Refrigerant Emission
Control
Conservation and emission
reduction can be accomplished by
following recommended Trane
operation, maintenance and service
procedures, with specific attention to
the following:
1 Refrigerant used in any type of air
conditioning or refrigerating
equipment should be recovered for
reuse, recovered and/or recycled
for reuse, or reprocessed
(reclaimed). Never release
refrigerant into the atmosphere.
2 Always determine possible recycle
or reclaim requirements of the
recovered refrigerant before
beginning recovery by any
method.
3 Use approved containment vessels
and safety standards. Comply with
all applicable transportation
standards when shipping
refrigerant containers.
4 To minimize emissions while
recovering refrigerant, use
recycling equipment. Always
attempt to use methods which will
pull the lowest possible vacuum
while recovering and condensing
refrigerant into containment.
5 Refrigeration-system cleanup
methods that use filters and dryers
are preferred. Do not use solvents
that have ozone depletion factors.
Properly dispose of used materials.
6 Take extra care to properly
maintain all service equipment that
directly supports refrigeration
service work, such as gauges,
hoses, vacuum pumps and
recycling equipment.
7 Stay aware of unit enhancements,
conversion refrigerants,
compatible parts and
manufacturer's recommendations
which will reduce refrigerant
emissions and increase equipment
operating efficiencies. Follow
manufacturer's specific guidelines
for conversion of existing systems.
8 In order to assist in reducing
power-generation emissions,
always attempt to improve
equipment performance with
improved maintenance and
operations that will help conserve
energy resources.
All the air-cooled RTAD chillers are
given a complete functional test at the
factory covering sensors, wiring,
electrical components,
microprocessor function,
communication capability, expansion
valve performance and fans. Where
applicable, each unit is factory preset
to the customer's design conditions,
including leaving water temperature
setpoint, current limit, and reset
temperature setpoint.
Note: Free-Cooling units are freeze-
protected with 30% ethylene glycol
in the cooling loop circuit which is
the most convenient percentage to
protect the unit against freeze-up.
Protection coverage with 30%
ethylene glycol:
- freezing point without burst effect =
-13°C
- freezing point with burst effect =
- 50°C
It is necessary to regularly check the
percentage of ethylene glycol in the
water circuit (at least every three
months).
