Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
The main task of technical committees is to prepare International Standards. Draft International Standards adopted
by the technical committees are circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 7547 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 3,
Piping and machinery.
This second edition cancels and replaces the first edition (ISO 7547:1985), which has been technically revised.
Annexes A and B of this International Standard are for information only.

Ships and marine technology — Air-conditioning and ventilation of
accommodation spaces — Design conditions and basis of
calculations
1 Scope
This International Standard specifies design conditions and methods of calculation for air-conditioning and
ventilation of accommodation spaces and the radio cabin on board seagoing merchant ships for all conditions
except those encountered in extremely cold or hot climates (i.e. with lower or higher conditions than those stated
in 4.2 and 4.3).
Annex A provides guidance and details of good practice in the design of ventilation and air-conditioning systems in
ships.
Annex B gives the thermal conductivities of commonly used construction materials.
Users of this International Standard should note that, while observing the requirements of this International
Standard, they should at the same time ensure compliance with statutory requirements, rules and regulations as
may be applicable to the individual ship concerned.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.

EXAMPLE The bulb of a mercury-in-glass thermometer is an example of a dry temperature-sensing element.
4 Design conditions
4.1 General
The system shall be designed for the indoor air conditions specified in 4.2 and 4.3 in all accommodation spaces
defined in 3.1 at the stated outdoor air conditions and the outdoor supply airflow, ventilation and air balance given
in 6.2.1, 6.2.2 and 6.5 respectively.
NOTE All temperatures stated are dry bulb temperatures.
4.2 Summer temperatures and humidities
Summer temperatures and humidities are as follows:
a) Outdoor air: + 35 °C and 70 % humidity;
b) Indoor air: + 27 °C and 50 % humidity.
NOTE In practice, the indoor air conditions obtained, especially humidity, can be different from those stated.
4.3 Winter temperatures
Winter temperatures are as follows:
a) Outdoor air: − 20 °C;
b) Indoor air: + 22 °C.
NOTE This International Standard does not specify requirements for humidification in winter.
4.4 Outdoor air
The minimum quantity of outdoor air shall be not less than 40 % of the total air supplied to the spaces concerned.
