System and method for monitoring a state of a fluid in an indoor space as well as a climate control system

A climate control system for controlling a climate in an indoor space, the climate control system including a monitoring system and a data processor, the monitoring system comprising:

• an input unit comprising a plurality of temperature sensors to obtain temperature measurement data (y1Tk, y2Tk, . . . , ymTk) indicative for a temperature field in said indoor space,
• a simulation unit to simulate fluid in said indoor space according to an indoor climate model, and to provide a predicted state of said fluid including at least a predicted temperature field (Tp) and a predicted flow field for the fluid in said indoor space,
• a comparison unit to compare the predicted temperature field with the temperature measurement data, and
• a state correction unit to provide a corrected state of the fluid based on a comparison result of said comparison unit,
• wherein the data processor receives, as an input, the predicted state of said fluid and providing, as an output, one or more control signals indicative of the corrected state of the fluid, and
• wherein the one or more control signals are provided to one or more actuators configured to change at least one variable of the climate in the indoor space, said one or more actuators selected from a heater, an air conditioner, a ventilator, a pump, a humidifier, or a dryer.
