Carrier Air Conditioning - Standardised heat recovery unit launched by Carrier
The new Carrier Airosmart heat recovery
unit is a standardized air handling system with significant
energy-saving characteristics. By making heat recovery standard
at even the smallest size of unit, Carrier is meeting a new
market demand driven by legislative changes and the requirement
for energy savings.
For airflows up to 1.3 m3/s a counterflow plate heat exchanger
is used resulting in energy efficiency values up to 90%. For air
flows of 1.7 m3/s and above a heat recovery wheel is used as
standard. A sorption rotor is available as an option to allow
the recovery of both temperature and moisture, increasing
efficiency still further.
The Carrier Airosmart can also be supplied with a complete
bypass circuit enabling free cooling using outside air resulting
in a significant saving in energy consumption, as seen on the
latest Carrier chiller systems that use this technology.
The Airosmart is a ‘plug and play’ system, and is simple to
install. It operates with controllable brushless DC or ‘EC’
motors which use less energy, especially at lower speeds, than
the more commonly used asynchronous motors.
“This unit puts sophisticated heat recovery and controls
technology in a standard ‘off the shelf’ unit that is economic
to produce and sell,” is how Carrier’s air handling unit
director Tony Millard sums up the latest example of innovation
from the market leader in integrated ac systems.
The Carrier Airosmart is available with an air flow range from
0.2 to 4.2 m3/s. It offers integral automatic frost protection.
Options include heating or cooling coils delivered installed
within the same unit structure.
The use of double-skin insulated panels further contributes to
the energy-saving character of the Airosmart. The casing
complies with thermal transmission class T2 and has a cold
bridge factor of TB1 in accordance with EN 1886.
This unit can also be seen as part of the growing trend for
integrated systems. It has a particularly small footprint and
integrates perfectly within a Carrier Aquasmart controlled
hydronic air conditioning system or with standard building
management control systems.
Carrier Corporation, headquartered in Farmington, Connecticut,
USA, is the world’s largest provider of heating, air
conditioning and refrigeration solutions with operations in 172
countries. It is part of United Technologies Corp, (NYSE:UTX) is
