The indirect natural cooling system of the computer room air conditioner consists of indoor units, outdoor dry coolers (or cooling towers) and water pumps. The system automatically switches modes through the computer room air conditioner controller according to the outdoor temperature and load. The higher the set indoor return air temperature, the longer the natural cooling time using outdoor fresh air can be.
Tips: Taking the indoor return air temperature set at 27℃ as an example, when the outdoor temperature is lower than 24℃, natural cooling can be started and the system can enter mixed mode operation.

Air Cooling Design Principle of Glycol Dry Cooler

The glycol dry cooler heat exchange system uses the indirect use of natural cold sources, also known as natural cooling energy-saving air conditioners. The outdoor dry cooler is used to exchange heat with the outdoor air, and the glycol aqueous solution is used as a coolant to provide a cold source for the energy-saving coil of the indoor unit to reduce the temperature of the machine room. The unit is controlled by a microcomputer. When the glycol return water temperature differs from the machine room temperature by 7°C, the natural cold source can be partially utilized, and the insufficient part can be supplemented by compressor refrigeration. When the above temperature difference is above 14°C, the dry cooler can completely replace the compressor refrigeration to achieve the purpose of energy saving.

Natural cooling air conditioners use the low freezing point of ethylene glycol aqueous solution as a refrigerant for refrigeration and cooling in winter. The higher the concentration of ethylene glycol aqueous solution, the lower its freezing point, so when it is used, the concentration of ethylene glycol solution should be adjusted according to the lowest temperature in the local winter. The specific heat of ethylene glycol aqueous solution is less than that of water, and its specific heat will further decrease as its concentration increases. The concentration of ethylene glycol solution in winter for natural cooling special air conditioners is generally 30%, at which time its freezing point is -28℃ and its specific heat is 3.412KJ/KG·℃. When used in the Northeast region, the ratio concentration of ethylene glycol is 50%, at which time its freezing point is -35℃ and its specific heat is 2.931KJ/KG·℃. It can be seen that the ratio concentration of ethylene glycol solution affects its heat exchange capacity. The heat exchange capacity of ethylene glycol solution and dry cooler can be calculated according to the heat transfer calculation formula.
