What is the status of aluminum coils in an air conditioner when they accept heat from inside the house?

When aluminum coils in an air conditioner accept heat from inside the house, they must be cooler than the air inside the house. This temperature difference is essential for the process of heat transfer to occur. In order for heat to flow from a warmer area to a cooler one, the air inside the house must be at a higher temperature than the coils.

The aluminum coils facilitate the absorption of heat from the indoor air, which effectively cools the air and lowers the temperature within the space. The efficient transfer of heat from the warmer indoor air to the cooler coils is a fundamental principle of thermodynamics. It allows the refrigerant within the coils to absorb this heat, causing it to evaporate and carry the heat away from the interior space, ultimately allowing the air conditioning system to function effectively.
