CAN/CSA-C448 Series-02 (R2012)

C448.1-02 Scope 1.1 This Standard applies to unitary singleor splitliquidand groundheat pumps 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 applies to new and retrofit installations, and additions t o existing installations. 1.3 This Standard covers minimum requirements for equipment and material selection, site survey, system design, installation, testing and verification, documentation, and commissioning and decommissioning. 1.4 This Standard does not apply to director standingearth energy systems. 1.5 The values given in SI (metric) units are the standard. The values given in parentheses are for information only. 1.6 In this Standard, #shall# is used to express a requirement, ie, 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. Legends to equations and figures are considered requirements. C448.2-02 1. Scope 1.1 This Standard applies to unitary or split-system liquid-source heat pumps for single dwelling residential applications and other small building applications of up to and including 1400 m (15 000 ft ), using 2 2 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. Where appropriate, CSA Standard C448.1 may be used in lieu of CSA Standard C448.2. 1.2 This Standard applies to new and retrofit installations, and additions to existing installations. 1.3 This Standard covers system design, equipment selection, minimum installation requirements, test protocol, and information to be provided to the user and the equipment manufacturer. 1.4 This Standard does not apply to direct-expansion or standing-column-well earth energy systems. 1.5 The values given in SI (metric) units are the standard. The values given in parentheses are for information only. C448.3-02 1. Scope 1.1 This Standard applies to underground thermal energy storage systems (UTES) for space heating and cooling of all building types, and agricultural and industrial process cooling. 1.2 This Standard applies to new and retrofit installations, and additions to existing installations. 1.3 This Standard covers minimum requirements for equipment and material selection, site survey, system design, installation, testing and verification, design documentation, and start-up. 1.4 This Standards does not apply to direct expansion or standing column well earth energy systems. 1.5 The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
