房空調機に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an air conditioner that utilizes solar energy, and more particularly to a cooling air conditioner that efficiently utilizes the electrical output from a solar panel.
従来の太陽電池出力を利用する冷房空調機は太陽電池の
直流電力を商用の交流電源と同じ仕様の交流電力に変換
し空調機に電力を供給していた。Conventional cooling air conditioners that use the output of solar cells convert the DC power from the solar cells into AC power with the same specifications as commercial AC power sources, and supply the power to the air conditioner.
このために電力の変換の損失が生じ、しかも部屋の温度
が適温となった場合は余剰の電力を無駄に消費する欠点
がある。This causes a loss in power conversion, and furthermore, when the temperature of the room reaches an appropriate temperature, there is a disadvantage that surplus power is wasted.

プの運転・停止のオン・オフ制御をしているため、ポン
プの停止正時に余剰の電力を無駄に消費する。Conventional air conditioners, for example, convert direct current to alternating current and use an alternating current induction motor, as disclosed in Japanese Patent Application Laid-Open No. 56-91630, resulting in power conversion loss and the need to operate a compression pump for refrigerant circulation. Because the pump is controlled to turn on and off, surplus electricity is wasted when the pump stops on the hour.

る。In the present invention, power from the solar panel is directly supplied to the DC motor to drive the compression pump, and surplus pressurized refrigerant is stored in the voltage tank, and when the power supplied from the solar panel is insufficient, the pressure reduction tank is used. By emitting solar energy, it is possible to create an air conditioner that efficiently utilizes solar energy.

がある。FIG. 1 shows an embodiment of the present invention, in which the electrical output from a solar panel 1 is transferred to a refrigerant compression pump 2 driven by a DC motor, and a ventilation system 77 for an outdoor heat exchanger 6 and an indoor heat exchanger 7. 5'. The indoor temperature detector 9 detects the opening degree of the valve of the adiabatic expansion adjustment device provided upstream of the adiabatic expansion pipe 13.
By controlling the amount of refrigerant that expands adiabatically, the indoor temperature can be adjusted. In addition, surplus refrigerant is stored in the voltage tank 3, and when the power supply from the solar panel 1 is insufficient, the excess refrigerant is stored in the pressure reduction tank 4.
is released. In this way, since the power from the solar panel 1 is directly supplied to the DC motor, there is no exchange loss such as AC/DC conversion, and surplus energy is stored and released when there is a shortage, so solar energy can be used efficiently. Effects 1 FIG. 2 is a diagram showing the effects of the present invention. As shown in Figure 2 (a), when the amount of solar radiation suddenly decreases and there is no power supply from solar cells or external commercial power sources,
(in the same figure), if there is no voltage tank, the air conditioner cannot remove heat as shown by the dotted line. However, as in the present invention, in an example in which a 10 atm voltage tank and an expansion tank of the same volume are installed at a length of approximately 0.26 m, heat can be removed for approximately 40 minutes, as shown in the figure. effective.

A backflow prevention diode 12 to the battery panel 1 is added. For this reason, when the power from the solar panel 1 is sufficient to operate the air conditioner, the power from the direct light power source 10 is completely cut off and no power is consumed, resulting in the effect that power can be used effectively.
