よい装置とはいえなかった。[Problems to be Solved by the Invention] In the conventional heat pump type air-conditioning/heating water supply device as described above, the plurality of hot water storage tanks are each independently arranged. For this reason, each hot water storage tank requires one pressure reducing device (capillary tube), making the refrigerant piping complicated. Moreover, when the temperature of each hot water storage tank is set to two types, high temperature and low temperature, hot water from the hot water storage tank set to low temperature cannot be supplied to the hot water storage tank set to high temperature and used. This is extremely inconvenient when it is desired to use a large amount of hot water, and the device cannot necessarily be said to be efficient in terms of hot water production and hot water supply.

くの洗浄時間が費される等の種々の無駄が生じていた。Furthermore, for example, a large amount of tap water has traditionally been used to clean toilet bowls. However, since tap water has a relatively low temperature, sufficient cleaning could not be achieved even though it was used in large quantities. Therefore, a lot of tap water is consumed, and various wastes occur, such as a lot of cleaning time.
そこで、ヒートポンプ式給湯装置を利用して、トイレ便

An object of the present invention is to provide a heat pump type air-conditioning/heating water supply device that can supply hot water to a hot water storage tank set at a high temperature and can efficiently supply water and hot water.

A water supply and hot water supply piping system is formed by piping a plurality of hot water storage tanks each containing a built-in refrigerant heating coil in series, and a refrigerant piping system is formed by piping each heating coil of the plurality of hot water storage tanks in parallel to circulate the refrigerant. However, since the circulation of the refrigerant to each heating coil of this refrigerant piping system is appropriately controlled according to the hot water temperature in the plurality of hot water storage tanks and various air conditioning operation commands,
The hot water temperature of multiple hot water storage tanks can be set differently, making it possible to adjust the hot water temperature appropriately depending on the usage status and application of the hot water or the air conditioning operation status.Moreover, it is possible to adjust the hot water temperature in a hot water storage tank set at a low temperature to a high temperature. Hot water can be supplied sequentially to the set hot water storage tank. In addition, hot water can be used for flushing by installing hot water piping to the toilet bowl.

１）をバイパスさせる。First, in step S1, it is determined whether the temperature of hot water in the first hot water storage tank (1) is higher than a set temperature based on a signal from the thermistor (22). If it is low, in step S2,
The first solenoid valve (3) is opened to increase the supply of high temperature refrigerant to the heating coil (9) of the first hot water storage tank (1), and the first solenoid valve (3) for bypassing the first hot water storage tank (1) is opened. Close the No. 2 solenoid valve (4). On the other hand, if the hot water temperature in the first hot water storage tank (1) is higher than the set temperature in step S1, the first solenoid valve (3) is closed in step S3,
At the same time as stopping the supply of refrigerant to the first hot water storage tank (1), the second solenoid valve (4) is released and the first hot water storage tank (
1) is bypassed.

（７）を解放する。Next, in step S4, it is determined whether the temperature of the hot water in the second hot water storage tank (2) is higher than the set temperature based on the signal from the thermistor (23). If the temperature is high, in step S5, the second solenoid valve (4) bypassing the first hot water storage tank (1) is closed, and the second hot water storage tank (2
) is released to enable operation of the first hot water storage tank (1). Furthermore, the toilet backup solenoid valve (7), which will be described later, is closed to end the program. On the other hand, if the water temperature in the second hot water storage tank (2) is lower than the set temperature in step S4, the toilet backup solenoid valve (7) is released in step S6.

を略一定に保つことができる。Here, the reason for opening the toilet backup solenoid valve (7) will be explained. In this embodiment, hot water from the second hot water storage tank (2) is used to clean the toilet bowl (25),
This is because the amount of water is adjusted to suit the cleaning effect depending on the temperature of the water. That is, when the water temperature is low, it is necessary to increase the amount of water for flushing, and the toilet backup solenoid valve (7) is opened to back up the flushing effect. As a result, the cleaning effect of the toilet bowl (25) can be kept substantially constant.

水量で行なわれる。After the toilet backup electromagnetic valve (7) is opened in step S6, it is determined in step S7 whether or not there is a heating operation priority instruction from an air conditioning operation control circuit (not shown). If there is a heating operation priority instruction, the third solenoid valve (5) is released in step S8, the second hot water storage tank (2) is bypassed, and heating and air conditioning operation is prioritized. Then, the program ends. On the other hand, if there is no heating operation priority instruction in step S7, the third
The solenoid valve (5) is closed, refrigerant is supplied to the second hot water storage tank (2), and the program ends. Through the series of operations from step S4 to step S9 described above, the water temperature in the second hot water storage tank (2) gradually approaches the set temperature, and the toilet bowl (25) is flushed with an appropriate amount of water depending on the water temperature.

を促進できる。[Effects of the Invention] As explained above, the heat pump type air conditioning/heating/water supply device of the present invention has a plurality of hot water storage tanks each having a built-in refrigerant heating coil connected in series to form a water supply and hot water supply piping system. Each heating coil of the tank is piped in parallel to form a refrigerant piping system that circulates the refrigerant, and the refrigerant circulation to each heating coil of the refrigerant piping system is controlled by the hot water temperature in the plurality of hot water storage tanks and various air conditioning operations. With a simple configuration that controls according to commands, the hot water temperature of multiple hot water storage tanks can be set differently, and the hot water temperature can be adjusted appropriately depending on the usage status and application of hot water or the air conditioning operation status. Since hot water from a hot water storage tank set at a low temperature can be sequentially supplied to a hot water storage tank set at a high temperature, efficient water and hot water supply can be achieved. In addition, it is possible to promote multifunctionality, such as using hot water to clean the toilet bowl.
