FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION

This document deals with the performance test methods for binary power generation systems.

Binary power generation systems are capable of generating electric power even with a relatively

low temperature heat source, such as factory waste heat as well as renewable energy, such as

hot spring water, geothermal heat, solar heat, etc..

The system utilizes the heat of said heat source by transferring it to a working fluid via a heat

transport medium, instead of directly heating working fluid. Hence, it is called “binary system.”

By standardizing the performance measuring method of binary power generation systems,

energy conservation performance can be assessed legitimately, and it will also be reflected in

energy saving measures based on actual use. Increase of suppliers motivation for realizing high

energy saving performance is expected, and energy saving products will be promoted around

the world.

In addition, the world demand for binary power generation systems is also rising, and it is

expected to grow rapidly in the future.

BINARY POWER GENERATION SYSTEMS WITH CAPACITY
LESS THAN 100 KW – PERFORMANCE TEST METHODS
1 Scope

This document specifies the performance test methods for binary power generation systems.

It defines the normalized test conditions and estimates the power generation efficiency of binary

power generation systems.

It specifies the binary power generation systems having heating medium of non-pressurized hot

water, with a maximum temperature less than 100 °C created by renewable energy or wasted

heat in the industrial field and cold water as cooling medium.

It is applied to binary power generation systems with electric power generation capacity of less

than 100 kW.

This document specifies performance testing, the standard conditions and the test methods for

determining the electric power output and power generation efficiency of binary power

generation systems.

It includes heating conditions (temperature, flow rate) and cooling conditions (temperature, flow

rate).

The requirements of testing and rating contained in this document are based on the use of

matched assemblies.

This document does not include binary power generation systems more than 100 kW in electric

power generation capacity.

The subject heating medium here is non-pressurized hot water with a temperature of less than

100 °C.
