Preface:
This is the third edition of CSA B55.1, Test method for measuring efficiency and pressure loss of drain water heat recovery units. It supersedes the previous editions published in 2015 and 2012.
The intent of the test apparatus is to simulate conditions in which drain water heat recovery (DWHR) units are installed and to standardize these conditions between various laboratories that conduct this testing. This Standard is only intended to rate the performance of DWHR.
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
Scope:
1.1
This Standard specifies requirements for measuring the heat recovery efficiency and pressure loss for drain water heat recovery (DWHR) units.
1.2
This Standard applies to DWHR units
a) of any size; and
b) with a configuration where potable water and drain water flow rate is equal.
1.3
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 (non-mandatory) to define their application.
1.4
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.
