Introduction
    Yu Jiang water-cool temperature and humidity stabilizing air conditioner uses fully-closed turbine air compressor and semi-closed screw-shaft air compressor. These imported products have famous brands. The newest highly efficient condenser, evaporator, cooling and controlling components, ventilator’s motors, electrical temperature booster, electrical humidity booster are of the famous brands; applying advanced processing technologies and techniques to fabricate. This air conditioner has good features such as accurate temperature and humidity control, good cooling efficiency, stable performance, electrical safety, simple operation, good appearance. Our company’s temperature and humidity stabilizing air conditioner are calculated and tested for accuracy, combining with superior general design; therefore, all parameters meet requirements before launching.

Working principle
    Water-cool temperature and humidity stabilizing air conditioner uses water for chilling, high temperature high pressure gaseous refrigerant escaping from air compressor goes through tubular condenser and chilling 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, high effective 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: DB23oC/WB17℃; the required input temperature of cooling water: 30℃, the required output temperature: 35℃)
    This air cleaning conditioner uses smart controller, combining with high quality electrical heater and humidity booster to perform such funtions as chilling, increasing temperature, absorbing humidity, increasing humidity to control accurately the environmental temperature and room humidity; the temperature accuracy is ±2°C, while the humidity accuracy is ±5%.
Scope of use: The temperature and humidity stabilizing air conditioners are used widely for places which need to stabilized temperature and humidity such as factories and warehouses.

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 are more effective than piston air compressors. They have such dominating features as stable performance, high efficiency, low incident rate, convenient maintenance. 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 or 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 chilling 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 or 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 and humidity 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.

Electrical heater and humidity booster
    The highly effective heaters and humidity boosters are produced by famous brand. Their high humidity absorbing and increasing efficiency helps stabilize factory humidity.

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
