The effectiveness of ventilative cooling has been investigated by many researchers and has been documented in many post occupancy assessments reports. [ 7 ] [ 8 ] [ 9 ] The system cooling effectiveness (natural or mechanical ventilation) depends on the air flow rate that can be established, the thermal capacity of the construction and the heat ...
The house opens onto a central atrium with an impluvium (open to the sky); the evaporative cooling of the water causes a cross-draft from atrium to garden. Primitive ventilation systems were found at the Pločnik archeological site (belonging to the Vinča culture ) in Serbia and were built into early copper smelting furnaces.
Bunnings Limited was bought out by Wesfarmers in 1994 for $600 million. [10] In late-1995, the 'Red Hammer' symbol was introduced and is still in use today. In June 1996, the company's trademark slogan "Lowest Prices Are Just The Beginning" was introduced. In February 2020, the company discontinued the use of the slogan in Australia.
Rooftop HVAC unit with view of fresh-air intake vent Ventilation duct with outlet diffuser vent. These are installed throughout a building to move air in or out of rooms. In the middle is a damper to open and close the vent to allow more or less air to enter the space. The control circuit in a household HVAC installation.
Air conditioning, often abbreviated as A/C (US) or air con (UK), [1] is the process of removing heat from an enclosed space to achieve a more comfortable interior temperature and in some cases also controlling the humidity of internal air.
Usually, a register is placed near a window or door, which is where the greatest heat/cooling loss occurs. [4] [5] In contrast, returns (grilled ducts which suck air back into the HVAC system for heating or cooling) are usually placed in the wall or ceiling nearest the center of the building. Generally, in rooms where it is critical to maintain ...
Benefits of evaporative cooling chambers for many rural communities in these regions include reduced post-harvest loss, less time spent traveling to the market, monetary savings, and increased availability of vegetables for consumption. [11] [12] Evaporative cooling is commonly used in cryogenic applications.
In 1909, KDK of Japan pioneered the invention of mass-produced electric fans for home use. In the 1920s, industrial advances allowed steel fans to be mass-produced in different shapes, bringing fan prices down and allowing more homeowners to afford them. In the 1930s, the first art deco fan (the "Silver Swan") was designed by Emerson. [11]
