JJF 1768-2019 Rules of Metrology Testing for Energy Efficiency of Heat Pump Water Heaters

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 heat pump water heaters (devices) that rely on electric motors for drive, adopt steam compression refrigeration cycles, use air as a heat source, and are designed to provide hot water.
This standard applies to the supervision and inspection of the energy efficiency of heat pump water heaters (devices). For commissioned inspections, this standard can be used as a reference. Units that produce and sell heat pump water heaters (devices) can also refer to this standard for inspections.
This standard does not apply to water-source heat pump water heaters (devices).
The heat pump water heaters (devices) subject to inspection should be products that have passed the manufacturer's self-inspection, or goods imported and sold by sellers.
