Is it better to blow hot or cool air from the outdoor unit of the air conditioner?

In summer, hot air must be blowing, and the hot air represents the normal operation of the compressor, which takes away the heat of the high-temperature and high-pressure refrigerant (commonly known as freon) and converts it into the indoor refrigeration effect better. If you have a cold air in your home, first determine whether the operation mode is turned on or not. Another reason is that the compressor does not start; When the indoor temperature arrives, the compressor stops working, or the compressor fails and shuts down, but the fan is spinning, blowing natural wind.

Another reason is that there is too much refrigerant to provide refrigeration conditions.

If the outside unit of the air conditioner is cooling, it must blow hot air, and if it is heating, it blows cold air, because its working principle is to bring indoor air to the outside.

The hot air or cool breeze from the outdoor unit of the air conditioner is determined according to the weather, it is better to blow hot air in summer, and it is better to have a cool breeze in early spring in winter.

Of course, the hot air is good, and the air conditioner blows out of the hot air, which means that the refrigeration effect of the air conditioner is better.

The air conditioner plug-in should blow hot air in summer and cool air in winter, otherwise it means that there is a problem with the air conditioner and it is time to repair.

In summer, the air conditioner needs to blow a cool breeze, so it is better for the outdoor unit to blow hot air, so that the indoor temperature will drop.

The outdoor unit of the air conditioner must be blowing hot air, and it will definitely not be cold air!

The outdoor unit of the air conditioner must blow hot air to suck out the indoor heat and release the cold air.

The external machine, hot air or cold wind, is based on the weather, the outdoor machine must be hot in summer, and cold in winter

In the summer, of course, it is to blow hot air to bring the heat out of the house.

The air conditioner will definitely produce hot air in summer and cold air in winter!

AbstractThe heat sink of the outdoor unit of the air conditioner is the condenser, and the high-pressure and high-temperature refrigeration gas in the tube becomes a liquid refrigerant through heat dissipation. Therefore, when refrigerating, the condenser of the outdoor unit should blow hot air.

The outdoor unit condenser blows out the compression heat of the refrigerant, and if the air blows out is not hot, there are two reasons:

1. The compressor is not working;

Refrigerant leakage and serious insufficiency.

refrigeration principle; After the air conditioner is energized, the low-pressure steam of the refrigerant in the refrigeration system is sucked in by the compressor and compressed into high-pressure steam and discharged to the condenser. At the same time, the outdoor air drawn in by the axial fan flows through the condenser, taking away the heat released by the refrigerant, causing the high-pressure refrigerant vapor to condense into a high-pressure liquid. The high-pressure liquid is sprayed into the evaporator after passing through the filter and throttling mechanism, and evaporates at the corresponding low pressure to absorb the surrounding heat.

At the same time, the cross-flow fan continuously enters the ribs of the evaporator for heat exchange, and sends the cooled air to the room after heat release. In this way, the indoor air is constantly circulating and flowing to achieve the purpose of reducing the temperature.

In winter, the wind blowing outside the air conditioner is cold or hot.

Take a look. Hot air should be blown.

Summary. The principle of air conditioning heating: when the air conditioner is heating, the gas freon is pressurized by the compressor to become a high-temperature and high-pressure gas, which enters the heat exchanger of the indoor unit (at this time, the condenser), condenses and liquefies heat to become a liquid, and at the same time heats the indoor air, so as to achieve the purpose of increasing the indoor temperature.

Hello, dear. I have seen your question, I am now guessing the answer to the information, please wait for me for five minutes, I will provide you with the information you need as soon as possible. Sedan type.

Hello, dear. According to the query of relevant information about the working principle of the air conditioner, the external unit of the air conditioner produces cold air when it is heating in winter.

The principle of air conditioning heating: when the air conditioner heats Qi Yan, the gas freon is pressurized by the compressor to become a high-temperature and high-pressure gas, which enters the heat exchanger of the indoor unit (at this time, the condenser), and the condensation liquefies and releases heat to become a liquid, and at the same time heats the indoor air, so as to achieve the purpose of increasing the indoor high jujube temperature.

Is there anything else you'd like to know? If there is a kemato, I will continue to serve you. If not, please kiss me a thumbs up, it's an honor to serve you in the absence of inspection, and thank you again for your kiss.

Inhale air. The compressor sucks in low-pressure gas and compresses it into high-temperature and high-pressure gas through the compressor, and the high-temperature gas increases the water temperature through the heat exchanger, and the high-temperature gas will condense into liquid at the same time. The liquid enters the evaporator for evaporation, and the liquid becomes a low-pressure cryogenic gas after passing through the evaporator, and the cryogenic gas is sucked in by the compressor again for compression.

There is a component called the four-way valve during heating, so that the flow direction of the refrigerant in the condenser and evaporator is opposite to that of refrigeration, so when heating, the outdoor air blows cold, and the indoor unit blows hot air.

In fact, it is the principle of expelling heat during liquefaction (changing from a gas to a liquid state) and absorbing heat during vaporization (from a liquid to a gas) that I learned in junior high school physics.

When the air conditioner is heating, the internal unit blows warm air, but why does the outdoor unit blow cold air?

1.When the air conditioner is cooling, the indoor unit emits hot air and the outdoor unit produces cold air, which is because the cold and warm four-way steering solenoid valve in the outdoor unit of the air conditioner is out of control. When the air-excited Kaisan is refrigerated, the four-way steering solenoid valve is not active, and maintains a positive direction.

2.When heating, the four-way steering solenoid valve will change the steering and change the flow direction of the refrigerant, so that the original refrigeration indoor unit becomes Ming's heating, and the heating outdoor unit becomes refrigeration.

Summary. In the refrigeration season, the air conditioner blows cold air outside, first check whether the compressor is started, after starting, listen to the compressor buzzing and stop, only the fan turns, indicating that the starting capacitor of the compressor is broken, and it is replaced. If the external unit is normal, observe the (thin tube) of the external unit, if there is frost, it is a lack of refrigerant.

Under normal circumstances, there is wet condensate on the surface of the copper valve of both the thick pipe and the thin pipe, and if it is dry, the compressor is not working.

In the refrigeration season, the air conditioner blows cold air outside, and the code lets the compressor first check whether the compressor is started, and after starting, listen to the buzz of the compression bridge mold next to the machine and stop, only the fan turns, indicating that the starting capacitor of the compressor is broken, and it is replaced. If the external unit is normal, observe the (thin tube) of the external unit, if there is frost, it is a lack of refrigerant. Under normal circumstances, there is wet condensate attached to the surface of the copper valve of the thick pipe and thin pipe, if it is dry, the compressor is not working.

Can you add, I don't quite understand it.

The main reason for the air conditioner is that the loose cover in the whole system is missing freon, leak detection and fluoride. In the case of a small service life of the air conditioner, the probability of failure of the compressor starting capacitor is not large.

What happens when the air conditioner blows cold wind in summer, hello! In summer, the air conditioner outside the fan blows cold air for possible reasons, and the air conditioner failure (for example, lack of refrigerant) does not refrigerate the wind that comes out of the air is natural wind and becomes an electric fan, so it feels like cold air blowing. The air conditioner is running in a heating state:

If the four-way valve fails to return, or is powered on, you can check the voltage at the input end of the four-way valve, the room temperature sensor, and the main board of the indoor unit. If there is cold air coming out of the external unit, the compressor should stop working in 3-5 minutes. Specific problems can not be diagnosed in one sentence, which is relatively rare.

If you can't solve it, please ask a professional to repair it. Hope it helps!
