Problems solved by technology
When the temperature or humidity of the outdoor air is higher than the set value, the fresh air direct cooling system will not work
[0004] There is no dehumidification link in the conventional fresh air direct cooling system, which limits its applicability in humid areas
Humid areas usually have high air humidity. Even if the outdoor air is relatively cold, it cannot be introduced into the data center for utilization due to excessive humidity.
Therefore, in humid areas, the running time of the fresh air direct cooling system is short and cannot make full use of the outdoor natural cooling source

The invention relates to the field of refrigeration and air conditioning, in particular to a fresh air unit and an air conditioning system. The fresh air unit includes a dehumidification unit, a direct evaporation unit, a solution cooling unit, and a solution concentration unit; the dehumidification unit dehumidifies the first outdoor fresh air through the solution, and the dehumidified first outdoor fresh air enters the direct evaporation unit, and the solution after absorbing moisture enters the solution to concentrate unit; the direct evaporation unit humidifies and cools the first outdoor fresh air after dehumidification, and the first outdoor fresh air after humidification and cooling is discharged from the direct evaporation unit for air supply; the solution concentration unit heats the solution after absorbing moisture through the indoor return air To remove moisture, the solution after removing moisture enters the dehumidification unit; the solution cooling unit cools the solution in the dehumidification unit through the second outdoor fresh air. The invention can regulate the temperature and humidity of the outdoor air, improve the cooling effect and the utilization time of the outdoor fresh air, and expand the application range of the fresh air unit.
Description
technical field [0001] The invention relates to the field of refrigeration and air conditioning, in particular to a fresh air unit and an air conditioning system. Background technique [0002] The IT equipment in the data center generates a lot of heat, therefore, the cooling system of the data center is very critical. Common types of refrigeration systems in data centers include air-cooled direct expansion precision air conditioners, chilled water systems, indirect evaporative cooling systems, and fresh air direct cooling systems. Among them, the fresh air direct cooling system directly introduces the outdoor low-temperature air into the data room after filtering and humidifying, without intermediate heat exchange links and energy loss, and is the system form with the highest utilization rate of natural cooling sources. [0003] The basic principle of the fresh air direct cooling system is to use outdoor air as the cooling medium of the data center, and then introduce it i...
