The condition of the air conditioner should be monitored , and it is not always possible to change filters or clean the equipment yourself - often you have to call the master. Otherwise, the air conditioner from a friend can turn into the worst enemy. All, probably, heard about the "Legionnaires' Disease" (a rare type of pneumonia). Bacteria Legionella (Legionella pneumophilla) - pathogens - live not only in open water, but also in air conditioning and forced ventilation.
Cultivate creepers. Wild grapes and ivy can protect the house from the heat. Grapes are grown on special grids, arranged in such a way that they, giving a shadow, do not block the access of cool air and do not create excessive humidity.
Provide shade with the help of shrubs . Fast-growing hedges will help to shade the patio and access roads well. Vegetation creates a cool microclimate, and the temperature in your home can still drop substantially. Shade the roof of the house can be, growing tall, with wide crowns of deciduous trees on the south side.
The shadow created by one tree is capable of giving a cooling effect to five air conditioners.
Shading the window can delay up to 40% of the summer heat. Curtains, shutters or louvered light colors will help reflect sunlight. Use thermal reflectors (deflectors). Think about installing sheds, shutters or reflective films on windows from the sunny side.
Take care of the roof
About a third of the unwanted heat in the summer comes to your house through the roof, so think about how to isolate the attic from the rest of the house. Use a heat reflective coating. Acquire a metal foil reflecting the thermal radiation. The air temperature in the attics in the summer can reach 65 ° C. By installing a reflective foil (sold at home appliances stores), you can lower the temperature in the attic to 30-40 ° C. Stopping the air leak and isolating the attic from the rest of the house leaves hot air at the top.
Add moisture
If you live in a dry climate, think about purchasing a steam-generating cooler equipped with water-saturated gaskets. Such a device cools the air by 5-10 ° C (warm air exits through the windows). This vaporizer uses three times less energy than the central air-conditioning.
Road to the winds
Open the windows in the ground floor with a windy side and on the top floor on the opposite side to create a draft. Your house will "work" on the principle of a chimney-the cold air enters from below, the warm air comes from above. If there is no wind, create it with a window or ceiling fan. Think about a general-purpose fan. If you live in a climate where at night it's cool, you can come in handy home fan, which, drawing cool air through the windows, then releases it through the roof. For installation you will need the help of a specialist.
The direction of air flow from the fan should be adjusted downwards. The ceiling fan needs to be turned off when leaving the room - it cools the person, but not the room.
Get rid of internal heat sources
It would seem, what a trifle - a normal light bulb. But it is worth bearing in mind that traditional incandescent lamps not only shine, but also heat - transform up to 90% of their energy into heat. Replace them with compact and economical fluorescent lamps.
Give rest to household appliances. Even being in the standby mode (low power consumption), they produce heat, they heat up. In the heat, avoid using microwave ovens, ovens, dryers.
