Controller of module unit:
DFS-312 module unit controller is designed on the base of intelligent programmable, microcomputer controller and specializes for module unit controller. Its function, of control by inside two-ways electronic valve pushes aside the past "thermo, dynamical expansion valve" with extraordinary capacity and competitive price. It saves on consume of system, makes the structure of pipe more simply and greatly, improved the output capability of system. Plug and play.
Features:
The identification function of DFS makes unit maintains specialized. (It can identify accurate code number of compressor, fan and water pump. ) It drives by absolute, two-ways electric expansion valve. (The most output capability of each expansion, valve 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 some control facilities go conk. Particular net frame ensures flexible match of character hand-operator, display in Chinese and key-press witch.
The control technology of especial electronic expansion valve can improve 15% to
25% 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 improve efficiency of defrost to avoiding worsen the defrosting condition of unit).
