Written In many ways air conditioning and refrigeration systems are very similar. Both use specially designed chemicals, the physical effects of the compression and expansion of gases, and the conversion of gas to liquid to reduce the temperature of air. The varying uses of these systems, however, mean refrigeration and air conditioning systems have a handful of key differences in the design and operation.SupplyA major difference between refrigeration and air conditioning is the point of supply for the gases. Refrigeration systems have gas installed in a series of tubes. In old refrigerators, this gas was chloro-flouro-carbon, or CFC, but this has harmful effects on people, so refrigerators not contain HFC-134a. HFC-134a is the sole gas used as a coolant in refrigeration systems. Air conditioning systems use built-in chemicals, but also air from the room or rooms being heated. Gases built into air conditioning units cool air that circulates through the unit; the unit then redistributes the cooled air through the room.

CirculationAir conditioners have circulation systems designed to project cool air away from the units while refrigeration units have circulation systems designed to retain coolant in a confined space. Refrigeration systems circulate cool liquids and gases through a series of tubes and vents. Cool air from within a refrigerator is sucked into a compressor that recycles the gas through the tubes. wall mounted air conditioner heater unitsAir conditioners, while also employing tubes in the coolant system, have fans for the dispersal of air. affordable air conditioner unitsUnlike refrigeration systems, which keep gases contained to a pre-determined space, air conditioning systems disperse cool air throughout areas of unknown volume.how ac split unit works

VaporizationBoth air conditioning and refrigeration units depend on converting liquid to gas in the cooling process, but the manner in which they achieve this is different for each system. Air conditioners use something called an evaporator to convert a liquid to a gas. An evaporator is a small, narrow hole designed to change the pressure of a liquid so that it evaporates. Refrigeration units, on the other hand, cycle HFC into a low-pressure chamber designed to boil the gas. This boiling causes HFC to vaporize. Vaporization is the process of converting a liquid to a gas and can be accomplished one of two ways: boiling or evaporation. Thus air conditioning units vaporize liquid through evaporation while refrigeration systems do so through boiling.Written Refrigeration refers to processes that take thermal energy away from a place and gives off that energy to a place with a higher temperature. Naturally, thermal energy flows from a place with a higher temperature to a place with a lower temperature.

Therefore, refrigeration runs against the natural heat flow and so it requires work to be done. Refrigerator is a name that we use for devices that are used to keep food at low temperatures. A refrigerator consists of a fluid called refrigerantwhich gets expanded and compressed in a cycle:When refrigerant enters the compressor, the refrigerant is compressed adiabatically. This raises the temperature of the refrigerant.Then, the hot refrigerant is sent into the condenser under high pressure, which is typically a tube outside the refrigerator. Here, the temperature of the refrigerant is higher than the temperature of the surroundings. So, the refrigerant gives off heat to the surroundings and gets condensed into a liquid. If you touch the tubes at the back of a refrigerator, it feels hot because you are feeling the heat given out by the condenser.Next, the refrigerant goes through an expansion valve, where the pressure of the refrigerant is lowered. The refrigerant expands here, evaporating and cooling down.

The refrigerant now enters the evaporator, which is a set of tubes inside the refrigerator. At this stage, the refrigerant is at a temperature lower than the temperature of the air inside the refrigerator. Now, the refrigerant draws in heat from inside the refrigerator. This is how heat is removed from inside a refrigerator.Once the refrigerant goes through the evaporator, it is sent again into the compressor… and the cycle continues repeatedly.Air conditioning is a type of refrigeration where thermal energy is taken away from the air in a large space such as a room or a vehicle. Air conditioners are fitted into rooms so that they cool the air inside them. Air conditioners also reduce humidity in rooms, because the water vapour in the room can condense around the colder parts of the air conditioner. The condensed water can be then drained off.Air conditioners work in the same way as refrigerators. The primary difference between an air conditioner and a refrigerator is that air conditioners are not only concerned with maintaining the temperature of the air;

they also help to regulate humidity and filte the air. Air conditioners also consist of fans in order to circulate air, so that the hot air comes into contact with the evaporator at a faster rate.Written Almost the same... conducting away the heat off from one place to another. Air conditioners take higher load than refrigerators. Air conditioners expel the heat out of the room, refrigerators only out of the refrigerator. Air conditioners also filter the air. Air conditioners finally cool the room, refrigerators cool the inside. Better loss prevention in refrigerators. Air conditioners losses are comparatively high. Air conditioners consume more power.Source: 3. What is the difference between a refrigerator and an air conditioner? I'm converting my two car garage into a home theater and was seeking some advice on the cheapest way to heat, cool, and dehumidify the room. Here are some details: Garage was once a model home office so the walls, ceiling, and garage door are insulated.

Dimensions are about 20' x 20' x 10'. The garage has no windows. The garage has attic access. I live in Austin, Texas. Temperatures range from triple digits down to occasional freezing. I'm am most concerned about the cooling and dehumidification. I can use an electric heater if need be to warm the garage during the winter. Since I will have sensitive home theater equipment in the garage, it will be important that the garage remain within a normal room temperature and humidity level. I'm trying to keep the project within $1500 but I'm afraid that may be out of reach... I have central air and heating in a small 2200 sqft home. heating garage home-theater cooling If your current AC is not adequate to extend to the garage area, then a ductless mini-split wall mounted AC unit is probably ideal for your situation. Once installed, you'll likely exceed the $1500 budget, but I think it's the best of the options. You wall mount half of the unit inside the home and run the cooling lines through the wall and out to an exterior coil.

They also have a condensation drain line that you run outside to help with the humidity. You can always go with a window AC / Heater or something like this; If you go this way make sure you size it out to match the room. This one shows that it has a dehumidifier also. I think you are right about your unit not being able to handle your garage also. They are usually sized for the house. Too large a unit is just as bad as too small a unit. Then you will also need a return air duct. While ease of use and having everything you need in one unit might be a plus, the cons are going to be the noise when on and the possibility of having to have an extra electrical circuit put in. If your panel is in or outside the garage that will make it a lot easier, the other side of the house will be a chore. There are lost of style to choose from so choice won't be a problem. When converting my garage to home theater I purchased one of those portable ac units cut about a 5" x 5" square hole installed dryer flap so it closes when ac not on.
