Does this unit have the heating element in it as mine just blows cold.


THERE is heat dissipation on the backside or the refridgerator sometimes by a vin or just simply heat up , but no heating

heat is removed from products which are placed in the refrigerator

A compressor with (r22) or 407(a/ c ) or whatever in a circuit that becomes cold as soon as the compressor worked it must be working freezing if not or only a part is freezing it can be a solenoid valve. or a start relais on the compressor thats not in function.

Refrigerator Trouble The Outside of Refrigerator Hot


<p>There are many reasons why the <b>outside of a refrigerator can be hot</b>. Some of these are for good reasons and some of these can be cause for concern because they are <b>signals of trouble</b> or impending trouble.<br /> <p><br /> <br /> <p>First let's look at the good reasons for why the <b>refrigerator outside cabinet</b> could be hot.<br /> <p><br /> <br /> <p>Because of the cold inside of the <b>refrigerator</b> the out side of the <b>refrigerator will sweat</b> or even get frosted if the metal surface is not heated. To keep the sides heated there are either parts of the <b>condenser coil</b> or <b>electric heating elements</b> in the sides of the unit. The center post of <b>side by side refrigerators</b> is heated by <b>electric heating coils</b>. These feature keep <b>refrigeration units</b> dry, especially in <b>warm humid climates.</b> Most of these features can be turned of and on by using the <b>energy saver switch </b>or the<b> condensation switch</b>, whatever the unit maker has chosen to call it.<br /> <p><br /> <br /> <p>Now, if your <b>refrigerator is hotter then normal</b> on the outside, it can be an indication that your are either having problems or about to have problems. These problems can be simple or they can be serious.<br /> <p><br /> <br /> <p>If you have <b>left the door open</b> and the refrigerator has had to run for a long time then the sides could get hotter then normal. <br /> <p>If you have just placed a <b>large amount of hot food</b> in the refrigerator then the extra run time to cool the food can cause it to heat up.<br /> <p>If the <b>door seals are bad</b> then the <b>refrigerator will run mor</b>e and cause <b>excess heat.</b><br /> <p><span>If your</span><b> condenser coils are plugged with dust </b><span>bunnies so big you can name them,</span><b> </b><span>the heat is not being removed by the </span><b>condenser coil</b><span> and so the sides are getting too much heat and the </span><b>refrigerator is running too long</b><span>, causing a compounding of your problems.</span><br /> <p><br /> <br /> <p><span><span>Refrigerator </span></span><u><a href="/../support/r4024657-refrigerator_condenser_coil_cleaning"><span><span>Condenser Coil Cleaning</span></span></a></u><span><span> Refrigerator Repair</span></span><br /> <p><br /> <br /> <p>These are the simple things... the effects are either temporary or can be fixed easily.<br /> <p><br /> <br /> <p>Now for the problems that can cause too much heat but are much more difficult to fix.<br /> <p><br /> <br /> <p>The <b>condenser fan has gone bad </b>and stopped causing the condenser coils not to do their job and the excess heat to be transferred to the sides of the refrigerator. If the <b>condenser fan is not running</b> but the <b>refrigerator compressor</b> is, then the fan motor will need to be replaced. This is not a real hard job, but it is tight quarters in there and it will take some time and a lot of patience for most <b>refrigeration units</b>.<br /> <p><br /> <br /> <p>The worst case is if the<b> refrigeration system</b> of your <b>refrigerator has developed a leak</b> and because of this the <b>compressor is running longer then normal</b> and also is not cooling the unit properly. Because of the higher temperatures inside the refrigerator and the continued heat from it cooling a little bit the sides or especially the<b> electrically heated parts, </b>like the center post<b>,</b> will heat up rapidly and get much hotter then normal. To fix this problem will require a licensed tech. Who can identify the leak and repair it. Then <b>vacuum the refrigeration system</b> and recharge it again.<br /> <p><br /> <br /> <p><a href="/../support/r4588788-refrigerator_or_freezer_not_cooling_or">http://www.fixya.com/support/r4588788-refrigerator_or_freezer_not_cooling_or</a><br /> <p><br /> <br /> <p><br /> <br />

How to troubleshoot and, repair your RV refrigerator


if this is a gas absorption refrigerator make sure it's level while operating.
check for heat at the roof vent if no heat check heating element or, gas burner behind the refrigerator accessible through the refrigerator outside hatch; next: check the relay and, inverter it is located under the refrigerator front if all these things check ok and, especially if you find a yellow power on the gas refrigeration unit the tanks behind the refrigerator box; you must replace the gas refrigeration unit by: removing the refrigerator from the cabinet from the front then lay it down and remove the gas refrigeration unit replace it with a new one but, don't forget to remove the 3' long spiral metal strip from the old gas refrigeration unit exhaust vent and, reinstall it in the new gas refrigeration unit the gas refrigeration units can be purchased online.

Why do I have a low refrigerant warning on my Jandy ee-ti Heat pump heater


Heat pumps work the same way as a refrigerator, just in reverse.

Because they do, they are dependent upon refrigerant. If the refrigerant is low this could be the cause of the unit not functioning.

Refrigeration is actually a fairly straight forward easy to understand process....


Refrigeration is actually a fairly straight forward easy to understand process. Although there are several ways that refrigeration can be achieved in a system, the most common is vapor compression, in which the compressor is the heart of the system. The temperature of the refrigerant is related to its pressure. For example R134 is roughly -15 degrees Fahrenheit at no pressure. (Thats gauge pressure and not absolute). When compressed to 250 psi R134 is about 148 degrees. 
 Starting from the compressor, the refrigerant vapor is compressed. In the process it will heat up hotter than the surrounding air. As the refrigerant passes through the condenser, heat is given off since it is hotter than the surrounding air and as a result it condense and turns liquid.(thats why it is called a condenser). The liquid refrigerant then passes through an expansion valve or a capillary tube where it turns into low pressure liquid and as it passes through the evaporator  absorbs heat from its surrounding since it is much colder. This makes the refrigerant turn into gas and evaporates (again it is why it is called the evaporator) absorbing tremendous amount of heat. Then refrigerant vapor  passes through the accumulator in which  moisture accumulates ( why it is called the accumulator) before it is sucked into the compressor to be compressed again. (Why do you think the compressor is called compressor? you know the answer by now) 
 The whole system is really a means for heat transfer for removing heat from one place and expelling it outside  in which the refrigerant is the vehicle.  Heat always travel from hot to cold. If something is hotter than the surrounding, it gives off heat and if it is colder, it absorbs heat. Simple as that. There is a thing called latent heat of vaporization or in thermodynamic term it is called enthalpy of vaporization. This simply means when liquid reach its boiling temperature at a constant pressure it will no longer get any hotter. . For example when you boil water at sea level it stay 212 degrees no matter how much heat you put under the pot. You can also think of it as putting heat into it but it is not doing anymore work. since the water is not getting any hotter. If there was meat in there it would not get soft any faster by adding more heat. The water will just absorb all that heat without getting any hotter. That is just one of those wierd law in physics and it is the underlying principle in theory of refrigeration. It is the fact that when liquid evaporates, it absorbs tremendous amount of heat and carries it away. Rub alcohol on your skin and the skin feels cold as the alcohol  evaporates. Thats a simple form of refrigeration at its very basic. 
 There are other types of refrigeration for example another one is called "absorption system". This kind uses heat to vaporize liquid (usually ammonia and water solution) mixed in an absorbing material. as the substance evaporates it accumulates on the other end as liquid. When heat is taken away, the whole thing cools down and the pressure drops to a point so that the liquid that has accumulated will evaporate and be collected back on the absorbing material. This produce refrigeration. It has no moving parts no compressor and just uses heat. An example of this is the propane refrigerators. . The last one would be thermoelectric. If current is passed through two dissimilar metals one of the metal will get cold at the junction, and it is called the peltier effect. Coolers that plugs into cigarrete lighter are example of these type of device. They are not really very efficient but have some advantages such as it can be used as food warmer when the current is reversed, and they are lightweight and portable.

Before I start up my topic I will like to explain what the word refrigerant means and other things that I fill you have to know more on the subject matter.
What are refrigerants? Refrigerants are fluids that absorb heat at low temperatures and rejects heat at higher temperatures. The principles of refrigerant allow for heat pumps and straight air conditioners to function properly; because of their pressure temperature relationship. This relationship allows for heat transfer.
In the HVAC industry refrigerants are given a trade name known as "R" names. Examples of these names are R22, R134a, and R502. These names help to describe the different types of refrigerants. Refrigerants have various chemical make ups, along with different properties. Some refrigerants are only able to work in high pressures while others use low pressures to function properly.
There are three main make ups of refrigerants that are currently used. Hydrogenated Fluorocarbon Refrigerants (HFCs), which is made up of hydrogen, fluorine, and carbon. Because they do not use a chlorine atom (which is used in most refrigerants) they are known to be one of the least damaging to our ozone. Hydrogenated Chlorofluorocarbon Refrigerants (HCFCs), which are made up of hydrogen, chlorine, fluorine, and carbon. These refrigerants contain minimal amounts of chlorine; they are not as detrimental to the environment as some other refrigerants. Chlorofluorocarbon Refrigerants (CFCs), which contain chlorine, fluorine and carbon. These refrigerants carry high amounts of chlorine so they are known for being the most hazardous to the ozone layer.
Sometimes refrigerants consist of a two or more chemical compounds. These blends break down into two types: Zoetrope’s and Azeotropes. Zeotrope A zeotrope is a liquid mixture that obeys Raoult's law. It shows no maximum or minimum when vapour pressure is plotted against the composition at a constant temperature.Zeotrope refrigerant mixes are mainly made of three different types of refrigerants. The characteristic that describes this type of refrigerant is that all three refrigerants keep their own properties; they act as 3 individual refrigerants. Azeotropes are mainly a blend of two refrigerants. The property that defines this type of refrigerant is it acts as a single refrigerant. This effect the boiling points of both types of refrigerants.
The most important fundamentals of refrigerants before expanding into how they work. This key principle is that refrigerants do not make things 'cold' they remove heat. This principle is preached in the HVAC industry. It is a common misunderstanding of homeowners and technicians.
A pressure temperature relationship is a way of describing the specific temperature that relates directly with the pressure of a substance. This allows control of refrigerants boiling temperatures. Controlling a refrigerants boiling temperature allows for proper heat transfer.
Heat transfer is when heat from one place is transferred to another place, this is also referred to as a refrigerant cycle. Generally we control heat transfer through air, water and refrigerants.
This type of heat transfer happens through conduction. Conduction is when heated molecules, with lots of movement, collide with slow moving molecules. The warmer molecules, fast moving, always move towards the cooler ones, or the slow moving molecules.
Refrigerants are sold in disposable container that includes a check valve. This limits the reuse of old refrigerants and prevents mixing refrigerants. Refrigerants are identified by a standard color code. The labels also contain information on which type of refrigerant is in the container along with any safety hazards there are.
There are several safety hazards when handling refrigerants. In order to help prevent damage to the ozone, technicians are required by law to become EPA certified. There are four (4) main types of certification; Type I, Type II, Type III, and UNIVERSAL. Type I includes small appliances such as refrigerators. Type II includes high pressure appliance with the exclusion of small appliances such as split-systems. Type III includes low pressure systems such as chillers. A Universal certification includes all three types of certifications. For more information on refrigerants, their properties, how they effect the environment, and becoming certified.

I want to know about refrigerater but without compressor ,How it run ,Which technology use it


A refrig doesn't cool . It removes heat which is why the coils get hot . With the condensor mounted on the back of the fridge , air curculation dissipates the heat from the coils . Remember , this heat , is the heat being removed from the inside , by the refrigerant being pumped by the compressor . Some fridges , have a condensor fan to remove the heat from the bottom coils , and to keep the compressor cool . The thermostat , tells the compressor to cut off , when so much heat is removed from inside the ref . The property of refrigerants , is to attract heat , and since aluminum is a good conductor , the evaporator coils inside the freezer are made of aluminum . As the coils get colder , the fan inside the freezer , blows into the refrigerator , and returns to the freezer in a circular motion , thereby cooling the refrigerator . During defrost , wheather it be adaptive or mechanical , is to melt the frost accumulated on the aluminum freezer coils . If too much frost accumulation , the frost will act as an insulation , like the insulation on wire , then the ref. will not get cold .

Heat along inside of doors


The heat is to prevent condensation from building on the outside of the cabinet. It is sometimes done by a heating element which can be turned off (Energy Saver mode On), or by the way the refrigeration is piped (and ther eis nothing that can be done about it.).
