産業上の利用分野
本発明は太陽熱利用温水給湯機におけるヒート
ポンプ給湯機に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heat pump water heater in a solar hot water water heater.
従来例の構成とその問題点
従来の太陽熱利用ヒートポンプ給湯機の運転方
式は、日照度センサーの出力に応じて圧縮機が
ON−OFFする日照度検知運転方式と、手動的に
切り替えて貯湯タンクの湯温が一定の温度に沸上
がるまで、昼夜、運転する手動運転方式とが並設
されている場合が多い。この方式では、例えば、
夏季のように日射量の多い日では、日照度センサ
の作動により、集熱運転が早期より開始されるた
め、早目に沸上がり日射量が最も多い時間帯では
運転が止つている場合がある。これに伴つて高温
状態で最も多く利用される夕方まで放置されるた
め貯湯タンクの自然放熱による湯温低下が大き
い。このため、給湯システムの電気入力に対する
実利用の給湯熱量の熱量比（以後、COPと呼ぶ）
が低下する原因にもなつていた。Conventional configuration and its problems The conventional operation method of solar heat pump water heaters is to operate the compressor according to the output of the solar irradiance sensor.
In many cases, a solar illuminance sensing operation method that turns on and off, and a manual operation method that is manually switched and operated day and night until the water temperature in the hot water storage tank reaches a certain temperature are installed side by side. In this method, for example,
On days with high solar radiation, such as in summer, heat collection operation starts early due to the activation of the solar irradiance sensor, so it may heat up early and stop operating during times when solar radiation is at its highest. . As a result, hot water is left in a high temperature state until the evening when it is most frequently used, resulting in a large drop in water temperature due to natural heat dissipation from the hot water storage tank. For this reason, the calorific value ratio (hereinafter referred to as COP) of the actual amount of hot water supply to the electrical input of the hot water system
It was also the cause of the decline.
一方、中間季節（春、秋）においては、日射量
が少なく、水温および外気温が共に低いために、
日が照り出してから運転しても夕方の最も利用し
たい時刻になつても沸上がつていないという問題
が生じる。 On the other hand, in the intermediate seasons (spring, autumn), the amount of solar radiation is low and both the water temperature and the outside temperature are low.
Even if you start driving after the sun starts to shine, there is a problem that the water will not heat up even in the evening when you want to use it most.
また、この場合、手動運転方式に切替えると、
貯湯タンクの温度が、ある一定の温度に達してい
なければ、夜でも運転に入るため、早朝に沸上が
つた状態になると同時に、最も利用される夕刻ま
で、高湯温の状態で放置されるため、貯湯タンク
の自然放熱が極めて多く、COPを低くする原因
となつていた。 Also, in this case, if you switch to manual operation mode,
If the temperature of the hot water storage tank does not reach a certain temperature, it will start operating even at night, causing the water to reach a boiling point early in the morning and remain at a high temperature until the evening when it is most used. , natural heat radiation from the hot water storage tank was extremely high, which caused the COP to be low.

制御回路１９とから構成されている。DESCRIPTION OF EMBODIMENTS FIG. 1 shows a heat collection circuit, a heating circuit, a water supply circuit, and an electric control circuit of a solar heat pump water heater according to an embodiment of the present invention. FIG. 2 shows a standard boiling mode diagram that allows boiling to a constant temperature by a predetermined time in the evening according to an embodiment of the present invention. 1st
In the figure, a heat pump heat collection circuit is composed of a heat collector 1, an accumulator 2, a compressor 3, a water-refrigerant heat exchanger 4, and an expansion valve 5. The tank 7 constitutes a heating circuit, and the hot water storage tank 7, the hot water supply pipe 8, the faucet 9,
The water supply pipe 10 constitutes a water supply and hot water supply circuit. On the other hand, the electric control circuit includes an electronic timer 15 consisting of a solar irradiance sensor 12 disposed in the heat collector, a time counter 14 that counts the output of the oscillator 13 according to the output of the solar irradiance sensor 12, and The main memory 16 records the standard boiling mode indicating the boiling temperature for the time as shown in FIG. 2 in response to the output (time) of the electronic timer 15, and The output (standard boiling temperature θ W ) is compared with the output of the boiling temperature sensor 11 installed in the hot water storage tank (boiling temperature of the hot water storage tank), and the compressor drive circuit 17 is controlled depending on the magnitude. The heating control circuit 19 includes a hot water temperature comparator 18.

れている。 The main storage device 16 stores the operating mode that takes the longest operating time in winter as the standard boiling operating mode. Further, the electronic timer 15 is configured such that the number of oscillations of the oscillator 13 is counted by the time counter 14 based on the output of the sunlight sensor corresponding to the solar illuminance at sunrise, and at each time, the standard temperature is determined from the standard boiling mode in the main storage 16. is designed to call.
次に、上記実施例の作用、効果について説明す
る。 Next, the functions and effects of the above embodiment will be explained.
夏季の運転時においては、水温も高く、かつ、
貯湯タンク７の残湯量も比較的多くなつているた
めに、貯湯タンク７の温度が高めの状態になつて
いる。 When driving in the summer, the water temperature is high and
Since the amount of hot water remaining in the hot water storage tank 7 is relatively large, the temperature of the hot water storage tank 7 is high.

れ、標準沸上げ運転モードにそつて貯湯タンク内
の水は沸上げられ、所定の夕刻には、所定の湯温
が得られる。 Therefore, at the time when the time is counted based on the output of the sunlight sensor 12, the standard temperature at which the standard boiling mode was called in the main storage device 16 and the hot water storage tank 7 detected by the boiling temperature sensor 11 are used.
When comparing the hot water temperatures in the hot water tank 7 with the hot water temperature comparator 18, the hot water temperature in the hot water storage tank 7 is determined to be higher. Therefore, no command signal for compressor operation is output from the hot water temperature comparator 18 to the compressor drive circuit 17. On the other hand, as time passes, the standard boiling mode in the main storage device 16 and the output temperature of the boiling temperature sensor 11 are compared by the hot water temperature comparator 18, and if the boiling temperature is determined to be low, the compressor is immediately activated. A command signal for compressor operation is input to the circuit 17 . As a result, the compressor is operated and the water in the hot water storage tank is boiled in accordance with the standard boiling operation mode, and a predetermined hot water temperature is obtained at a predetermined evening.
また、中間季節（春季、秋季）では昼間運転だ

沸上げ動作が行なわれる。 Furthermore, during mid-seasons (spring, autumn), daytime operation alone often does not provide enough boiling time. Even in this mid-season, the standard temperature in the standard boiling mode and the water temperature in the hot water storage tank 7 are compared at each time when the sunlight sensor 12 detects it and the time counter starts operating, and the temperature is determined according to the magnitude. to control the compressor drive circuit 17 and turn on the compressor.
OFF control. In this case as well, the standard boiling mode is set and the operation is performed in the same way as the summer operation. In winter, the boiling operation is similarly performed according to the standard boiling mode.
