Embodiment Construction

[0028] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0029] When the intelligent temperature control valve adopts two-position start-stop control, the thermal delay will cause the room to be overheated or overcooled, resulting in discomfort and energy waste. The anticipation control is to adjust the time when the system starts heating and stops heating, and the control valve acts in advance before the room temperature reaches the user's set value. This not only keeps the room temperature basically within the temperature range set by the start-stop control, improves the control accuracy, but also achieves the effect of energy saving. The two control methods are shown as follows figure 1 shown. In the figure, 1—valve closing time point under expected control; 2—valve closing time point under double-position start-stop control; 3—valve o...

Abstract

The invention discloses an anticipatory control method for the overshoot of an intelligent temperature control valve in a household heating system, which comprises the following steps: Step 1, determining the superheat value of the overshoot or the subcooling value of the overshoot, and determining the overshoot for the first time The initial default data of the overshoot data is used for the superheat value or the overshoot value and the subcool value; step 2, judge the action to be executed; step 3, update the overshoot data. The invention can keep the indoor temperature within the set temperature range, improves the control precision, improves the user's comfort, and achieves the effect of energy saving.

Description

technical field [0001] The invention belongs to the technical field of smart home, and in particular relates to an anticipatory control method for the overshoot of an intelligent temperature control valve in a household heating system. Background technique [0002] Building heating systems generally have two methods: floor radiation heating and radiator heating. They use two heat exchange methods of heat radiation and heat convection to heat the room, and the thermal comfort is high. At the same time, in order to ensure the indoor temperature during heating, it is necessary to adjust the heat supply of the heating system. The adjustment methods of the heating system are: water supply temperature control (adjusting the heating water supply temperature), variable flow control (adjusting the heating water flow), start-stop control (setting the upper and lower limits of the temperature to control the system start and stop), intermittent adjustment (adjusting the heating heating...
