High-temperature heat pumps

This document is a proposed New Zealand publicly available specification under the Standards and Accreditation Act 2015. Issued as a draft in this form, it provides the required statutory opportunity for consideration and comment by the bodies and persons having an interest in the technical specification. Heat pumps have been available for many years; however, recent advances in the technology have made them better suited to high-temperature applications where heat is delivered at a temperature greater than 50°C. The objective of this publicly available specification (PAS) is to provide good practice advice and information to support the adoption of energy-efficient heat pump systems for domestic, commercial, and industrial applications. This PAS is limited to the most common systems available, which are normally those that utilise a mechanical vapour compression cycle using electricity.
