Testing of heat pumps PN-EN 14511, 16147 COP, SCOP

Testing of heat pumps PN-EN 14511, 16147 COP, SCOP

A heat pump, as defined in the PN-EN 14511-1 standard, is a set or sets enclosed in a housing, intended as a heat supply unit.

Heat pump tests performed at COCH are covered by the accreditation of the Polish system of research laboratories (accreditation of the Polish Center for Accreditation No.AB 308), and the license to use the international ILAC MRA mark, on the mutual recognition of test reports issued by accredited laboratories around the world.

The domestic heat pump market has been growing for many years. Due to the high interest of investors, it is highly probable that this trend will continue in the coming years.

The following trends are currently observed:
  • The dominant ground source for heat pumps is and will remain in the near future;
  • The fastest-growing segment of the heat pump market are pumps dedicated to domestic hot water (in this category, two-digit increases are recorded);
  • There is a growing interest in high power heat pumps for commercial, industrial and heating applications. These pumps usually use geothermal or hydrothermal energy.
For standardization reasons, we distinguish the following types of heat pumps:
  • heat pumps with electrically driven compressors for space heating – CO (PN-EN 14511);
  • heat pumps for the preparation of domestic hot water – DHW (PN-EN 16147);
  • heat pumps with electrically driven compressors such as ground (direct evaporation) / water (cooling) for space heating -CO (PN-EN 15879).
COCH Central Refrigeration Center in Krakow, meeting these trends, performs certified tests of heat pumps operating in air / water, water / water, chill / water systems, direct evaporation of the refrigerant / water. Tests are carried out in order to establish the energy and performance characteristics of factory-made devices with integral or separate condensers, factory-made devices with constant or adjustable capacity, autonomous interlocked devices and two-piece and multi-piece interlocked devices.
Types of tests performed:
Tests of heat pumps with electrically driven compressors for the preparation of domestic hot water (according to PN-EN 16147):
  • Heating period,
  • Determination of power consumption in working order,
  • Determination of useful energy,
  • Determining the COP efficiency index,
  • Electric energy usage,
  • Determining the reference hot water temperature and the maximum hot water volume.
According to PN-EN 16147, a heat pump for preparing domestic hot water is a heat pump, defined in PN-EN 14511-1, connected to a hot water storage tank or with a built-in storage tank.
Tests of heat pumps with electrically driven compressors for space heating (according to PN-EN 14511 standard):
  • Heating capacity,
  • Power consumed electric,
  • Heating efficiency COP.
Tests of heat pumps with electrically driven compressors such as soil (direct evaporation) / water (chill) for space heating (according to PN-EN 15879-1):
  • Determining the heating capacity,
  • Determination of electric power consumption,
  • Determination of the COP energy efficiency index.
