<p><span style="font-size:16px;"><span style="font-family:宋体;"> 直热式的优点：</span></span></p>
<p><span style="font-size:16px;"><span style="font-family:宋体;"> 1.冷凝工况稳定<br>
不管水温和环境温度如何变化，当直热式的出水温度恒定时，其冷凝压力和冷凝温度是基本恒定的。我们可以利用这一特点用冷凝压力调节阀来控制水温。相对于循环式，直热式在冷凝这一侧，至少工况是稳定的。这一点，对于延长压缩机的工作寿命非常关键，对热泵的结霜速度也影响很大。</span></span></p>
