Air conditioner outdoor unit system

Abstract

The invention provides an air conditioner outdoor unit system which is provided with a cooling device. The cooling device comprises a first cooling branch with an evaporation cooling module (1), a second cooling branch with an auxiliary refrigeration module (2) and a temperature control module, wherein the evaporation cooling module (1) is used for carrying out evaporation cooling on refrigerants flowing in the evaporation cooling module (1), the auxiliary refrigeration module (2) is used for carrying out heat-exchange cooling on refrigerants flowing in the auxiliary refrigeration module (2), and the temperature control module is used for controlling the cooling device according to monitored outdoor environment temperature to select a mode to carry out switching over between the first cooling branch and the second cooling branch. The air conditioner outdoor unit system can achieve the fact that the outdoor environment temperature is used for cooling the air conditioner outdoor unit system.

Description

technical field [0001] The invention relates to an air conditioner outdoor unit system. Background technique [0002] At present, most of the precision air conditioners for computer rooms used in the industry do not have the natural cooling function, especially Freon units, and the operating temperature of the Freon air conditioner external unit is limited, not lower than -20°C. In this way, the use of Freon units in a large area in the Northeast will be restricted, and such units cannot make full use of the cold source of the outdoor environment, fail to achieve the purpose of energy saving, and cannot meet the current purpose of building a green data center. [0003] The existing computer room air conditioner outdoor unit is affected by the outdoor environment, so the application area is affected. When the ambient temperature is very low, the performance of the outdoor unit will be affected, and sometimes it will even cause the machine to shut down without cooling. In ad...

Problems solved by technology

[0002] At present, most of the precision air conditioners for computer rooms used in the industry do not have the natural cooling function, especially Freon units, and the operating temperature of the Freon air conditioner external unit is limited, not lower than -20°C

In this way, the use of Freon units in a large area in the Northeast will be restricted, and this type of unit cannot make full use of the cold source of the outdoor environment, fails to achieve the purpose of energy saving, and cannot meet the current purpose of building a green data center.

[0003] Due to the impact of the outdoor environment on the existing computer room air conditioner outdoor unit, the application area is affected

When the ambient temperature is very low, the performance of the outdoor unit will be affected, and sometimes it will even cause the machine to shut down without cooling

In addition, when the external ambient temperature is low, the unit cannot make full use of the external ambient cold source for refrigeration, and the compressor continues to work, failing to achieve the purpose of energy saving

[0004] At present, some products using natural cold source for refrigeration have appeared on the market, but due to their large size, complicated pipelines and control systems, they have not been widely used
