<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、夏季制冷。北京及周边地区农村住房选择热泵装机容量时以采暖为主选择容量即可（除非对制冷有特殊需求）。</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;">以北京地区为例，空气源热泵供暖时，在-7.6℃时的制热功率与制冷标准工况时的制冷功率基本相同。农村住房采暖热负荷多数都在70W/㎡左右，因此满足制热时配置的热泵，制冷时功率也是70W/㎡。另外，采暖时一般是整个建筑都要供热，而制冷时多是局部采用，因此满足采暖需求的基本都能满足制冷需求。</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明显。对用户来说，两种机型价格相差不大时，优选变频机。变频机优势主要体现在以下几点：</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）空气源热泵都具有随着环境温度降低制热功率衰减的特点。变频机可在极端天气时超频运行，可有效降低制热功率的衰减幅度。</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停止压缩机来实现室内温度的恒定，而变频机是通过控制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延长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;">压缩机是按一定的系列生产的，每个系列有特定的型号。如果都做成单压机热泵，就会使热泵型号过于单一，无法满足各种大小不同的建筑需要。为满足不同建筑面积采暖的需要，热泵企业就会通过双压机配置的形式来丰富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>
<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;">同一款压缩机，双压机热泵制热量是单压机热泵制热量的2倍，但是价格要比两台单压机热泵便宜，体积要比两台单压机热泵小，安装维护起来都比两台要方便。对于用户来说，满足自己建筑采暖需要即可，无需过多纠结是单压机还是双压机。</span></span></p>
