Accompanying drawing 2 is the schematic diagrames that patch of 004 two-shipper group control section, and other parts are identical.
Use the main control part separately, can be used for the calandria refrigeration plant, they do not have electric defrosting, do not have blower fan yet.
The main control part is united use with the defrost control section, can be used for the refrigeration plant of the air Natural Circulation of finned evaporator, they have electric heating tube, but do not have blower fan.
With main control part, defrost control section, and the air-cooler control section unite use, can be used for air cooling refrigeration equipment, it needs electric defrosting, and has blower fan.
Two-shipper group control section and main control are partly united use, can be used for the occasion that a refrigeration plant uses two refrigeration unit, two refrigeration unit are controlled by same temperature, but other control is independent separately.
The present invention compared with prior art has following obvious advantage:
1. for adapting to the requirement of various refrigeration plant electrical equipment control, more unified specification is arranged again, it is designed to the split combined type, various refrigeration plants can each takes what he needs.
2. realize once control, simplify circuit, without contactor etc., make the workman exempt to do distribution board, raise the efficiency, reduce fault. Can reduce cost for some refrigeration plant.
3. owing to adopt unified method for designing, particularly adopt unified Split assembled connector to connect method for designing, strengthened the alternative ability of different manufacturers product.
4. be convenient to widely maintenance. 1. when the refrigeration plant of display was not installed in maintenance, the maintenance personal carried a cover display, can see easily storehouse temperature and defrost time etc.; 2. looking up the fault reason at the scene only need judge roughly that out of joint it is taken off of which part change one and get final product, and a few minutes can finish; 3. needn't carry the accessories such as various electrical equipment control that different manufacturers is produced, only need respectively be with one and get final product. This is even more important for backwoodsman maintenance.
