Problems solved by technology
[0005] (2) The energy consumption is large, and the specific power of small and medium-sized air compressors is 6.5kw / m 3 about
[0007] (4) Low reliability. When the humidity of the air is high, the moisture content in the air is high, and the temperature when the air is compressed is high. At this time, the lubricating oil is easy to decompose, and carbon deposits will occur in some key parts of the compressor. Make the operation of the compressor malfunction, so the maintenance rate of the air compressor is high, the maintenance cost is high, and the reliability is greatly reduced

The invention belongs to the technical field of air conditioners, in particular disclosing an air compressor set capable of freezing and drying air inflow. The air compressor set comprises an air compressor, wherein a refrigerating unit is connected on the air inlet at the front end of the air compressor; a compressed air output end of the air compressor is successively connected with an oil separator and an air radiator; and the tail end of the air radiator transports dry compressed air to users by connecting tubes. The air compressor firstly dehumidify air therein in advance so that low air inflow temperature is low, air inflow area is large, low compressor energy consumption is low, small noise is small and reliability is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of air compressors, and in particular relates to an intake air freeze-drying air compressor unit. Background technique [0002] In the prior art, the currently used compressed air freeze-drying method air is compressed by a compressor and then cooled, and then the compressed air is dehumidified by a refrigerator to meet the requirements of users. Specific as figure 1 As shown, after the air is first compressed by the compressor, the rear end of the compressor is connected to an oil separator, and the oil separator is connected to an air radiator and a refrigerator in turn. The compressed air is provided to the user. [0003] This air compressor compressed air freeze-drying method is a mature technology that has been used for many years and promoted in large quantities, but this processing method has the following defects: [0004] (1) The intake air temperature is the ambient temperature, and the temperat...
