Where did the heat from the air conditioner go?

Air conditioning drains water from the bottom of the outdoor unit for heating, because the functions of the outdoor unit and the indoor unit are interchangeable during heating. In other words, the outdoor unit is equivalent to the indoor unit, so it will drain water from the outdoor unit when heating.

When the air conditioner is heating, the gas Freon is pressurized by the compressor to become high-temperature and high-pressure gas, which enters the heat exchanger (condenser at this time) of the indoor unit, condenses, liquefies and releases heat to become liquid, and at the same time heats the indoor air, thus achieving the purpose of increasing the indoor temperature.

The liquid freon is decompressed by the throttling device, enters the heat exchanger (evaporator at this time) of the outdoor unit, evaporates, absorbs heat by vaporization, becomes gas, and absorbs the heat of outdoor air (outdoor air becomes cold). Freon, which turns into gas, enters the compressor again and starts the next cycle.

Precautions for air conditioning use:

1, set the temperature not too high.

When the air conditioner is turned on, it can be set to a slightly higher temperature than expected (for example, 28℃), so that the indoor temperature can quickly reach the expected temperature. After running for about 15 minutes, the temperature can be reduced (24℃ or below), and it can be changed to low air volume or energy-saving mode, which can greatly reduce the power consumption of air conditioning.

2. Warm wind blows down the room, which makes the room warm up faster.

Cold air is heavier than hot air. Therefore, air conditioning heating makes the air outlet downward, that is, hot air blows downward. Doing so will naturally raise the blowing hot air, thus increasing the overall temperature of the room, greatly improving thermal efficiency and comfort, and reducing power consumption.
