Green Breathing Operating Room

Abstract

This invention relates to a green breathing operating room, comprising: an operating room, a first air conditioning unit, a second air conditioning unit, and a processing unit. The operating room's air inlet is equipped with a high-efficiency filter. The first air conditioning unit is connected to the operating room, forming a circulation channel. Within this channel are sequentially arranged a first primary filter, a first intermediate filter, an ultraviolet germicidal lamp, a first cooler, a first heater, a humidifier, and a first blower to filter, regulate the temperature, and regulate the humidity of the internal air. The processing unit receives temperature and humidity signals detected by a first detector and controls the operation of the first cooler, the first heater, and the humidifier to maintain stable temperature and humidity within the operating room. This reduces moisture degradation of the high-efficiency filter, extends its service life, and lowers energy consumption and maintenance costs.
