Can a Split Ductless Air Conditioner be installed without purging the lines afterwards, or fancy hvac tools?

Aug 16, 2006 by x_ped | Posted in Maintenance & Repairs

The mini split ac's come precharged with freon. this allows one to just install the unit, and connect the lines. it states to purge, or evacuate the system after the lines are connected. the only air would be from the actual 15' lines that were connected. will the ac run good without be purged or evacuated? this ductless system is new, and ive heard people installing them without fancy equipment. id like to know if i can get good cooling, without the hvac tools. what do you guys think?

Mini-splits are expensive. You're taking a big gamble here, and it may not work out for you. Mere molecules of water and dirt can cause big problems with the compressor and the metering device for the refrigerant. Why not find someone in the biz, and offer them a few dollars to evacuate the lines and hook up your equipment professionally? If something goes sour, and the lines were not evacuated, you may be hard-pressed to get the manufacturer to honor a warranty claim. Better safe than sorry!

New SplitCool DC18 Unit is Designed for Off-Grid Solar for Commercial and Residential Locations

CHESAPEAKE, Va.–(BUSINESS WIRE)– Solar Panels Plus (SPP), designer and manufacturer of solar water heaters, solar air conditioning/heating systems and photovoltaic solar panels, has released the SplitCool DC18, the world’s first and only DC-powered, high SEER air conditioning system. The SplitCool DC18 is ideal for any commercial or residential location where cooling or heating is required and grid power is unavailable, unreliable or requires generators (with potentially complex or costly refueling logistics).

The SplitCool DC18 runs off a battery bank that is supplied power from an array of photovoltaic panels and installs without ducts, eliminating the majority of installation and materials costs. The unit can be added quickly to an existing structure and eliminates nearly 30 percent of cooling or heating losses which occur in the ductwork of forced air systems. It allows each room to be conditioned as a separate zone. The SplitCool DC18 can be used in permanent and temporary remote buildings or structures, such as construction office trailers, portable classrooms or medical facilities.

“High-efficiency SplitCool DC18 units will dramatically lower the total system cost for running an air conditioner from solar panels, by eliminating the bulk of installation work required by competitive units and by using fewer solar panels and a lower battery requirement,” said John Williams, chief operating officer, Solar Panels Plus. “Unlike the SplitCool DC18, most normal air conditioners simply turn on and off based on the thermostat, and this normal ‘on-off-on-off’ approach is very wasteful of electricity because it is not always necessary to run the compressor at full speed.”

There are other advantages to the SplitCool DC18 versus a traditional window or wall unit including that the remote compressor makes it significantly quieter and does not require a large hole in exterior walls. It also allows an interior room without an exterior wall to be cooled up to 50 feet away. The unit uses four or more 12 volt standard deep cycle batteries.

Ductless Air Conditioning Systems

There are several different kinds of air conditioners on the market today. For instance, a ductless air conditioning system is one that has been around for several years. They are most common in larger homes as you would not need this type of two part system for a smaller home, or just in a single room.

When summer hits you will see a lot of people setting up their small conditioners in windows, or on ledges. An conditioner is a wonderful household appliance that has been around for over 70 years. These incredible inventions do so much more than just keep the house cooled during the hot, steamy days of June, July, and August. When the temperatures get high, the humidity (or the amount of moisture that is in the air) also rises. This makes the heat feel like a sauna. You sweat more. You have a hard time doing activities. And people with respiratory problems can have serious side effects because of it. An conditioner keeps the temperature comfortable, but also decreases the humidity in your home.

Ductless air conditioning systems are a great alternative to small portable air conditioners, and even central air and heating systems. A duct less air conditioner is really a mini split system that has two separate parts connected by tubes of refrigerant. This type of conditioner is great for a smaller home with not a lot of square footage. A ductless system should not be confused with the window type small portable air conditioners. Think of this type of air conditioning system like what you would see in a hotel room or school building.

The main system is the part that sits outside the wall. This unit houses the condensers and refrigeration where the air is cooled through the fins and the blower. It sits on the ground in a level area. Connected to this part of the system is the part that looks like thru the wall air conditioners. They can sit on a window, but they are much better situated through the wall itself. They have more stability and are not to be moved after they are installed.
