Embodiment Construction

[0027] Hereinafter, regarding the control method of the thermal control valve of the present invention, specific embodiments thereof will be described in detail with reference to the drawings. figure 1 It is a circuit diagram showing an example of a control mechanism suitable for use in a control method of a thermal control valve. First, in figure 1 Among them, 10 represents the same thermal control valve as described above, and the thermal control valve has a PTC heater. 1 denotes a voltage regulator from which an output voltage is applied to the thermal control valve 10 . Also, 2 denotes a controller for controlling the output voltage of the voltage regulator 1 . In addition, 3 represents a fuse.

[0028] A first embodiment of a control method of a thermal control valve will be described. In this control method, as figure 2 As shown, first at the beginning (that is, when the valve starts to open), the voltage regulator 1 applies a voltage lower than the operating vol...

Abstract

Provided is a control method for a thermal valve, which does not need a rush current so high as that of the prior art so that it can be inexpensively constituted and which can acquire an excellent operation reliability. The control method controls a thermal valve (10), which is opened when fed with a predetermined operating voltage (Vr). In this method, a voltage (Va) lower than the operating voltage (Vr) is applied at first as an applied voltage only for a predetermined time period (t), thereby to drop the rush current. Next, the applied voltage is raised to the operating voltage (Vr) thereby to open the thermal valve (10). After lapse of a predetermined time period (T), a voltage (Vb) lower than the operating voltage (Vr) is continuously applied to the thermal valve (10) thereby to spare the consumed electric power.

Description

technical field [0001] The invention relates to a thermodynamic regulating valve, which is suitable for a temperature regulating device that circulates temperature regulating water to temperature regulating equipment such as a floor temperature regulating plate, and especially relates to a thermodynamic regulating valve capable of reducing the peak current when the valve is opened. Valve control method. Background technique [0002] A conventionally known heat pump type floor heating device is configured by connecting a warm water device including a water heat exchanger, a circulation pump, etc., and a floor heating panel capable of adjusting temperature by warm water through piping, and the water heat exchanger performs all heating and cooling operations. heat exchange between the hot water in the water circulation path and the refrigerant flowing in the refrigerant circuit (for example, refer to Patent Document 1 and Patent Document 2). In addition, in this heat pump type...
