Operation of the Pressure Switch in Air Conditioning Systems

The invention of the pressure switch opened the door to a series of applications and advances in the development of equipment and systems. Basically the pressure switch is an electromechanical pressure switch. Pressure measurement is a given environment is measured mechanically and. when reaching a predetermined point an electrical contact opens or closes.

Several applications benefit from the pressure switch for its operation, including air conditioning systems. Large room air conditioning systems work based on the distribution of the cooled air among all rooms through ducts. However, as they are difficult to access and monitor, sometimes these ducts accumulate dirt, dust and waste, which in addition to contributing to poor air quality can compromise the functioning of the entire chilled air distribution system.

How the pressure switch works: in this case, the pressure in the system is measured at several points. The pressure switches, installed at different points, monitor this pressure and, in the indication of a drop or increase in pressure at a certain point, a reduction in the flow capacity of the air through the system is demonstrated, indicating possible blockages.

In these cases, there are several problems, from the considerable increase in the consumption of electricity, the inefficiency of the system to the compromise of the quality of the distributed air, with the accumulation of dirt and the proliferation and spread of viruses and bacteria.
