いう問題がある。In the heat pump type hot water floor heating apparatus, as shown in FIGS. 2 (A) and 2 (B), hot water circulates through a floor heating panel having a large heat capacity. It takes time for the water temperature to drop back to the temperature, and it takes time for the return water temperature to rise again when the thermo is turned on next time. Further, in the heat pump type hot water floor heating device, if the operating frequency of the compressor is controlled by PID (proportional / integral / differential) control, the operating frequency becomes too high because the return water temperature after the thermo-on does not rise immediately. Even if the thermostat is turned off, the return water temperature rises without immediately decreasing, and the overshoot of the return water temperature (indicated by A in FIG. 2B) increases. For this reason, there is a problem that the controllability of the temperature of the hot water is poor, and the compressor is repeatedly started and stopped, resulting in poor efficiency.

The hot water heated by the hot water heat exchanger in this way is circulated through the floor heating panel through the hot water heat exchanger by the circulation pump, and the floor heating panel is heated to perform floor heating. Then, the temperature of the hot water flowing through the floor heating panel is detected by a temperature sensor provided on the upstream side or the downstream side of the floor heating panel, and thermo-on (the temperature of the hot water is equal to or lower than a predetermined lower limit temperature) based on the temperature of the hot water. When the compressor is started and operated, the inverter output control unit controls the output of the inverter to operate the compressor at a predetermined low frequency for a predetermined time from the start of the compressor. I do. By doing so, even if the temperature of the hot water does not rise immediately, the operating capacity is not raised within the predetermined time. In addition, the thermostat is not turned off (the temperature of the hot water reaches a predetermined upper limit temperature and stopped), and the compressor does not stop. Therefore, the temperature of the hot water circulating in the floor heating panel is stabilized, the number of times of starting and stopping of the compressor can be reduced, and the efficiency can be improved.

Is a predetermined time t after the thermo-on, as shown in FIG.
During this period, the output of the inverter 15 is controlled so that the compressor 1 operates at the lowest frequency. Then, as shown in FIG. 2 (D), the return water temperature detected by the temperature sensor 20 is:
The temperature difference ΔD between the return water temperature and the target temperature decreases for a while after the thermo-on and increases, but the return water temperature gradually starts to increase with time. At this time, since the driving capacity is not increased during the predetermined time t from the thermo-on, the thermostat is not immediately turned off because the return water temperature gradually rises. In other words, since the return water temperature gradually rises, a large overshoot (shown at A in FIG. 2B) does not occur, and the overshoot in the heat pump hot water floor heating device is as follows.
As shown by B in FIG. 2 (D), it becomes smaller and does not exceed the thermo-off level. After the predetermined time t has elapsed, the control device 14 controls the operating frequency of the compressor 1 by a predetermined control method (for example, PID control). At the above-mentioned predetermined time t, the compressor 1 may be operated at a predetermined low frequency instead of the lowest frequency, or may be operated at a low frequency within a predetermined range.
