 Intelligent Management System operates

It is an integral part to operate the Building Management System in an independent, high-speed and multi-transmission mode. To cover whole one building, it requires only one centralized controller function and a Commercial type A/C.

 ● SDS System

Multimodal control for a Single unit, Group units, Networks and so on is attainable.

One (1) computer controls 1024 indoors (max) and 512 outdoors (max)


  Individual Calculation System
  Individual Calculation Report

Individual calculation and report output enable management to control each A/C expense timely.


  Easy and effective Group Setting

Group setting is easy and effective to divide the system into 16 groups by start/stop time, by different parameters and so on. Control of 1024 Indoor units can be done easily.

  Weekly operation plan

Weekly plan of A/C operation can be set and automatically in cycle. Advanced schedule, as well as daily operation time, can also be practiced easily.

 Software to decide A/C models
WINDOWS version
Operate directly on easier WINDOWS interface of functions such as load calculation, multi-split/chilled water system selection, clear quotation table output, hydraulic calculation, required capacity with changeable outdoor environment (for multi-split) or nonstandard working standard (for chiller) and so forth. Update in step with further development of the product.


CAD version
Two versions are available: one for compatible with AutoCAD 2000/2002 and the other is AutoCAD 2004/2005. Main functions include load calculation, equipment selection, pipeline setting, configuration of system, quotation table, refrigerant volume calculation, wiring and installation diagram, and so on. Update in step with further development of the product.

 Digital Scroll A/C System
  Concept
Digital Scroll A/C system is composed of multi system with digital scroll compressor. Refrigerant output of its compressor is adjusted and controlled by variable volume mode. The technology involved to the system is most advanced among A/C manufacturers
Basic module
5 basic models, 8, 10, 12, 14 and 16 HP, increment by 2HP

Wide range by free combination

Those 8 to 16 HP basic modules can be combined freely. Smallest 8HP up to the largest 64 HP, by increment of 2HP, precise meets every specific need of customers.


 Digital Scroll A/C Compressor


1. Expand the energy adjusting range: from 10 to 100%
2. Continuously variable energy adjustment.
3. Longer life: life of PWM solenoid valve is average 40 billion times: 30
  years life practically.
4. Using Axial Compliant Sealing technology, high efficiency and
  stability of the compressed refrigerant is guaranteed.
  Principle of operation


* By an exact advantage of Axial Compliant Sealing technology, the
 Digital Scroll Compressor precisely adjust an axial moving range of
 fixed scroll pan. An additional connecting by-pass, between a
 suction inlet and a pressure bore located at a floating sealing point
 of axial stator, bring this advantage of the unit.
* When PWM Solenoid Valve opens, inside pressure of the Bore is
 released. As it is higher than a pressure at a stator top, the
 compressor axis slightly moves upward. High pressure bore and
 low pressure inlet are, thus, mutually connected for pressure
 release purpose.
* When PWM Valve closed, contrary, these two stators are
 connected to make it airtight and loaded condition. To adjust a ratio
 of Compressor, just use On/OFF to control an output of Refrigerant
 at a compressor.
  No Electromagnetic Interference
SDS Digital Scroll system cause no Electromagnetic Interference, as loading/unloading of a compressor is done only by mechanical movement. Telecommunication, Power Stations, Exact Science Labs are, thus, main expected market for the system.

  Longer pipe length to reach variant height
The system requires no Oil Separator nor Oil Recycling unit to load and unload refrigerant due to its higher speed in loading status to move the oil back to compressor. In unloading status, pumping out no refrigerant from compressor.
