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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Introduction
The ISO 19659 series defines terms, thermal comfort, energy efficiency and system installation of
heating, ventilation and air conditioning (HVAC) for rolling stock.
The purpose of this document is to standardize the terms, definitions, symbols and abbreviated terms
used throughout trains systems for the cooling, heating and internal air circulation that are commonly
known as heating, ventilation and air conditioning (HVAC). These can be broken down into multiples of
these functions and as an example, ventilation and air conditioning (VAC), etc.

3.1.2 Position
3.1.2.1
centralized system
system which consists of one set of HVAC unit (3.1.3.1) per car

decentralized system
system which consists of two or more sets of HVAC unit (3.1.3.1) per car
Note 1 to entry: This can also be referred to as “dispersed system”.
3.1.3 Equipment
3.1.3.1
HVAC unit
unit intended for cooling (3.1.1.1) and/or dehumidification (3.1.1.3) and/or heating (3.1.1.4), and/or
ventilation (3.1.1.7)
3.1.3.2
controller unit
unit which operates the HVAC system in a predetermined behaviour while exchanging data with
external devices
