Think of the A/C system operating in a continuous loop that is split into a high-pressure side and low-pressure side at the compressor. Once the compressor clutch engages (suction and discharge cycle), it compresses the low-pressure refrigerant gas into a high-pressure gas. The high-pressure gas flows out of the compressor into the condenser, which is usually located in front of the radiator. The purpose and function of the condenser is similar to the cooling system radiator, which removes heat from the high-pressure gas. Inside the condenser, the high-pressure gas changes (condenses) to form a high pressure liquid as the heat from the refrigerant is released to the air. The still-highly-pressurized liquid then flows into the receiver-drier, which contains a filter to remove any debris within the system as well as any moisture or impurities from the refrigerant. Any moisture combined with refrigerant can form a corrosive acid harmful to the system. The purified liquid refrigerant flows through the A/C hoses into the cabin of the car, where it travels through a small orifice called the thermal expansion valve.

When the high pressure of the liquid drops, it causes the refrigerant to vaporize. The resulting fine mist is metered by the valve and flows into the evaporator located inside the heater box under the dash. harga ac indoor bekasThe drop in pressure caused by the expansion valve or metering valve causes the refrigerant to vaporize as it moves into the evaporator, which absorbs heat in the process.sanyo hvac unit Air is blown through the evaporator by a blower motor which is also located inside the heater box. 5000 btu window air conditioner reviewsThe air is then cooled as the heat is removed and transferred to the refrigerant and cool air travels into the passenger compartment. When assembling or installing an air conditioning system on a hot rod or other specialty vehicle, you'll want to familiarize yourself with the key components and their functions.

Shop Window Air Conditioners A casement air conditioning unit is designed specifically for windows that swing out to the side (usually with a hand crank) or slide open sideways. Shop Casement Air Conditioners Intended for rooms with windows that cannot accommodate mounting a full AC unit, or for those who want the ability to move the AC unit from room to room.

A portable air conditioner is placed on the floor and uses a flexible hose to vent hot air outside. The venting hose can usually fit through a small space, such as the center vent often found in basement glass-block windows. Shop Portable Air Conditioners These are installed through the wall of a building in a designated opening. Wall Air Conditioners require a sleeve in order to be properly installed.

Shop Central Air Conditioning SystemsIn the sweltering heat of summer, there's nothing more frustrating than trying to install a portable air conditioner in a casement or crank window.

The window kit that comes with most portable air conditioners is designed to be installed with a traditional sliding window, but that doesn't mean you can't enjoy the clean look of a crank window and the cool comfort your new portable air conditioner provides. The easiest way to vent your portable air conditioner with a casing or crank windows is to fabricate an insert to fit into the window. This way you can keep the cool air in and keep the hot summer air out.Things to Keep in Mind:Be sure to plan out the details for cutting or drilling before you get to the hardware store. Many portable air conditioner manufacturer's recommend that the air conditioning unit be placed as close as possible to the installation site, so that the venting hose doesn't need to be extended. This is especially important to think about before you drill a hole in the Plexiglas or Styrofoam. An inch one way or the other may impact whether or not the hose can reach the hole that's been drilled. Now that you've brought your new insert home, it's time to install it in your window.

To do this, open your crank window and hold it in place with a latch. By attaching the latch to the widow and window frame, you're helping prevent possible damage to the open window. Make sure the widow is reasonably secure and won't get damaged if there is a breeze or light wind. Next, you need to secure the insert to the window frame. There are several ways to do this. One idea is to use twist clamps to secure the insert. If you know you're going to use Plexiglas, another idea is to use retainer clips (like on the back of a picture frame) to hold the Styrofoam or Plexiglas in place. Since your insert is the only thing that divides your home from the outdoors, it's important to seal it and make sure that it's reasonably weatherproof. To do this you can caulk where the window frame and casing meets. Another option is to use self-adhesive weather stripping. You should be able to find these tools at your local hardware store or at larger home improvement stores. If you're going to use self-adhesive weather stripping, you may want to attach it to the insert before you secure the insert to the window frame.

One thing you'll want to keep in mind is that the weather stripping should fit tightly between the window frame and the insert so that it forms an effective seal. The weather stripping should have enough pressure on it so that it compresses and is about half of its normal thickness where the window frame and insert meet. Making sure the weather stripping fits snugly is key to weatherproofing your insert. Another weatherproofing option is to simply run the weatherproof stripping along the area where the window frame and insert meet. To make extra sure the window is as weatherproof as possible, you can fit the weather proof stripping between the wall and insert and also run it over the area where they meet. If you use this method, you can help ensure that your insert is as weather proof as you can possibly make it. Now that you've fabricated your insert, installed it and made sure it's weatherproof, it's time to set up your portable air conditioner. The last step is attaching the hose to your insert.
