  • Patent number: 9027847
    Abstract: A method of estimating a floor temperature of a solid floor that has a fluid conduit embedded in the floor. Provided is a control scheme that provides a sequence, where the concrete temperature can be estimated through the temperature of the fluid in the conduit embedded in the floor. After the concrete temperature is obtained, a heating sequence can be initiated for providing fast and accurate control of the floor temperature.

  • Patent number: 8708244
    Abstract: The invention provides a method and a system for controlling floor heating or climate regulating systems with long time constants. According to the invention, a flow of a fluid is provided through the floor or through a similar medium with large thermal inertia. An induced heat is determined by adding up a plurality of differences between an inlet temperature of the fluid when it enters the medium and an outlet temperature of the fluid when it leaves the medium. The temperatures are sampled with a fixed sampling time and within a fixed period of time, and a corresponding change in temperature of the medium over the fixed period of time is determined. In the future, the temperature of that medium is controlled by use of a ratio between the induced heat and the change in temperature.

  • Patent number: 8121734
    Abstract: The invention provides a method for controlling the climate of an environment, e.g. a house, which exchanges thermal energy with an ambient space. Energy is supplied to the environment e.g. by radiators, floor heating, electrical heating fans etc. According to the method, a numerically expressed comfort criteria, and a numerically expressed weight of importance of compliance with the comfort criterion are defined. Subsequently, a supply of a specific amount of energy is considered, and with respect to that amount, a numerical expression of a degree of compliance with the comfort criterion, and a numerical expression of costs related to the supply of that amount of energy are provided.
