Why is it so cool outside, but how hot is it in the room?

One is that your house is well insulated, and the other is that you may not have doors, windows, ventilation, and ventilation for indoor and outdoor air to communicate. For example, in this season, if the sun outside is not so strong and cool, you can open the doors and windows for ventilation, so that the interior will definitely be cooler.

Because: the room is closed and the windows are closed, the air does not circulate, or the heating is forgotten.

If you want the room to be as cool as it is outside, you must open the doors and windows for ventilation.

Because the air outside moves fast and there is water vapor.

The air flow outside is of course cool, and the room space is small.

In summer, the outside temperature is very high during the day, and the walls of the house are heated by the scorching sunlight and air to absorb a lot of heat; As the sun sets, the outdoor air temperature drops relatively quickly at night, but the heat absorbed by the house during the day is not released so quickly, and it is still slowly released at night. At the end of the night, the indoor temperature has not reached the same as the outside, and the next day the sun rises again, continuing to heat the outdoor air and the house, and the indoor is still hot. So summer is hot.

I think it's a matter of heat exchange, outside, the heat in your body is absorbed by the air around you and quickly exchanged; Indoors, space is limited, and heat exchange is not as fast and efficient as outdoors, so it will feel hotter.

The house can't be completely open on all sides, and the wind direction is also problematic, unless your house is surrounded by windows, it will definitely be affected by the walls and wind direction.

Even if the house is ventilated, it's still not as good as the outside, and the outside is definitely better than the inside, and there are trees outside, which can take away the heat.

The space in the room is limited, and with various electrical appliances dissipating heat, it is naturally not as cool as outside.

The house is used to protect from the wind and rain. Do you want to live in a house with walls equal to no walls?

After all, the room space is limited, unlike the outdoors.

Because the computer is too hot.

There is no convection in the air in the room. The exterior wall of the room may be a place where the sun often hits and the temperature is high.

High additive heat loss is small. According to the design requirements of the "Technical Regulations for Ground Radiant Heating", the surface temperature of the room shall not be higher than 28 for a long time, and the change law of room temperature in the vertical direction of the room when using ground radiant heating.

The surface temperature approaches 30 and the vertical temperature begins to decrease, reaching the interior design temperature in the human breathing zone. The temperature in the vertical direction at 30 cm above the ground does not change much. When radiant ground heating is used, the temperature of the radiant heating ground is higher than the space temperature.

Technical features:

1) Reduce the temperature of the interior design and save energy consumption. When using low-temperature hot water ground radiant heating to indoor heating, the heat is mainly transmitted in a radiant mode, and the radiant heat dissipation accounts for 50% 60% of the total heat dissipation.

Therefore, floor heating can be used at a lower interior design temperature to achieve a heating effect with a higher interior design temperature of the radiator. The reduction of the interior design temperature means that the indoor heating heat load is reduced, that is, the heating energy consumption is saved, and the energy is saved.

2) Behavioral energy saving and energy reduction.

First, the radiant heating method has a higher thermal efficiency than the convection method, and under the same comfortable conditions, the indoor calculated temperature can generally be lower than that of the convection heating method2 3.

Second, the ground radiant heating is easy for a single household to form its own system, and only need to install a heat metering device next to the water separator to realize the heat metering of the household, which adapts to the change of heating mode, can supply and demand on demand, and realizes energy saving.

Third, after the use of automatic compartment temperature control, the temperature control system can automatically shut down the loop, reduce heat waste, and some data believe that it can save about 10% of energy. Therefore, intelligent floor heating, household metering, and automatic temperature adjustment can achieve behavioral energy saving.

This is also the case in my house, the living room and the room are facing south, but the room is hot, the living room is cool, my room is facing south, the bedroom is sieve directly from the south every day, the sunshine time can last from 8:00 in the morning to 6:00 in the afternoon, it must be hot, and the living room is in the north of the bedroom, the sun is not shining, and the door is opened after ventilation, so the living room is very cool.

I now close the bedroom windows and close the curtains every day before I go, and when I come back, I mop the bedroom and living room with a wet mop and feel much better.

v Put a basin of water in the room during the day.

Hello, I'm glad to answer for you There may be the following reasons why your room is much hotter than outside in the summer:1Poor insulation:

If your room is poorly insulated, outside heat can get inside, causing the indoor temperature to rise. For example, if your room doesn't have enough insulation or your windows are poorly sealed, heat can penetrate into the room. 2.

Improper shading: If your room doesn't have good shading, such as blinds, curtains, or blinds, direct sunlight can enter the room, causing the indoor temperature to rise. 3.

Air Conditioning Issues: If your air conditioner is not used properly, such as setting the temperature too high, the air conditioner filter is dirty, or the air conditioning system is malfunctioning, it will not be able to effectively lower the indoor temperature. 4.

Indoor electrical devices: If you use a lot of electrical appliances in your room, such as computers, TVs, lights, etc., these devices will generate heat, causing the indoor temperature to rise. If you want to cool down your room, consider taking the following steps:

1.Install insulation or replace windows to improve the insulation of your room. 2.

Install shading features, such as curtains or blinds, to reduce direct sunlight. 3.Use air conditioners, but make sure they are used and maintained properly.

4.Reduce the use of indoor appliances, or use low-power, high-efficiency appliances.

The reason why the house is stuffy 2The unit is small. If it is because the area of the house is too small, and the layout of the house is relatively tight, it is easy to give people a feeling of being small and depressed, and then feel that the house is stuffy.

3.Poor ventilation. In a closed space, it is easy for people to feel chest tightness and reduce the oxygen content of indoor air.

people's needs. 4.How to deal with the stuffiness of the house 5

This can be improved with the help of humidifiers, fresh colors and soft furnishings, and it can also make people feel comfortable, so as to reduce stuffiness. The spine of the humidifier will only be effective if it is left open for a long time.
