Just because your ammonia … Hofmann adds: “In addition, ammonia systems may only be operated by specially trained personnel. 1106.5 Remote controls. Extraction system inlets must be close to the machinery, have suitable guards, and must not be obstructed. Major differences can be found between codes when determining ventilation requirements for ammonia machinery rooms. Section 8.11.5 of ASHRAE Standard 15 (ASHRAE 2010) states: "The mechanical ventilation required to exhaust an accumulation of refrigerant due to leaks of a rupture of the system will be capable or removing air from the machinery room in not less than the following quantity: Q = 100 [square root of G] (Q = 70 [square root of G]) where Q = the airflow in cubic feet per minute (liters per second) and G = the mass of refrigerant in pounds (kilograms) in the largest … 4 IIAR BULLETIN 109 97-08-011.2 IIAR 109new.40 3/14/00 8:26 AM Page 4. Design and installation2. CMC 1110.1 (1)Thesuctioninletofacompressor,compressorunit,or CMC 1110.1 There is no lower limit. Ventilation & Emergency ventilation: Multiple fans or multispeed fans are allowed for temperature control and emergency ventilation of the machinery room. A “cut-off room” (having one or more exterior walls with doors leading directly outside) is acceptable.

The UMC change rec-ognizes that ANSI/IIAR 2 now includes content necessary to serve as both a code and a standard. Where refrigerants of Groups A2, A3, B2 and B3 are used, the machinery room shall conform to the Class 1, Division 2, hazardous location classification requirements of NFPA 70. Guidelines for Ammonia Machinery Room Ventilation. Location of ammonia refrigeration machinery is a detached building. Dear Sir we have ice cream production room with dimensions 40m*40m*5m and sometimes we face ammonia leakage so please how we make ventilation in short time.
