Clean operating room air conditioner ventilation system

Abstract

The invention relates to a clean operating room air conditioner ventilation system, which comprises a fresh air supply system and a constant temperature and constant humidity circulation air supply system, wherein the constant temperature and constant humidity circulation air supply system is provided with a circulation machine set communicating with an operating room; the circulation machine set is provided with an air return section. The clean operating room air conditioner ventilation system is characterized in that the fresh air supply system comprises a fresh air room communicating with external air; a plate type filter screen is arranged in the fresh air room; the fresh air room is separated into an air taking room directly communicating with the outdoor part and an air outlet room connected with a fresh machine set by the plate type filter screen; the fresh air machine set is sequentially provided with a low-efficient filtering section, a middle-efficient filtering section and a sub-high filtering section along the air direction; the air supply end of the fresh air machine set is mixed with the air return section through an air supply pipe; the circulation machine set is provided with a clean air supply ceiling in a connecting part of the air supply pipe and the operating room; air supply openings are uniformly distributed on the clean air supply ceiling; an efficient filter is arranged in each air supply opening. The technical scheme has the advantages that the frequent machine halt for dismounting the filter screen for cleaning can be effectively avoided; in addition, the operation cost is reduced; the service life is prolonged.

Description

technical field [0001] The invention relates to an air conditioning and ventilation system, in particular to an air conditioning and ventilation system for a clean operating room. Background technique [0002] The Chinese patent application No. 201010200944.5 discloses a clean operating room with an intelligent control and purification air-conditioning system. The static pressure box, high-efficiency filter, exhaust fan and its frequency converter, embedded controller, and control panel are composed. The fresh air air conditioning unit, circulation purification unit, and air supply static pressure box are connected in series through the air duct. The high-efficiency filter and the air supply The static pressure box is connected as a whole, the high-efficiency filter is placed on the top of the clean operating room, and its air outlet is the input port of the regulated and purified air on the top of the sterile clean space. It presets air parameters such as temperature, humi...

AI Technical Summary

Problems solved by technology

However, the problem with this purification air-conditioning system is that the air inlet of the traditional fresh air air conditioning unit is set on the outdoor air shaft or on the facade, and the fresh air is directly introduced into the system.

Because the outdoor air is relatively dirty, the filter screen of the indoor filter unit is easily blocked, and frequent shutdowns are required to remove the filter screen for cleaning, resulting in increased operating costs and shortened service life.

[0003] In addition, outdoor fresh air is the largest external dust source that affects the cleaning system; at the same time, Guangdong is a high-temperature and high-humidity area, especially in summer, where the humidity is as high as 90%. If it is used directly, this part of the fresh air must be mixed with the return air of the system and then forced to cool the temperature. After lowering to below the dew point to remove the residual humidity, the heater is used to raise the temperature to reach the air supply state, which will cause very large and unnecessary energy consumption
