Scope

This standard specifies the energy efficiency measurement requirements, measurement and inspection procedures, measurement and inspection methods, evaluation criteria for measurement and inspection results, and inspection reports for water/ground-source heat pump units used for household, commercial, and similar purposes, which are powered by electric mechanical compression systems and use water as the cooling (heating) source.
This standard applies to the supervision and inspection of the energy efficiency of water/ground-source heat pump units. For commissioned inspections, this standard can be referenced. Units that produce and sell water/ground-source heat pump units can also conduct inspections in accordance with this standard.
This standard does not apply to single-cooling and single-heating water/ground-source heat pump units.
The water/ground-source heat pump units subject to inspection should be products that have passed the manufacturer's self-inspection, or goods imported and sold by the seller.
