Is the air conditioner turned up or down?

Air conditioning can definitely adjust our indoor temperature under normal use. Generally speaking, refrigeration is a function that we use most, which has brought us great help. But when cooling, does the air conditioner blow up or down? Generally speaking, it is better to blow upward, because the air conditioner is downward, which can have better refrigeration effect.

In the process of air conditioning wind direction adjustment, you can use up-and-down scanning and left-and-right scanning to adjust the wind direction of air conditioning. This can well control the blowing direction of the cold air of the air conditioner. If the bedroom is air-conditioned, you can turn up the wind direction of the fan and don't blow it directly at people. If it is in a relatively large place such as a bedroom, the air conditioner can automatically adjust the direction, which can play a good role in cooling or heating the bedroom.

We must adjust the wind speed and direction when the air conditioner cools. In fact, everyone should pay attention to the direction when adjusting the air cooler. Does the air conditioner blow air up or down? In fact, we usually blow up the air conditioner, which is better, because if the cold air is blown up, the refrigeration can be more uniform. In fact, besides the wind direction, we should also pay attention to the temperature of cold air. Generally, it is more appropriate to keep the air conditioning temperature around 26 to 28 degrees Celsius.

The wind is blowing, and it's getting colder. Turn on the air conditioner for refrigeration, it is best to turn the air conditioner with the wind direction upward, because the proportion of cold air is larger than that of hot air, so that the cold air can be circulated for hundreds to hundreds, and at the same time, the cold air can be prevented from blowing directly on the body. Turn down the air conditioner when heating. The temperature difference between indoor and outdoor is about 6 or 7℃. If the temperature difference between indoor and outdoor is too large, it is easy to make people's resistance drop between sudden cooling and sudden heating, causing air-conditioning diseases similar to cold symptoms. scientific research

Is the cold air sinking or rising?

The cold air drops.

The density of cold air is high, the temperature is low, the Brownian motion between molecules is small, and the space required by each molecule is small, so there are many molecules in the same space, so the density is high. Cold air is the air in the low temperature zone. Cold air and warm air are defined by the horizontal difference of temperature. The distant Arctic Ocean and cold Siberia are the cradles of cold air.

Most cold air masses are formed in the polar regions and Siberia, with a range of thousands of kilometers and a thickness of several kilometers to dozens of kilometers. Cold air crossing the border will bring rain and snow. , will make the temperature plummet. The intensity of each cold air intrusion is different, strong or weak, and the cooling rate is also more or less.

Impact:

The main influence of cold air intrusion is to bring cooling and strong winds, and sometimes there will be a wide range of rain and snow weather, which is the result of the intersection of cold and warm air. When the warm and humid air conditions are not good and the circulation conditions are unfavorable, the invasion of cold air does not necessarily bring precipitation weather. Therefore, it is not that the stronger the cold air, the stronger the rain and snow weather.

Human body: First of all, strong cold air can obviously reduce the humidity in the air, make the nasopharyngeal mucosa dry and produce tiny wrinkles, and cold viruses can take advantage of it.

At the same time, due to the decrease of temperature, the local temperature of nasopharynx can be reduced to about 32℃, which is just suitable for the virus to grow and reproduce in the mucosal gap. In addition, the stimulation of the respiratory tract by strong cold air can cause local vasoconstriction and decrease the immunoglobulin secreted by the mucosa, which provides more favorable conditions for the invasion and reproduction of cold virus.

Within 2-3 days before and after the attack of strong cold air, the average temperature and minimum temperature suddenly dropped, and the temperature regulation function of human body was difficult to adapt to this sudden cold stimulus. If you don't add clothes to keep warm in time, you will be particularly prone to catch a cold, which will reduce your body's resistance and create opportunities for the invasion of various cold viruses.

Is the air conditioner blown up or down in summer?

The explosion is to save electricity. Because the air conditioner cools in summer, the air conditioner emits cold air, and the proportion of cold air is greater than that of hot air. When blowing the air conditioner, adjust the air outlet to the upward position, so that the cold air will circulate from top to bottom, with better refrigeration effect, faster indoor temperature drop and natural power saving. At the same time, blowing the air outlet of the air conditioner upward in summer can prevent the air conditioner from blowing directly to people, and to some extent, it can also prevent the cold air from blowing to cause dizziness, headache, joint icing, rheumatism and other uncomfortable symptoms. Suggested sleep mode. After the sleep mode is started, if the air conditioner is in the cooling mode, when the indoor temperature reaches the set temperature or runs 1 hour, the temperature will automatically rise 1 degree. Run for another hour, and the temperature will rise by 1 degree. When the total running time reaches 8 hours, stop running, that is, increase 2 degrees within 8 hours; If the air conditioner is in heating mode, it will automatically adjust to the human comfort of about 278 degrees, which saves electricity and is not easy to catch a cold.

How to cut off air conditioning in duplex buildings

; ? For people with large rooms, there are actually many ways to cut off the air conditioner, and curtain cutting off the air conditioner is one of them. If you don't know how to turn off the air conditioner in a big room, you can look at the detailed introduction brought by Interesting Ding.

How to block the air conditioning in the big room?

1, separated by gauze curtain, on the one hand, it can block some wind, on the other hand, it also has good decorative effect;

2. Decorative cloth partition is adopted to prevent air flow to the maximum extent, and the windproof effect is better;

3. With the glass partition, a large room can be divided into several small spaces by glass, achieving good refrigeration effect.

Can the curtains turn off the air conditioner?

Can play a certain role in blocking.

The air conditioner operates in refrigeration mode, and the fabric curtains are closed when the doors and windows are closed, so there is relatively stagnant or slow-moving air between the fabric curtains and the windows. This part of the air has a good heat insulation effect on the indoor temperature field; Its working principle is similar to the principle of using double-layer glass windows to keep warm.

When using air conditioning, close the doors and windows as much as possible, and close the curtains when necessary, so as to reduce the heat exchange between the indoor low-temperature site and the outdoor high-temperature site and reduce the loss of indoor refrigeration. When turning on the air conditioner, it is best to put a basin of water in a suitable place indoors. On the one hand, water evaporation can absorb some heat, on the other hand, it can also increase the humidity of indoor air. Open doors and windows regularly for ventilation to ensure the oxygen concentration in indoor air.

What does the air conditioning partition curtain do?

Curtain separation effect is there, but the effect is not very good. All curtains will not absolutely block the airflow, but can only be relatively reduced. Therefore, it is recommended to use gauze curtains. First of all, they can block some wind and have a good decorative effect. If it is necessary to prevent air flow to the maximum extent, it is best to use decorative cloth, which is better on the windshield.
