Heat is absorbed from the inside of a refrigerated area through the evaporator coil. It is then delivered to the condenser where it is dissipated…
1. Liquid refrigerant tends to vaporize as pressure imposed upon it is reduced. (It is already known that water boils at a lower temperature at…
Different liquids boil at different temperatures. Some need a great deal of heat to reach their boiling point to vaporize while others require very little.…
It is possible to use the boiler of a hydronic heating system to supply heat for such purposes as snow melting, a swimming pool, domestic…
A hydronic hot-water heating system circulates hot water to every room through baseboard panels. “Hydronic” is another term for forced hot-water heating. The hot water…
Radiant-panel heating is the method of heating a room by raising the temperature of one or more of its interior surfaces (floor, walls, or ceiling)…
In the forced-circulation type of hot-water system, a pump is used to force the water through the pipingThus, the flow is entirely independent of the…
Hot-water heating systems transmit only sensible heat to radiators, as distinguished from steam systems that work principally by the latent heat of evaporation. The result…
Two-pipe medium- and high-pressure systems (with ranges of 25 to 125 psi) are used for space heating and for steam-process equipment such as water heaters,…
The vacuum-air-line system is a variation of the one-pipe steam-heating system. Radiator air vents arereplaced with air valves, the outlets of which are connected to…
