T/CAS 302-2018 Performance specification for multi-loop low ambient temperature air source heat pump heaters
Basic Information
Scope
Scope: This standard specifies the terms and definitions, requirements, test methods, inspection rules, marking, packaging, transportation, and storage for multi-unit low-ambient-temperature air-source heat pump fan heaters. This standard applies to multi-unit air-source heat pump fan heaters that use fully enclosed motors-compressors, and whose condensers and evaporators all employ air-cooled heat exchangers, with a nominal heating capacity of 16 kW or less. These products are designed to create comfortable indoor environments and operate in ambient temperatures of no less than -25°C, hereinafter referred to as "multi-unit fan heaters". This standard does not apply to the following products: - Multi-unit air-source heat pump fan heaters with a nominal heating capacity greater than 16 kW; - Duct-blower-type low-ambient-temperature air-source fan heaters that generate hot air.
