Abstract
Official abstract text for this publication.
Controlling under surface heating/cooling by supplying liquid to at least two supply loops in an under surface heating/cooling system, and controlling the flow of the liquid on and off such that during the duty cycle the flow is high and between the duty cycles the flow is off. Room temperature is controlled by controlling the percentage of the duty cycles, which percentage is determined on the basis of the heating demand of the rooms. Different loops are controlled such that at least in two different loops the duty cycles start at different moments.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of controlling under surface heating/cooling, the method comprising supplying liquid to at least two supply loops in an under surface heating/cooling system, and controlling the flow of the liquid on and off such that during a duty cycle the flow is high and between the duty cycles the flow is off whereby room temperature is controlled by controlling a ratio of the duty cycle to a control time frame, the ratio being determined on the basis of the heating demand of the rooms, and each of the at least two supply loops is controlled such that a maximum ratio of the duty cycle to the control time frame is limited to 70%. 2. A method according to claim 1 , wherein at least in two different loops the duty cycles are performed at different times. 3. A method according to claim 2 , wherein at least in two different loops having essentially the same length the duty cycles are performed simultaneously. 4. A method according to claim 2 , wherein the duty cycle is significantly shorter than the overall time constant of the heating step response of the floor and room. 5. A method according to claim 1 , wherein at least in two different loops having essentially the same length the duty cycles are performed simultaneously. 6. A method according to claim 5 , wherein the duty cycle is significantly shorter than the overall time constant of the heating step response of the floor and room. 7. A method according to claim 1 , wherein the duty cycle is significantly shorter than the overall time constant of the heating step response of the floor and room. 8. The method of claim 1 wherein each of the at least two loops is controlled such that a minimum ratio of the duty cycle to the control time frame is limited to 15%.
