Checking the air conditioning (AC) compressor is an important step in troubleshooting any issues with your car's air conditioning system. Here are some steps you can take to check the AC compressor:
Visual Inspection:
Start by visually inspecting the AC compressor. Look for any signs of damage, such as oil leaks, loose or damaged belts, or physical damage to the compressor itself.
Belt Tension:
Check the tension of the AC compressor belt. A loose or damaged belt can affect the compressor's performance. Ensure that the belt has the right amount of tension and is not cracked or frayed. learn more
It is an alternative to mostly banned CFCs (most infamous of which is R22), and to be phased out in the future HFCs (R410a, R134 and similar). That being said the general consensus is that R600a (isobutane) requires compressors/systems specifically designed for it. The most suitable HC or natural refrigerant substitute for R22 is R290, which although shunned by the industry will perfectly replace it with an efficiency increase of about 20% without any retrofitting or other adjustments.

Flora is normally defined as the plant or vegetation life in a specific region or period of time.
The target temperature is 20*. It can vary from that based on conditions, but that is the design.

The target temperature is 20* difference between the return and the supply air temperature. It can vary from that based on conditions, but that is the design.

First off, the refrigerant is not Freon, it is R134. If it needs refrigerant, then you have a leak. It is illegal to add refrigerant to a system without repairing the leak. You also more than likely do not have the specialized tools necessary to repair or to charge the system correctly. Take it to a professional.
Year? Just a brief suggestion, it will be difficult to find Freon and if you do, it is expensive. The newer refrigerant, 134a, is much more readily available and far cheaper. In general, connect your charging aparatus (whichever type you have) to the LOW side of the refrigeration system. Two lines lead from the compressor. One goes to the condenser (the radiator looking coil that's in front of the regular radiator) and the other line goes to the receiver/dryer. The line that goes to the receiver/dryer is the low pressure side. There should be a port somewhere near the receiver/dryer, that's where you connect to add refrigerant. You'll need a gauge to know when to stop, and you may need to jumper the low pressure switch that is on the side of the receiver/dryer, otherwise it will take forever to get enough refrigerant to start getting the system to pump.
Number one rule with refrigerant is, "If you have to add it, you have a leak." Auto refrigerant is sold in pressurized cans and, to my knowledge, requires certification to purchase and use. There will be a port with a cap on the line coming out of the top of the compressor. Screwing the can on will fill it, but overcharging will reduce the cooling power of the refrigerant.
You can buy it at any auto store. Even Walmart carries it. No need for a cert.
you buy the adapter hose and put it on the low pressure valve and start to fill the unit.
Connect a freon tank and gauge to the low side AC port. Start the engine and turn the AC on high. Open the freon valve. When the gauge reads full torn the valve off and unhook the gauge and tank.
Freon is added to a 1990 240sx by connecting a Freon source to the low pressure side of the system and allowing it to pull in Freon. This is done with the vehicle running and the air conditioner blowing.
If older then 95, it runs r12 refrigerant, and you need to have a pro use a recapture machine for the newer formula conversion. If 95 or newer, simply remove the low pressure line cap, plug on your 134 refrigerant w oil can, and fill with vehicle running and AC on. Do not over fill, most these DIY kits have a gauge, so keep it in the green.
Remove the belt from your 1999 Dodge Grand Voyager air conditioner condenser. Remove the air conditioning hoses from your condenser. Remove the condenser retaining bolts. Remove the condenser wiring harness. Reverse the process to install your new air conditioning condenser.
Go to Carrier documentation site: http://www.residential.carrier.com/apps/finddocs/form.jsp?b=c You will need to know the model number of your A/C unit
The air conditioner. However, the fans do nothing to affect either the temperature or the humidity,so the level of comfort is much less. We suggest sealing the room or other space as much as possible, and running the A/C at a level that is just comfortable. If the unit is exposed to the sun, providing it some shade will help a lot.
Avoid opening doors, shut down unnecessary sources of heat, and stay comfortable (and healthy).
Buy a kit at Wal-Mart or auto parts comes with instructions You shouldn't...freon in your car is under high pressure and takes special equipment to do properly. In addition, today's cars require a very specific quantity of freon to work properly. Too much will result in high internal pressures and heat, too little will prevent proper lubrication...both of these conditions will lead to an early death of the compressor and a very expensive repair. There is an organization where you can get more info, and I have help in locating good mechanics on my site. See the related links for more info. Hope this helps!
The three main functions of the evaporator are to:
a. absorb heat from the medium being cooled.
b. allow the heat to boil off the liquid refrigerant to a vapor
c. allow the heat to superheat the refrigerant vapor
