Outdoor Heating
Outdoor heating is space heating that allows people to stay in substantially unenclosed spaces that would otherwise be too cold for comfort. To this end, various outdoor heating appliances are available, including gas patio heaters, quartz or ceramic electric lamps, and wood burning chimenea and fire pits. In an outdoor environment, convection would quickly carry away heat in the form of hot air, so all these methods emit various amounts of their total output as radiant heat Thermal radiation is electromagnetic radiation emitted by the thermal motion of particles in matter. All matter with a temperature greater than absolute zero emits thermal radiation. The emission of energy arises from a combination of electro .... Radiant heat is emitted from the appliance, and is absorbed by objects and people, raising their temperature. References {{energy-stub Heating ...

Space Heating
A heating system is a mechanism designed to regulate and maintain a desired temperature within a space by utilizing thermal energy. It is a fundamental component of Heating, Ventilation, and Air Conditioning (HVAC) systems, providing warmth to residential, commercial, and industrial buildings. Heating systems are classified into two main types: central heating and distributed heating. Central heating systems generate heat (electrically or by burning gas/coal) in a single location and distribute the heat through ducts pipes or radiators. Distributed heating systems involve localized heat sources, such as space heaters or electric radiators. Distributed heating systems do not rely on the use of ducts, pipes or radiators. These systems are critical to ensure indoor comfort especially in colder regions. Types and uses Central heating systems: These systems produce heat in one central location and distribute it throughout the building. This category includes furnaces, boilers, and heat ...

Patio Heater
A patio heater, also called a mushroom heater or umbrella heater, is a radiant heating appliance for generating thermal radiation for outdoor use. Types of heater A burner on top of a pole, it burns natural gas, liquefied petroleum gas (LPG), propane or butane, and directs the flames against a perforated metal screen. Heat is radiated from the surface of the screen in a circular pattern around the appliance. A reflector a top the burner reflects heat that would be otherwise lost upwards. This is because the reflecting hood is usually silvered which makes it a poor absorber of heat but excellent at reflecting infrared radiation back. This reduces the amount of heat lost by conduction as silvered surfaces will not absorb infrared light. The chimenea is an alternative to the patio heater for home use, which burns wood instead of gas. Some newer types of patio heaters are Electric heating#Radiative heaters, electrically powered radiative heaters that emit infrared energy onto nearby s ...

Chimenea
A chimenea (UK English) or chiminea (US English) ( ; from Spanish , in turn derived from French , "chimney") is a freestanding front-loading fireplace or oven with a bulbous body and usually a vertical smoke vent or chimney. History Historically chimeneas have been made out of fired clay and used for heating and cooking. These traditional designs can be traced to Spain and its influence on Mexico. The first use of a traditionally designed chimenea appears around 400 years ago. The chimenea was once a daily life necessity that served a domestic purpose. The chimenea of the past was used indoors for heating and cooking, usually by an open window or in the center of the hut or home with an opening in the roof to allow smoke to escape. With the advent of the modern home, chimeneas are now used outdoors mainly for entertainment in a backyard setting. More modern clay chimeneas have clay that has been heavily grogged to better handle the thermal stresses that often fracture tradi ...

Convection
Convection is single or Multiphase flow, multiphase fluid flow that occurs Spontaneous process, spontaneously through the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be assumed. Convection may also take place in soft solids or mixtures where particles can flow. Convective flow may be Transient state, transient (such as when a Multiphasic liquid, multiphase mixture of oil and water separates) or steady state (see convection cell). The convection may be due to Gravity, gravitational, Electromagnetism, electromagnetic or Fictitious force, fictitious body forces. Convection (heat transfer), Heat transfer by natural convection plays a role in the structure of Earth's atmosphere, its oceans, and its Earth's mantle, mantle. Discrete convective cells in the atmosphere can be identified by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiant Heating
Radiant heating and cooling is a category of HVAC technologies that exchange heat by both convection and radiation with the environments they are designed to heat or cool. There are many subcategories of radiant heating and cooling, including: "radiant ceiling panels",ISO. (2012). ''ISO 11855:2012—Building environment design-Design, dimensioning, installation and control of embedded radiant heating and cooling systems''. International Organization for Standardization. "embedded surface systems", "thermally active building systems", and infrared heaters. According to some definitions, a technology is only included in this category if radiation comprises more than 50% of its heat exchange with the environment; therefore technologies such as radiators and chilled beams (which may also involve radiation heat transfer) are usually not considered radiant heating or cooling. Within this category, it is practical to distinguish between high temperature radiant heating (devices with em ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
