电磁四通换向阀的容量是与热泵型制冷设备匹配的主要依据,直接影响制冷量和系统能效比。通过测试流经四通阀的空气流量,利用相似原理推算流经四通阀的制冷剂流量,并与容量实验数据对比,结果表明流量测算值与实验值平均偏差为4.4%,空气流量法可以快速并较准确地测算四通阀的容量。
The capacity of the electromagnetic four-way reversing valve is the main basis for matching with the heat pump type refrigeration equipment, which directly affects the cooling capacity and system energy efficiency ratio. By testing the air flow through the four-way valve, the refrigerant flow through the four-way valve was estimated using a similar principle and compared with the capacity experimental data. The results showed that the average deviation between calculated and experimental values was 4.4%. The air flow method Calculate the capacity of the four-way valve quickly and accurately.
