Why some houses can be warm in winter and cool in summer

1. The temperature of the house is the same as that of the cave, and there is no change in winter and summer. It is said to be warm in winter and cool in summer because of its good thermal insulation performance. The cave was dug on the hillside, so it's"roof"with"walls"are quite thick.

When people dig caves, they choose places with relatively hard soil, which is thick and hard"walls"It is not easy to transfer heat. Therefore, the roof and wall of the cave can neither directly absorb heat from the atmosphere, nor can it directly dissipate heat into the atmosphere, only the mouth of the cave is in direct contact with the outside world. Therefore, the temperature change in the cave always lags behind the temperature change outside, and the temperature difference does not change much.

2. It is related to the materials used to build a house.

In the past, the old houses in the countryside used to be made of earthen walls, which would be warm in winter and cool in summer.

Nowadays, 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 summer.

There is a river on the left side of my house, there are many trees and wind in summer, and there is a layer of insulation on the house, so it is not very hot in summer, and the ventilation in the home is very good in summer, and the reason for the insulation layer is estimated in winter, which is not very cold.

It is recommended that the house design should have an insulating layer, and the home can be designed with a narrow passage for front and rear ventilation, and there should be plants and trees around it, which is both beautiful and ventilated and can purify the air.

The first condition of an ideal home:

It's the house to be built on a wetland.

There is soil and plants.

The second condition of an ideal home:

It is a person who lives in it and should be able to perceive the changes of the four seasons in spring, summer, autumn and winter.

The third condition of an ideal home:

It's the wind. No matter what kind of new building it is, when the night cools down, the natural wind should be able to enter the building, which is an important condition for a good building.

The fourth condition of the ideal home:

On the premise of ensuring privacy, neighbors can understand and communicate with each other.

Warm in winter and cool in summer? Fool your purse.

The house is warm in winter and cool in summer, and the exterior wall structure of the house is related, and the planting and greening around it mentioned above is not the root cause. Nowadays, the design of houses is to add insulation and layers to the interior of the exterior wall, which literally means 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.

Don't look at the developer's quality or badness, because the developer doesn't care about that. Again, it has to do with the main structure of the house and the attic on the top floor, if you choose the top floor and there happens to be no attic above, that's even worse.

The reasons why the earthen house is warm in winter and cool in summer are good thermal insulation and the material used to build the house is soil.

It has good thermal insulation properties. The cave was dug on the hillside, so it's"roof"with"walls"are quite thick.

Material: In the past, the old houses in the countryside used to use earthen walls, which would be warm in winter and cool in summer.

How to warm up in winter and cool in summer in the building:

1. Fan or ceiling fan.

This is the oldest but most convenient way to cool down.

2. Thick curtains.

The best way to cool down is to keep your house safe from the sun's scorching heat. Therefore, it is very necessary to prepare a thick curtain cloth.

3. Prevent too many electrical appliances from running at the same time.

Many appliances can emit heat, such as refrigerators, lights. If you are still using the air conditioner, it is best not to put large electrical appliances next to the air conditioner.

4. Plants Fallen leaves on the south or west side of your roof can keep your house warm in winter and cool in summer.

5. Roofs and walls.

1. Painting insulation materials on the walls of the building can effectively achieve warm in winter and cool in summer.

In the process of floor construction or renovation, the ordinary cement mortar on the periphery of the whitewashed wall is changed to thermal insulation mortar, and then a layer of anti-cracking mortar is coated, and finally the periphery can be modified, and this thermal insulation mortar is a kind of rubber powder polystyrene particle insulation material.

2. Plant vegetation and expand the green area.

In the middle of summer, the perceived temperature of standing in the sun is completely different from that of standing in the shade of a tree, sometimes even 3-6 degrees Celsius, so don't ignore the role of greenery.

3. Expand the window area and choose dark thick cloth curtains.

The larger the window area, the better the indoor air circulation. In addition, installing external roller blinds on windows and sticking loose film on windows can also effectively regulate the indoor temperature.

4. Ground source heat pump system.

According to Huaxi ***, the installation of a ground source heat pump system in the house can effectively achieve warm in winter and cool in summer. In winter, the geothermal system can use equipment to transport energy from the underground soil to the room through underground pipes; In summer, the cold energy can be transported to the room, so as to achieve the effect of low carbon and energy saving, warm in winter and cool in summer.

5. Temperature-controlled smart glass.

According to People's Daily Online, installing temperature-controlled smart glass in a house can achieve self-service control of indoor temperature and brightness. Temperature-controlled smart glass can change with the change of outdoor temperature, controlling the transmittance of visible light and infrared light. When the outdoor light is strong and the temperature is high, the glass will automatically darken; When the outdoor light is insufficient and the temperature is low, the smart glass can present a completely transparent state, absorbing more light indoors.

6. Let the wall crawl full of creepers.

The creeper is a grape plant that is not afraid of bright light and climbs to grow. In summer, the foliage is dense and covered on the walls of the house, which can not only beautify the environment, but also absorb noise and dust pollution in the environment; In the hot summer, the dense branches and foliage of creepers can block the strong sunlight, thereby reducing the indoor temperature; In the cold winter, the branches and leaves of the creeper wither, the wall absorbs light, and can increase the indoor temperature, so as to achieve the effect of warm in winter and cool in summer.
