Well, the past couple of weeks have seen a slew of air conditioner service- starting with a simply check out of a new (used) rig.好，过去几个星期所看到的一系列的空调服务一开始用简单地检查出一个新的（用）钻机。

On this rig (1995, or 11 years old), everything checked out fine- standard cleaning of the LP appliances, testing 120 volt and 12 volt systems, leak testing the LP system, etc. Then I get up to the air conditioner.在此钻机（ 1995年，或11岁） ，一切都签出的罚款标准的清洁工作在低压电器，测试120伏特和12伏特系统，泄漏测试低压系统等的话，我得到最多的空调。 One glance at the filters, and I figured it would be a candidate for a good cleaning, and I was right.一看过滤器，我想通这将是一个候选人有一个良好的清洁，而我是正确的。

On most rooftop air conditioners, you can see the inside (evaporator) coils by looking up through the air return- some models are easier than others, though.对大多数的天台，冷气机，您可以看到内（蒸发器）线圈所期待透过空气的回报，有些模型比其他人更容易，虽然。 This was a Coleman Mach series, so I could just see the coils, but could not access them for a good cleaning, so a trip to the roof was in store.这是一个科尔曼马赫系列，所以我可以看到线圈，但无法存取他们有一个良好的清洁，因此，此行至屋顶是在商店。

Getting access to the evaporator coils is not very difficult, you do have to remove the plastic shroud, and then some sheet metal on the front-进入蒸发器的线圈也并不是很困难的，你必须删除塑胶裹尸布，然后一些金属板材上前线

This is an exploded view of a DuoTherm BriskAir, but standard Coleman units are pretty much the same.这是一个发生爆炸，鉴于有duotherm briskair ，但标准科尔曼单位是相当一致的。 A tip- when removing the screws that hold the sheet metal cover on, pay attention to the screws- there will usually be a few that have a blunt end on them, these are meant to usually go in to the electrical compartments, or where there are wires or tubing.举报时，删除螺丝举行钣金封面上，要注意螺丝-有通常会在数有钝结束对他们的，这些都是意思通常在向电气舱，或有是电线或油管。 You do not want to find out you put a sharp pointed screw back where it was not used originally.你不想找出你提出一个尖锐的指出，螺杆回，而没有使用原来的。

Once you have the sheet metal cover off, I use a stiff bristle brush to “comb” any large lint off of the fins.一旦你有金属薄板涵盖小康，我使用激烈的刚毛一刀切“梳”任何大林特小康的鳍。 Once the “big stuff” is gone, I use a good degreaser- I use VoomRV, because it is PH neutral and a great degreaser, Coleman recommends “Formula 409″.一旦“大东西”是走了，我用一个良好的除油-我使用voomrv ，因为它是pH值中性的一个伟大的脱脂剂， 科尔曼建议“的公式409 ” 。 I tend to shy away from most commercial A/C coil cleaners as they are often very harsh on aluminum- they clean the aluminum coils well, but I don’t want the cleaner running down the side of the RV (something you don’t have to worry about in home units).我倾向于回避大多数商业/中线圈的清洁工人，因为他们往往很苛刻，对铝，他们干净的铝线圈好，但我不想清洁的运行下来，一边的的RV （东西你不有担心在首页单位） 。

I soak the coils well, then lay heavy towels over the air intake to catch any water (I put towels inside as well- just in case), then spray the coils off. i浸泡线圈好，然后奠定沉重的毛巾超过进气口要赶上任何水（我把毛巾内，以及只要在案件） ，然后喷雾线圈小康。

This is a good time to check the drain holes for the condensation- there will be holes in the bottom pan on either side of the tray the coils sit in. It’s easy to clean them out.这是一个很好的时间来检查排水孔为凝结-会有漏洞，潘底部两侧的托盘线圈坐在英寸，它的清洁更容易出来。 It’s also a good idea to check the gasket-它也是个不错的主意，检查垫片-
make sure the bottom of the unit is at least 1/2″ above the roof -确认底部的单位至少是1 / 2 “以上的世界屋脊-

It is also a very good idea to check and clean the outside, or condenser coils.这也是一个很好的构思，检查及清洁外，或冷凝器线圈。 Sometimes they will be very clogged- as in the case from Dudes RV Air Conditioner page , but sometimes they might still look clean.他们有时会很堵塞-的情况一样，从dudes的RV 空调器页 ，但有时却可能仍看清洁。 Even if they do look clean- clean them any way !即使他们看看清洁干净，他们以任何方式 ！ In air conditioners that have not been cleaned for a couple of years- and the unit has been used- I will consistently measure a 2 amp drop in current - just from cleaning.在冷气机有没有得到清理，为一对夫妇年和单位已使用-我会一贯衡量一个2安培下降，在目前的-刚刚从清洁。 You will be amazed at the dirt which will come out of a clean looking coil.您一定会感到惊讶，在污垢会出来一个清洁的展望线圈。

While you are up on the roof with the shroud off, it is also a good time to check the fan motor- some units have oil ports- if yours does, put a few drops of electric motor oil in each port.当您了在屋顶上与裹尸布小康，这也是一个很好的时间来检查风扇电机-一些单位的石油港口-如果你不付诸表决，几滴油电机在每个港口。 You can also check the condenser blade.您也可以检查冷凝器叶片。 Another unit I serviced ( a DuoTherm ) had a fan blade that was starting to go- it was cracking around the shaft attachment, which made it just a little of balance- to the point where it would hit the sheet metal every now and then.另一个单位， i服务（ 1 duotherm ）有一个风扇叶片，这是出发去-这是打击周围轴实习，这使得它只是一个小平衡，以点，它将击中金属板材每一个现在，然后。

DuoTherm has redesigned the blade- the old models were 4 blade, the new ones have 6 blades and a much stronger center structure. duotherm重新设计了叶片的旧模式，分别为4叶片，新的有6个刀片和更强有力的中心结构。 They are very inexpensive, and used on nearly every BriskAir model.他们是非常便宜，和使用的几乎每一个briskair模型。 The part number is 3107914008 and if your local RV parts place does not have it, you can always order it from DTI RV Parts .部分号码是3107914008 ，如果您当地的RV部分地方没有它，您可以随时定购从dti的RV部分 。

I’ve got to say- RV roof top air conditioners are about the most reliable component on an RV, but they do need regular maintenance.我已经到了讲的RV屋顶上方，冷气机是有关最可靠的成分对一的RV ，但他们确实需要进行定期维修工程。 As with most things I talk about, given regular maintenance, they will give years of service.与大多数的东西，我谈到，由于定期维修，他们将提供的服务年资。 Often RV air conditioners are replaced simply to add new features and lower current draw, not because there is really anything wrong with them.往往是风疹病毒，冷气机所取代，只不过是添加新功能和较低的电流借鉴，这并不是因为实在是不妥与他们。
