<p style="margin: 16px 0px; padding: 0px; max-width: 100%; box-sizing: border-box; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", Arial, sans-serif; font-size: 16px; line-height: 25.6px; widows: 1; -webkit-tap-highlight-color: transparent; word-wrap: break-word !important;"><span style="font-family:宋体;"><span style="font-size:16px;">（1）关式系统</span></span></p>
<p style="margin: 16px 0px; padding: 0px; max-width: 100%; box-sizing: border-box; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", Arial, sans-serif; font-size: 16px; line-height: 25.6px; widows: 1; -webkit-tap-highlight-color: transparent; word-wrap: break-word !important;"><span style="font-family:宋体;"><span style="font-size:16px;">就是循环管路中的水在循环过程中始终不与大气接触，在系陀鸹膨胀罐；也可在系统最高点设膨胀水箱，当系统水加热时体积会膨胀，以至系统可能会爆炸，因而，设膨胀罐或是设膨胀水箱，使系统胀出来的热水挤进膨胀罐或膨胀水箱中，所有的关式供暖系统中都必要装置相应的设备(膨胀罐或膨胀水箱)包容水在加热时增大的体积 ？掌慈缺霉┡低持，通过装置膨胀罐或膨胀水箱来包容加热时的膨胀水量，同时还拥有恒定系统压力的作用 。</span></span></p>
<p style="margin: 16px 0px; padding: 0px; max-width: 100%; box-sizing: border-box; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", Arial, sans-serif; font-size: 16px; line-height: 25.6px; widows: 1; -webkit-tap-highlight-color: transparent; word-wrap: break-word !important;"><span style="font-family:宋体;"><span style="font-size:16px;">（2）开式系统</span></span></p>
<p style="margin: 16px 0px; padding: 0px; max-width: 100%; box-sizing: border-box; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", Arial, sans-serif; font-size: 16px; line-height: 25.6px; widows: 1; -webkit-tap-highlight-color: transparent; word-wrap: break-word !important;"><span style="font-family:宋体;"><span style="font-size:16px;">开式系统也称为无压系统，也就是供热系统循环管路中的循环水，在流经某个地位时与大气接触，如开口的蓄热水箱及膨胀水箱等 。膨胀水箱不只能赔偿系统热水加热时膨胀的体积，还能兼作开式系统起到补水作用 。</span></span></p>
<p style="margin: 16px 0px; padding: 0px; max-width: 100%; box-sizing: border-box; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", Arial, sans-serif; font-size: 16px; line-height: 25.6px; widows: 1; -webkit-tap-highlight-color: transparent; word-wrap: break-word !important;"><span style="font-family:宋体;"><span style="font-size:16px;">（3）关式与开式系统优弊端</span></span></p>
<p style="margin: 16px 0px; padding: 0px; max-width: 100%; box-sizing: border-box; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", Arial, sans-serif; font-size: 16px; line-height: 25.6px; widows: 1; -webkit-tap-highlight-color: transparent; word-wrap: break-word !important;"><span style="font-family:宋体;"><span style="font-size:16px;">开式系统与大气连通，系统水质易传染；系统水进入空气增长含氧量，系统水中含氧量过高容易对结尾散热器内壁产生侵蚀；另表，开式系统配置的循环泵比关式系统配置的循环泵扬程要大，相对来说开式系统配置的循环泵的电机用电量比关式系统配置的循环泵的电机用电量要大，开式系统比关式系统年运行用度要高 。</span></span></p>
<p style="margin: 16px 0px; padding: 0px; max-width: 100%; box-sizing: border-box; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", Arial, sans-serif; font-size: 16px; line-height: 25.6px; widows: 1; -webkit-tap-highlight-color: transparent; word-wrap: break-word !important;"><span style="font-family:宋体;"><span style="font-size:16px;"><span style="margin: 0px; padding: 0px; max-width: 100%; box-sizing: border-box; word-wrap: break-word !important; -webkit-tap-highlight-color: transparent; font-weight: 700;">14、重要热泵品牌产品介绍</span></span></span></p>
<p style="margin: 16px 0px; padding: 0px; max-width: 100%; box-sizing: border-box; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", Arial, sans-serif; font-size: 16px; line-height: 25.6px; widows: 1; -webkit-tap-highlight-color: transparent; word-wrap: break-word !important;"><span style="font-family:宋体;"><span style="font-size:16px;">目前凭据国标得知：低温空气源热泵侧沉于热泵采暖；风冷冷水（热泵）机组侧沉于造冷，作用相当于空调；空气源热泵热水机侧沉于提供生涯热水，从以上三种分歧的产品不难区别它们使用的职能 。但是，要知路出产以上产品的厂家就极度难以分清了 。</span></span></p>
<p style="margin: 16px 0px; padding: 0px; max-width: 100%; box-sizing: border-box; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", Arial, sans-serif; font-size: 16px; line-height: 25.6px; widows: 1; -webkit-tap-highlight-color: transparent; word-wrap: break-word !important;"><span style="font-family:宋体;"><span style="font-size:16px;">空气源热泵品牌和厂商重要有两类，一类是专门从事热泵研发与造作的厂商；另一类是传统空调设备厂家 。目前，综合以上两类空气源热泵品牌已经超过300家 。</span></span></p>
<p style="margin: 16px 0px; padding: 0px; max-width: 100%; box-sizing: border-box; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: "Helvetica Neue", Helvetica, "Hiragino Sans GB", "Microsoft YaHei", Arial, sans-serif; font-size: 16px; line-height: 25.6px; widows: 1; -webkit-tap-highlight-color: transparent; word-wrap: break-word !important;"><span style="font-family:宋体;"><span style="font-size:16px;">除此之表，空气源热泵热水机与空气源热泵供暖及造冷有很大的差距 。
