Heating & Ventilation Heating & ventilation an important aspects of the design of structures such as single-family homes; small and large commercial buildings; vehicles and marine environments. The systems are analyzed, designed, and specified by mechanical contractors or professional engineers who specialize in building services engineering. Natural ventilation happens naturally through doors and windows in a home, replenishing oxygen levels and removing odors and excess moisture. Mechanical ventilation uses an air handling unit to transport air both in and out. Cooling Cooling involves speeding up the natural process of thermal energy moving from high areas to low areas. It happens through conduction, radiation, and convection. Ventilation enhances these processes. The faster heat is removed from products, the cooler they will be and the less energy they will use to maintain their temperature. The systems that keep your house or office warm and cozy in the winter and cool and fresh in the summer are called heating, ventilation, and air conditioning (HVAC). They also remove humidity to comfortable levels and clean indoor air to help you stay healthy. This is why it’s important to have the right system for your needs and install it correctly. It will make a huge difference in your comfort and energy bills. Petro Home Services is a professional HVAC company that can provide all your heating and cooling needs.

Ventilation Ventilation is the movement of outdoor air into a space and then through that space to remove, dilute or replace indoor pollutants. It also moves heat and moisture and may control temperature and humidity. It is a key factor in the overall health and comfort of building occupants (Etheridge & Sandberg, 1996; Awbi, 2003). In homes, ventilation moves fresh air into living spaces to help reduce moisture build-up and air quality issues such as radon. It is a key factor in energy efficiency and the ASHRAE standard 62.2 specifies that an appropriate amount of ventilation must be provided. The human respiratory system relies on natural ventilation to provide the required amount of fresh air. An impulse from the brainstem is generated within the medulla oblongata and travels distally through cervical nerves three, four, and five until it arrives at the phrenic nerve just above the clavicle, which initiates diaphragm movement and ventilates the lungs. The same principles are used in mechanical ventilation systems. Heating Heat is emitted by hot surfaces in your home — including ceilings, walls, and furnishings. It can also radiate from your body to the cooler objects around you. Ventilation enhances the processes of convection, radiation, and perspiration. As air rises, it carries heat with it, and cooler air moves in to take its place. When ventilation removes the heat from the surface of your home’s furnishings and ceiling, it helps reduce heating bills. It also makes the room feel more comfortable. Indoor Air Quality Since people spend most of their lives indoors, and because outdoor air is generally cleaner than indoor air, there is a great need to improve the quality of indoor air. This OSH Answers page focuses on four main ways to do so: source control, ventilation, filtration, and disinfection. Common sources of air pollutants include cigarette and other types of smoke, cooking fumes, paints, cleaners and pressed wood products. Some pollutants may also come from outside through poorly sealed windows, building, and construction materials, and drifting sand and dust. Many illnesses and health effects are linked to poor indoor air quality, such as some respiratory diseases, heart disease, and cancer. Some of these effects appear soon after exposure, while others take longer to develop and may only show up over long or repeated periods of exposure. Indoor air quality issues can be addressed on a whole building or room-by-room basis, depending on the problem and available resources. For example, reducing indoor humidity by using a dehumidifier can help prevent mold.
