HVAC systems are milestones of building mechanical systems that provide thermal comfort for occupants accompanied with indoor air quality. HVAC systems can be classified into central and local systems according to multiple zones, location, and distributi
Heating and cooling split systems are the most common types of HVAC systems used in residential buildings. They consist of two separate components — one for heating and one for cooling — and use a traditional thermostat to control the temperature for the entire structure. In most buildings with...
These HVAC systems were implemented in one residential-complex which consisted of a three-story block subdivided into 15 apartments with total floor area of 1050 m(2). Year-round dynamic simulations were carried out using Energy Plus based on three different climatic conditions from northern, ...
Sturdy and distinct, rectangular air ducts are often the best option for low-pressure HVAC systems in residential homes. These ducts can be fabricated in-shop or on a truck by contractors with a brake, but are typically considered harder to install than round ductwork. ...
The residential elevator size is usually small. Due to its compact design, it often comes with the capacity to transport only two to three people at a time. Moreover, with drive systems with limited power output, a home lift can serve a maximum of four to five floors. ...
Air duct cleaning clears dust, mold, and other pollutants from heating, ventilation, and air conditioning (HVAC) systems—improving indoor air quality. Tasks: Inspecting and assessing the ductwork for signs of contamination Using high-powered vacuums and brushes to clean ducts ...

HVAC units can be placed on top of the roof to keep them well hidden Makes adding solar panels very convenient Disadvantages: Highly susceptible to leaks as water may often pool on top of them Require ongoing maintenance, which can be expensive to keep up with ...
In this paper, a co-simulation approach was applied to two case studies, a residential and an educational building, to evaluate different control strategies for hybrid ventilation systems in terms of annual energy demand and risk mitigation. The simulations were performed using TRNSYS and CONTAM and...
There are residential heating/cooling systems that include both a heat pump and traditional forced-air HVAC components. In addition to a forced-air furnace, the system features an outdoor heat pump unit (usually an air-source type) that handles the heating and cooling duties during low-demand ...
