Cold Fridge, Warm Freezer

I had pretty much the same problem with an old (I think) Frigidaire. It had the compressor & evaporator in the bottom of the fridge and used a rectangular air duct to get cold air up to the freezer. After a series of very humid days and lots of ice use (opening and closing the freezer door repeatedly) the air duct iced up. I had to use a hair dryer to blow hot air down the duct to defrost it, emptying the drip pan under the fridge each time it filled up

1. is an evaporator coil and heat exchanger the same thing?

In my opinion it is the same thing. A heat exchanger is a device built for efficient heat transfer from one medium to another. They are widely used in space heating, refrigeration, air conditioning, power plants, chemical plants, petrochemical plants, petroleum refineries, and natural gas processing. One common example of a heat exchanger is the radiator in a car, in which the heat source, being a hot engine-cooling fluid, water, transfers heat to air flowing through the radiator (i.e. the heat transfer medium).

2. where r the evaporator,drain pan and drain located at?

It depends on the type of car you have. The evaporator is normally under the right side of your dashboard. The drain is usually on the outside of the firewall or underneath the car in that area

3. What causes condensation on the outside of the AC PVC pipe and evaporator coil housing?

How long have you lived in the house? Have you gone through all the seasons yet. Condesation is normal, especially in the summertime when the air is very humid. If I understand correctly, your unit is in a AC water pan. That is one of the reasons they use these pans, to catch the condensation and direct it to the outside

4. finding my evaporator core on 2001 aztek?

Taking out the glove box is one of many steps involving most of the dash being removed. Pay to have this repair performed by a qualified shop

5. See if you know, experts! why is my evaporator coil icing up?

On an AC unit? Not enough air flow for the delta T presented. Check for: system balance, clogged filter, fan speed/functionality.

6. what exactly does an evaporator coil do in a freezer or cooler?

When liquids change state to gases, they absorb heat. When gases change state to liquids, they lose heat. By changing the pressure of a gas, you can change the temperature or state (the basic equation for this is the "Ideal Gas Law": PV=nRT). So, when a compressor pushes the refrigerant gas into the high-pressure side of the system, the gas liquifies ans increases in temperature. This is usually done on the outside (back) of a refrigerator where the higher temperature enhances heat exchange with the room (i.e. heat is lost to the room). A nozzle separates the high pressure from the low pressure side of the system, and when the liquid passes through that nozzle, it becomes a gas and drops in temperature. This enhances heat exchange from the inside of the refrigerator to the coils. Hope that helps.

7. Where does Evaporator Coil go on the Hz forced air furnace?

front of the air handler drain pan down then mount duct work to coil run your linesets and 2 wire to the condensor then run your power from the breaker to the condensor mount drain from unit to outside and drainpan under unit to outside all done

8. How hot does the HVAC "evaporator coil" get when heating the house?

In Air conditioners having heating and cooling options, when you Select heat mode there is a four way valve which will change the flow of refrigerant from the compressor to interior side (evaporator coil). Then the out side coil will work as evaporator and inner side will work as condenser

9. Do you need to remove the evaporator in order to change the expansion valve on 2002 CRV?

The expansion value is in the box with the evaporator you would need to pull it out .You might be able to take the black box apart without pulling it all the way out .( MAYBE )

10. what can an evaporator leak do to my car I have a 2000 mitsubishi eclipse?

The evaporator changes high pressure refrigerant into low pressure vapor. If you have a leak it will quite obviously get out and youll need to fill it more often than washer fluid

What Is the Proper Way to Clean a Evaporator Coil?
If you are cleaning the outside of the coil, the condensate pan, etc., I would use degreaser and water. Cleaning the inside of the coil should be left to a pro.1. 98 Buick Lesabre evaporator coil?Unless you are taking it out and replacing it, there is no reason to access it. There is nothing serviceable. But anyways, it under your dashboard, in the same ductwork as your heater core. Get to it through the glove box, or underneath, taking off the lower ductwork.2. Help with central AC and copper tubing from evaporator coils?Regarding your condensate drain tube - is your home on a slab or pier and beam ? If you are on a slab you should be able to walk around and look until you see a stream of water exiting the house. If you are on pier and beam you would have water pooling under the house, and that might be a very bad thing, so you want to get under the house and look for the tube. Some people have the water drain into their sewer system, which can be done with a floor drain or into the water drain pipe for the washing machine. As for the people who service the AC unit, I suggest you take several photographs of your problems and then personally visit a business that services AC units and discuss with a manager your frequent problems, then visit another service business with that information and see what they tell you. Once you decide on a service company it helps them to have everything known, on a checklist, before the service tech arrives on the premises; the checklist is to ensure all of your questions are answered.3. What's the Difference Between the Condenser and Evaporator Coils?The evaporator and condenser coils in an air conditioner are heat movers. One extracts heat from inside your house and the other dumps that heat outdoors. The end result of this process is a cooler, more comfortable indoor environment. In addition to getting the heat out of the house, the evaporator coil performs the function of reducing humidity. Because moist air holds heat energy, lowering the humidity promotes more effective cooling. Central air conditioning is a closed-loop system. What flows through that loop is refrigerant - a substance that readily absorbs heat energy, shifting from a vapor to liquid state and back again. Through an insulated conduit connecting the coils, refrigerant flows from the indoor evaporator coil through the system compressor to the outdoor condenser coil, then loops back to the evaporator. Here's how the evaporator and condenser coils perform the heavy lifting of keeping your house comfortable: Cold refrigerant vapor passes through the evaporator coil tubing as warm indoor air is drawn through coil air passages by the air handler blower. Heat energy in the air conducts through the copper surfaces of the coil and is absorbed by the frigid refrigerant. The refrigerant flows through the conduit to the A/C outdoor component. A compressor pressurizes the refrigerant, concentrating heat energy and converting it to a hot liquid as it enters the condenser coil. Rapid condensation inside the condenser coil tubing causes the hot refrigerant to convert to a liquid state and rapidly release the stored heat energy. As the condenser fan pulls air through the coil passageways, this heat is dispersed by aluminum coil fins into outside air. Liquid refrigerant now completes the return trip to the evaporator and the process repeats. We are your source for residential and commercial services in the Norfolk County area.4. why does an ac unit being low on refrigerant cause the evaporator to freeze up?The freon enters the evaporator through a thermal control valve. The pressure drop causes the freon to change from a liquid to a gas and in doing so cools the evaporator. If the freon is low the pressure at the output of the evaporator falls below its normal level and with freon, pressure is equivalent to its temperature. Normal output pressure for R-134a should be above 30 psig ( 34.5 degrees F), if it drops below 28 psig (32.2 degree F) there is a chance the evaporator can freeze.5. What kind/size of Evaporator Coil do I need for a 2.5 Ton Trane A/C Condensor (XB12)?You sure thats not a HEAT PUMP? XB12's were heat pumps. If memory serves me that was on a 12 seer rated. So in this case you going to want to get a R410A 13 Seer 2.5 Ton cased coil. It will match the system as closely as it was originally designed. The system is R22. You will not find the proper matched "12 seer coil" A R410A Evaporator Cased coil will work fine. Which will be rated for R410A / R22. You also going to need a Bi-flow liquid line drier. You going to need to consult with an HVAC company to complete this installation as this will be WAY over your head. And if Im correct if this is a heat pump, your going to have to change out the thermostat or you can just wire it up for cooling only if you have a gas furnace.
