Jiangsu HELIKE Fluid Technology Co., Ltd. is a wholly-owned subsidiary of Dongxu Hydraulics. It is specialized in the research and development, design, production and sales of aluminum plate-fin heat exchangers.
●The temperature of the working environment, that is, the temperature of the air to the human body.
●The working environment temperature is also the fan inlet temperature.
●The correct selection of the working environment temperature has an important influence on the heat transfer calculation of the air cooler, the selection of the heat transfer area and the evaluation of economic benefits. Especially the heat transfer coefficient of the heat flow at low altitude (the difference between the medium temperature of the heat flow in the pipeline and the temperature of the working environment is small).
●According to the local summer, the average dry temperature of 5 days is not guaranteed every year.
●Such as: petroleum, petrochemical, chemical and other large-scale industrial installations, when the heat flow medium in the pipe has strict requirements on the heat flow outlet, this method is basically adopted.
●When the temperature changes, the air volume adjustment mechanism is generally required to control or adjust the operation of the system.
●In some energy-saving low-temperature differential energy recovery systems or low-temperature differential heat transfer processes, the area of the air cooler is often large, and equipment investment becomes the main equipment feasibility contradiction.
●In this kind of equipment, the heat flow load of the air-cooled radiator can change with the seasons, so it is more reasonable to take the annual average temperature as the design temperature.
● Calculated according to the local average temperature of the hottest month.
●If the outlet temperature of the air cooler is allowed to change within a certain range, or the control is not too strict, for example: the air cooler is equipped with rear-end cooling (water cooler, refrigeration unit, etc.). There are also examples of applications where maximum monthly temperatures are used in the design of air coolers.
●In most areas of our country, the average drying temperature cannot be guaranteed to be below 35 ℃ within 5 days of summer every year.
●Based on the local average annual temperature.
●It is more reasonable to use an air-cooled radiator when the temperature close to the ambient temperature is greater than 15 ~ 20 ℃.
