24. Caution for Refrigerant Leaks
24.1 Introduction
The installer and system specialist shall secure safety against leakage according to local regulations or standards. The following
standards may be applicable if local regulations are not available.
The VRV System, like other air conditioning systems, uses R410A as refrigerant. R410A itself is an entirely safe non-toxic, non-combustible
refrigerant.Neverthelesscaremustbetakentoensurethatairconditioningfacilitiesareinstalledinaroomwhichissufcientlylarge.Thisassures
that the maximum concentration level of refrigerant gas is not exceeded, in the unlikely event of major leak in the system and this in accordance to
the local applicable regulations and standards.
Maximum concentration level
The maximum charge of refrigerant and the calculation of the maximum concentration of refrigerant is directly related to the humanly occupied
space in to which it could leak.
The unit of measurement of the concentration is lbs./ft.
3
(kg/m
3
) (the weight in Ibs. (kg) of the refrigerant gas in 1 ft.
3
(1 m
3
) volume of the occupied
space).
Compliance to the local applicable regulations and standards for the maximum allowable concentration level is required.
Direction of the
refrigerant flow
Room where refrigerant leak has occurred
(outflow of all the refrigerant from the system)
Pay special attention to places, such as basements, etc. where refrigerant could stay, since refrigerant is heavier than air.
