Water cooled water chiller is one of the cooling system in central air conditioner, uses cooling tower to cool the water, and the cold water is cooling source. Water cooled water chiller has advantages of high efficient, low noise, reasonable structure, simple and stable operation, convenient installation and maintenance, which is comfortable central air conditioner that suitable for hotel, shopping mall, office building, exhibition mall, airport, gymnasium.

 

VWSA(N) series water cooled water chiller (heat pump)is the stable product developed by VICOT with the using of new technologies of international and domestic air conditioning industry, which is designed and produced according to international standard, adopting world famous high quality compressor, system accessories and computerized controller, with the reasonable match and structure design, it’s stable, high quality, low noise and no contamination to outdoor environment.

Features

 

   

1. Optimized design:

The strong and weak electricity systems installed separately to ensure safety.

Flexible high pressure system makes it lifetime longer.

  2. Quality components selection:

Compressors and refrigeration accessories (such as dry filter, thermal expansion valve, liquid supply solenoid, liquid level mirror, high/low pressure control devices) all chosen world-renowned brand products to ensure that the unit reached an excellent level of performance

 

Using the most advanced DAE / DAC efficient heat transfer pipe, heat transfer surface with internal ribbed tube makes the heat transfer coefficient substantially increased; the heat exchanger unique structural design, the best way of copper tube layout and precision of refrigerant control technology, greatly improved the efficiency of heat transfer.

 

3. Simple and stable operation,

       Perfect control

1) Computerized control with standby manual operation system, 2) Compressor operation timing,

3) Compressor automatic start-up sequence, 4) Alarm signals, 5) Alarm reset, 6) Water temperature control, 7) Manual reset high pressure switch, Automatic reset low pressure switch

Protections that ensure its safe and stable operation:

1) Reverse phase,2) lack phase,3) high/low pressure, 4) gas discharge,

5) Outlet water temp. too low (high), 6)

water stopped, 7) antifreeze , 8)compressor overheat etc.

High speed microprocessor is used.

Reserved the terminal for SMS control

Reserved the terminal for PC monitoring hardware

With self diagnosis function, and automatically eliminate software problem, the capability of anti-interference is improved by the software uses redundancy and trap technology with WATCHDOG of hardware.

Advanced touch screen is used, the lifetime of which is more than 1million times of consecutive touch.

Digital display of:

1) Entering and leaving water temperature, 2) Temperature and differential settings, 3) Alarm description

4) Hour meters readout of operation and number of unit and compressor start-ups
