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 activities in the building various grades have air filters are used in the system general-purpose air filters will be included in the air handle itself while more sophisticated filters such as happen filters may be used in the downstream ductwork. Round square and rectangular duct work provides a pass for the condition air from the air handing unit to the environment a damper consists of one or more blades which can be used to control the amount of airflow through adopt manual dampers are used to ensure that different part of the building receive proportional ventilation based on area and demand automated dampers may be installed at firewalls which clothes in the case of a fire a terminal unit is a device that uses an automated damper to control the amount of air. which is delivered to a room or region the damper is typically controlled by an electric pneumatic or digital actuator which in turn is regulated by a thermostat a set up a Jason rooms or regions in a building. Which have identical heating and air conditioning needs are at least one terminal unit and corresponding thermostat to each zone price manufactures many different varieties of building needs we discuss terminal units in greater detail in the forthcoming terminal unit section heating coils may be installed after a terminal unit to provides heat honors on by his own basic as mentioned previously building with a high number of occupants may not require extensive heating even during the coldest months of the year heating coils offer an efficient way of providing he’d for those few areas that require it and are controlled by the same thermostat system as the terminal unit various types have lining are available to dampen noise within a dot a short length have lined up at work called an attenuator is often installed following the terminal unit to dampen discharge noise ultimately the test have an h-back system lies in its ability to deliver conditioned air to the occupant air from the ductwork enters the occup
