The internal atmosphere of the home is influenced not only by the situation in the middle of the house and the interior, invented by the owners but also by the physical indicators of temperature, humidity, and cleanliness. These indicators form the home microclimate. For it to be pleasant and healthy, it must be maintained at an optimal level.
Home microclimate parameters
The parameters that determine the microclimate of residential and public buildings are as follows:
- air temperature;
- air exchange (ventilation);
- freshness and purity of air.
The microclimate of the house is formed from the listed parameters and is responsible for the durability and preservation of a construction. If the indicators of the microclimate are outside the optimal level, the floor in the house may dry out and creak from dryness, or, conversely, moisture can accumulate in the windows, destroying expensive window boxes and forming fungi with toxic evaporation. That is, an imbalance in the parameters of the microclimate in the house can greatly harm human health, cause suffocation, fatigue, and severe discomfort. To avoid this, the microclimate must be maintained at an optimal level.
Sanitary and hygienic norms of living quarters determine the optimal air temperature of 70°F at a humidity of 40-60%. Such conditions are considered the best for the human respiratory system. It is known that during epidemics of influenza or coronavirus, people who spend most of their time in conditions of optimal humidity, get sick much less often. The allowable minimum temperature in the house in winter should not fall below 64°F. The best temperature in the bedroom during sleep is also 64°F. In addition to humidity and temperature, below we will consider in detail the other parameters of the microclimate.
How to regulate the parameters of the microclimate?
Taking into account that the home has different functionality, in the kitchen, for example, it is necessary to maintain 66-70°F, as the operation of the toaster, coffee maker, microwave or oven increases the temperature in the room. And in the bathroom, the humidity is always high, here the recommended temperature is 75-79°F to avoid humidity. The child room should be maintained at about 73°F.
How is it measured? Thermometer or sensors of the heating system.
How is it regulated? With the help of heating and air conditioning systems.
Optimal humidity for humans – 40-60%. Permissible humidity in the house is in the range of 30% to 65%. If the percentage of humidity is lower, there may be dryness of the skin and mucous membranes (eyes, respiratory tract). It is very harmful to asthmatics. If the percentage of humidity is higher than this, the room can develop mold and fungus, leading to infection by fungal organisms and weakening the immune system.
How is it measured? You can use a household hygrometer. In some cases, humidity is measured by sensors of the intelligent microclimate system.
How is it regulated? The humidifier will help to cope with the lowered level of humidity. There are steam or ultrasonic humidifiers. Also, in the case of low humidity in the house, it is recommended to carry out frequent wet cleaning. High humidity is a more serious problem. It must be adjusted with a ventilation system, insulation of freezing structures, and elimination of leaks.
Air exchange (ventilation)
How is it measured? It is difficult to determine this value on your own, so it is recommended to pay attention to your feelings.
How is it regulated? With regular ventilation and an efficient ventilation system.
Dust, exhaust gases from an open window, evaporation of finishing materials in an interior, the fur of pets constantly gets into the air. With such particles, viruses and bacteria enter the room. It is logical that to maintain an optimal microclimate in the house should be a minimum of harmful microorganisms in the air.
How is it measured? It is not measured at home, only in a chemical laboratory.
How is it regulated? Using the filter of supply ventilation. The air is also well cleaned by special cleaners-disinfectants that kill bacteria.
It is determined by the carbon dioxide content. The optimal CO2 content is 800 ppm. The growth of this indicator can lead to fatigue, lethargy.
How is it measured? The amount of CO2 can mainly be measured by special sensors in intelligent microclimate control systems.
How is it regulated? Regular ventilation, along with effectively configured supply and exhaust ventilation, will help freshen the air in the room.
