The air outlet and the air return port are arranged on the same side of the cabinet, thereby ensuring that the air can circulate between the indoor environment and the cabinet. The air cooled and reduced in temperature by the refrigeration system is blown into the indoor environment through the air outlet under the action of the fan, thereby cooling and reducing the temperature of the indoor environment. The hot air on the side far away from the air outlet in the indoor environment flows back to the cabinet through the air return port under the action of the air pressure, is re-cooled and reduced in temperature and is blown into the indoor environment again, thereby realizing the circulation of the cooled air. The evaporator is arranged on the air circulation path between the air outlet and the air return port in the cabinet, so that the air can contact the evaporator as much as possible in the circulation process, thereby improving the cooling effect of the evaporator on the air. The air conditioning system provided by the utility model can cool and reduce the temperature of the indoor environment by arranging the refrigeration system in the cabinet outside the indoor environment, without arranging the indoor unit inside the data center. The utility model avoids the occupation of the machine room space by the air conditioning system, improves the utilization rate of the machine room space, reduces the installation difficulty and cost of the air conditioning system, thereby realizing the effect of reducing the operation cost of the data center.

[0105] Cooling mode includes: air conditioner refrigeration mode, mixed cooling mode and natural cooling mode.
