産業上の利用分野
大発明は太陽熱利用温水給湯ｓ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 A major invention in the field of industrial application relates to a heat pump water heater for hot water supply using solar heat.
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−〇ＦＦ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、胤夜、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
止っている場合がある。これに伴って高温状態で最も多
く利用される夕方まで放置されるだめ貯湯タンクの自然
放熱による湯温低下が大きい。Conventional configuration and its problems Conventional solar heat pump water heaters operate in two ways: one is a solar irradiance sensing operation in which the compressor turns on and off depending on the output of the solar irradiance sensor, and the other is a solar irradiance sensing operation method in which the compressor is turned on and off depending on the output of the solar irradiance sensor, and a hot water storage tank is manually switched. In many cases, a manual operation system is installed in parallel with a manual operation system that operates continuously until the water temperature reaches a certain temperature. With this method, for example, on days with high solar radiation, such as in the summer, the solar irradiance sensor activates and the heat collection operation is started early, so it heats up early and operation is stopped during the hours when the solar radiation is highest. It may have stopped. As a result, the temperature of the hot water drops significantly due to natural heat radiation from the hot water storage tank, which is left unattended until the evening, when hot water is most frequently used.
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
にもなっていた。This has also caused a decrease in the calorific value ratio (hereinafter referred to as CoP) of the actually used hot water supply heat amount to the electrical input of the hot water supply system.
１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っても沸
上がっていないという問題が生じる。On the other hand, in the intermediate seasons (spring, autumn), there is little sunlight and both the water temperature and the outside temperature are low, so even if you drive after the sun starts shining, the water will boil even in the evening when you want to use it most. The problem arises that it is not.
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、早朝に沸上がっ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
低くする原因となっていた。In addition, in this case, if you switch to manual operation, if the temperature of the hot water storage tank does not reach a certain temperature, it will start operating even at night, so it will be in a boiling state in the early morning, and at the same time in the evening when it is most used. Until then, the hot water was left at a high temperature, which resulted in an extremely large amount of natural heat radiation from the hot water storage tank, causing a low COP.

In response to this, a heating control circuit is provided with a standard boiling mode that represents the standard temperature at any time of the day.
Furthermore, the compressor is turned to 0N according to the difference between the standard temperature at any set time and the hot water temperature in the hot water storage tank.
- A compressor drive circuit that is turned off is provided to always perform optimal heating control.

In FIG. 1, 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, and the water-refrigerant heat exchanger 4 and water circulation pump 6 , hot water storage tank 7 constitute a heating circuit, and hot water storage tank 7, hot water supply pipe 8, faucet 9, and water supply pipe 10 constitute a water supply 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 second one corresponds to the output (time) of the electronic timer 15.
The main storage device 16 records the standard boiling mode indicating the boiling temperature for each time as shown in the figure, and the output of the main storage device 16 at a certain time H8 (standard boiling temperature θW)

設計されている。Further, in the electronic timer 15, the number of oscillations of the oscillator 13 is counted by the time counter 14 based on the output of the sunlight sensor according to the sunlight illuminance at sunrise, and the number of oscillations of the oscillator 13 is counted by the time counter 14.
It is designed to call up the standard temperature from the 6 standard boiling modes.
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、ＩＳ′＋
泗Ｈ・−Ｊ−９＾沈・旧態−山詰品次／も−イ１゜入各
めに、貯湯タンク７の温度が高めの状態になっている。When driving in the summer, the water temperature is high and IS'+
The temperature of the hot water storage tank 7 is high for each 1 degree entry.
そこで、日照度セけ−１２の出力によって時刻が計数さ

び出した標準温度と、沸上げ温度センサー１１によって
検知された貯湯タンク７の湯温を、湯温比較器１８で比
較すると、貯湯タンク７の湯温の方が高く判定される。Therefore, when the time is counted based on the output of the solar irradiance sensor 12, the standard temperature at which the standard boiling mode was called in the main memory 16 and the hot water temperature in the hot water storage tank 7 detected by the boiling temperature sensor 11 are used. When compared by the hot water temperature comparator 18, the hot water temperature in the hot water storage tank 7 is determined to be higher.

所定の湯温が得られる。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 1' temperature comparator 18, and if the boiling temperature is determined to be low, compression is immediately performed. A phalange signal for compressor operation is input to the machine drive circuit 17 . As a result, the compressor is operated and the water in the hot water storage tank is boiled according to the standard boiling operation mode, and at a predetermined evening,

たがって、夏季運転と同様に運転が行なわれる。Moreover, in intermediate seasons (spring, autumn), the necessary boiling time is often insufficient just by trial operation. Even in this mid-season, the standard temperature in the standard boiling mode is compared with the hot water temperature in the hot water storage tank 7 at each time when the sunlight sensor 12 detects it and the time counter starts operating, and compresses the water according to its size. Controls the compressor drive circuit 17 and sets the compressor to zero.
