The color system established in Rio Grande do Sul to authorize or prohibit activities in commercial or industrial establishments, has created a new reality for many companies and organizations. The prevention of the spread of COVID-19 meant that some were already alternating opening and closing while others remained for long closed periods. In view of this scenario, ASBRAV's warning is for everyone to always be attentive to the proper care with the air conditioning systems.
“To give an example of a problem that can be very common, just think of offices or commercial buildings that have been closed for a long time. Standing still, the equipment may have standing water inside, which generates the proliferation of bacteria and fungi. air conditioning When turned on, this air is thrown into the environment causing a risk of a series of respiratory diseases ”, explains the director of Air Quality of the South Brazilian Association of Refrigeration, Air Conditioning, Heating and Ventilation ( ASBRAV ), Mário Henrique Canale.
The first recommendation for those who are organizing a resumption is to clean the equipment. In addition, the professional warns of the importance of adequate air renewal. It is essential to note that Split-type equipment does not promote this renovation on its own, requiring the installation of specific equipment for this, easily found on the market.
The General Directorate of Health (DGS) considers that the risk of transmission of the new coronavirus motivated by the use of air conditioning in closed spaces is very low, as long as the maintenance rules are complied with and the space is ventilated.
the World Health Organization (WHO) issued a statement on the transmission routes of SARS-CoV-2, in which it reiterates that the transmission of the virus occurs mainly through secretions and droplets and the close contact with infected persons, not excluding the possibility of aerosol transmission.
It is a technology that dries the condensation of the evaporation system, preventing the growth of mold in the air conditioning system, which can cause odor during hot weather conditions. “After the engine is switched off and the condensation drains from the evaporation system for approximately 30 minutes, After-Blow is activated for 10 minutes to dry the evaporator and any remaining condensation in the air passage.
The air conditioning system automatically allows an air flow to enter from outside during this period, in order to prevent the accumulation of moisture ”, explains the brand in an official statement. “The technology uses an intelligent battery sensor (IBS) that monitors the battery making it stop working if the battery is low, eliminating any kind of concerns regarding battery discharge. This technology is also disabled when the air conditioning system is not used for a certain period of time, or when the outside temperature is low,
