Air Cooler selection advice and the origin of the stain

Home Air Cooler products as the rapid development of electrical and mechanical products in China in recent years, a series of new products are emerging, in the refrigeration and air conditioning, evaporative cooling, and solution humidification industry products increased year by year, and the export of product types and countries also continue to expand, the quality of the product requirements are also increasing. Next, let's take a look at the advice on choosing an Air Cooler and the origins of the stain. Here are some answers.

Seven tips for choosing the right Air Cooler.

Firstly, the Air Cooler can be installed horizontally, vertically, or diagonally, but so that the cooling tower condensate can crudely follow the heat transfer tube to prevent the heat transfer tube from holding water and reducing the heat transfer characteristics and increasing the frictional resistance. Second, the lower side of the Air Cooler should be installed with a water seepage tray and drainage tap water pipe. When the cooling towers are stacked up, the middle of the 2 cooling towers should be placed right in the middle of the water seepage tray and drainage tap water pipe, and the drainage tap water pipe should be equipped with an exhaust valve to prevent the intake of gas. Thirdly, according to the gas mobility orientation, Air Cooler can be connected in series or tandem equipment. When according to the amount of gas, it is appropriate to choose a parallel connection; it is stipulated that the air temperature drop is too large when it should be connected in series. For Air Cooler connected in parallel, the water supply pipeline should also be connected in parallel; for Commercial Air Cooler connected in series, the water supply pipeline should also be connected in series. Cool water and gas should flow in reverse. Fourthly, in the Air Cooler, the gas and Freon should be reverse liquidity, the quality flow rate of its rain-facing surface, generally choose 2.5-3.5kg/(㎡.s), when the quality flow rate exceeds 3kg/(㎡.s), a bumper should be added after the water cooler. For cooling towers with water sprinklers, bumpers should generally be placed. Fifth, Air Cooler cool water inlet temperature, should be at least 3.5 ℃ lower than the gas inlet and outlet dry bulb temperature, cool water warming should be selected 5-10 ℃, and its flow rate should be selected 0.6 to 1.5 m / s. In-room temperature air conditioning unit overload, the volatile temperature cannot be less than 0℃; low load to avoid its surface layer of frost. Sixth, the number of columns of cooling towers along the gas inflow is generally selected from 4 to 6 rows, not suitable for higher than 8 rows. Seventh, in the case of using an Air Cooler, additional indices should be taken into account for reasons such as area ash, scale accumulation in the inner chamber, etc., to enhance the total area of heat exchange. The reduction in thermal conductivity can also be filled by reducing the initial temperature of the water during the running session.

How does Air Cooler staining occur?

Normal cooling water is rich in calcium, magnesium ions and acidic physiological brines, and when the cooling water with these chemicals passes over the surface of the metal, it reacts with the organic chemistry of the metal material, and inorganic salts are formed. In addition to this, the oxygen present in the cooling water will also corrode the metal, not to mention causing rust stains to form. Once the rust scale has occurred, it will first reflect the heat transfer results of the special tool, and in the case of the rust scale, there is also the possibility of blocking the pipeline, which will generally contribute to the complete acquisition of the heat transfer characteristics of the special tool. If the application continues, it will lead to higher power consumption and consequently higher costs. It is therefore important to keep the Air Cooler cleaned at all times so that it can be used to extend the life of the special tool, develop its effects, consume drive power and time, and reduce costs.
