求助大金多联机制热差

/pstatus" 本帖最后由 雅马哈150 于 2019-1-17 11:24 编辑 /ibr /br /   大金多联机制热效果很差，气温5度，外机回气管路及气液分离器接霜严重，此机为变频空调，，低压0.7MPA左右，外机冷凝器没有一点霜，也不冷，外机有3个压缩机工作，2个电子膨胀阀，其中有一个发现不正常，一端有霜，另外一端没有霜，把2个膨胀阀的插头互换一下，还是左边一个没有什么反应。请大神看看是不是左边的电子膨胀阀问题？因多联机很少接触，所以不是很懂，请指点谢谢！还有如果是阀坏了大伙一般报价多少？单位的。ignore_js_opstyle.guestviewthumb {margin:10px auto; text-align:center;}.guestviewthumb a {font-size:12px;}.guestviewthumb_cur {cursor:url(static/image/common/scf.cur), default; max-width:100px;}.ie6 .guestviewthumb_cur { width:100px !important;}/styleguestviewthumb"margin: 0 auto;"a class="guestviewthumb_cur" aid="710539" src="https://www.jdwx.info/static/image/common/none.gif" onerror="javascript:if(this.getAttribute('makefile')){this.src=this.getAttribute('makefile'); this.removeAttribute('makefile');}" file="https://www.ysyk.info/data/attachment/image/000/71/05/39_100_100.jpg" makefile="forum.php?mod=image&aid=710539&size=100x100&key=2d8c5f3686ff7aff&type=1" inpost="1" alt="左边一个下端没有霜" title="左边一个下端没有霜"/bra href="member.php?mod=logging&action=login" 登录/注册后可看大图/a/tip tip_4 a id="a style="position: absolute; display: none" disautofocus="true"xs0"pstrong1.jpg/strong em class="xg1"(139.53 KB, 下载次数: 0)/em/ppa href="page-710539.html" target="_blank"下载附件/a a href="javascript:;" id="savephoto_710539" url="home.php?mod=spacecp&ac=album&op=saveforumphoto&aid=710539&handlekey=savephoto_710539"保存到相册/a/pp左边一个下端没有霜/pp class="xg1 y"span title="2019-1-17 11:10"昨天 11:10/span 上传/p/guestviewthumb"margin: 0 auto;"a class="guestviewthumb_cur" aid="710540" src="https://www.jdwx.info/static/image/common/none.gif" onerror="javascript:if(this.getAttribute('makefile')){this.src=this.getAttribute('makefile'); this.removeAttribute('makefile');}" file="https://www.ysyk.info/data/attachment/image/000/71/05/40_100_100.jpg" makefile="forum.php?mod=image&aid=710540&size=100x100&key=a6e646b484317bc3&type=1" inpost="1" alt="汽液分离器接霜严重" title="汽液分离器接霜严重"/bra href="member.php?mod=logging&action=login" 登录/注册后可看大图/a/tip tip_4 a id="a style="position: absolute; display: none" disautofocus="true"xs0"pstrong3.jpg/strong em class="xg1"(149.04 KB, 下载次数: 0)/em/ppa href="page-710540.html" target="_blank"下载附件/a a href="javascript:;" id="savephoto_710540" url="home.php?mod=spacecp&ac=album&op=saveforumphoto&aid=710540&handlekey=savephoto_710540"保存到相册/a/pp汽液分离器接霜严重/pp class="xg1 y"span title="2019-1-17 11:10"昨天 11:10/span 上传/p/guestviewthumb"margin: 0 auto;"a class="guestviewthumb_cur" aid="710541" src="https://www.jdwx.info/static/image/common/none.gif" onerror="javascript:if(this.getAttribute('makefile')){this.src=this.getAttribute('makefile'); this.removeAttribute('makefile');}" file="https://www.ysyk.info/data/attachment/image/000/71/05/41_100_100.jpg" makefile="forum.php?mod=image&aid=710541&size=100x100&key=d42feefe8d0b7d32&type=1" inpost="1" alt="怀疑这个膨胀阀问题" title="怀疑这个膨胀阀问题"/bra href="member.php?mod=logging&action=login" 登录/注册后可看大图/a/tip tip_4 a id="a style="position: absolute; display: none" disautofocus="true"xs0"pstrong4.jpg/strong em class="xg1"(131 KB, 下载次数: 0)/em/ppa href="page-710541.html" target="_blank"下载附件/a a href="javascript:;" id="savephoto_710541" url="home.php?mod=spacecp&ac=album&op=saveforumphoto&aid=710541&handlekey=savephoto_710541"保存到相册/a/pp怀疑这个膨胀阀问题/pp class="xg1 y"span title="2019-1-17 11:10"昨天 11:10/span 上传/p/guestviewthumb"margin: 0 auto;"a class="guestviewthumb_cur" aid="710542" src="https://www.jdwx.info/static/image/common/none.gif" onerror="javascript:if(this.getAttribute('makefile')){this.src=this.getAttribute('makefile'); this.removeAttribute('makefile');}" file="https://www.ysyk.info/data/attachment/image/000/71/05/42_100_100.jpg" makefile="forum.php?mod=image&aid=710542&size=100x100&key=f6240a35b22af3c2&type=1" inpost="1" alt="结霜严重" title="结霜严重"/bra href="member.php?mod=logging&action=login" 登录/注册后可看大图/a/tip tip_4 a id="a style="position: absolute; display: none" disautofocus="true"xs0"pstrong22.jpg/strong em class="xg1"(141 KB, 下载次数: 0)/em/ppa href="page-710542.html" target="_blank"下载附件/a a href="javascript:;" id="savephoto_710542" url="home.php?mod=spacecp&ac=album&op=saveforumphoto&aid=710542&handlekey=savephoto_710542"保存到相册/a/pp结霜严重/pp class="xg1 y"span title="2019-1-17 11:10"昨天 11:10/span 上传/p/div/div/ignore_js_op
