    3. Text «Ventilation and Air Conditioning ».

    Ventilation – the exchange of indoor air with outdoor air – is important to reduce indoor moisture, odours, and other pollutants. Contaminants such as volatile organic compounds, and radon (that may cause health problems) can accumulate in poorly ventilated homes. Excess moisture needs to be removed before high humidity levels lead to physical damage to the home. There are three main types of ventilation: Natural ventilation which is uncontrolled air movement through cracks and small holes (infiltration) and through vents such as doors and windows. The disadvantage of this is that it is uncontrollable. Spot ventilation which means using localised fans in the rooms where contaminant substances are generated (for example kitchen extractor fans and bath fans). Whole-house ventilation is a system that works thanks to fan and duct systems to exhaust stale air and supply fresh air to the house. Whole-house ventilation systems are usually classified as exhaust ventilation when the air is forced out of the house, supply ventilation if it is forced inside and balanced ventilation if the same amount of air is forced inside and outside the house.

    Air conditioning is the process of altering the properties of air (primarily temperature and humidity) to more comfortable conditions, typically with the aim of distributing the conditioned air to an occupied space to improve thermal comfort and indoor air quality. In common use, an air conditioner is a device that lowers the air temperature. The cooling is typically achieved through a refrigeration cycle, but sometimes evaporation or free cooling is used. Air conditioning systems can also be made based on desiccants. In the most general sense, air conditioning can refer to any form of technology that modifies the condition of air (heating, cooling, humidification, cleaning, ventilation, or air movement). However, in construction, such a complete system of heating, ventilation, and air conditioning is referred to as HVAC.

    2. Мәтін аудару «Air Conditioning».

    Modern air conditioning emerged from advances in chemistry during the 19th century, and the first large-scale electrical air conditioning was invented and used in 1902 by American inventor Willis Carrier. The introduction of residential air conditioning in the 1920s helped enable the great migration to the Sun Belt in the United States. Air-conditioning is the bringing of air in a building to a desired temperature, purity, and humidity throughout the year to maintain healthy Air conditioning units outside a building Window unit inside a room 90 and comfortable atmosphere. Air-conditioning may be divided into two main sections: one for the processing of materials in industry, the other for human comfort. Air-conditioning provides the following services: 1. Filtration of the air both in winter and summer to remove dust. 2. Circulation of the air at low velocity and with proper diffusion to prevent draughts and maintain a uniform temperature and humidity at all parts of the inhabited space. 3. Introduction of enough fresh air from the outside atmosphere. 4. Heating of the air in winter. 5. Cooling of the air in summer below the outside atmosphere. 6. Humidify the air in winter to a relative humidity of at least 20-25 per cent. 7. Dehumidify the air in summer to a relative humidity not exceeding 55 per cent.
