Pressure switches are used in numerous applications in the industry, as well as systems that are part of our daily lives. One such application is air conditioning systems.
An air conditioning system is made up of a cooling plant and ducts, responsible for the distribution of refrigerated air throughout the environment, as well as ducts that capture the ambient air and return it to the cooling plant, thus providing the renovation of the entire cooling system. the ambient air.
These air collection and distribution systems have filters, responsible for air purification, filtering solid particles, or even contaminants and pathogens, to protect the environment from the spread of a virus, for example.
One of the challenges is maintaining these filters. Clogging, or even decreasing filtering capacity of filters, in addition to compromising the air purification capacity, compromises the air circulation capacity in the environment, increasing the system energy consumption and reducing its cooling capacity.
The use of differential pressure switches is intended to monitor air flow between all process steps. The pressure switch measures the pressure in the duct before air passes through the filter. The difference in pressure between these two environments indicates the possibility of filter clogging or even reduced air flow. This measurement serves as an alert for maintenance personnel to check the filter in question, or even to check the condition of the ducts, the existence of breakages, etc.
