An air conditioning (AC) system works by removing heat from the indoor environment and transferring it to the outdoors, thereby lowering the temperature inside. The system consists of several components, including a compressor, condenser, expansion valve, and evaporator.
When you set a lower temperature on the AC thermostat, it does not directly affect the cooling rate. The AC system is designed to maintain a steady cooling output regardless of the set temperature. The cooling rate primarily depends on the capacity of the AC unit, the efficiency of the system, and the temperature difference between the desired temperature and the ambient temperature.
When you set the temperature very low, such as a temperature significantly lower than the ambient temperature, the AC system will continue to work until the desired temperature is reached. However, it does not mean the room will cool faster. The cooling rate remains relatively constant, but the AC system will need to work longer to maintain the lower temperature.
It's important to note that setting the temperature too low can lead to energy inefficiency and discomfort. The AC system will have to work harder and consume more energy to maintain the extremely low temperature, potentially resulting in higher electricity bills. Additionally, excessively low temperatures can create an uncomfortable and potentially unhealthy environment, causing issues like dry air and temperature imbalances within the room.
To achieve optimal comfort and energy efficiency, it is recommended to set the AC temperature to a moderate and comfortable level, typically around 23-26 degrees Celsius (73-78 degrees Fahrenheit) during cooling mode.
