Turn on the air conditioner to keep warm in winter. Will the air conditioner drain water like summer?

Under normal circumstances, it is said that the air conditioning heating drain pipe does not drain, and the drain pipe comes from the machine. When heating, the evaporator of the indoor unit is hot and will not produce condensed water. When heating, the indoor unit blows hot air, so there will be no condensed water?

It is normal if there is a small amount of water droplets at the bottom of the external machine, because the external machine blows cold air when it is hot, the defrosting function of the external machine is reduced when it is old, and the radiator of the external machine will be frosted for a long time or drip when it is turned off.

Heating principle

1. 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, becomes liquid, and at the same time heats the indoor air, thus achieving the ultimate goal of increasing the indoor temperature.

2. The liquid freon enters the heat exchanger (evaporator at this time) of the outdoor unit after being decompressed by the throttling device, where it evaporates and gasifies to absorb heat and become gas, and at the same time absorbs the heat of outdoor air (outdoor air becomes cold), and the gaseous freon enters the compressor again to start the next cycle.

3. The low-pressure gas sucked by the compressor is compressed into high-temperature and high-pressure gas by the compressor, and the high-temperature gas raises the water temperature through the heat exchanger, and at the same time, the high-temperature gas will be condensed into liquid. When the liquid evaporates in the evaporator, there must be heat exchange medium at the same time. According to the different heat exchange medium, the structure of the machine is also different. Commonly used are air cooling and ground source.

4. The liquid becomes low-pressure and low-temperature gas after passing through the evaporator, and the low-temperature gas is sucked in by the compressor again for compression. In this way, the circulating water on the air conditioning side will become hot water of about 45-55 degrees. The hot water is sent to the room that needs heating through the pipeline, and the room is equipped with a fan coil unit, so that the hot water can exchange heat with the air to achieve the purpose of heating.
