Air Conditioners Types and Terms
Types of Industrial Air Conditioners
- produce cooling units used in homes, offices, and commercial and industrial buildings.
- use a refrigerant to cool indoor areas.
- are strong enough to handle large spaces.
-
are mobile, self-contained air conditioners that do not require professional
installation. Computer room air conditioners, which can be wheeled into
any room that requires cooling, continuously exhaust warm, humid air
through a window, ceiling or vent without dripping.
- is a split-air conditioning system that primarily uses
only recirculated air to cool an environment through a system of ducts,
which move the cooler air where needed. Some duct systems can introduce
fresh air into the current.
- consist of
quiet, compact, indoor air distribution units and an efficient outdoor
compressor linked by refrigerant lines. Ductless air conditioner units
are used where ductwork was previously unavailable or unnecessary,
as in the case of smaller environments.
- are designed to cool work areas and other enclosures in hazardous locations
in which specific volatile flammable liquids or flammable gases are
handled or used.
- can cool larger areas and come in two main types:
single-unit and split-systems. Single-units are mounted through a wall
or window with the hot coil on the outside and cool only the area in
which they are situated, while the cool coil of a split-system is inside
a room and all the other components are located outdoors.
- are single-unit,
packaged, three-phase pieces of equipment that are capable of up to
240,000 BTU/h.
- , also referred to as "spot coolers,"
are often used in temporary environments, such as construction or other
industrial sites. Portable air conditioners can be ducted with a variety
of supply and return configurations.
- can range from small, portable air conditioners for
domestic applications to industrial air conditioners for cooling warehouses
or other large facilities. Rental air conditioners are especially useful
in the instance of failure of an existing cooling system.
- , also called "liquid chillers," are
lightweight air conditioners that are used primarily for the cooling
of electronic equipment, such as computers, and do not employ the use
of chemicals or filters.
Industrial Air Conditioner Terms
-
A shell-shaped device that is incorporated into an HVAC (heating, ventilation,
air conditioning) system within the suction line in order to protect the
compressor from liquids.
- Air-conditioning
driven by a compressor.
- Drying air
or gas by holding moisture vapor on a desiccant surface without mixing
with its molecular structure.
- The indoor
unit of an air conditioning system that provides conditioned air into
a space. An air handler consists of a heat exchange coil, filters and
a fan.
-
A unit of measurement of heat or energy. One BTU is the amount of heat
needed to raise or reduce the temperature of one pound of water by one
degree Fahrenheit.
- The maximum amount
of heat energy that can be removed from or added to a medium by an HVAC
system.
- Also referred to
as the "heart" of a refrigerating or a/c system, a compressor
is a pump that uses pressure to move refrigerant through pipes between
an outdoor condensing unit and an indoor evaporating unit.
- The process
of changing air into liquid.
- A substance
suitable for absorbing and adsorbing moisture.
-
The utilization of a central utility system to heat or cool large residential
and industrial areas.
- A device used
to distribute air.
- A device used
for the removal of solid and liquid particles.
- Cooling
with an evaporator that does not have a fan to circulate the air.
- (http://www.heatexchangers.org)
A device capable of transferring heat from one place or medium
to another.
- Mass of
water vapor present per unit volume of air, usually measured as grains/ft3,
lbs/ft3 or grams/ft3.
- The
total pressure at the inlet flange of the compressor.
- The required rate
of heat removal.
-
A device that separates condensate from an air stream.
- A heat
exchanger that lowers the temperature of the inlet air with the help
of the outgoing cold air. In the process, the outgoing air is reheated
by the incoming air.
- The medium
of heat transfer in a refrigeration system that picks up heat by evaporating
at a low temperature and rejects heat by condensing at a high temperature.
- A regenerative
desiccant.
- The
pressure exerted on a liquid and vapor surface.
