Claim:
1. A virtual thermostat to control a target-zone-temperature of a target zone in an HVAC controlled space, comprising: a. a real time 3D scanner to provide a 3D point cloud raw data of said HVAC controlled space; b. a processor to reconstruct a 3D model of said HVAC controlled space using said 3D point cloud raw data and a CAD software; c. a control panel for a user to input a set of boundary conditions comprising of a set of dimensions of an interior and an exterior walls of said HVAC controlled space, a set of boundary wall temperatures, an outside temperature, and a set of wall thermal resistances, and a set of initial conditions comprising of a set of initial HVAC controlled space temperatures, an initial air inlet velocity, and a desired target zone temperature at said target zone inside said HVAC controlled space; d. a fluid flow processor having means to read said 3D model and to determine a spatial velocity and temperature distributions throughout said HVAC controlled space, and to calculate an average target zone temperature for said target zone; and e. a control system to turn an air inlet flow ON and OFF to control said target zone temperature by comparing said average target zone temperature with said desired target zone temperature, whereby said virtual thermostat controls said target zone temperature inside said HVAC controlled space without an actual temperature measurement in said target zone.
