Description / Abstract:
This guide discusses the ventilation and thermal management of
stationary battery systems as applied to the following:
— Vented (flooded) lead-acid (VLA)
— Valve-regulated lead-acid (VRLA)
— Nickel-cadmium (NiCd)
For each category, both the technology and the design of the
battery are described in order to facilitate user understanding of
the environmental issues associated with each type of
technology.
The scope of this document includes only stationary batteries
under conditions of expected use. Multiple operating modes are
identified.
The ventilation practices described in this guide represent the
"best practice" based on the information available at the time this
document was developed. The user should evaluate these practices
against their operating experience, operating conditions, number
and size of battery systems, manufacturer's recommendations,
resources, and needs in developing an environment that maximizes
safety and is conducive to optimum operation of the equipment.
These recommendations were developed without consideration of
economics, availability of equipment and personnel, or relative
importance of the application. Design of a ventilation system for a
specific battery installation requires consideration of all issues,
not just the technical issues considered in this document.
Purpose
The purpose of this document is to provide heating, ventilation,
and air conditioning (HVAC) and battery system designers and users
with information and recommendations concerning the ventilation and
thermal management of stationary battery installations.
