As our economy continues to develop and the standard of living of the people continues to rise, the expectations of the general public for the living environment of their homes are also rising, which in turn has stimulated the rapid development of the electrical industry in our country, of which the Air Cooler has become the mainstay of urban consumption. Let's take a look at the performance measures of Air Coolers and the benefits of dry Air Coolers. Here are some answers.
The Air Cooler's variable-speed function is also a measure of the Air Cooler's performance.
Introduction to the advantages of the dry Air Cooler.
The efficiency of the Air Cooler is influenced by the temperature of the working environment and the back pressure value varies with the temperature. In many areas of the country, there is a large difference in temperature between days. In these areas, the Home Air Cooler should be able to adapt easily and quickly to local temperature changes so that the Air Cooler remains in a relatively stable operating condition. To achieve these goals the Air Cooler should be frequency controlled. Changes in ambient temperature directly lead to changes in the back pressure of the Air Cooler. The variable-speed function automatically changes the operation of the Air Cooler to match the temperature change. The inverter speed control allows the airflow to be adjusted very quickly to the output of the turbine. This makes the Air Cooler more energy-efficient, easy to operate, and responsive to control.
If the same amount of heat is transferred and the temperature rise of the cooling medium is the same, the amount of air required will be four times that of water, making the dry Air Cooler very large compared to a water cooler. Crucially, the heat transfer coefficient on the air side is very low, resulting in a very low total heat transfer coefficient for the bare tube Air Cooler, which is approximately 10 to 30 times lower than that of the water cooler. To counteract the effect of the low heat transfer coefficient on the air side, Air Coolers generally use finned tubes with extended surfaces, with a finning ratio of roughly 10 to 24 times. Plate Air Coolers with plate heat transfer elements are also available, as the shape of the flow channel section formed by the plates changes continuously in the direction of flow, enhancing the disturbance. However, due to the narrow flow path of the plate-type Air Cooler, in the cold winter months in the north of China, the flow path is easily blocked by the condensation of the cooling medium in the flow path and is prone to scaling thus blocking the flow path. Due to the all-welded structure, the Air Cooler has to be replaced in case of local damage or blockage, resulting in great waste. Therefore, the finned tube is still the mainstream heat transfer element of the Commercial Air Cooler. The key to strengthening the heat transfer performance of the Air Cooler is to develop a finned tube with low contact heat resistance, high heat transfer efficiency, and low flow resistance. When the interior of the heat exchanger is a fluid of higher pressure, the tube plus ribs is equivalent to replacing the pressure-bearing high-quality tube with a non-pressure-bearing cheap rib, with remarkable economic results.
