Description

Under floor air conditioning terminal system with wireless communication technology}

The present invention relates to a floor air conditioning terminal system to which wireless communication technology is applied. More specifically, the floor air conditioning unit installed in the lower space of the indoor floor is configured to enable wireless communication, so that the floor air conditioning unit can be easily monitored and set. This relates to a floor air conditioning terminal system using wireless communication technology that can improve convenience.

In general, a floor air conditioning system uses the lower space of the indoor floor as an air conditioning supply space and supplies cooling and heating air to the room through an outlet provided on the floor. These floor air conditioning systems can be divided into pressurized and isobaric types. The pressurized floor air conditioning system maintains the plenum at a positive pressure compared to the room and supplies air to the room through the outlet on the floor, without using a separate fan. The isobaric floor air conditioning system is equipped with a plurality of fan terminal units (FTU, Fan Terminal Units) installed in the lower space of the floor and drives the fans to suck indoor air into the floor and mix indoor air with conditioned air. This is a method of supplying air indoors.

The isobaric floor air conditioning system has the advantage of being able to individually control each unit and flexibly apply it depending on the indoor space. However, in the event of a breakdown, each unit must be removed from the lower space of the floor to be repaired or replaced. There is this tricky problem.
