Definitions 186 The following definitions apply in this Division. CSA C656-05 means the CSA standard CAN/CSA-C656-05 entitled Performance Standard for Split-System and Single-Package Central Air Conditioners and Heat Pumps . ( CSA C656-05 ) CSA C656-14 means the CSA standard CAN/CSA-C656-14 entitled Performance Standard for Split-System and Single-Package Central Air Conditioners and Heat Pumps . ( CSA C656-14 ) CSA C746-06 means the CSA standard CAN/CSA-C746-06 entitled Performance Standard for Rating Large and Single Packaged Vertical Air Conditioners and Heat Pumps . ( CSA C746-06 ) CSA C13256-1 means the CSA standard CAN/CSA-C13256-1-01 entitled Water-Source Heat Pumps — Testing and Rating for Performance — Part 1: Water-to-Air and Brine-to-Air Heat Pumps . ( CSA C13256-1 ) small-duct and high-velocity means, with respect to a split system central heat pump or a single package central heat pump, one that has an indoor blower and coil combination that (a) produces at least 300 Pa (1.2 inches of water) external static pressure when operated at an air volume rate of 104 to 165 L/s (220 to 350 cubic feet/minute) per nominal ton of cooling; and (b) uses room outlets that produce velocities greater than 5 m/s (1,000 feet/minute) and that each have an area less than 39 cm 2 (6 square inches). ( à grand débit et à petits conduits ) space-constrained , with respect to a single package central heat pump or a split system central heat pump, means one that (a) has a cooling capacity that is less than or equal to 8.79 kW (30,000 Btu/h); and (b) has an outdoor or indoor unit (i) that has an overall displacement that is — or two or more overall exterior dimensions that are — substantially smaller than those of other units of a similar cooling capacity that are usually installed in single-family homes, and (ii) with respect to which an increase in the overall displacement or two or more overall exterior dimensions would result in a considerable increase in the usual cost of installation or in a significant loss in the utility of the product to the consumer. ( à espace restreint ) 10 C.F.R. Appendix F1 means Appendix F1 to Subpart F, Part 431 of Title 10 to the United States Code of Federal Regulations , entitled Uniform Test Method for the Measurement of Energy Consumption of Air-Cooled, Three-Phase, Small Commercial Package Air Conditioning and Heating Equipment With a Cooling Capacity of Less Than 65,000 Btu/h and Air-Cooled, Three-Phase, Variable Refrigerant Flow Multi-Split Air Conditioners and Heat Pumps With a Cooling Capacity of Less Than 65,000 Btu/h , as amended from time to time. ( appendice F1 10 C.F.R. ) 10 C.F.R.
