant from the condenser to flow from the lower part of the motor to wait for the cooling object to circulate heat exchange and cooling at the upper part. When the cooling capacity of some working conditions is relatively insufficient, it is easy to have uneven cooling and heating of the object to be cooled, which will cause the unit to alarm and stop. Moreover, when condensation occu...
