4mm管换热器降低制冷剂充注量实验研究

Experimental studies on reducing refrigerant charging quantity in heat exchanger with 4mm diameter tubes

本文利用最新研发的4mm管换热器分别对分体机进行充注R410A、R290的性能实验。实验结果表明:采用4mm管换热器,在保持性能不变的情况下,不仅可以有效的降低换热器体积和成本,也能明显降低制冷剂充注量。

investigated. cost, but also Based on the new 4mm tube - fin heat exchanger, three air -conditioners using R410A and 11290 were The experimental results showed that 4mm tube - fin heat exchanger not only can reduce its volume and can obviously reduce refrigerant charging quantity.
