The basic of HVAC
Introduction.
The modern commercial or office building consis of many sophisticated system. These systems in clude foundation and support structures. Electrical and lighting & plumbling & fixtures another major part of any building that is often taken for granted by its inhabitants is the h-back system a track stand for heating, ventilation and air conditioning.
In this unit we will identify the purpose and goals at the age back system describe basic age back parts and describe how these parts work together. Air quality is an essential consideration in maintaining the productivity comfort and health of the occupants and should not be trivialized. If air quality and temperature are not maintained. Occupant comfort in the workplace can suffer directly affecting productivity and morale.
The Goals of an HVAC System
When examing the designer been a track system we must remember the various roles at the age back system plays we all know that when we’re cold we turn the thermostat up for more heat and when we’re hot we turn the thermostat down. So the h-back system keeps us comfortable by adjusting the room’s temperature, but equally important the h-back system must keep occupants comfortable by supplying fresh heir to a room if we introduce a significant carbon dioxide buildup occupant experience better health and performance gains. Studies have shown a direct link between 〖Co〗_2levels and short term sick leave in office work forces however our concerns regarding the h-back system and occupant health do not and here in heavily. Air-conditioned energy efficient environments recirculated condition air can carry contaminants which contribute to respiratory illness it is the age back systems job to remove contaminants and dust from the air using filters at various stages as important as this consideration is in an average officer commercial building. This feature is critical in facilities that contain clean rooms medical facilities poor hazardous materials. Finally with the spiraling cost of fuel h-back systems must also be efficient and economical energy-efficient h-back systems might incorporate. Valuable air volume designs components designed for operation at low pressures digital control systems mechanisms for reclaiming heating or cooling benefits from recirculated air and high-efficiency ECAM fan motors. Many price products are designed specifically with energy efficiency in mine by understanding the importance of occupant comfort we realize the significance at the age back system in a building design it’s responsible for controlling the temperature in the environment. Providing fresh air to the occupants filtering out Dustin contaminants while operating in an energy-efficient and unobtrusive manner. The following section covers the different parts that make up a basic h-back system once we understand the range of components involved we can better understand the reasons for choosing system component from prices extensive product line-the part have an h-back system the atrack system installed in a commercial or office space differs greatly from the heating and cooling system that you might be familiar with in your house. In your home heating system is set up to deliver warm air during the winter and cool air in the summer it does this using a furnace or an air conditioner and a common set of duct work when your thermostat detect that your home is too cold it sends signals to the furnace which then delivers warm air simultaneously to. All parts of your house note that it is typical to have only one thermostat and it does not account for temperature variation in any other rooms like wise in the summer your thermostat will detect when your home has become uncomfortable warm and it will signal your central air conditioning system to deliver cool air simultaneously to all parts of your house again note that your thermostat is measuring the temperature in only one room the conditions in an office or commercial space are quite different higher concentrations of people and equipment will generate more heat making air conditioning or recirculation affair more important been providing heat although the air handing equipment is centralized different rooms and regions in the building will have different needs for heating and cooling these needs are called loads because they place a load or demand on the h-back system these loads can come from the equipment. People whether and many other factors in the simplest case we address this by providing a constant supply of cool care which is then managed by the age factor distribution system the chiller or air conditioner utilizes heat exchangers and circulated fluid or gas to cool the air that is passed through it. The air that is passed through it. The air handle is a fan or blower that moves air throughout the building’s ductwork actual or centrifugal fan types may be found in the air handle air filters depending on the requirement of the occupant and the a
