The environment where the air conditioner is installed needs to be designed so that, if a refrigerant gas leak occurs, its concentration does not exceed the established limit.
The R - 407C refrigerant used in the air conditioner is safe, does not have the toxicity or combustibility of ammonia, and its use is not limited by laws protecting the ozone layer. However, as it contains more than just air, there is a risk of suffocation if its concentration rises too high. Suffocation due to leaks is almost non-existent. With the recent increase in buildings with large concentrations, the installation of multiple air conditioner systems is increasing by
because of the need for efficient use of floor space, energy conservation by reducing heat and conductive force, etc.
Most importantly, the multiple air conditioner system is capable of replacing a large amount of refrigerant when compared to individual air conditioners. If only one unit of the multiple conditioner system is installed in one
small environment, choose a model and adopt installation procedures so that in the event of accidental leakage of refrigerant, its concentration does not reach the limit (and in case of an emergency, measures can be taken before injuries occur).
In an environment where concentration limits can be exceeded, create an opening for adjoining environments, or install mechanical ventilation combined with a gas leak detection device.
