| 摘 要： | 热力膨胀阀的感温包是影响膨胀阀性能的主要因素之一,制冷系统常常因为回气温度不稳定导致的温包压力波动而造成振荡,影响系统的稳定运行.在R410A热力膨胀阀的感温包内加入吸附填充物,对带填充物温包的温度压力特性进行了研究,发现温包填充物有效增大了升温压力变化的时间常数,而且温包填充尺寸决定了感温包的工作温度区间,并在家用空调上使用带不同感温包的热力膨胀阀进行了系统实验,发现温包充填物的改进可以减小系统的振荡.

| Abstract: | Charging characteristic of TEV temperature sensing bulb is one of the most affective factors of TEV performance.Refrigeration systems are often unstable because of bulb pressure fluctuations caused by oscillation of back air temperature of compressor.Temperature and pressure characteristics of TEV bulb with adsorption filler in R410a system was studied.It was found that adsorption filler increase the time constant of pressure change caused by bulb temperature rising and the dimension of adsorption filler de... |
