More and more often, engineering consultants and designers are asking for performance certifications as regards air conditioning units, not only under nominal operating conditions but also at different source temperatures and under various load conditions.
In many projects and technical specifications, builders must declare these data concerning the level of efficiency of their products in full safety conditions and with precision.
The projects focusing on energy saving concepts are based on these standard seasonal efficiency rates.
Hence the need to make sure that the contractual data for the product are as precise as possible, while testing the latter under climate conditions that reproduce the same ambient conditions of the installation site and especially using diversified load profiles with a view to certifying the machine performance levels at partial load conditions.
EMICON in order to achieve the goals outlined above serves the purpose of building, inside the factory, two performance climatic testing rooms under simulated environmental conditions.
It is an environment that is kept airtight from the outside, within which – through auxiliary and heat recovery systems – a controlled microclimate is created in terms of air temperatures, where fluids are treated according to the specific characteristics of the product being tested.
The types of machines that may be tested are :
- air or water cooled units
- available in a cooling version only or as heat pump with reversed cooling cycle.
Power levels are managed independently by the new climatic testing room:
- Cooling capacity from 5 to over 1000 kW
- Heating capacity up to 1600 kW.
The temperature range :
- For process fluids is from -5°C to 80°C.
- The temperature of the air flow entering the finned heat exchangers can be controlled up to a maximum of +52°C when, starting from -8°C as minimum inside temperature.
Galleon laboratory permits the performances measurement of water cooled chillers, heat pumps and 6-pipe units up to 1.500 kW and air cooled chillers up to 1.200 kW.
Yatch laboratory, allow the performances check of air and water cooled close control units up to a cooling capacity of 150 kW and an air flow rate of 30.000 m3/h.
Currently, if the required power is greater, it is possible to perform the test by dividing the operating phases of the unit in equivalent cooling circuits.
