ASHRAE - Machinery Room Ventilation Published by ASHRAE | Written by Dr. Andy Pearson The amount of ventilation required in refrigeration machinery rooms is one of the topics receiving a lot of attention in recent years in safety standards committee meetings around the world. Total Mechanical & electrical space requirements range between 4 & 9 % of gross building area. A mechanical room or a boiler room is a space in a building dedicated to the mechanical equipment and its associated electrical equipment. I would like to provide ventilation to the space to handle this load. The most important is not to exceed the permissible maximum temperature. International Mechanical Code (IMC) for commercial buildings specifically include provisions for ventilation and related issues and are commonly used by states and communities, and are included. While most mechanical design engineers are familiar with ASHRAE Standard 62.1: Ventilation for Acceptable Indoor Air Quality, many are only familiar with the versions they’ve used through their careers-most use it to satisfy code or permit requirements or to achieve credit compliance for a high-performance building standard.The standard is best known for its Ventilation Rate … Limit values for humidity and air quality, e.g. %PDF-1.5 %���� ��Y�$h��6�c�h�g�l�#�$���_B�����%\��~��vA��6Ϭ�)O_�~�?_"���y�,���Hs���ۀ��bfB�N"�����ڸ�,�d=`����#P��~;k4�w���2�����{��(�@�̨�2�d<=�%6��� �It���f�Г����+��Ҡ⯤���r��O"�PmD܈��� ����Wϐ�h�%��x[����|3��==�a'۞��X���&~�l���Cm�bh��*�Z���D���1�D�޲��4��|p�ol�[F!�ؔ�Yf�{^ڶ2~'�\h������B�ي R�4�zb�S���ۍ�~��n�r�9�:ă:Iȉ�'W�d��t. 20 0 obj <>/Filter/FlateDecode/ID[<764ED921F1C6C28BF02A0EFFD25C054A><64EBEB27E062674BBBEF2DF5FBB3F1F5>]/Index[10 24]/Info 9 0 R/Length 66/Prev 18404/Root 11 0 R/Size 34/Type/XRef/W[1 2 1]>>stream If mechanical ventilation is being used, 0.35 CFM of air per each 1,000 BTU/hr of gas burning equipment must be added. h�bbd``b��WA�1H��|Ӏ�ak)��M\A@�#H���XV@�;H�����$� ��ML��@�(1����a0҈��q>���8q�h��8��h��8�}4�G�k4�G�j��hn�vďa���t� N�#A Mechanical ventilation is often provided by equipment that is also used to heat and cool a space.
