Introduction
    Yu Jiang water-cool cabinet type air conditioner uses fully-closed turbine air compressor and semi-closed screw-shaft air compressor. These imported products have famous brands. The new highly efficient condenser, stainless steel evaporator, cooling and controlling components are of the most famous brands globally, applying advanced processing technologies and techniques to fabricate. This air conditioner has good features such as good cooling efficiency, high amount of wind, sufficient residual voltage, electrical safety, stable performance, simple operation, good appearance, low incident rate. Our company’s water-cool cabinet type air conditioners are calculated and tested for accuracy, combining with superior general design; therefore, all parameters meet requirements. We can also design upon special request of customers to provide high-quality non-standard products.

Working principle
    Water-cool cabinet type air conditioner uses water for chilling, high temperature high pressure gaseous refrigerant escaping from air compressor goes through tubular condenser and cooling tower to become low temperature high pressure liquid refrigerant, then expansion valve supplies low temperature low pressure liquid refrigerant to winged evaporator for evaporation to achieve chilling efficiencies. The high-quality centrifugal ventilator helps the refrigerant go through winged evaporator which blows chilling wind out in order to reduce room temperature. (Capacity state: The indoor environment temperature: DB23℃/WB17℃; the required input temperature of chilling water: 30℃, the required output temperature: 35℃)
    Scope of use: the air conditioner is used for places in need of high amount of wind, such as commercial centers, hotels, factories, office buildings, stores and hospitals, etc.

Air compressor
    Air compressor: using fully-closed turbine air compressors of globally famous brand-names such as DAIKIN、COPELAND、SANYO、MANEUROP, Performer, or semi-closed screw-shaft air compressors such as HANBELL, Bitzer, Ref Comp. They have such dominating features as stable performance, high efficiency, low incident rate, convenient maintenance. Their working hour can reach 40,000 hours. Based on customers’ request, one or more air compressors can be used, air compressor can change in accordance with sub-load, automatically interchange operation, balance working hours of air compressors, save power, extend cooling machine’s life span.
(Fully-closed turbine air compressor uses refrigerants such as R22、404c、R407c、R134a)

Tubular condenser and winged evaporator.
    Condenser: using various heat exchange copper tubes imported from German, Japan and produced domestically. The copper tube’s outer surface is processed in low-level ladder shape with sufficient metre, thereby increasing the heat exchange area, enhancing the heat transfer, keeping the best cooling condition for the machine, and increasing machine longevity. The copper tube’s inner surface is glossy, thereby reducing water pressure and making it easy for cleaning and maintenance.
    Evaporator: using various heat exchange copper tubes imported from German, Japan and produced domestically. The internal thread high effective heat exchange copper tube and corrosion-resistance aluminum winged expand the mechanical tube so as to join the copper tube and aluminum pad to promote optimally the heat transfer efficiency and make it easy for cleaning and maintenance. 
 
Cooling Units
    Cooling Units: Using the well-known global brands such as DANFOSS, ALCO, SPORLAN with first-rate quality and superior functionality which helps promote machine efficiency.

Electric control-system
    Electric control-system uses smart PLC、PC touch screen control system in Chinese language with quick response and precise control. The system has functions of room temperature automatic control, load automatic increase and decrease. Depending on load increase or decrease, the number of operating air compressors is decided to save the power. Its automatic protection function can prevent the air compressor from damage during operation and extend the longvity of the machine.

Ventilator’s motor
    The ventilator used is the high-quality centrifugal one of famous brands, with good features of stable performance, high amount of wind and low noise.

Protection devices 
    Overload protection devices of air compressor, over heat protection devices of coiler, overload protection devices ventilator engine, protection devices of low-high pressure switch, phase protection devices (reverse-phase, phase shortage), protection devices of anti-freezing, safety valve
