本発明はソーラーヒートポンプ冷暖房装置に関し、更に
詳細には太陽熱と大気熱の両方をオ０用して暖房を行な
う直膨式ヒートポンプの制御装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar heat pump air conditioning system, and more particularly to a control system for a direct expansion heat pump that performs heating using both solar heat and atmospheric heat.
従来、この種のヒートポンプ冷暖房装置では、日射の強
弱に応じて室外ファンをオン又はオフしていた。Conventionally, in this type of heat pump air conditioning system, an outdoor fan has been turned on or off depending on the strength of solar radiation.
このため、日射量のみでは充分な暖房能力が得られない
場合、室外ファンをオンして大気からも吸熱を行゛なう
必要があった。しかし、一般的に、この室外ファンの風
量は外気低温時でも設計能力を確保するために大風量の
ものが備えられている。Therefore, if sufficient heating capacity cannot be obtained from solar radiation alone, it is necessary to turn on the outdoor fan to absorb heat from the atmosphere as well. However, in general, this outdoor fan is equipped with a large air volume in order to ensure the designed capacity even when the outside temperature is low.
そのため、−産室外フアンがオンすると消費電力が急に
増加し、成績係数も低下するという欠点があった。Therefore, when the fan outside the delivery room is turned on, the power consumption suddenly increases and the coefficient of performance also decreases.
従って、本発明の目的は、叙上の従来の欠点を除去すべ
く日射量に応じて室外ファンの風量を制御して室外コイ
ルでの大気からの吸熱量を適当に制御することによシ、
日射量での不足分のみを大気熱で補うソーラーヒートポ
ンプ冷暖房装置を提供することにある。Therefore, an object of the present invention is to eliminate the above-mentioned conventional drawbacks by controlling the air volume of an outdoor fan according to the amount of solar radiation and appropriately controlling the amount of heat absorbed from the atmosphere by the outdoor coil.
An object of the present invention is to provide a solar heat pump air-conditioning device that makes up for only the shortfall in solar radiation using atmospheric heat.

。The solar heat pump air conditioning system of this embodiment includes a compressor 1, the discharge side and the inlet side of which are connected to a refrigerant circulation circuit via a four-way switching valve 2. In this refrigerant circulation circuit, an indoor coil 4 having an indoor fan 3, an expansion valve 5, an outdoor coil 7 having an outdoor fan 6, and a solar heat collector 8 are arranged in this order. The solar heat pump air conditioning system of this embodiment further includes a solar radiation detector 9 and a control device 10, the solar radiation detector 9 is electrically connected to the control device ft 10 K, and the control device 10 is connected to the outdoor coil. It is electrically connected to the outdoor fan 6 of 7.

ままである。In such a sealer heat pump air conditioning system,
During heating operation, high-temperature, high-pressure refrigerant gas discharged from the compressor 1 passes through the four-way switching valve 2, flows through the refrigerant circulation circuit in the direction of the solid arrow in the figure, enters the indoor coil 4, condenses and liquefies, and then passes through the expansion valve. 5 and the pressure is reduced. Then, the refrigerant gas is heated by solar radiation in the solar collector 8 and evaporated. If sufficient heating capacity can be obtained using only this latent heat of evaporation, there is no need for the outdoor coil 7 to absorb heat, and therefore the outdoor fan 6 remains stopped.
しかし、日射が減少して太陽熱コレクタ８での吸熱量が
減ると次第に蒸発温度が低下していく。However, as the solar radiation decreases and the amount of heat absorbed by the solar heat collector 8 decreases, the evaporation temperature gradually decreases.

ことなく光分に日射を利用することができる。In this manner, when the evaporation temperature reaches the atmospheric temperature or lower, heat absorption in the outdoor coil 7 begins. However, this amount of heat absorption is sufficient to compensate for the decrease in heat absorption by the solar heat collector 8, so it is not necessary to rotate the outdoor fan 6 at full speed. Therefore, upon receiving the signal from the solar radiation detector 9, the 1bυ control device 10 gradually increases the rotation speed of the outdoor fan 6 in accordance with the decrease in the solar radiation. As a result, solar radiation can be used for light without wasting power for the outdoor fan 6.
