SCOPE

1.1
This Standard specifies the methods for determining the uniform energy factor for electric storage tank water heaters and heat pump water heaters.

1.2
This Standard establishes minimum energy efficiency levels for electric storage tank water heaters and heat pump water heaters.

1.3
This Standard applies to
a) electric storage tank water heaters
i) with volumes of 7.6 to 454 L (2 to 120 US gal);
ii) having electric heater elements with power inputs ≤ 12 kW; and
iii) designed to heat and store water at a thermostatically controlled temperature equal to or less than 82 ºC (180ºF); and
b) heat pump water heaters that have
i) a maximum current rating of ≤ 24 A; (including the compressor and all  auxiliary equipment such as fans, pumps, controls, and, if on the same circuit, any resistive elements
ii) A maximum wattage rating ≤ 15kW
iii) a single-phase maximum voltage of ≤ 250 V; and
iv) with volumes of 7.6 to 454 L (2 to 120 US gal);
     v) rated storage volume ≤ 454 L (120 US gal);   

1.4
This Standard does not apply to high-temperature water heaters.

1.5
The tests contained in this Standard are not intended to represent actual efficiencies realized in the field. Instead, these tests provide a standardized method of comparing performance. 

1.6
This Standard is written in SI units. The values given in parentheses are for information only. The SI values have been calculated from the US Customary Units measurements found in the US Department of Energy publication 10 CFR, Part 430, appendix E, subpart

Scope

1.1 Inclusions

Intended to be used for an industrial clean-water pumping system with the following characteristics:

Intended to be used for an industrial clean-water pumping system with the following characteristics:

a) Any application of electrically driven single and multi-stage rotodynamic pumps.

b) Pumping system with a flow range between 20 m3/hr to 36,000 m3/hr.

c) All liquids with viscosity up to 25 cSt provided that ANSI/HI 9.6.7 is used to correct the performance to 1 cSt. 

1.2 Exclusions

Not intended for use for the following a pumping system:

a) Application of positive displacement pumps.  Defined as a category of pumps where a set volume of liquid is trapped in a chamber and conveyed from the suction side of the pump to the discharge side of the pump through displacement of liquid by a solid component such as a piston, plunger, gear tooth, vane, screw, diaphragm, etc.

b) Pumping system applications handling shear-sensitive liquids.

1 Scope

1.1 General

1.1.1

These procedures apply to unitary air conditioners and heat pumps that are

a) factory-made;
b) air-source and air-sink;
c) single-split systems with matching assemblies or single package for use in ducted and/or non-ducted distribution systems;

d) intended for space-heating and/or air-conditioning applications in buildings;
e) electrically driven, mechanical, vapour-compression-type systems; and
f) rated below 65,000 Btu/h (19.0 kW) heating or cooling at standard rating conditions, in accordance with Clause 5.2.

Note: This includes space-constrained single-package or split-system and small-ducthigh-velocity central air conditioners and heat pumps matching assemblies of the type classified in Clause 1.2 and intended for air-conditioning and space-heating applications in buildings.

1.1.2

These procedures do not apply to the following:

a) water to air and/or water units; and
b) heat recovery.

1.2 Unitary equipment

Unitary equipment within the scope of these procedures is outlined in Table 1.

1.3 Terminology

In these procedures, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with these procedures; “should” is used to express a recommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of these procedures; and “can” is used to express possibility or capability.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.4 Units of measurement

The values given in IP (inch-pound) units are normative. Metric values given in parentheses are for information only.
