<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-size:16px;"><span style="font-family:宋体;">选择冷暖一体机是为了一机两用，冬季采暖、夏季造冷。北京及周边地域村落住房选择热泵装机容量时以采暖为主选择容量即可（除非对造冷有特殊需要）。</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-size:16px;"><span style="font-family:宋体;">以北京地域为例，空气源热泵供暖时，在-7.6℃时的造热功率与造冷尺度工况时的造冷功率根基一样。村落住房采暖热负荷无数都在70W/㎡左右，因而满足造热时配置的热泵，造冷时功率也是70W/㎡。另表，采暖时通常是整个构筑都要供热，而造冷时多是部门选取，因而满足采暖需要的根基都能满足造冷需要。</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-size:16px;"><span style="font-family:宋体;">对于户式空气源热泵来说，变频机相对于定频机优势显著。对用户来说，两种机型价值相差不大时，优选变频机。变频机优势重要体此刻以下几点：</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-size:16px;"><span style="font-family:宋体;">（1）空气源热泵都拥有随着环境温度降低造热功率衰减的特点。变频机可在极端气象时超频运行，可有效降低造热功率的衰减幅度。</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-size:16px;"><span style="font-family:宋体;">（2）室内温度（或循环水的回水温度）设定好后，定频机是通过自动启动或终场压缩机来实现室内温度的恒定，而变频机是通过节造电源频率来维持或降低压缩机转速来实现，从而有效降低了压缩机的启停次数，对提高空气源热泵能效比及耽搁压缩机使用寿命都是有益的。</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-size:16px;"><span style="font-family:宋体;">压缩机是按肯定的系列出产的，每个系列有特定的型号。若是都做成单压机热泵，就会使热泵型号过于单一，无法满足各类大幼分歧的构筑必要。为满足分歧构筑面积采暖的必要，热泵企业就会通过双压机配置的大局来丰硕热泵产品的型号和类别。大型的空气源热泵还有4压机或8压机等。</span></span></p>
