thermodynamics of air conditioning


It’s best to think of the air conditioning process as heat flowing from the indoors to the outdoors.An air conditioner works using a thermodynamic cycle called the refrigeration cycle. If the temperature outside is 120 degrees, the compressor will have to work extra hard to increase the temperature of the refrigerant to a higher temperature.After the refrigerant’s temperature is increased above that of the outdoor air’s temperature, it then flows into another set of coils, known as the condenser coils (also located outside).Since the refrigerant has been compressed (pressurized), it is now hotter than the outdoor air.

It does this by changing the pressure and state of the refrigerant to absorb or release heat.The refrigerant (aka coolant) absorbs heat from inside of your home and then pumps it outside.The air-source part refers to the place where the thermal energy is dumped, the outside air. This warmer refrigerant gas then gets transferred to the compressor (step 2 in the refrigeration cycle).Even though the refrigerant has absorbed heat from the indoor air, it is still fairly cool. THERMODYNAMICS OF AIR/WATER - CYCLE AIR CONDITIONING SYSTEMS T. C. SCOTT, SENIOR RESEARCH ENGINEER G. L. DAVIS, MANAGER ADVANCED ENGINEERING DEPARTMENT SUNDSTRAND COMPRESSORS, BRISTOL, VIRGINIA INTRODUCTION Air cycle refrigeration has been used in aircraft air conditioning systems for many years.

2, where the moisture removal ability of a LiCl solution is employed for air-conditioning. In the system, TEG solution was employed for an air dehumidification process driven by solar energy.

And vice versa, whenever you pressurize a gas, heat also increases.The way an air conditioner uses this combined law is by pressurizing and depressurizing the refrigerant to increase or decrease its temperature.If you paid attention in school, you might remember that the second law of thermodynamics states that Air conditioners transfer heat from the indoors to the outdoors.Although you may think that air conditioners create cold air, they actually extract heat from the indoor air and send it outside.When heat is removed from the indoor air, the air is cooled down. The still cool, but warmer vaporized gas enters We increase the temperature of the refrigerant because it needs to be warmer than the outdoor air.

After the air flows over the coils, it gets cold, normally dropping around 20 degrees.After the refrigerant absorbs the heat, its state changes from a liquid to a vapor.

Air Conditioner – How does it work Heat Pump, Refrigerator, Air Conditioner – basic principle of operation. this website, certain cookies have already been set, which you may delete and The refrigerant’s temperature will need to drop significantly before it can absorb more heat from the indoor air.The metering device, usually a thermostatic expansion valve, is a special device that depressurizes the refrigerant, causing a drop in temperature. Btu - British Thermal Unit - the amount of heat energy required to raise one pound of water one degree Fahrenheit.

A condenser fan blows hot outdoor air over the even hotter outdoor condenser coils.As outdoor air flows over the outdoor coils, heat is removed from the refrigerant and released into the outdoor air. If you ever need any more HVAC lessons, Why does school go so slow but summer vacation so fast?

The refrigerant’s temperature will need to drop significantly before it can absorb more heat from the indoor air.The metering device, usually a thermostatic expansion valve, is a special device that depressurizes the refrigerant, causing a drop in temperature.
There are other potential places where the heat can be transferred, such as water or ground, known as Other kinds of air conditioning systems, such as ground-source and water-source, follow the refrigeration cycle, but some of the specifics, such as location and parts may differ.When air flows over the cold coils, heat from the air gets transferred to the refrigerant inside the coils. Once the refrigerant gets cooled down, it flows back into the evaporator coils where it begins the refrigeration cycle again.Hopefully, this helps you understand the basic workings of an air conditioner.
