HVAC

HVAC (heating, ventilation, and air conditioning) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. Refrigeration is sometimes added to the field’s abbreviation as HVAC&R or HVACR, or ventilating is dropped as in HACR.

HVAC is important in the design of medium to large industrial and office buildings such as skyscrapers and in marine environments such as aquariums, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.

The main purposes of a HVAC system are to help maintain good indoor air quality through adequate ventilation with filtration and provide thermal comfort. HVAC systems are among the largest energy consumers in buildings. The choice and design of the HVAC system can also affect many other high performance goals, including water consumption (water cooled air conditioning equipment) and acoustics.

The three central functions of heating, ventilation, and air-conditioning are interrelated, especially with the need to provide thermal comfort and acceptable indoor air quality within reasonable installation, operation, and maintenance costs. HVAC systems can provide ventilation, reduce air infiltration, and maintain pressure relationships between spaces.

A modern quality HVAC system should provide an appropriate quantity and quality of outdoor air, lower energy costs, and easier maintenance.

In most developed countries climatic conditions require that outdoor air must be heated and cooled to provide acceptable thermal comfort for building occupants, requiring the addition of HVAC systems. The selection of equipment for heating, cooling and ventilating the building is a complex design decision that must balance a great many factors, including heating and cooling needs, energy efficiency, humidity control, potential for natural ventilation, adherence to codes and standards, outdoor air quantity and quality, indoor air quality, and cost.

Ex. 7. Translate the following texts from English into Russian

Public relations (PR) is a way for companies, organizations or people to enhance their reputations. This task typically is performed by public relations professionals or PR firms on behalf of their clients. PR usually involves communicating with the media and through the media to present the clients in the most favorable way possible. It also often involves cooperative efforts with other people and organizations to create good will within the community and enhance the client’s image.

Image is Important

The business world can be extremely competitive. Companies typically want to have something that makes them stand out from the crowd, something that makes them more appealing and interesting to both members of the public and the media. A favorable image can help increase a company’s sales, and negative publicity can damage a company’s reputation and decrease sales.

PR Departments

PR can give consumers and the media a better understanding of how a company works. Within a company, a PR department might also be called a public information department or a customer relations department. These departments assist customers if they have any problems with the company. They usually try to show the company at its best. PR departments also might conduct research to learn how satisfied customers are with the company and its products.
