The working process of industrial flanged air duct mainly adopts two-stage compression refrigeration cycle, which is caused by different throttling series and intermediate cooling mode. The throttle series is divided into the first throttle and the second throttle. There are two ways of intermediate cooling: complete cooling in the middle, incomplete cooling in the middle and non-cooling in the middle.
Industrial flanged duct refers to a throttle valve from condensation pressure to evaporation pressure. In secondary flow, fan coil unit refers to a throttle valve that throttles condensation pressure to medium pressure, and another throttle valve that throttles medium pressure to evaporation pressure. Intermediate complete cooling refers to the isobaric cooling of low pressure compressor exhaust gas to saturated steam under intermediate pressure. Intermediate incomplete cooling refers to the isobaric cooling of exhaust gas of low pressure compressor, but it is still superheated steam when it is not saturated. Intermediate non-cooling means that the exhaust gas of low-pressure compressor enters into high-pressure compressor directly and does not cool in the middle. Therefore, two-stage compression refrigeration cycle can be divided into five forms.
There are many kinds of positive pressure air outlets and they are widely used. The single-layer louver tuyere can adjust the wind direction up and down, the return tuyere can be matched with the tuyere filter, and the segment angle can be adjusted. There is ABS plastic fixing bracket between the blades. Fixed filter can be removed from the slider when cleaning, and then removed from the slider to continue to use. Double-layer 100-page air outlet is generally used as air supply outlet, and can also be directly used with fan-coil units. It is widely used at the end of central air-conditioning system. It can also be used with the opposite multi-leaf control valve to adjust air volume.
Industrial flanged air ducts are mainly used in air conditioning and ventilation systems, fresh air treatment units and fan coil units of matching products. The main purpose is to eliminate the air noise at the air outlet, and to improve the static pressure of the system and the stable air flow through the static pressure box of the system, so as to make the air distribution more reasonable and achieve the ideal air conditioning effect. The air volume is evenly distributed and installed in the ventilation duct. In the daytime phase, it is easy to control and distribute. The diffuser is correct and coordinated with the day, and the air volume is stable. The silencing static pressure box can also be installed in the ventilation duct of the ceiling structure, which can reduce the installation space, form a harmonious layout and beautiful three-dimensional shape.
Industrial flanged air duct is a necessary accessory for air supply system to reduce dynamic pressure, increase static pressure, stabilize air flow and reduce air oscillation. Generally, galvanized steel sheet is used to make the air supply effect more attractive. Comprehensive understanding of the static pressure box project example: a gymnasium station large area, more seats, small and many air supply channels to meet the demand for air supply on behalf of the traditional duct ventilation system is difficult to achieve, using the audience to establish ceiling space. The process is simple, the applicability is strong, and the effluent quality is good.
