Radiation air conditioning system and application thereof

Abstract

The invention discloses a radiation air conditioning system which comprises a mounting room, a radiation circulating unit and hollow radiation wallboards, wherein the hollow radiation wallboards are separately embedded into inner walls of the mounting room, blowing ports and exhaust ports are formed in inner panels of the hollow radiation wallboards, and outer panels of the hollow radiation wallboards are directly exposed in the mounting room; the radiation circulating unit comprises an air conditioning outdoor unit and an air pipe indoor unit, a blowing side of the air pipe indoor unit communicates with the blowing port, and an air return side of the air pipe indoor unit communicates with the exhaust port. By applying the same to a conventional convection air conditioning operating room,the system can at least bring the technical effects: (1) the air distribution is more uniform and clean blind areas in a uniform speed laminar flow intraoperative area are avoided, so that the infection risk of a patient is reduced; (2) temperature distribution is more uniform, so that the somatosensory comfort is improved; (3) anesthesia control is facilitated, so that the anesthesia awakening time and the recovery time of the patient are shortened; (4) body temperature control is facilitated, so that the hypothermia risk of the patient is reduced and the intraoperative risk is reduced; and (5) the system is more energy-saving.

Description

technical field [0001] The invention relates to the technical field of medical air conditioning, in particular to a radiation air conditioning system and its application. Background technique [0002] With the development of human society, the demand for the health and medical industry has increased, and the demand for modern clean operating rooms in many domestic hospitals is increasing. The core index of the clean operation department is to put forward strict regulations on the parameters of the purified air environment. At present, people are not only satisfied with the requirements for parameters such as operating room temperature, humidity, and cleanliness, but also pay more and more attention to the physical comfort of personnel, Many details, such as the guarantee of uniform laminar flow and the maintenance of patient's body temperature, put forward more humane and stricter requirements, but relatively traditional convection air conditioning systems are difficult to s...

AI Technical Summary

Problems solved by technology

[0004] Traditional convection air-conditioning system, the temperature distribution is uneven, the temperature near the patient in the operation area has a large temperature difference compared with the surrounding area or the room temperature actually detected, the patient's body surface temperature is low in summer, and the patient's body surface temperature is high in winter

Surgical anesthesia itself will inhibit the patient's body temperature mechanism, which is likely to cause hypothermia in patients, while traditional convection air conditioning increases the probability of hypothermia in summer. Intraoperative low temperature is likely to cause perioperative myocardial ischemia, coagulopathy, and wound infection. Increase intraoperative blood loss, prolong postoperative recovery time, prolong the recovery period of patients and other adverse symptoms; and intraoperative high temperature also has an adverse effect on body temperature and physical fitness, which will increase the patient's basal metabolic rate, prone to metabolic acidosis, and hypercapnia hypoglycemia caused by excessive glucose metabolism, and even induce cerebral edema and diffuse edema throughout the body;

[0005] Indoor temperature and humidity are completely regulated by the air outlet condition of the air supply ceiling. In order to offset the heat dissipation in the operating room, the temperature of the air supply above the patient area is too low, which is likely to cause the risk of hypothermia during the operation;

[0006] The indoor temperature distribution is uneven, resulting in inconsistent body temperature for patients, surgeons, anesthesiologists, etc., and poor human comfort. For the temperature of the room, only low-temperature air supply can be used, which leads to the low temperature of the air exposed to patients in the operation area, and the temperature in other areas is higher than that in the operation area, resulting in a medical staff in the operating room. Even medical staff feel uncomfortable;

[0007] The air temperature of the air-supply ceiling is low, and the density of the cold air blown out is greater than that of the surrounding indoor air. When the cold air sinks, it will shrink, and there will be laminar airflow blind spots. The wind speed becomes faster and it is easy to turbulent flow, which increases the risk of infection;

[0008] It is difficult to control the patient's body temperature, which has a great impact on anesthesia and patient signs

[0009] The reason for the above-mentioned problems is that the proportion of air blown out by traditional convection air-conditioning operating room is higher than the proportion of air in the surrounding area, which will cause airflow contraction. It will form a blind area; in addition, the contraction of the airflow will cause the flow rate of the airflow to increase. The traditional convection operating room airflow has a greater impact on the patient and has a greater impact on the patient's body temperature, which is not conducive to the stable maintenance of the patient's signs.
