Abstract
Description
はじめに、冷凍サイクル装置としての空気調和装置の全体の構成(冷媒回路)について説明する。図1に示すように、空気調和装置1は、圧縮機3、室内熱交換器5、室内ファン7、絞り装置9、室外熱交換器11、室外ファン21、四方弁23および制御部51を備えている。圧縮機3、室内熱交換器5、絞り装置9、室外熱交換器11および四方弁23が、冷媒配管によって繋がっている。
熱抵抗の値が小さくなることでAU値は高くなり、熱交換性能は向上する。たとえば、伝熱管外の熱抵抗Roを小さくするには、伝熱管外の伝熱面積を増加するか、伝熱管外の流体の流速を上げるか、または、伝熱管外の熱伝達率を向上させる機構を備えている必要がある。また、伝熱管内の熱抵抗Riを小さくするには、伝熱管内の蒸発熱伝達率αiを上げるか、または、伝熱管内の伝熱面積を大きくする必要がある。
実施の形態2に係る室外ユニットの室外熱交換器について説明する。図14に示すように、室外熱交換器11は、主熱交換部13(第2熱交換部)と補助熱交換部15(第1熱交換部)とを備えている。主熱交換部13では、冷媒パス群14a、14b、14c、14d(第2冷媒パス)が形成されている。補助熱交換部15では、冷媒パス16a、16b、16c、16d(第1冷媒パス)が形成されている。
