BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] In large gatherings like auditoriums, seminar halls, cinema halls and conference rooms, most of time audience is not comfortable with cooling of heating, ventilation and air conditioning system (HVAC system). Some of the audience in one portion of room feels cold while others feel hot. Audience don`t alter preset temperature of HVAC system or if they change, they have to change the preset temperature manually or ask somebody else to assist. This results in wastage of electrical energy as the HVAC systems tend to run for longer time even when the audience are feeling cold or hot
[0004] Other solutions can include wireless control of HVAC system or switching off partial HVAC system which creates comfort for one type of audience in room but creating discomfort for other audience. The wireless control of HVAC does not take into account the comfort level of all the audience in the room. These types of solutions does not offer control of all the HVAC units and thus unable to control all HVAC units under one controller. A solution that controls the HVAC units automatically according to optimum temperature requirement for the audience is required.
[0005] There is a need to overcome above mentioned problems of prior art by bringing a solution that facilitates controlling the HVAC units under one controller and enables maintaining optimum temperature range in a room according to requirement of user. Also, the solution helps in saving electric power and cut cost of electrical energy resource.
