T/GDC 31-2019 Pool constant temperature heat pump dehumidifier equipment
Basic Information
Scope
Scope: This standard specifies the terms and definitions, types and basic parameters, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of heat pump equipment for pool heating and dehumidification. This standard applies to heat pump water heaters driven by electric motors and using a vapor compression refrigeration cycle, with air as the heat source, for providing hot water for swimming pools. Air-source heat pump water heaters for other similar purposes can also be used as a reference; Main technical contents: General requirements, safety requirements, airtightness, heating capacity, heating power consumption, coefficient of performance (COP), water-side pressure loss, operation, maximum load conditions, defrosting conditions, low-temperature conditions, variable-condition requirements, noise, salt spray resistance, and coating adhesion.
