Heating, Ventilating, and Air Conditioning (HVAC) equipment perform heating and/or cooling for residential, commercial or industrial buildings. The HVAC system may also be responsible for providing fresh outdoor air to dilute interior airborne contaminants such as odors from occupants, volatile organic compounds (VOC’s) emitted from interior furnishings, chemicals used for cleaning, etc. A properly designed system will provide a comfortable indoor environment year round when properly maintained.
This mechanical system’s design is primarily an attempt to take control of the environmental conditions inside the space you work.An HVAC system is designed to control the environment in which it works. It achieves this by controlling the temperature of a room through heating and cooling.
Types of HVAC Systems
We can handle complex, multi-layered designs for comprehensive heating and cooling projects. We analyze our clients’ needs and provide mechanical system design services that focus on the functionality and efficiency of HVAC systems. All of our designs are held to IECC and ASHRAE compliance standards. From load calculation to full mechanical plans We ensures that building systems to work together and maintain functionality and operate with the highest levels of energy efficiency.
- Split and Window AC - In a window AC, fans blow air through the coils. This improves how they separate the heat and cold. Heat gets lost to the outside air while introducing cold is into the room. Split ACs are used in larger application areas than window ACs. The split AC focuses on splitting the cold from the hot side of the system. The cold side has the cold coil and the expansion valve. This is usually placed inside a furnace or any other form of air handler. The handler blows air over the coil and the cooled air is distributed to various rooms in the building through the air ducts.
- Packaged Heating & Air Conditioning System - These units provide an all-in-one benefit in that they have both heating and cooling equipment in a single package. Users can place them in mechanical rooms, on the rooftop or at a grade close to the conditioning space.Unlike in split systems where the cold and hot units are separate, the package AC has all the components in one unit. These elements have a centrifugal fan or blower that helps distribute the air throughout the elements of the structure.
- Central AC System - Most of the air conditioners in residential buildings are in the form of split systems – only bigger. They have a cooling fan, a condenser coil and a compressor housed in a separate condensing unit. The evaporator coil is usually inside an air handler (indoor) unit normally installed on the furnace. When the furnace is electric, a blower is included in the system.
