1. equipment application scenarios determine: the air cooler to buy is for the production of components (such as home appliance industry) or products (such as food industry) cooling, or for specific space (such as laboratory, test chamber) cooling, this is the first to determine the factor, and the size of the air cooler is closely related to the specifications.

     2. Determine the temperature control range of the equipment: the type of the cold air cooler should be determined according to the temperature range required by the customer. The temperature control range to the low temperature below zero is the low temperature type.

     3. Determine the air supply range of the equipment: the air supply range of the air cooler is related to the application scenario and the volume of the equipment. In the selection, the manufacturer should communicate with the detailed data, provide the necessary parameters of the application scenario of the air cooler and the equipment, and help determine the compressor power, fin size and other key component parameters of the equipment.

     4. equipment air supply air volume and wind speed: the air supply volume and wind speed of the air cooler can be adjusted intelligentially, so it is necessary to know the specific needs of the equipment or space cooling, from high temperature (or normal temperature) to the specific number of degrees and the site area. Calculate the required air volume and wind speed according to the calculation formula (N=V× N /Q, n-fan number (units), V-site volume (m3), N-air change times (times/hour), Q is the single air volume unit of the selected fan model is m3/h) and experience, and then match the motor, fan, outlet aperture and other data that can provide such air volume and wind speed. Determine device parameters.
