|
| A mixture of portland cement, fine aggregate, coarse aggregate, admixtures, air, and water.
|
| The application of supplemental heat to a structure during a welding or cutting operation.
|
| The point at which the line of action of several forces meet.
|
| A procre by which private property is acquired for public use by the legal process of eminent domain.
|
| A pump that removes water or condensation from an air-cooling unit.
|
| A product obtained by cooling vapors of a substance being distilled.
|
| A drain pipe to carry off water condensed from the atmosphere.
|
| The process of changing from a gaseous to a liquid state, especially as applied to water; liquid drops which form when a vapor is chilled below its boiling point; water droplets that deposit on surfaces whose temperature is below the dew point.
|
| Action of changing a gas or vapor to a liquid.
|
| Comb-like device, metal or plastic, used to straighten the metal fins on condensers or evaporators.
|
| Forced air device used to move air through air- cooled condenser.
|
| Heat exchanger which transfers heat to surrounding air.
|
| Heat exchanger designed to transfer heat from hot gaseous refrigerant to water.
|
| A heat exchanger in a refrigeration cycle used to discharge heat to the outside; commonly used types are water cooled, air cooled, and evaporative; condenser water is normally circulated through a cooling tower through which heat is distributed to the atmosphere.
|
| Pressure inside a condenser at which refrigerant vapor gives up its latent heat of vaporization and becomes a liquid; this varies with the temperature.
|
| Temperature inside a condenser at which refrigerant vapor gives up its latent heat of vaporization and becomes a liquid; this varies with the pressure.
|
| Shutoff valves mounted on condensing unit to enable service technicians to install or service unit.
|
| Part of a refrigerating mechanism which pumps vaporized refrigerant from the evaporator, compresses it, liquefies it in the condenser and returns it to the refrigerant control.
|
| Air that has been heated, cooled, humidified, or dehumidified to maintain an interior space within the comfort zone; also called Tempered Air.
|
| In swimming pools, water treated with cyanuric acid or chlorinated isocyanurate to prevent chlorine from dissipating in sunlight.
|
| Individual ownership of a unit in a multi-unit development, as dwellings, offices, storage, or manufacturing spaces; also includes ownership of an interest, in common with other owners, of common areas and facilities that serve the structure.
|
| 1. The property of a material to conduct electric current. 2. A property of a material to conduct heat; a property of a slab of material equal to the quantity of heat, in BTU. per hour, that flows through 1 square foot of the slab, when a 1 degree F. temperature difference is maintained between the two sides.
|
| Heat transfer from one particle to another in direct contact with it.
|
| Flooring material specifically designed to prevent electrostatic buildup and sparking.
|
| A tile mortar to which specific electrical conductivity is imparted through the use of conductive additives.
|
| A type of tile that prevents electrostatic buildup and sparking, that is made from specific conductive materials.
|
| Tile made from special body compositions or by methods that result in specific properties of electrical conductivity while retaining other normal physical properties of ceramic tile.
