Eli5: What really happens when you change the temperature in an AC (Cooling) ?
In: 23
ELI5 Answer:
When you change the temperature on the thermostat, the brain of the A/C thinks “you want it colder, I am going to have to work more to cool your room down”. This causes the A/C unit to run longer to meet the temperature you set it at.
Not ELI5 answer:
Without getting into refrigeration thermodynamics, it varies significantly from system to system. In most in-home A/C systems, when the temperature is set lower, the fan will ramp up to get more air to move over the refrigerant coils thus cooling a higher volume of air per unit time. Sometimes the compressor on the refrigerant circuit has the ability to ramp up as well and will send more cold refrigerant to the coils thus allowing you to cool more air, colder.
Most units will stop or slow down when the room temperature is what you set at the thermostat.
