Introduction
Yu Jiang wind cold temperature and humidity stabilizing air conditioner uses fully-closed turbine type 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 chilling efficiency, stable operation, electrical safety, simple operation. The chilling tower is not used. Our company’s wind cold temperature and humidity stabilizing air conditioners are calculated and tested for accuracy; all parameters meet requirements before launching.
Working principle of machine
Wind cold temperature and humidity stabilizing air conditioner uses wind for chilling, high temperature high pressure gaseous refrigerant escaping from air compressor goes through winged condenser and heat dissipation ventilator 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: DB23℃/WB17℃; the outdoor environment temperature: DB35℃/WB24℃)
This air conditioner uses smart controller, combining with high quality electrical heater and humidity booster to perform such functions 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 stabilize temperature and humidity such as factories and warehouses.
Air compressor
Air compressor: uses fully-closed turbine type 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 operation, 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 type air compressor uses refrigerants such as R22、404c、R407c、R134a)
Tubular condenser and winged evaporator
Condenser: uses various heat exchange copper tubes imported from German, Japan and produced domestically. The heat exchanger copper tubes of high efficiency are internally threaded and the wind guide wing is made of water permeable corrosion- resistant thin aluminum foils in parallel vein pairs, that expand the mechanical tube to tightly link the copper tubes and aluminum pieces together in order to maximize heat transfer efficiency, compact structure, small volume, light weight, high efficiency of heat exchange, easy cleaning and maintenance.
Cooling units
Cooling units: Uses 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 operating air compressor is decided to save the power. Its automatic protection function can prevent the air compressor from damage during operation and extend the longevity of the machine.
Ventilator’s motor
The ventilator used is the high-quality centrifugal one of famous brands, with good features of stable operation, 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
Compressor overload protection devices, overheating coil protection devices, ventilator motor overload protection devices, low-high pressure switch protection devices, phase (reverse-phase, phase shortage) protection devices.
