摘　　要：为提高变频空调器能效及安全稳定性，就硅膨胀阀在变频空调器中的应用展开了研究。对硅膨胀阀流量特性的实验表明在最大流量的20％～70％范围内，其流量与占空比之间线性特性较好，其正向流动和反向流动的流量特性重合度高，响应特性线性好。同时对其在KFR-25GW/Bp变频空调器中进行性能实验，实验表明相对电子膨胀阀而言，其变频空调器的制冷量、制热量以及相应的能效比更高。因而，硅膨胀阀可以作为变频空调器节流元件。This article study the application of the MEMS silicon -expansion valve to improve the EER and the sys-tem stability of the invertor air -conditioners.Test on the flow characteristics of the MEMS silicon -expansion valve indicate that the linearity between the flow and the duty cycle is better within the range of 20 to 70 percent of it＇s maximum flow, the contact ratio of the forward flow and reverse flow is higher , and the response characteristics is better.Performance test on the KFR-25GW/Bp inverter air conditioner indicate that when using the MEMS silicon-expansion valve the cooling and heating capacity , and the EER are higher than when using the electronic expan-sion valve.So the the MEMS silicon-expansion valve can be used as the throttle element of the inverter air condi-tioners.
