Concentration Limit The room in which the air conditioner is to be installed requires a design that in the event of refrigerant gas leaking out its concentration will not exceed a set limit The refrigerant R410A which is used in the air conditioner is safe without the toxicity or combustibility of ammonia and is not restricted by laws to be imposed which protect the ozone layer However since it contains more than air it poses the risk of suffocation if its concentration should rise excessively Suffocation from leakage of R410A is almost non existent With the recent increase in the number of high concentration buildings however the installation of multi air conditioner systems is on the increase because of the need for effective use of floor space individual control energy conservation by curtailing heat and carrying power etc Most importantly the multi air conditioner system is able to replenish a large amount of refrigerant compared with conventional individual air conditioners If a single unit of the multi conditioner system is to be installed in a small room select a suitable model and installation procedure so that if the refrigerant accidentally leaks out its concentration does not reach the limit and in the event of an emergency measures can be made before injury can occur In a room where the concentration may exceed the limit create an opening with adjacent rooms or install mechanical ventilation combined w
