"ECONO-PILOT”ENERGY-SAVING SYSTEM FOR WATER PUMPS
We have developed the “Econo-Pilot” energy-saving system for water pumps,
which reduces the power consumption of motors for water supply. In the energy-
saving control field, the conventional method used is that of constant pressure control
of the water supply with inverters. However, as Econo-Pilot employs a method of
variable water pressure control corresponding to flow volume, the system can raise
the energy-saving ratio up to 90 percent.
This paper describes the principles of the system and its basic functions, along with a
case study of some practical applications.
INTRODUCTION
With the background of fulfilling public commitments for the prevention of
global warning, many countries have consolidated related laws and regulations aiming
to reduce energy consumption. Energy conservation has become one of the important
issues for companies and organizations accredited with the ISO 14000 series
standards certification because they are required to achieve yearly targets for
improvements, which have, in a sense, the same implications as laws. In a prolonged
recession, investments in energy-saving activities directly linked with cost reduction
have attracted increasing attention.
However, large-scale renewal investments which entail enormous costs cannot be
implemented easily. Consequently, there have been increasing needs for energy
conservation activities which bring about substantial cost reduction effects but can be
conducted inexpensively with ease and minimum risks, while at the same time
utilizing existing facilities.
Figure 1 is a graphical indication of the energy consumption ratios of office
buildings, which is based on research conducted by the Building-Energy Manager's
Association of Japan. As indicated in the graph, air conditioning-related items account
for half of the total consumption. This means that air conditioning must be the main
target for energy conservation.
Figure 1 Energy Consumption of Office Buildings by Usage
Among air conditioning-related technologies, we have focused on the control of
air conditioning pumps and have developed a new energy-saving control system

called "Econo-Pilot" which meets the requirements for implementations mentioned
earlier system.
The Econo-Pilot adopts a new control mechanism contrived by three enterprises-
Yokogawa Electric Corporation, Asahi Kogyosha Co, Ltd., and The First Energy
Service Company, Limited-and was commercialized by Yokogawa after the
development and demonstration phases, through joint research with the New Energy
and Industrial Technical Development Organization (NEDO).
OVERVIEW OF AN AIR CONDITIONING SYSTEM
Figure 2 shows an overview of an air conditioning system. Broadly speaking,
energy is consumed by heat sources, water pumps, and ventilators.
FIgure 2 Overview of an Air Conditioning System
A heat source generates cold/hot water through gas combustion in the case of
applying a gas-based cold/hot water generator, the cold/hot water is then conveyed to
air conditioners by water pumps. Inside air conditioner, the cold/hot water is flowing
through heat exchange equipment where air is warned up or cooled when passing
through the heat exchange equipment via ventilators- and then the warned/cooled air
is blown to an area through ducts.
Water pumps are mainly classified into primary pumps, secondary pumps, and
cooling pumps, but their power consumption is almost the same. Among them, we
have focused on secondary water pumps whose flow volume varies significantly
according to demand.
