In many parts of the country these concerns can easily be addressed by application of basic engineering principles and off- the- shelf hvac equipment. During the heat of the day, heating ventilation and air conditioning book pdf the air usually absorbs moisture.
Quick removal of concentrated air contaminants and building pressurization are two ways that exhaust systems affect heating ventilation and air conditioning book pdf iaq. The main purposes of a heating, ventilation and air- conditioning heating ventilation and air conditioning book pdf ( hvac) system are to help maintain good indoor air quality through adequate ventilation with filtration and provide thermal comfort. Air heating ventilation and air conditioning book pdf conditioning two general types of air conditioning ( cooling) refrigerant- based: refrigeration cycle moves heat from one space ( indoors) to another ( outdoors) refrigerant evaporates and condenses continuously within cycle refrigerant has a low boiling point, making heating ventilation and air conditioning book pdf it ideal for hvac systems similar to car ac system. However, it is more difficult to assure proper maintenance heating ventilation and air conditioning book pdf of multiple units over time and they present additional opportunities for moisture problems through the wall penetration and from drain pan and discharge problems. Air conditioning can be used in both domestic and commercial environments. Heating, ventilation and air- conditioning ( hvac) energy code requirements the heating ventilation and air conditioning book pdf energy requirements of the building code that apply to hvac instal- lations ( ecccnys section 503) are in addition to any plumbing, heating ventilation and air conditioning book pdf mechan- ical, and fuel gas codes that apply to these systems. The most effective means of reducing exposure of occupants to gases and vocs is to manage and control potential pollution sources. Unit ventilators and heat pumps have the advantage of reduced floor space requirements and they do not recirculate air between rooms.

Hvac system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics and heat transfer. Figure 1- heating ventilation and air conditioning book pdf 1, a heater, ventilation and air conditioning ( hvac) system can be divided into the following three sub- systems:. In spaces where the number of occupants is highly variable such as gyms, auditoriums and multipurpose spaces, demand controlled ventilation ( dcv) systems can be used to vary heating ventilation and air conditioning book pdf the quantity of outside air ventilation in these spaces in response to the number of occupants. Filters are available to remove gases and volatile organic contaminants from ventilation air; however, because of cost and maintenance requirements, these systems are not generally used in normal occupancy buildings or schools. Yet there are concerns over the implications that this added amount of outdoor air supply has on the first cost and operating cost of the hvac system, as well as moisture control for the school ( too wet or too dry). At a minimum, the following components should be labeled in each ventilation zone of the school and should correspond with the hvac diagrams and drawings. However, the very properties that make duct board and duct liner superior insulators heating ventilation and air conditioning book pdf ( e. Although there are many different types of air handling units, for general iaq implications in schools, air handling units can be divided into two groups: unit ventilators and individual heat pump units that serve a single room without ducts; and central air handling units that serve several rooms via duct work.
