Precision Air Conditioner For Server Room

Precision air conditioner for data room refers to the special precision air conditioner for computer room that can fully meet the environmental conditions of the computer room. It is a new model developed in the past 30 years. Compared with the comfort air conditioner with the same cooling capacity, the special air conditioner for the computer room has a large air volume and a small enthalpy difference, which also increases the evaporation temperature of the unit, which improves the cooling efficiency and thus improves the economy of the unit. The precision air conditioner for the computer room can also simultaneously The relative humidity in the room is accurately maintained within the preset range to achieve the effect of constant temperature and humidity in the entire computer room。

Product Introduction Technical Parameter

Precision Air Conditioner

Feizhong precision air conditioner adopts advanced fuzzy logic control or PID mediation technology;It has the function of large-capacity fault alarm record storage;The unit has overvoltage, undervoltage and other alarms and fault diagnosis, alarm recording functions, as well as automatic protection, automatic recovery, automatic restart and other functions;

Realize real-time monitoring of all components: accurately and clearly display any accidents and abnormal operation conditions and record the operating periods of fans, compressors, humidifiers and electric heating in real time, which is convenient for customers to repair and maintain;

Crisis management: heaters and humidifiers have simple braking procedures that can still meet basic cooling needs in preset emergency situations.

Air-conditioning units and modules can realize inter-connection and mutual monitoring without using a computer, and automatically adjust the operating status of each module, so that the unit is always in the best operating state, ensuring reliable operation of the unit and reducing operating costs.

High Efficiency And Energy Saving

Double control point logic program to avoid competitive operation;

High-efficiency scroll compressor, low-cost and efficient operation;

EC fan, high efficiency, low noise, adjustable air volume pressure head;

Rapid dehumidification control to avoid excessive start-up of electric heating;

The air channel is completely isolated, even if it is debugged and maintained, it will not affect the air supply work;

Perfect control logic ensures low-torque startup of the compressor, reducing the impact on the power grid;

The fan of the outdoor unit adopts stepless speed regulation control to achieve the best cooling efficiency.

High Reliability

The design and selection of unit equipment is higher than the industrial standard;

Hydrophilic aluminum foil heat exchanger, longer life;

Fully enclosed high-efficiency scroll compressor;

Suitable for the requirements of frequent switching cycles and long-term operation of precision air-conditioning systems;

Compressor energy efficiency ratio is high;

Low exhaust temperature, low compression ratio and high efficiency;

There is no reciprocating inertial force, and the operation process has good balance;

Anti-oxidation coating technology for all welding points, which can be used for a long time in harsh environments;

Strict selection of high-quality components;

A variety of configuration options: such as electric heating tube/PTC ceramic electric heating, electrode humidifier/infrared humidifier/film humidifier, etc.;

The metal frame G4 standard filter is adopted, and the filtering effect is good (G4 level), which can make the air in the machine room clean and dust-free; it can be washed repeatedly; and the maintenance is very convenient. It is more suitable for computer rooms with high cleanliness requirements.

Compact Size

The unit is carefully manufactured using high quality components. Small footprint, the unit can be operated and maintained from the front.

Powerful Intelligent Control System

The control system has two stages of microprocessors. After setting the parameters on the display, remove the display, and the unit will continue to work; when the air conditioner controller fails, other air conditioner controllers can be used to work without affecting the operation of the unit, which improves the reliability and guarantee of operation sex;

The network monitoring method is flexible and supports a variety of network monitoring methods. Various networking monitoring methods such as remote, short-range, and power network can be realized. The communication interface has various forms such as RS485, and an open communication protocol is provided free of charge;
