Foreword
This standard is drafted according to rules given by GB/T 1.1-2009.
This standard replaces GB/T 19049-2003 Water-source heat pumps. The main technical changes are as follows, compared with GB/T 19049-2003.
- Add the ?€?surface water type?€? in type;
- Change the name of underground loop type into ?€?buried pipe type?€?;
- Change the ?€?inlet-outlet water temperature difference 5??C at heat-source side under working condition of hot-cold water models?€? to ?€?the combination of outlet water temperature and water flow?€?;
- Change the heat pump from 8-gears to 2-gears, according to cold classification; - Modify the working condition; the working condition of centrifugal units and volumetric units are determined separately;
- Add the annual coefficient of performance (ACOP) as the energy efficiency index of heat pump unit.
This standard was proposed by China Machinery Industry Federation.
This standard shall be under the jurisdiction of China technical standardization committee of cooling and air conditioning equipment (SAC/TC 238).

1 Scope
This standard specifies the terms and definitions, types and basic parameters, requirements, test methods, inspection rules, marking, packaging, transport and storage of water source (ground-source) heat pumps (hereinafter referred to as ?€?UNIT?€?). This standard applies to water source heat pumps that use electromechanical compression cooling system and takes the water circulating in buried pipes or water in wells, lakes, rivers, oceans, sewage, industrial waste, or water in common pipelines as cold (hot) source.

3.1.5
Ground-loop heat pumps
The UNIT that uses water circulating in underground coil as cold (hot) source. 3.1.6
Surface-water heat pump
The UNIT that uses water in lakes, rivers, oceans, sewage, industrial waste, or other surface water as cold (hot) source.
3.2
(ACOP) Annual Coefficient of Performance; ACOP
The annual coefficient of performance obtained by comprehensively WEIGHTING the efficiency for water-source (ground-source) heat pumps when operating at full-load under nominal cooling conditions and nominal heating conditions WITH several office buildings in typical cities according to the ratio of cooling and heating time.
Annual coefficient of performance ACOP = 0.56EER+0.44COP
Note 1. EER is the energy efficiency of water (ground) heat pump when the UNIT runs at full capacity under rated cooling condition.
Note 2. COP the energy efficiency of water (ground) heat pump when the UNIT runs at full capacity under rated heating condition.
Note 3. The weighting coefficients, 0.56 and 0.44, are the proportion of cooling and heating time of office buildings in Beijing, Harbin, Wuhan, Nanjing and Guangzhou that accounts for the total air-conditioned time of office buildings.
