Integrated Refrigerant Dryer Design And Research

Dryer has been developing in our country since 1990 s.As global economic integration of the sustainable development of the increasingly fierce market competition and the improvement of productivity, the requirement to the product of industrial field is higher and higher and same with dryer dew point, the method and inside or outside of the air treatment. Every field(for example: components cleaning, air tools in auto-control, food processing, film production, etc.) is not only satisfied with its basic requirement, but also higher technical requirement. After air compressed, it would become saturated moist air, could produce plenty of water which not only could corrode the piping, also could increase pressure-drop result in equipment failure, the control system failure, affect the normal production. So, it is very necessary to add air treatment after air compressor.Reference to the integrated dryer design, the first side, there are some research lyophilized current mode and the advantages and disadvantages of machines connected to the air compressor, thus avoiding the disadvantage in the subsequent design. In addition, the built-in three-dimensional model of calm after the cold and dry location, the need for air compressor and refrigeration dryer overall support to do FEA stress analysis, theory does not change the overall verification after the cold and dry air compressor integration the stress distribution and strength.In matching the selection process, from cold and dry cooling capacity, dew point requirements and other values start to elect the core components of a refrigeration compressor power and cooling capacity cold and dry. Followed by calculation, you can get the size of the required heat transfer area of the cooler. Calculated based on the sample air flow and fan manufacturers to provide, you can fan selection. After all selection out, according to the size of the sample provided for refrigeration compressors, heat exchangers and fans for each design modeling.In the process logic control, mainly determined pressure protection switch according to the diagram of temperature and pressure, type and performance range of high temperature and low temperature protection switch protection switch.During the performance test, mainly to test the performance parameters under the three conditions which is, in the un-load condition test whether the refrigerant charge excess and deficiency in the standard design dew point is the standard test conditions, test conditions at high temperature in extreme cold and dry work environment whether it can continue running.This thesis will be show how to solve these issues above.
