すべく構成してある蓄熱装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a heat storage device that stores heat using electricity at night and uses the stored heat during the day. A plurality of latent heat storage bodies sealed in a heat storage body are placed in a heat storage tank, and the heat storage body is configured to store heat in the latent heat storage body by heat exchange with a heat transfer fluid that circulates between the heat storage tank and the heat load. The present invention relates to a heat storage device.
この種の蓄熱装置においては、蓄熱完了時点にヒートポ

を何らかの方法で知る必要がある。そこで、従来は、前
記熱媒流体の蓄熱槽出入口の温度差と流量より、単位時
間毎の熱交換量を積算して蓄熱量を算出把握していた。This type of heat storage device requires operational control such as stopping the heat pump when heat storage is completed, so it is necessary to know the amount of heat storage by some method. Therefore, conventionally, the amount of heat storage has been calculated and grasped by integrating the amount of heat exchanged per unit time based on the temperature difference between the entrance and exit of the heat storage tank and the flow rate of the heat medium fluid.
しかしこの場合は、前記熱媒流体の流量を正確に測定し
ようとすると、データ送信用発信器を装備した高価な流

った。However, in this case, in order to accurately measure the flow rate of the heat transfer fluid, an expensive flowmeter equipped with a transmitter for transmitting data is required, and there is a loss due to heat radiation from the heat storage tank over time. I just couldn't get enough of the accuracy.
本発明は簡便でより正確に蓄熱量を把握できるものを提
供する点にある。An object of the present invention is to provide a method that allows the amount of heat storage to be grasped easily and more accurately.
本発明による特徴構成は

にあり、その作用効果は次の通りである。The characteristics of the present invention are as follows: (1) A flow rate adjustment mechanism is provided to adjust the inflow amount of the heat medium fluid into the heat storage tank and the outflow amount from the heat storage tank to set amounts; (2) This is due to the phase change of the latent heat storage material. (1) A liquid level displacement detector is provided to detect a displacement of the heat medium fluid level in the heat storage tank based on the volumetric expansion/contraction of the container; The functions and effects are as follows.
潜熱蓄熱体に蓄熱されていない基準状態で、熱媒流体の

状態を維持し乍ら、蓄熱を行うと、熱媒流体との熱交換
によって、潜熱蓄熱材のが相変化して膨張し、液面が上
昇する。The liquid level of the heat medium fluid in the heat storage tank is kept constant in a reference state in which no heat is stored in the latent heat storage body. In this case, as a flow rate adjustment mechanism, for example, the discharge amount of a pump that circulates the heat medium fluid is fixed to determine the circulating flow rate and the liquid level is kept constant. When heat is stored while maintaining this state, the latent heat storage material undergoes a phase change and expands due to heat exchange with the heat transfer fluid, and the liquid level rises.

タ式の液面計や連続測定が可能な光距離計等で液面を測
定し、この液面上昇量より第３図のグラフで示すように
、蓄熱量を算出できる。Then, as shown in Figure 1, for example, the liquid level is measured using a limit switch type or potentiometer type liquid level gauge that detects when the liquid level reaches the standard height, an optical distance meter that can perform continuous measurement, etc. As shown in the graph of FIG. 3, the amount of heat storage can be calculated from the amount of surface rise.

た。As a result, by controlling the liquid level displacement based on the volumetric expansion of the latent heat storage body, which is uniquely determined according to the amount of heat storage, it is possible to
Moreover, it has become possible to provide a heat storage device that can measure the amount of heat storage with a simple device without using an expensive flow meter.

(9), and a swing operation arm (17) is connected with a pin to the upper end of the float type operating member (8);
Thereby, the vertical movement of the float-type actuating member (8) is switched to rotational displacement, and a potentiometer-type tachometer (I8) provided at the pivot axis position of the swing operation arm (17) is provided to change the swing operation arm. (17) constitutes a liquid level displacement detector (19) that detects the rotational displacement of the heat transfer fluid (3) and detects the liquid level displacement of the heat transfer fluid (3). On the other hand, in the state before heat storage, the heat storage tank (10)
Since it is necessary to maintain a constant liquid level in the heat storage tank (10), the discharge amount by the circulation pump (6) is made constant, and the flow rate of the heat medium fluid (3) circulating through the heat storage tank (10) is made constant. This circulation pump (6) is called a flow rate adjustment mechanism that keeps the amount of outflow and inflow into the heat storage tank (10) constant.

(ΔH), and the amount of heat storage can be uniquely determined by detecting the displacement (ΔH) of the liquid level. Therefore, when the liquid level position reaches a displacement amount corresponding to a predetermined amount of heat storage, control is performed to output from the tachometer (18) and stop the heat pump (21) via the control means (20). .
