Upright non-flued liquefied petroleum gas heater, 1970s A wall mounted gas heater that runs on either propane or natural gas. A gas heater is a space heater used to heat a room or outdoor area by burning natural gas, liquefied petroleum gas, propane, or butane. Indoor household gas heaters can be broadly categorized in one of two ways: flued or ...
Bake-out, in several areas of technology and fabrication, and in building construction, refers to the process of using high heat temperature (), and possibly vacuum, to remove volatile compounds from materials and objects before placing them into situations where the slow release of the same volatile compounds would contaminate the contents of a container or vessel, spoil a vacuum, or cause ...
Barium iodide is an inorganic compound with the formula BaI 2.The compound exists as an anhydrous and a hydrate (BaI 2 (H 2 O) 2), both of which are white solids.When heated, hydrated barium iodide converts to the anhydrous salt.
HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the ...
The absorption heat pump can be used as a cooler during summer while, during winter, it can be used on heat pump or heat transformer mode according to the available heat source. [6] The performance of the absorption heat pump is indicated by the coefficient of performance (COP). The COP is the ratio of the removed (for refrigeration) or ...
A thermosiphon (or thermosyphon) is a device that employs a method of passive heat exchange based on natural convection, which circulates a fluid without the necessity of a mechanical pump. Thermosiphoning is used for circulation of liquids and volatile gases in heating and cooling applications such as heat pumps, water heaters, boilers and ...
Gas stations are routine stops for most people, but they also present opportunities for criminals to take advantage of those who are unaware. Before you fill up your tank next time, it's important ...
Trends include the integration of smart home technology for better system control through allowing heat schedules, zones, and remote control. The use of renewable energy sources like geothermal heating, solar panels, and biomass. Current trends are toward heating pumps and using renewable energy/low carbon emission energy to power these heaters ...
