Coolnet CYA S 28D/U | Computer Room Air Conditioners
| Products Introduction Computer room air conditioners refer to a kind of special precision air conditioners (also called constant temperature and humidity air conditioners) that can fully meet the environmental conditions of the computer room. It is a new model that has gradually developed in the past 30 years. When comfortable air conditioners were used in the early computer rooms, there were often problems such as unstable operation of the equipment in the computer room due to improper control of environmental temperature and humidity parameters, interference in data transmission, and occurrence of static electricity.

Features
| 1. Cooling capacity measurement conditions: inlet air dry bulb temperature 23°C, wet bulb temperature 17°C; condenser inlet air dry bulb temperature 35°C, wet bulb temperature 24°C.
2. Evaporation coil: direct expansion type evaporator, the copper tube is a high heat conduction seamless copper tube with a hydrophilic punched aluminum sheet, the aluminum sheet is tightly attached to the copper tube and mechanically expanded to make the copper tube and the aluminum sheet close fit.
3. Reasonable refrigeration cycle, convenient maintenance, compact structure, small appearance, all maintenance and maintenance can be carried out frontally, which effectively reduces the installation and maintenance space, and is convenient for installation, transportation and maintenance.
4. Safe and reliable operation, excellent and stable performance, all compressors use high-performance scroll compressors, air blowers use low-noise and high-efficiency centrifugal fans, and refrigeration system accessories are from internationally renowned brands with stable performance.
5. The humanized microcomputer control system is simple and convenient to operate. High-precision PLC control technology, multi-level energy adjustment, small fluctuations in indoor temperature and humidity, temperature accuracy of ±0.5°C, humidity accuracy of ±3%
