CONDENSATE
The liquid formed by condensation of a vapor. In steam heating, water condensed from steam
CONDENSATE POLISHER
A device used to clean the returning condensate to the boiler feedwater system.
CONDENSATE PUMP
Device to remove water condensate that collects beneath an evaporator.
CONDENSATION
Process of changing a vapor into liquid by extracting heat. Condensation of steam or water vapor is effected in either steam condensers or dehumidifying coils, and
CONDENSE
Action of changing a gas or vapor to a liquid.
CONDENSER
An apparatus used to transfer heat from a hot gas, simultaneously reducing that gas to a liquid.
CONDENSER TUBE
The heat transfer surface in a condenser.
CONDENSER
WATER SYSTEM
A re
circulating cooling water used as a heat transfer fluid for the condensation of a gas.
CONDENSING TEMPERATURE
The temperature at which the condensing gas is returned to a liquid at the same pressure.
CONDENSING 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
CONDENSING UNIT SERVICE VALVES
Shutoff valves mounted on condensing unit to enable service technicians to install and/or service unit.
CONDENSING UNIT, REFRIGERANT
An assembly of refrigerating components designed to compress and liquefy a specific refrigerant, consisting of one or more refrigerant
CONDUCTANCE, ELECTRICAL
The reciprocal (opposite) of resistance and is the current carrying ability of any wire or electrical component. Resistance is the ability to oppose the
CONDUCTANCE, SURFACE FILM
Time rate of heat flow per unit area under steady conditions between a surface and a fluid for unit temperature difference between the surface and
CONDUCTION
Transfer of heat by direct contact.
CONDUCTIVITY (ELECTRICAL)
The ability of a liquid to conduct an electrical current and indicating the presence of cations and anions. Conductivity is usually expressed in
CONDUCTIVITY (THERMAL)
The time rate of heat flow through unit thickness of an infinite slab of homogeneous material in a direction perpendicular to the surface, induced by unit
CONDUCTIVITY METER
An electric instrument used to measure the conductivity of water to determine its content of dissolved solids.
CONDUCTIVITY, THERMAL
The time rate of heat flow through unit area and unit thickness of a homogeneous material under steady conditions when a unit temperature gradient is
CONDUCTOR
Substance or body capable of transmitting electricity or heat.
CONDUIT
A round cross
CONGEALER
Also known as freezer.
CONGRUENT PHOSPHATE CONTROL
Similar as a coordinated phosphate control but more restrictive where the equilibrium is based on maintaining a ratio of 2.6 Na/1.0 PO4, instead
