Miraco – Carrier Laboratories

Miraco – Carrier Laboratories
History:
Miraco labs were established in 1992 to serve the testing of air conditioning units for
research & development purpose. It is the first accredited A/C lab in Egypt since
2005.The labs are accredited by The Egyptian Accreditation Council (EGAC) according
to ISO/IEC 17025:2005 standard. Also it is the first A/C lab in Egypt to get the ESMA
(Emirates Authority for Standardization & Metrology) recognition certificate in 2012.
Scope of Testing:
Performance, Acoustics, Vibration, Reliability and Safety testing for A/C units including
split, package, WRAC, fan coils, air cooled, water cooled, water chillers & refrigeration
units from residential, light commercial to commercial units.
Current Labs:
1- Psychrometric Residential Lab: In which residential and light commercial A/C units
up to 5 Tons refrigerant are tested using Air-Enthalpy testing methodology. This method
depends on calculating the air volume flow rate supplied by the tested unit and the
Enthalpy difference between the air inlet & outlet for the unit under test.
2- Balanced Type Calorimetric Lab: In which residential and light commercial A/C units
up to 5 Tons refrigerant are tested using heat balance methodology. This method depends
on balancing the heat loads inside the testing rooms with the cooling effect of the unit
under test.
3- Psychometric Commercial Lab: In which A/C commercial units up to 25 Tons
refrigerant are tested using Air-Enthalpy testing methodology. This method requires
calculating the amount air supplied by the tested unit and the Enthalpy difference
between the air & outlet of the unit under test.
4- Reverberation Room: In which noise sources are tested from 63Hz up to 10,000Hz
using 1/3 Octave band frequency analysis by measuring the sound pressure inside the
reverberation room.
5- Reliability and Safety Lab: In which residential and light commercial A/C units up to 5
Tons refrigerant are tested for reliability & safety tests according to Carrier & various
universal standards.
6- Vibration Analysis Lab: In which residential, light commercial and commercial A/C
units are tested by measuring structural & piping vibration that prevent Miraco products
from cracks failure and helps in significant noise reduction.
