Multi-return-trip clean fresh air processing system

Abstract

The invention discloses a multi-return-trip clean fresh air processing system. The system comprises a cavity provided with a fresh air inlet and a fresh air outlet; and a first air way, a second air way, a third air way and a fourth air way communicating with each other are arranged in the cavity in a ventilation direction in sequence. The system changes the traditional single-return-trip linear arrangement to multi-return-trip three-dimensional arrangement, and adopts an internal shortcut communication form to avoid several flows to achieve the flow simplification and the combination optimization. The system further improves the stability of parameters of the humidity, the temperature, the cleanness and the pressure difference of clean fresh air, achieves higher anti-freezing reliability,improves comprehensive efficiency, optimizes the process flows, achieves more prominent energy conservation and environmental protection effects, reduces the volume of related machines, achieves better production and installation manufacturability and higher product adaptability, widens the application field, and facilitates the market development and the benefit improvement.

Description

technical field [0001] The invention relates to a multi-return clean fresh air treatment system. Background technique [0002] At present, for hospitals in China, clean operating rooms and ICU wards are major energy consumers. According to statistics, the power consumption of clean operating rooms often accounts for more than 1 / 3 of the hospital's power consumption, mainly because the clean air-conditioning system in the operating department is a high-energy consumption device. The coordinated control of the clean operating room in terms of winter antifreeze, summer dehumidification, system wind resistance, cleanliness, and constant pressure difference has always been the key and difficult point of the purification air conditioning system to control energy consumption, and it is also the cause of high energy consumption of the purification air conditioning system in the operating department The main reason, especially in coastal areas, is a common phenomenon of out-of-contro...
