以下、本発明の一実施例につき添付図面に沿って詳細に
説明する。Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.
１は電気温水器、２は水熱源冷房ユニットの熱源側ユホ
ット、３は負荷側ユニットである。1 is an electric water heater, 2 is a heat source side unit of a water heat source cooling unit, and 3 is a load side unit.
また前記冷房ユホットは、圧縮機４、熱源側水熱交換器
５、絞り機構６、負荷側空気熱交換器７を一連の冷媒配
管により連結すると共に、負荷側ユニット３には室内フ
ァン８を配置している。In addition, in the cooling unit 4, the compressor 4, the heat source side water heat exchanger 5, the throttle mechanism 6, and the load side air heat exchanger 7 are connected by a series of refrigerant piping, and the load side unit 3 is equipped with an indoor fan 8. are doing.
また９はヒータ、１０は給湯管、１１は給湯栓であ１バ
循環ポンプ１２は電気温水器１の下部と熱源側水熱交換
器５の水入口を結ぶ水配管１３中に配置され、熱源側水
熱交換器５の水出口は水配管１４により給湯管１０に接
続されている。Further, 9 is a heater, 10 is a hot water pipe, 11 is a hot water tap, and a 1-bar circulation pump 12 is arranged in a water pipe 13 that connects the lower part of the electric water heater 1 and the water inlet of the water heat exchanger 5 on the heat source side. A water outlet of the side water heat exchanger 5 is connected to a hot water supply pipe 10 by a water pipe 14.
そして、電気温水器１と熱源側水熱交換器５を結ぶ水配
管１３の一部を用いて、放熱パイプ１５を形成すると共
に、放熱パイプ１５の冷却用ファン１６を設置し、前記
冷却用ファン１６を効果的に運転するものである。Then, a heat radiation pipe 15 is formed using a part of the water pipe 13 connecting the electric water heater 1 and the heat source side water heat exchanger 5, and a cooling fan 16 for the heat radiation pipe 15 is installed, and the cooling fan 16 is installed. 16 effectively.
さてその作用を説明すると、循環ポンプ１２の水量を絞
れば絞るほど、熱源側水熱交換器５における出入口水温
差は大きく得られる。Now, to explain its effect, the more the water volume of the circulation pump 12 is reduced, the greater the difference in water temperature between the inlet and outlet of the heat source side water heat exchanger 5 can be obtained.
したがって熱源側水熱交換器５の出口水温を給湯に必要
な高温水（例えば５５°Ｃ）になるごとく循環ポンプ１
２の水量を絞って運転を行うことにより、高温水は水配
管１４、給湯管１０を経て電気温水器１の上部より貯湯
されてゆく、電気温水器１中では、上部高温水と下部低
温水とがそれぞれの比重差により若干の境界層を形成し
て上下に分離され、運転が進むにつれ電気温水器１の上
部から高温水が供給され境界層が下部へ移動する。Therefore, the circulation pump 1 adjusts the outlet water temperature of the heat source side water heat exchanger 5 to the high temperature water (for example, 55°C) required for hot water supply.
2, high-temperature water is stored from the upper part of the electric water heater 1 through the water pipe 14 and the hot water pipe 10.In the electric water heater 1, high-temperature water in the upper part and low-temperature water in the lower part are stored. are separated into upper and lower parts by forming a slight boundary layer due to the difference in their specific gravity, and as the operation progresses, high-temperature water is supplied from the upper part of the electric water heater 1 and the boundary layer moves to the lower part.
したがって境界層が電気温水器１の下部に達する迄は熱
源側水熱交換器５へは冷却用ファン１６を作動せずに一
定した低温水が供給できるため、冷房サイクルが安定し
て運転できる。Therefore, until the boundary layer reaches the lower part of the electric water heater 1, a constant low-temperature water can be supplied to the heat source side water heat exchanger 5 without operating the cooling fan 16, so that the cooling cycle can operate stably.
しかるに境界層が電気温水器１の下部に達すると、熱源
側水熱交換器５へ送られる水温は急上昇してくる、熱源
側水熱交換器５への供給水温が上昇すると冷房サイクル
の高圧圧力が上昇しついには危険圧力迄達するため、冷
房運転不能となり、室内側で冷房が必要な時に運転でき
ない問題が生じる。However, when the boundary layer reaches the lower part of the electric water heater 1, the temperature of the water sent to the water heat exchanger 5 on the heat source side rises rapidly.As the temperature of the water supplied to the water heat exchanger 5 on the heat source side rises, the high pressure of the cooling cycle increases. As the pressure rises and finally reaches a dangerous pressure, it becomes impossible to operate the air conditioner, causing the problem that air conditioning cannot be operated when indoor cooling is required.
そこで、電気温水器１内の低温水が一巡し終って、熱交
換器５への供給水温が上昇し始め冷房サイクルが危険な
方向へ変化し始めたことを検知して冷却用ファン１６を
作動させることにより、電気温水器１の下部より送出さ
れる高温水が放熱パイブ１５で冷却され熱源側水熱交換
器５へ送られるため、冷房運転が安定して継続運転可能
となる。After the low-temperature water in the electric water heater 1 has completed its cycle, the temperature of the water supplied to the heat exchanger 5 begins to rise, and the cooling fan 16 is activated upon detecting that the cooling cycle has begun to change in a dangerous direction. By doing so, the high temperature water sent out from the lower part of the electric water heater 1 is cooled by the heat radiation pipe 15 and sent to the heat source side water heat exchanger 5, so that the cooling operation becomes stable and continuous operation is possible.
また冷却用ファン１６の運転は、循環ポンプ１２を流れ

できるため、タイマー起動としてもよいし、圧縮機４と
熱源側水熱交換器５を結ぶ高圧冷媒配管中に設けた圧力
検知器（図示せず）により冷却用ファン１６を起動させ
てもよいし、水配管１３中に設置した温度検知器（図示
せず）により冷却用ファン１６を起動させてもよい。In addition, if the flow rate flowing through the circulation pump 12 is constant, the operation of the cooling fan 16 can be calculated based on the capacity of the electric water heater 1, so it may be started by a timer, or the operation of the compressor 4 and the heat source side water heat exchanger 5 can be calculated based on the capacity of the electric water heater 1. The cooling fan 16 may be activated by a pressure sensor (not shown) installed in a high-pressure refrigerant pipe connecting the water pipes 13 or a temperature sensor (not shown) installed in the water pipe 13. You may also start.
なお電気温水器１は、給油回路に接続された蓄熱タンク
であればよく、放熱パイプ１５に放熱フィン等を付加し
たものも、本発明の範囲に含まれるものである。Note that the electric water heater 1 may be a heat storage tank connected to an oil supply circuit, and a heat radiation pipe 15 with heat radiation fins or the like added thereto is also included within the scope of the present invention.
本発明によれば、冷房運転しながら、蓄熱タンクに必要
な湯温、湯量を確保できることや、冷房排熱が取れ過ぎ
て、蓄熱量に限度がある場合にも、水道水をたれ流すこ
となく、任意の時間帯に冷房運転できるなどの優れた効
果を奏するものである。According to the present invention, it is possible to secure the necessary hot water temperature and amount in the heat storage tank while operating the air conditioner, and even when there is a limit to the amount of heat storage due to excessive cooling exhaust heat, there is no need to drain tap water. , it has excellent effects such as being able to operate the air conditioner at any time of the day.
