Medical positron emission tomography (PET)-computed tomography (CT) direct-current air-cooled air conditioner and working method thereof

Abstract

The invention discloses a medical positron emission tomography (PET)-computed tomography (CT) direct-current air-cooled air conditioner. The medical PET-CT direct-current air-cooled air conditioner comprises a cabinet, a compressor, an evaporator, a condenser, an expansion valve, a PET ring, a thermal bulb, an evaporation fan, a condensation fan, a power box, a control system and a remote control unit, wherein the thermal bulb is composed of a return air temperature sensor, an outlet air temperature sensor and an environment temperature sensor. According to the medical PET-CT direct-current air-cooled air conditioner, a closed circulation system is formed by connecting the compressor, the evaporator, the condenser and the expansion valve through copper pipes, heat exchange is conducted on the evaporator and the condenser through the evaporation fan and the condensation fan, and operation of the whole system is controlled through the multifunctional control system, so that air in the PET ring circularly flows along with operation of the evaporation fan so as to cool a heating module in the PET ring, normal operation of the PET ring can be guaranteed effectively, the situation that the internal temperature is excessively high and consequently a short circuit is caused or electrical apparatus elements are burned out is avoided, and the PET ring is also protected well.

Description

Technical field [0001] The invention relates to the field of air conditioners, in particular to a medical PET-CT direct current air-cooled air conditioner and a working method thereof. Background technique [0002] With the rapid development of society and economy, people’s living conditions and standards are getting higher and higher, and there are more and more requirements for the quality of life. People’s lives and work are gradually modernized, and air conditioners have become people. Electrical products necessary in life. Hospitals are public labor centers, usually in densely populated places, so both ventilation and temperature are relatively poor. At the same time, due to the use of various instruments and equipment in the hospital will emit a lot of heat, which will make the indoor temperature High, in order to ensure normal ventilation and suitable temperature, and to ensure that various medical devices can be used normally, they must be adjusted by air conditioning. ...

AI Technical Summary

Problems solved by technology

From the above content, it can be seen that it plays a very important role in the medical field. However, due to its large workload, various parts inside it emit a lot of heat during the work process, which will cause the temperature in the entire device to be too high. If it is too high, it will cause a short circuit in the equipment if it is light, and it will cause its internal components to burn out. However, no matter what kind of failure occurs, it will delay the normal examination of many patients, and will cause a lot of damage to both the hospital and the patient. Inconvenient, so in order to ensure that PET-CT can work normally, it is necessary to ensure that its internal cooling system can work normally
