1. Outdoor cabinet air conditioner introduction
The air conditioner is one kind of refrigeration product self-developed for cabinet. It is applicable in the place where the cabinet internal heat is very large, the internal electronic equipment is sensitive to the environment temperature and which should be isolated internally and externally completely. This product has multiple functions, high reliability, and has the feature that it can start to work without complex debugging after powering.
The fan in the internal cycle air path absorbs the hot air from the upside to make air heat exchange by evaporator fins, and sends the cooled air from the downside of the air conditioner. By so, the air in cabinet can cycle to achieve the purpose of lowering the temperature. Meanwhile, The fan in the external cycle air path absorbs the external cold air from the downside, and discharges the hot air from the upside after heat exchange.

3. Applications
The environment of outdoor cabinet is dusty and humid, in order to ensure the clean environment of equipment, it is necessary to use air conditioner to isolate the inside of cabinet from the outside environment. Prevent the entry of foreign matters. At the same time, it can prevent the equipment from being damaged by overheating. Ensure that the equipment has a good operating environment.
4. Feature
(1) Compact structure and small volume
(2) Using famous compressor, because the cabinet air conditioning is generally need to work for a long time, the compressor requirements for air conditioning are very high.
(3) Environmental refrigerant
(4) Low noise
(5) Microcomputer digital display: the cabinet belongs to the unattended type. In order to remotely view the operation status of the equipment and the cabinet temperature, and avoid manually starting the air conditioner on site and setting the temperature point, the air conditioner cabinet has the functions of setting the cabinet temperature, fault code display, low voltage, overheat and over-current fault protection and alarm, etc.
