Contact information and request
We specialize in conducting certified tests of heat pumps that operate in various systems such as air/water, water/water, refrigerant/water and direct evaporation of refrigerant/water. Our tests are designed to establish energy and performance characteristics for different types of equipment:
- Heat pumps with integral or separate condensers
- Equipment with fixed or adjustable capacity
- Stand-alone and interlocked two- and multi-unit units
What types of heat pump testing does the COCH Laboratory offer?
What are the main types of heat pumps under investigation?
Various types of heat pumps are being studied, including heat pumps with electrically driven compressors for space heating, heat pumps for domestic hot water preparation, and heat pumps for space heating and cooling under partial load conditions.
What parameters are tested in the energy characteristics of heat pumps?
Parameters such as heating/cooling capacity, electrical input power, heating efficiency ratio COP and cooling efficiency ratio EER are studied as part of the energy characteristics of heat pumps.
What are the main objectives of heat pump performance testing?
The purpose of the performance tests is to verify the range of application specified by the manufacturer, test when the flow of heat transfer agents is closed, test when the electricity supply fails completely, check the defrosting system, and evaluate condensate drainage and sweat test of the housing.
What is the KEYMARK for heat pumps?
KEYMARK is a European certification mark confirming the compliance of products and services with European standards. A product marked with KEYMARK has been previously tested and certified by a neutral, independent and competent body, which ensures its quality and safety of use.
