Controller of module unit: DFS-312 module unit controller is designed on the base of intelligent programmablemicrocomputer controller and specializes for module unit controller. Its functionof control by inside two-ways electronic valve pushes aside the past "thermodynamical expansion valve" with extraordinary capacity and competitive price. Itsaves on consume of system, makes the structure of pipe more simply and greatlyimproved the output capability of system.Features:The identification function of DFS makes unit maintains specialized. (It can identifyaccurate code number of compressor, fan and water pump.) It drives by absolutetwo-ways electric expansion valve. (The most output capability of each expansionvalve can be 35KW)The timing function of absolute two-ways cooling fan. The modern technology of non-compulsive control makes sure other controllers keep working normally when somecontrol facilities go conk. Particular net frame ensures flexible match of characterhand-operator, display in Chinese and key-press witch.The control technology of especial electronic expansion valve can improve 15% to25% consume of unit. Anti-jamming of EFT reaches grade 4, EMI has measures up grade B of GB/T4343-1995. Simpler frame of unit reduce the manufacture cost (one electronic expansion valve can instead of one cooling valve, one heating valve, retaining valve and Self-adaptive defrosting can relay the frosting time and improveefficiency of defrost to avoiding worsen the defrosting condition of unit.
