Management and maintenance of purification equipment in hospital operating room
(I) scientific planning of heat recovery
The purification facility of medical organization operating room will discharge a lot of heat in the operation stage, which not only consumes resources, but also pollutes the operating room seriously. Scientifically plan the heat recovery, select a better planning scheme, properly handle the heat recovery, make full use of the energy discharged by the purification equipment with the aid of the exhaust system, and adjust the heat energy to mechanical energy and other forms of energy
Source, on the basis of realizing green energy saving, to ensure the gas flow in the operating room and reduce the possibility of patients infected with bacteria.
(II) scientific selection of hardware parameters
When installing purification air-conditioning facilities in the operating room, we should consider various factors and installation standards from multiple perspectives, and scientifically screen hardware parameters. Whether the parameter screening is scientific or not will directly affect the energy conservation, cleanliness and normal operation of the air-conditioning system. When selecting parameters, pay attention to the requirements of temperature and humidity. If the parameters are too high or too low, the energy consumption will be great, and the application cycle of air conditioning system will be reduced. When the external temperature is low, the system parameter design shall not be too high. When the external temperature is too high, the parameters can be appropriately increased to avoid damage to the system due to too large temperature difference.
(III) scientific layout of engineering structure
The operating room in the hospital is generally in a circular mode. The auxiliary engineering structure is built in the middle part of the operating room. The aisle is in the form of two channels. The middle and outer corridors are clean corridors and clean corridors. This pattern can realize the separation of cleaning and pollution, and facilitate evacuation in case of emergency. Based on this, it is effectively unified with various planning standards of purification equipment and comfort system to continuously reduce the air supply load and energy consumption of functional rooms. In addition, the elevator should be equipped reasonably. For the operating room of the hospital, a special elevator should be installed with a certain amount of air supply to achieve the purification effect and the requirements of the Department.
(IV) reasonable control of frequency converter

Many factors will have a certain impact on the continuous operation of air-conditioning facilities in the operating room. Among them, the influencing factor lies in the current generated by the fan operation, which will not only damage the motor shaft, but also affect the air volume of the air conditioner. Improve the scientificity of frequency converter, provide guarantee for avoiding strong current in motor operation, so as to better maintain motor. In addition, the frequency converter is used in the exhaust and supply fans, which brings high value signals to the direct numerical control unit, and effectively cooperates with relevant programs to meet the frequency requirements of the fan operation process, and then the frequency converter is used to adjust all the time, so that the pressure of the entire air conditioning facilities is maintained in a balanced state.

(V) reasonable use of secondary return air
The purification air conditioning facilities in the operating room of the hospital have the characteristics of large air supply volume and large temperature difference between the air supply and the air supply. Generally, the air conditioning system needs to have a large volume under the condition that only one return air treatment is carried out. In the cooling process of the heating plate, the phenomenon of cold and heat offsetting is produced. When reheating, the secondary return air treatment can reduce the occurrence of this situation, and the electric heater can be adjusted to fine-tuning temperature. In addition, the waste of secondary return air energy is not much, which can effectively reduce the cost of equipment and energy consumption. When the external temperature is very low, the indoor and outdoor air can be effectively mixed for reheating, and the secondary mixing can increase the humidity and send it to the base point.
(VI) improve system design
Many details need to be considered in the design of purification air conditioning facilities in the operating room of the hospital. Generally, it includes: Research load, determine various parameters through various ways, and adopt scientific treatment methods to improve the purification performance of air conditioning facilities; research wet load, most of the wet load in the operating room are from medical staff, whose size has certain stability, so dehumidifier can be used to reduce the wet load; in order to fine manage the air of purification air conditioning facilities Quantity, system design details shall be considered, not only the work quality and efficiency shall not be reduced, but also the system shall be easy to operate and the error rate of operation shall be reduced; design cost and follow-up maintenance shall be analyzed to prevent unnecessary expenses from increasing and realize all-round combination.
(VII) regular inspection and maintenance
Regularly organize professionals to check the purification air conditioning facilities carefully, find out the problems in the air conditioning system in time, so as to deal with them as soon as possible, prevent the failure of the purification air conditioning facilities in the operation process and affect the normal operation. When checking the air conditioning system, it is necessary to check the water quality of the water system to ensure that the water quality meets the relevant requirements, and clean the water filter in time. Especially after winter, because of the temperature, people often use the heat medium water in winter. If there is a problem in the water quality, it will easily form scale, and the scale will settle in the pipeline, which will hinder the smooth operation of the air conditioning system. Therefore, it is necessary to clean the pipeline regularly in winter to prevent scale from blocking the pipeline and restricting the normal operation of the air conditioning system. Sometimes the effect of scale precipitation is very small, sometimes people ignore this problem, so we should carefully deal with various problems in the operation of the system, and make in-depth research, develop a scientific treatment plan, improve the air conditioning purification system, and ensure its normal operation.
In the management and maintenance of the purification equipment in the operating room of the hospital, we can ensure the continuous work of the whole system through scientific planning of heat recovery, scientific selection of hardware parameters, optimization of distribution engineering structure, improvement of the application effectiveness of frequency converter, full use of secondary air return, improvement of the purification system and strengthening of inspection and protection. In addition, during the maintenance period, it is necessary to clean the exhaust air filter, avoid the multiplication of bacteria, properly handle the information of the problems submitted by each department, establish scientific measures for the problems, strictly control each link, reduce the infection rate, and provide better medical services for the patients.
Hospital medical industry is a very large and special industry, especially the hospital operating room has a high requirement for air cleanliness. Design is the basis of purification project quality. To ensure the quality of purification project, the designer must carefully investigate and inspect the construction site of purification project in hospital, otherwise, the quality of purification project designed will be greatly reduced, so the first guarantee for the quality of purification project is designed.
