The Basics Of How An Air Conditioner Keeps You Cool?
Most of the air conditioners make use of refrigeration that will chill your indoor air, by taking benefit of the physical law: Whenever any liquid gets converted to gas form (in a process known as phase conversion), this absorbs heat. And Sansone Air Conditioning exploit such feature of the phase conversion just by forcing the chemical compounds that will evaporate & condense again in the closed coils system.
Compounds involved are the refrigerants, which have several properties that allow them to change in low temperatures. The air conditioners have fans that will move the warm interior air on these cold and refrigerant-filled coils. Actually, air conditioners have a system of ducts that are made to funnel their air to & from the serpentine and air-chilling coils.
Looking at the Basic Operations
The air conditioner can cool the building as it takes away heat from indoor air as well as transfers this outdoors. The chemical refrigerant in this system absorbs unwanted heat as well as pumps this through the system of piping. This fan, found in an outside unit will blow away outside air on a hot coil, which will transfer heat from refrigerant to outdoor air.
Most AC systems have got 5 mechanical units:
- Condensor
- Compressor
- Blower
- Chemical refrigerant
- Evaporator coil
Many central AC systems function by the split system. It means, they include the ‘hot’ side, or condensing unit—which includes a condensing coil, compressor, and fan that is generally located outside the home, and the ‘cold’ side located inside the home.
How Does It Work: Central Air & Split Systems?
An air conditioner in the central heating & cooling system offers cool air through the ductwork in your home, just by offering the process, which draws out warm air within and removing the heat. In the split system, this compressor condenses & circulates the refrigerant through an outdoor unit, and changing this from gas to liquid. This liquid is forced through an indoor evaporator coil and cooling compartment.
Then indoor unit’s fan will circulate inside air that will pass over an evaporator fin. This evaporator’s fins exchange their thermal energy with air. There, the refrigerant turns out from liquid in vapor and removing heat from your surrounding air. When the heat gets removed from the air, this air gets cooled & blown back into your house.
From this point, the condenser and outdoor unit turn your refrigerant vapor back into the liquid form and removing heat. When fluid leaves an evaporator again, it’s the cool and low-pressure gas, returning to its condenser to start the trip again. The process continues until the home reaches its right cooling temperature that you want, like programmed & sensed by the thermostat setting.
How Does Cool Cycle Work?
The important thing to know about this cooling procedure is that as this refrigerant absorbs heat from the incoming warm air, this heat causes to change to the gaseous state. Definitely, if this process happened once the air conditioner will have a short lifespan, so the system has to continue cycling their refrigerant back from the gas to liquid to cool any incoming air.
Thus, when the refrigerant is changed to the gas of this process above:
- It gets moved to the other side of your air conditioner unit as well as put through its compressor that subjects gaseous refrigerant to high pressure. It creates heat energy.
- The hot and high-pressure gas passes from its compressor in its condenser coil. Thus, this condenser separates its heat energy from a refrigerant and then turns the latter back into the liquid form.
- This heat energy gets blasted outside by the external unit, whereas its newly-cooled refrigerant gets channeled in a different way; and back towards an evaporator, set to start the cooling cycle again.
This cooling fluid then reaches its compressor as the low-pressure gas. This compressor squeezes the gas or fluid, and molecules in this liquid will be packed very close together. If a compressor forces the molecules together very close, the temperature & energy rises very high. Thus, this is how an air condition unit works, when you are looking to buy a new unit for your home, make sure you check the basics before buying one.
