Answer :
To understand what happens when you run an air conditioner in a room without venting it outdoors, we need to consider how an air conditioner works.
An air conditioner operates on the principle of the refrigeration cycle. It absorbs heat from the indoor air and transfers it to the outside air through a process that involves a refrigerant. There are several key components involved:
Evaporator Coil: This part is inside the room and absorbs heat from the indoor air.
Compressor: This increases the pressure and temperature of the refrigerant.
Condenser Coil: Ideally located outside, it releases the absorbed heat into the outside air.
In a typical setup, the evaporator coil cools the indoor air by absorbing heat, while the condenser coil, located outside, releases this heat outdoors. However, when the air conditioner is not vented to the outside and simply recirculates the air within the same room, both the evaporator and condenser coils are in the same space. As a result, the heat absorbed from the room is not effectively expelled:
The evaporator coil will still absorb heat and cool the air in its vicinity.
The condenser coil will release the absorbed heat back into the room.
Since both processes occur in the same room, the net effect is as follows:
- The energy required to run the air conditioner (in the form of electrical energy converted to heat) will increase the total energy in the room, ultimately resulting in a net increase in temperature.
Thus, the room will actually get warmer overall.
Therefore, based on this understanding, the correct answer is Option 1: It will heat the room.
