- Shanghai the industrial co., LTD
- product brand:ZHONGYOU
- Numéro de stand：A5M46N1G25
- product specification:
- product category:Air Conditioning-Special used air conditioners-Computer room used
- product introduction:High efficiency and energy saving:
Double control point logic program to avoid competitive operation;
High efficiency scroll compressor, low cost and high efficiency operation.
EC fan, high efficiency, low noise, adjustable air volume and pressure head;
Fast dehumidification control to avoid over start of electric heating;
Full isolation design of air passage, even commissioning and maintenance will not affect the air supply work;
Perfect control logic ensures low torque start of compressor and reduces impact of start on power grid.
The outdoor fan adopts stepless speed control to achieve the best refrigeration efficiency.
The evaporator adopts double V-shape structure, reasonable air distribution, no dead zone of heat exchange, high efficiency of heat exchange and remarkable energy saving effect.
The sinking structure can realize the horizontal air supply under the floor and reduce the resistance loss.
high reliability
The design and selection of unit equipment shall be higher than the industrial standard;
Hydrophilic aluminum foil heat exchanger, longer life;
Fully enclosed high efficiency scroll compressor
It is suitable for the requirements of frequent switching cycle and long-term operation of precision air conditioning system
High energy efficiency ratio of compressor;
Low exhaust temperature, low compression ratio and high efficiency
There is no reciprocating inertia force, and the operation process has good balance
All the anti-oxidation coating processes can be used for a long time in harsh environment;
Strictly select high quality parts;
Various configuration options: electric heating tube / PTC ceramic electric heating, electrode humidifier / infrared humidifier / film humidifier, etc;
The metal frame G4 standard filter has good filtration effect (G4 level), which can make the air in the machine room clean and dust-free; can be repeatedly washed; and is very convenient for maintenance. It is more suitable for the machine room with high cleaning requirements.
Compact size
The unit is carefully manufactured with high quality components. The floor area is small, and the unit can be fully operated and maintained.
Easy operation in case of failure or normal maintenance.
• the operator can enter the space under the floor in almost any area of the room, which is flexible and safe,
No ladder or other equipment is required.
E control system
The control system of the new generation of special air conditioner for precision machine room has many advanced functions:
The controller is equipped with multi-level password, which can make different operators have different operation levels.
The control system has two-level microprocessors. After setting the parameters of the display, remove the display and the unit will continue to work; when the air conditioner controller fails, you can use other air conditioner controllers to work without affecting the operation of the unit, improving the reliability and guarantee of operation.
The network monitoring mode is flexible, supporting multiple network monitoring modes. It can realize remote, short-range and power network monitoring. There are many forms of communication interface such as RS485, and open communication protocol is provided free of charge.
The phase Internet and mutual monitoring can be realized between air conditioning units and each module without computer, and the operation state of each module can be adjusted automatically to keep the unit in the best operation state, ensure the reliable operation of the unit and reduce the operation cost.
Adopt advanced fuzzy logic control or PID mediation technology.
LCD multi line Chinese English switching display is used to display the operation status and control parameters of all components in the unit. With Chinese interface and English interface, friendly man-machine interface.
It can directly set the main refrigeration parameters on the control panel, and can continuously monitor the operation status of all components of the unit.
Large capacity fault alarm record storage function.
The unit has over-voltage, under voltage and other alarm 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 accident and abnormal operation, and record the operation period of fan, compressor, humidifier and electric heating in real time, so as to facilitate the maintenance of customers.
Crisis management: the braking procedures of heater and humidifier are simple, and they can still meet the basic refrigeration requirements after braking under the preset emergency situation.
F auxiliary system
Metal frame G4 standard filter
The filter screen is plate type;
Good filtering effect (grade G4), which can make the air in the machine room clean and dust-free;
It can be washed repeatedly;
Maintenance is very convenient.
V-shaped layout to minimize wind resistance and increase air volume
It is more suitable for the machine room with high cleaning requirements.
Special air conditioning condenser for machine room:
3 / 8 "copper pipe;
Aluminum fins;
German Xerox and EBM fans (optional)
