Introduction

In order to standardize the implementation of energy efficiency labeling management of multi-unit air conditioning (heat pump) units (hereinafter referred to as "multi-unit Machine”) energy efficiency measurement and testing work, according to JJF 1261.1-2017 "Energy efficiency measurement and testing of energy-using products According to the requirements of the Rules, this specification is formulated. This specification is released for the first time. Multi-connected air conditioning (heat pump) unit Energy efficiency measurement and testing rules

1 Scope

This specification specifies the energy efficiency measurement requirements, measurement testing procedures, and Measurement and testing methods, measurement and testing results evaluation criteria and testing reports, etc. This specification applies to multi-line energy efficiency measurement supervision and testing, and commissioned testing can refer to this specification. Production and Sales of multi-line units can also refer to this specification for testing. The multi-line energy efficiency measurement and detection method specified in this specification is the air enthalpy difference method. This specification does not apply to units with dual refrigeration cycle systems and multiple refrigeration cycle systems. The multi-line tested should be products that have passed the self-inspection of the manufacturer, or the products imported and sold by the seller.
