Protect PVR series in-row air conditioner is kind of intelligent temperature control product especially suitable for modular data center. It is usually deployed in the cabinet arrangement, installed side by side with the server cabinet, combined with enclosed hot and cold aisle, close to the heat source and efficient cooling, creating an ideal operating environment for the key infrastructure of the data center.
Energy Efficient
- Large air volume, small enthalpy difference, high sensible heat ratio design, to meet the temperature control needs of the server room
- High energy-efficient compressor with electronic expansion valve as standard for fast response and more accurate flow adjustment.
- • High efficiency backward tilting centrifugal fan with low energy consumption and high air volume to ensure uniform temperature and humidity distribution in the server room
- The use of high-efficiency internally threaded copper tubes and hydrophilic layer-plated open-window aluminum fin evaporators for higher heat transfer efficiency
- Outdoor fan with infinitely adjustable speed control, matching condensing pressure operation, energy saving and noise reduction
- Standard with electrode humidifier, higher humidification efficiency and wider application range
Safe and reliable
- Use of rigorously certified, high-quality devices to enhance reliability
- Products are subjected to rigorous and repeated testing and verification, with high standards required for high quality delivery
- 365 x 24 hours non-stop operation, long life design and low maintenance costs
- Highly efficient and environmentally friendly refrigerant R410A as standard
- Threaded quick coupling design for no welding on site
High efficiency and energy saving
- Accurate control of temperature and humidity
- Adopting variable frequency scroll compressor that has 20%~100% dynamic adjustment of cooling capacity output
- Adopting EC Backward Centrifugal Fan, adjusts the speed output according to the real-time thermal load change
- Adopting electronic expansion valve that has fast response speed and precise flow adjustment
- Full frequency conversion design, intelligent control cooling capacity and air volume output on demand to achieve efficient operation
- High return air temperature design improves cooling efficiency
Intelligent control
- 4.3-inch true color touch screen, multi-level password authority, system self-test diagnostic function, more intelligent
- Comprehensive monitoring and display of power supply voltage, frequency, phase sequence, cooling capacity, air volume, temperature and humidity curve and other key information, real-time control of the normal state of the system
- Up to 64 air conditioners can be rotated patrol group control to achieve scheduled rotation, fault rotation, cascading, demand synchronization, anti-competitive operation, etc
- Support power-on self-start and timer on/off functions, easy to manage air conditioners
- Local storage of not less than 1000 history records, easy to view and trace
- Standard RS485 interface, support optional SNMP interface

Remarks:
- The above performance parameters are based on, indoor return air 24℃, relative humidity 50%, outdoor temperature 35℃
- The small room precision air conditioner is divided into two different air supply methods: top front air supply and downflow
- Small room precision air conditioner under the fan type is divided into two forms of fan sinking and not sinking
- Working temperature: -20~45℃, less than -20℃ need to add low temperature components.
