Introduction

In order to standardize the energy efficiency measurement and testing work of water (ground) source heat pump units that implement energy efficiency label management, this specification is formulated in accordance with the requirements of JJF 1261.1-2017 "Energy Efficiency Measurement and Testing Rules for Energy-using Products":

This specification is released for the first time:

Energy efficiency of water (ground) source heat pump units Measurement and detection rules

1 Scope

This specification stipulates that household, industrial and commercial use and similar applications that use electromechanical compression systems and water as the cold (heat) source Energy efficiency measurement requirements, measurement testing procedures, measurement testing methods, measurement of water (ground) source heat pump units for purposes Test results evaluation criteria and test reports, etc:

This specification applies to the energy efficiency measurement supervision and inspection of water (ground) source heat pump units: For entrusted inspection, please refer to this specification get on: Units that produce and sell water (ground) source heat pump units can also conduct inspections with reference to this specification:

This specification does not apply to single cooling and single heating water (ground) source heat pump units:

The water (ground) source heat pump unit to be tested should be a product qualified by the manufacturer's self-inspection, or imported by the seller, Products sold:
