医用氧舱空调控制器的设计及应用

目的：设计一种氧舱空调控制器,实现定时排水,使制热过程中内风机延迟工作,避免空调开始工作时吹凉风。方法：该设计过程利用空调的内、外风机及三通电磁阀,通过与交流接触器及微处理器的相互连接,以及继电器与微处理器的连接来实现,并利用继电器将高电压与氧舱隔离,使空调能够在氧舱内使用。结果：微处理器对空调的运行状态进行检测,实现了定时排水,制热过程中内风机延迟工作,达到了预期的目的。结论：本实用新型专利的设计,实现了自动定时排水,制热延时启动的功能,避免了空调开始工作时吹凉风,效果良好,值得推广。

Design and application of air controller for medical oxygen tank

Objective： The new utility model patents is to design a kind of oxygen tank,air controller that can achieve timing drainage,make the heating process of fan to avoid delay in air conditioning started cool wind blow.Methods： The design process of the use of air conditioning,within the fan and the 3-way magnet valve,through its and ac contactor and microprocessor connected,and relays and microprocessor connected to the implementation,and relay use will high voltage and oxygen tank,air conditioning in isolation to use oxygen cabin.Results： Microprocessor to air conditioning operation state for testing,realize the timing drainage,in the process of heating in fan delay work,achieve the expected purpose.Conclusion： The new utility model patent design,has realized automatic timing drainage,heating time delay activated function,avoid the air conditioning when he began to work,good effect and blow cool wind is worth extending.
