Periodic Maintenance
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 and/or
recycled for reuse, 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
1000
2000
standards. Comply with all applicable transportation
37
37
standards when shipping refrigerant containers.
40
30
4.
To minimize emissions while recovering refrigerant,
42
32
42
use recycling equipment. Always attempt to use
34
45
38
methods that will pull the lowest possible vacuum
48
40
while recovering and condensing refrigerant into
42
34
containment.
45
38
48
40
5.
Refrigerant-system cleanup methods that use filters
48
39
and dryers are preferred. Do not use solvents that
53
47
have ozone depletion factors. Properly dispose of
56
50
used materials.
49
40
53
47
6.
Take extra care to properly maintain all service
56
50
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 that will reduce refrigerant
emissions and increase equipment operating
efficiencies. Follow the manufacturer's specific
1000
2000
guidelines for conversion of existing system.

In order to assist in reducing power-generation
53
62
56
emissions, always attempt to improve equipment
58
51
performances with improved maintenance and
62
56
operations that will help conserve energy resources.
