ANSI/CSA C448 Series-16 - Design and installation of ground source heat pump systems for commercial and residential buildings

Preface

This is the first edition of the binational ANSI/CSA C448 Series, Design and installation of ground source heat pump systems for commercial and residential buildings. It supersedes the previous editions published in 2013 and 2002 under the title, Design and installation of earth energy systems.

The ANSI/CSA C448 Series now consists of the following parts:

a) ANSI/CSA C448.0, Design and installation of ground source heat pump systems — Genericapplications for all systems;

b) ANSI/CSA C448.1, Design and installation of ground source heat pump systems for commercial andinstitutional buildings;

c) ANSI/CSA C448.2, Design and installation of ground source heat pump systems for residential andother small buildings;

d) ANSI/CSA C448.3, Installation of vertical configured closed-loop ground source heat pump systems;

e) ANSI/CSA C448.4, Installation of horizontal configured closed-loop ground source heat pumpsystems;

f) ANSI/CSA C448.5, Installation of surface water (including submerged exchangers) heat pumpsystems;

g) ANSI/CSA C448.6, Installation of open-loop systems ground water heat pump systems;

h) ANSI/CSA C448.7, Installation of standing column well heat pump systems; and

i) ANSI/CSA C448.8, Installation of direct expansion heat pump systems.

ANSI/CSA C448.0 contains requirements applicable to any system within the scope of the ANSI/CSA C448 Series. ANSI/CSA C448.2 has alternative requirements for houses and small buildings. For systems within the scope of ANSI/CSA C448.2, either ANSI/CSA C448.1 or ANSI/CSA C448.2 may be followed. Underground thermal energy storage systems formerly, contained within previous editions of this Standard under CSA C448.3, has been removed with UTS-specific information distributed among amended, distributed among, and included within ANSI/CSA C448.0 and ANSI/CSA C448.1, where appropriate. This edition introduces requirements for standing column well systems.

ANSI/CSA C448.0-16 - Design and installation of ground source heat pump systems — Generic applications for all systems

Scope

1.1
This Standard applies to

a) direct expansion ground source heat pumps for systems using ground heat exchangers as a thermal source or sink for heating and/or cooling, with or without a supplementary heating source; and

b) unitary single package or split system liquid source and ground source heat pumps for all systems using groundwater, submerged heat exchangers, or ground heat exchangers as a thermal source or sink for heating and/or cooling, with or without a supplementary heating source.

1.2
This Standard also applies to thermal energy storage systems.

1.3
This Standard applies to new and retrofit installations.

1.4

1.5
This Standard applies to standing column well ground source heat pump systems.

1.6
The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.

1.7
In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.
