Why are some houses colder indoors than outdoors in winter no heating and air conditioning indoors

We know that outdoor temperatures change fast. For example, it is cloudy in the morning.

The temperature is only 5 degrees; The sun rises in the afternoon.

After two or three hours, the temperature can reach 10 degrees.

The change of temperature is delayed indoors compared with outdoors, which is reflected in the fact that the change amplitude is smaller than that outdoors. When the outside temperature rises by 5 degrees in a day, the indoor temperature also rises. So, it's colder indoors than outdoors at this time.

The reason why there is a delay in the change of indoor air temperature is because:

1.Indoor and outdoor are not integrated, the rise and fall of outdoor temperature is mainly affected by doors and windows, and the rise and fall of indoor temperature should be slower.

2.interior walls, ceilings.

Floors, furniture, etc., can absorb or release heat. When the outdoor temperature rises, part of the heat entering the room will be absorbed by walls, ceilings, floors, furniture, etc.; When the outdoor temperature drops, part of the cold air entering the room will be offset by the heat release from the walls, ceilings, floors, and furniture; Indoor air temperatures rise or fall in a slow process.

In the same way, when the outdoor temperature drops rapidly, the indoor temperature drops later. At this time, it is warmer indoors than outdoors (there are no heat sources such as heating and air conditioning indoors).

Only when the outdoor air temperature remains warm or cool for several consecutive days, the indoor air temperature can gradually rise or fall close to the outdoor air temperature.

Is it that the room is just on the north side, and the south side is blocked.

For many families, even if the air conditioner is turned on indoors in winter, it still feels unwarmThe main reason is that the temperature of the air conditioner is always floating above.

Because the hot air is relatively light, and the cold air is always stored in the lower part, so we don't feel very warm, so to solve this problem, we need to buy electric heaters, although the heat of the electric heater will also float above, but the electric heater is placed under the feet, so the whole house will become unusually warm.

However, the electric heater is abnormally expensive, and a 2 kilowatt electric heater will consume at least 30 yuan of electricity at nightBut if there are children at home, no matter how much money you spend, you have to do it, if the child is sick because of the cold, then the gains really outweigh the losses, in fact, friends in the north are still very good, at least there is heating in winter.

And now most of the family, especially the old-fashioned heating, due to the aging of the heating pipes, even the heating can not reach an average temperature point, in the face of such a situation, the best way to deal with it is to change the vertical old-fashioned heating to geothermal heat, of course, before the modification must be to the local heating department to contact, but also under the supervision of the property to complete.

Generally speaking, after changing the geothermal heat, the temperature in the house should rise at least between 5 and 10 degrees, because the geothermal heat is a full-coverage heating without dead corners. Of course, there is another reason, that is, there are gaps in the aging windows in the house, which causes cold air to pour into the house, even if the temperature in the house is high, it will be reduced, so those aging doors and windows should be replaced in advance. Especially for the kind of plastic steel windows, the rubber strips will age and deteriorate after about 5 years, so the plastic steel windows must be replaced every few years.

It may be that the heating effect of the air conditioner is not good, you can find a maintenance person to repair it, or it may be that the house is too big.

The main reason is that the hot air is lighter and floats above, while the cold air stays in the lower part all the time, so we don't feel very warm.

It may be that the home is too cold, the air conditioner cannot be supplied, and then the house is particularly breathable, or it may be that the air conditioner is aging.

Because the hot air runs upwards, it will not feel warm, and there is also the aging of the sealing strips of doors and windows, which causes gaps and air leakage.

It may be that you have to have a broken electric heater, check to see if the machine itself is broken, or if the connector is not plugged in properly.

Is it possible that my own problem is not good, and I feel that even in summer, my hands and feet are always cold and uncomfortable.

It could be that the house is too old, or the air conditioner is not warm enough, or the windows are open.

The heating effect of the air conditioner is not good, or the sealing condition of the home is too poor.

If the size of the air conditioner is selected correctly, it means that the air conditioner is lacking refrigerant.

Thermal insulation - that is, thermal insulation. Reduce indoor-outdoor temperature exchange. The walls are covered with insulating panels (interior or exterior walls), and the exterior wall that is exposed to the sun in the summer is shaded.

Use double glazing with airtight air in the middle. The doors and windows are tightly airtight (when closed, you must be able to clamp a piece of RMB without falling off, and if it can fall, it means that your RMB will consume air conditioning due to ventilation through the gaps.) plus ceilings.

The ceiling and roof are insulated with thermal insulation materials. It's best to ventilate the space above the ceiling. All of this has to be seamless.

I'll give you a ** look at how to insulate the exterior walls of houses in the United States. 12 mm thick foam laminate • The entire exterior wall of the house, the gap between the glue board is tightly attached with wide tape.

Yes! Sold it and bought a new building.

You ask others to be detailed, but your question is not detailed at all. You don't provide the outdoor ambient temperature when you compare the room temperature, for example, if your hometown is at the equator and you live in Antarctica, then the house in your hometown must be warm!

Let's assume that the outside temperature is the same in both places. I can't fully believe your feelings, because feelings are unreliable, and you should use a thermometer to actually measure whether the temperature is different between the two places, and what is the difference. You have to know that a small temperature difference is possible and inevitable.

If you believe that your feelings are right, one is cold and the other is hot, so is it at a point in time when you "feel the temperature"? You should know that although it is the same winter, some winters are cold, and some winters are a little warmer, which is different from the climate every year. Even in the same winter, the temperature is different at different times.

For example, January is the coldest month, and the other months are warmer. Even if it is the same month, then the indoor temperature is different at different times of the same day in the same month in winter (since there is no heating), it is warmer at noon and colder in the evening.

In addition, it has to do with the amount of clothes you were wearing, the yin and yang of your mood, and the yin and yang of the weather, and there is another reason that cannot be ignored, that is, the humidity of the two places. A 10% increase in humidity would result in a 1 degree Celsius difference in human perceived temperature (although the measured temperature was the same). Because moisture will penetrate the clothes, reach **, and take away the heat.

In short, your question is very vague and does not provide any data, and such a question cannot be analyzed and answered by specific theories. I have given you a comprehensive explanation of the background of your question and the reason why there is no answer, please give me one.

The heating is different in various places, although the money is the same, and the stove also needs to be diligent enough.

A1It has to do with the materials used to build a house. In the past, the old houses in the countryside used earthen walls, which would be warm in winter and cool in summer, and now, more environmentally friendly and energy-saving products are used, so the energy-saving performance of the building is good, and the effect of warm in winter and cool in summer can be realized.

Insulation of windows and doors alone is not enough, and exterior walls are also very important. In the eastern part of Shandong Province, there is a new type of house-building technology, which hollows out the ground and puts firewood and grass, which is lit in winter, and can be used for 3 to 4 months; There are pipes installed on the wall to cool down in the summer. It can achieve the effect of warm in winter and cool in summer2

The house is warm in winter and cool in summer, which is related to the external wall structure of the house. The surrounding planting is not the root cause. Nowadays, the design of houses is to add an insulation layer to the inside of the exterior wall, which literally means that it is used for thermal insulation in winter, but in fact, there is also a role in summer insulation.

But now many construction parties in the process of building a house to change the design of the design are directly omitted, and China's current housing in the completion of the acceptance of the acceptance of the aspect of the acceptance of the acceptance of the aspect, so, when buying a house, can only choose the construction reputation is good, large construction companies and professional supervision companies to supervise the project.
