Next, the water level of the brine as the heat medium of the heat storage cold storage tank 7 is measured, and there is a water level above a certain level.
ES if moved to the next hot water treatment for the control process side, constant following measures the temperature t ₂ of if NO brine level, YES temperature t ₂ of the brine is at a predetermined temperature or lower (e.g., t ₂ <-3 ° C.) If so, the process proceeds to the next hot water supply control process. If the temperature t _{2 of the} brine is equal to or higher than the predetermined temperature and NO is determined, the process proceeds to the cold storage control process. After determining that the cold storage has reached a predetermined state, the temperature t ₄ of the hot water in the hot water storage tank 9 is measured,
The temperature of the hot water in the hot water storage tank 9 is equal to or higher than a predetermined temperature (for example, t ₄ > 45

If NO in automatic control or NO in the bath, the process returns. If YES automatically, the temperature of the hot water in the bath 30 t ₆
At the same time as measuring the water level of the bath 30,
₆ is above a certain temperature (eg t ₆ > 41 ° C) or bath 30
It is determined whether the water level is equal to or higher than the predetermined water level, and if the water temperature is equal to or higher than the predetermined temperature and is equal to or higher than the predetermined water level, YES is returned. If the hot water of the bath 30 is below a predetermined temperature or below a predetermined water level and is NO, it is judged whether the water level of the bath 30 is within an allowable range (for example, within -5 cm from the predetermined water level), and the water level of the bath 30 is If the water level is lower than the allowable range, water is supplied from the hot water storage tank 9. If the water level of the bath 30 is within the allowable range, it is determined that the temperature of the hot water of the bath 30 is low, and the circulation pump P ₄ is turned on and the heater 40 is turned on to reheat the hot water of the bath 30 to heat the hot water. Raise. In this way, when the water level of the hot water of the bath 30 reaches a predetermined height and the temperature of the hot water of the bath 30 becomes a predetermined temperature or higher, the process returns.

The above control is repeated again.

Next, the control of the winter operation will be described. Figure 1
Reference numeral 3 shows a main routine for driving in winter. When the winter operation is started, the heater 40 is controlled to be turned on or off in the heater processing control process. Then, the control bath in the bath processing control step, then it is determined whether the heating load is not there in the off circulation pump P _1, the circulation pump P ₁ is transferred to YES if the heating processing control step on, If NO, the process moves to the next control process side for heat storage treatment. Then, the temperature t ₂ of the brine as the heat medium of the heat storage cool storage tank 7 is measured, and if the temperature t _{2 of} the brine is equal to or higher than a predetermined temperature (for example, t ₂ > 55 ° C.), the process goes to the next hot water supply control process. If the temperature t _{2 of the} brine is equal to or lower than the predetermined temperature and NO, the process proceeds to the control process for heat storage treatment. After determining that the heat has been stored up to a predetermined state, the temperature t ₄ of the hot water in the hot water storage tank 9 is measured, and if the temperature of the hot water in the hot water storage tank 9 is equal to or higher than a predetermined temperature (for example, t ₄ > 45 ° C.), YES.

It is determined whether the water level is equal to or higher than the predetermined water level, and if the water temperature is equal to or higher than the predetermined temperature and is equal to or higher than the predetermined water level, YES is returned. If the hot water of the bath 30 is below a predetermined temperature or below a predetermined water level and is NO, it is judged whether the water level of the bath 30 is within an allowable range (for example, within -5 cm from the predetermined water level), and the water level of the bath 30 is If the water level is lower than the allowable range, water is supplied from the hot water storage tank 9. When the water level of the bath 30 is within the allowable range, it is determined that the temperature of the hot water of the bath 30 is low, and the circulation pump P ₄ is turned on and the heater 40 is turned on to reheat the hot water of the bath 30 to change the temperature of the hot water. increase.

The circulation pump P3 and the heater 40 are turned on and the process returns. If the answer is NO, not the large family, then it is determined whether the family is small and it is night. Here, if it is determined that the small family is not at night, the result is NO, the heater 40 is turned off, and the process returns. If the family is small and it is night, it becomes YES, and then it is determined whether the heat pump 2 is in the hot water storage operation in the M3 mode. If the hot water storage operation is in M3 mode, the answer is YES.
The heater 40 is turned off and the process returns. If NO in the M3 mode and not in the hot water storage operation, the circulation pump P ₃ and the heater 40 are turned on and the process returns.

When the bath processing is finished, it is determined whether the circulation pump P ₁ is on to determine whether or not there is a heating load as in the main routine of FIG. 13. When there is no heating load and the circulation pump P ₁ is off, the result is NO, and the process advances to the next heat storage control process. If there is a heating load and the circulation pump P ₁ is on and YES, the process proceeds to the heating process control process.

When the bath process control process is completed, the heat pump 1 is driven to heat in the M4 mode, and then the heater process control process starts. This heater process is also shown in FIG.
When the control of the heater processing is completed, the process is moved to the heating management control process. The heating management control process is performed by a subroutine as shown in FIG. In the heating management process, it is determined whether the temperature t ₉ of the heating medium of the heating load is equal to or higher than the upper limit temperature of the predetermined temperature range (for example, t ₉ > 42 ° C.). The valve V ₆ is switched so as to flow to the A side, and is returned via the bypass line 22 to return. If the temperature t ₉ of the heating medium of the heating load is equal to or lower than the upper limit temperature and is NO, then whether the temperature t ₉ of the heating medium of the heating load is equal to or lower than the lower limit temperature of the predetermined temperature range (for example, t ₉ <40 ° C.). If the temperature is equal to or higher than the lower limit temperature, the flow returns to NO, and if the temperature is equal to or lower than the lower limit temperature, YES, the switching valve V ₆ is switched to the B side to flow to the load heat exchanger 6, and the load heat medium path 5 is passed.
