How much is the appropriate degree of air conditioning heating in winter

In the hot summer, we have to consider the problem of air conditioning and refrigeration; in the cold winter, we have to focus on the problem of air conditioning and heating. Unlike air-conditioning and refrigeration, most air-conditioners are affected by the outside environment temperature when heating. Generally, the lower the outside temperature, the lower the heating effect of the air-conditioning. If you blindly increase the air-conditioning temperature, it will not only waste energy but also It is easy to shorten the service life of the air conditioner. How many degrees is suitable for the heating of the air conditioner in winter? Experts from Shanghai Yuanhui Construction said that we cannot control the ambient temperature, but we can start from the temperature of the air conditioner. The heating degree of the air conditioner is better divided into the following forms.

How much is the air conditioning heating degree better-the human body comfortable temperature

From the perspective of human comfort, it is appropriate to control the indoor temperature between 18 degrees Celsius and 20 degrees Celsius in winter, because in winter, people wear more clothes. If the indoor temperature is higher than 20 degrees Celsius, it will feel a little hot. If the air-conditioning temperature is set higher than 26℃ in winter, the heating temperature in winter will be too high, which will cause the indoor air to be extremely dry, harm human body fluids, body fluids, and make people feel hot and dry in the eyes, ears, nose, nose, and throat. .

How much degree is better for air-conditioning heating-health care temperature

From the perspective of health care, when using air conditioners in winter, you should pay attention to at least two issues: First, the temperature difference between indoor and outdoor should not be too large. In winter, the air conditioner temperature setting is better to keep the indoor 8 degrees Celsius higher than the outdoor. If the temperature difference between indoor and outdoor is too large, people are prone to catch colds in a sudden cold and hot environment. For the elderly and people suffering from high blood pressure, the temperature difference between indoor and outdoor cannot be too large, because the indoor temperature is too high and the human body’s blood vessels relax. At this time, if you suddenly go outdoors, the blood vessels will contract suddenly, which will cause the cerebral blood circulation of the elderly and hypertensive patients to become obstructed, which will easily induce stroke. Secondly, closing doors and windows when the air conditioner is turned on will cause indoor hypoxia, bacteria, Viruses will also take advantage of the opportunity to accumulate in large numbers. Therefore, the air conditioner should be stopped every time the air conditioner is turned on for more than 2 hours and the window should be opened for ventilation. Shanghai Central Air Conditioning

How much degree of air-conditioning heating is better -20℃ is suitable

We know that the air-conditioning temperature in summer is suitable at 26°C-28°C, and the best temperature setting for air-conditioning in winter is 20°C. Overheating indoor temperature is not only good for your health, but also avoids overloading of the air conditioner. For friends who like to increase the indoor temperature, please be careful not to set the temperature at 30°C that the air conditioner can withstand in winter, otherwise it will cause the air conditioner to start frequently or Non-stop, increase power consumption, and even damage the air-conditioning compressor in severe cases.

How much is the air conditioning heating degree better-every 2 ℃ lower than the energy saving 10%

In winter, every time the air conditioner temperature setting is lowered by 2℃, the air conditioner can save more than 10% of electricity. From the point of view of energy saving, the lower the air conditioner setting temperature can ensure the human body heating, the better. Therefore, considering many factors, it is recommended that the air conditioner temperature setting in winter should be around 20℃. In addition, because The heating flow is lighter than air, and it is easy to float above the entire enclosed room. When using a wall-mounted air conditioner, it is better to adjust the air outlet to a downward angle, which can save electricity.

The air conditioner has a better heating degree, and the best temperature setting for the air conditioner in winter is 20°C. When the outside temperature is below minus 5 degrees, the air-conditioning heating cannot be started at all. When we are not controlled by the external environment, our experts remind consumers to have a full understanding of their air-conditioning and understand the heating of the air-conditioning in winter. How much is appropriate to wait for relevant knowledge, so that when you encounter problems, you can easily solve them.
