A condensing boiler Hot water central heating unit, using wood as fuel. A central heating system provides warmth to a number of spaces within a building from one main source of heat. A central heating system has a furnace that converts fuel or electricity to heat.
The schematic is a line diagram, not necessarily to scale, that describes interconnection of components in a system. The main features of a schematic drawing show: A two dimensional layout with divisions that show distribution of the system between building levels, or an isometric-style layout that shows distribution of systems across ...
Underfloor air distribution is frequently used in office buildings, particularly highly-reconfigurable and open plan offices where raised floors are desirable for cable management. UFAD is also common in command centers , IT data centers and Server rooms that have large cooling loads from electronic equipment and requirements for routing power ...
Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.
Hypocaust under the floor in a Roman villa in Vieux-la-Romaine, near Caen, France. A hypocaust (Latin: hypocaustum) is a system of central heating in a building that produces and circulates hot air below the floor of a room, and may also warm the walls with a series of pipes through which the hot air passes.
A diagram of a "paint-can"-type heating mantle. (A)=beaker outside the mantle; (B)=beaker within the basket of the mantle; (C)=the main body of the heating mantle; and (D)=the power cord for connecting the mantle to a source of AC electricity (usually a
Heaters are appliances whose purpose is to generate heat (i.e. warmth) for the building. This can be done via central heating. Such a system contains a boiler, furnace, or heat pump to heat water, steam, or air in a central location such as a furnace room in a home, or a mechanical room in a large building.
Because the net variation in state properties during a thermodynamic cycle is zero, it forms a closed loop on a P-V diagram. A P-V diagram's abscissa, Y axis, shows pressure (P) and ordinate, X axis, shows volume (V). The area enclosed by the loop is the net work done by the processes, i.e. the cycle:
