When the temperatures rise outside, many apartments quickly turn into heat chambers. Air conditioning could remedy the situation – but is often expensive, loud and energy -hungry. There are numerous simple ways to keep rooms pleasantly cool even without high -tech.
Ventilate early, then everything is tight
In the early morning, the air is fresh. If you then ventilate – i.e. opens windows on opposite sides, you can optimally bring the cool air into the house. After that, it says: windows too, roller blinds down and leave the heat outside. The ENBW energy supplier confirms that rooms remain noticeably cooler during the day.
Leave the sunlight outside
Direct sunlight ensures that rooms literally heat up. Remedy to remedy roller shutters, blinds or curtains, preferably in bright colors or with a reflective back. External shading systems, such as folding shops or awnings, are even more effective. Klimatechniker.net emphasizes that the heat is stopped in front of the window.
Switch off technical heat sources
Many devices that hardly notice in everyday life develop a surprisingly large amount of warmth in the company. TV, router, laptops – they all contribute to the fact that the room air is additionally heated up. It is therefore advisable to completely switch off devices that are not required instead of running them in stand-by mode.
Use fans sensibly
A fan does not ensure cooler air directly, but conveys a more pleasant feeling through air movement. It becomes really effective when you present a bowl of ice cubes or a frozen water bottle. According to Better Homes & Gardens, this creates a refreshing air flow that looks like a small, self -made air conditioning system.
Moist cloths bring freshness
A tried and tested trick: wet sheets or towels in front of the open window. The evaporating moisture removes warmth of the air and acts like natural air conditioning. A too high humidity should be avoided, since the cooling effect subsides when the weather is mandatory. As a result, the water can then evaporate less.
Cool nights with the “Egyptian Method”
Originally known from hot regions, a simple method has also proven itself here. Instead of under the normal duvet, according to the evapolar, you lie under a slightly moistened sheet. As the water evaporates, a cooling effect arises.
Retrofit outdoor shading
Shadow is the simplest coolant. Whether through a sun sail, a tree or a pergola – the less sunlight meets the window areas, the less the interior heats up. Klimatechniker.net points out that good external shading can make the difference, especially on western and south facades.
Plants act like natural air conditioning
Housing plants can be more than just decorative. They increase the humidity and ensure a slight cooling effect due to evaporation. According to Emero, large -leaved plants such as rubber trees or ferns in particular help to improve the indoor climate noticeably.
Light colors keep warmth away
Dark textiles and surfaces take up light and heat particularly strongly. Anyone who relies on bright fabrics, furniture and wall colors in summer reduces the warming up. A light, airy furnishings can not only worry more, but also functionally.
Adjust the ceiling fans correctly
A common mistake in ceiling fans: they turn in the wrong direction. In summer, the air flow should be directed down – i.e. against clockwise. This ensures that the cooler air circulates better in the room. Emero recommends to change the rotation sense depending on the season.
Cook when it gets cooler outside
The stove, oven or tumble dryer generate a lot of warmth in operation. If you prepare your meals in the early evening or late in the morning when the outside temperatures are lower, you prevent the room from heating up unnecessarily.
Tinker small cooling devices yourself
A fan, a metal bowl and ice cube – more is no need for effective DIY cooling. The air flow strokes the ice and transports the cold into the room. According to Homes & Gardens, this method works particularly well in small rooms or directly at the workplace.
Design heat specifically
Heats can stow over days, especially in attic apartments or poorly insulated buildings. The Federal Environment Agency recommends to ventilate extensively in the cooler night hours – preferably supported by a fan that blows warm air out of the window. This can effectively escape the stored heat.
