Specifies the testing Standards for room airconditioners. This Standard is technically equivalent to and reproduced from ISO 5151:1994. <\/p>\n
Scope<\/b><\/p>\n
1.1 This International Standard specifies the standard conditions on which the ratings of single-package and split-system non-ducted air conditioners employing air- and water-cooled condensers and heat pumps employing air-cooled condensers are based, and the test methods to be applied for determination of the various ratings. This International Standard is limited to systems utilizing a single refrigeration circuit and having one evaporator and one condenser. <\/p>\n
NOTE 1 For the purposes of this International Standard, the term "equipment" will be used to mean "non-ducted air conditioners and\/or non-ducted heat pumps". <\/p>\n
1.2 This International Standard also specifies the test conditions and the corresponding test procedures for determining various performance characteristics of these non-ducted air conditioners and heat pumps. <\/p>\n
1.3 It does not apply to the testing and rating of:
a) water-source heat pumps;
b) multiple split-system1)air conditioners and heat pumps;
c) units designed for use with additional ducting; or
d) mobile (windowless) units having a condenser exhaust duct. <\/p>\n
1.4 Clause 4 of this International Standard covers the rating and testing conditions for non-ducted air conditioners and heal pumps when used for cooling. <\/p>\n
1.5 Clause 5 of this International Standard covers the rating and testing conditions for non-ducted air conditioners and heat pumps when used for heating. The means for heating may be the heat pump refrigeration cycle or electrical resistance. <\/p>\n
1.6 Annex A establishes testing procedures. Annex B describes the test facilities for the calorimeter method. Annex C provides formulae for the calculation of heating and cooling capacities. Annex D describes instruments which can be used in making measurements, and annex E describes methods for measuring air-flow. Annex F describes the outdoor air-enthalpy test method. Annex G gives a list of symbols used in the annexes.<\/p>\n","protected":false},"excerpt":{"rendered":"
