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).

Water source (ground-source) heat pumps
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.
