Light turbulence medical air purification system

Abstract

The invention relates to a light turbulence medical air purification system which comprises a fresh air unit, an air supplying ceiling and a return air treating machine. The fresh air unit is providedwith a draught fan, a fresh air filtering module, a humidity and temperature adjusting device and an air conditioner device; the air supplying ceiling is arranged at the top of a medical room and provided with an air supplying ceiling module to mix, filter and disperse fresh air and return air, so that the fresh air and the return air enter the medical room in a light turbulence mode; and the return air treating machine comprises a return air draught fan and a return air filtering device. According to the light turbulence medical air purification system, an 'air conditioner function' and a 'purification function' are separated, and energy consumption is greatly reduced under the precondition that the use function is met; and the fresh air draught fan and the return air draught fan are provided with brushless direct current motors, and through changing of the motor rotary speed, the fresh air volume and the return air volume are adjusted to meet the demands of operating rooms of different types.

Description

Technical field [0001] The present invention generally relates to the field of medical ventilation facilities, in particular to a weak turbulence medical air purification system. Background technique [0002] Currently, mainstream medical ventilation facilities use unidirectional flow clean technology. Unidirectional flow, also known as "laminar flow", refers to the airflow passing through the air purification device or clean area in the same direction and approximately parallel streamlines. The judgment condition for unidirectional flow is: the deviation of the streamline passing through the clean area from the ideal straight line does not exceed 14°. However, the latest medical research data shows that unidirectional flow ventilation operating room has a higher risk of postoperative infection. [0003] In addition, most of the current medical air-conditioning systems use centralized treatment (dehumidification, temperature adjustment) and filtration of fresh air, and circulatin...

Problems solved by technology

The "primary return air" system is simple, but all the return air is dehumidified by the circulation unit and reaches the dew point temperature of the machine (usually lower than 16°C), so it needs to be heated to reach the supply air temperature, resulting in "cold" and "hot" balance , not only wasting cooling capacity but also consuming heat, which is very energy-inefficient

The "primary and secondary air return" system can achieve energy-saving effects, but in order to realize automatic control, automatic control valves and actuators need to be added, resulting in high failure rates and difficult debugging in practical applications, making it difficult to popularize the system
