  Hereinafter, an embodiment will be described with reference to the drawings.

  As shown in FIG. 1, one end of a refrigerant flow path of a hydrothermal exchanger 3 is connected to a discharge port of a compressor 1 via a four-way valve 2 and the other end of the refrigerant flow path is a decompressor. 4 is connected to one end of the air heat exchangers 5a and 5b through a pipe. The other ends of the air heat exchangers 5 a and 5 b are connected to the suction port of the compressor 1 through the four-way valve 2 and the accumulator 6. These pipe connections constitute a heat pump refrigeration cycle. Outdoor fans 7a and 7b are disposed in the vicinity of the air heat exchangers 5a and 5b. The outdoor fans 7a and 7b suck in outside air and pass the sucked air through the air heat exchangers 5a and 5b.

  During heating, as indicated by an arrow, the gas refrigerant discharged from the compressor 1 flows through the four-way valve 2 to the refrigerant flow path of the water heat exchanger 3. The gas refrigerant that has flowed through the refrigerant flow path is condensed by being deprived of heat by the water flowing through the water flow path of the water heat exchanger 3. The liquid refrigerant flowing out from the refrigerant flow path of the water heat exchanger 3 is decompressed by the expansion valve 4 and flows to the air heat exchangers 5a and 5b. The liquid refrigerant that has flowed to the air heat exchangers 5a and 5b draws heat from the outside air and evaporates. The gas refrigerant flowing out from the air heat exchangers 5 a and 5 b is sucked into the compressor 1 through the four-way valve 2 and the accumulator 6. The refrigerant flow path of the water heat exchanger 3 functions as a condenser, and the air heat exchangers 5a and 5b function as evaporators.

  An outdoor fan (first outdoor fan) 7a and an outdoor fan (second outdoor fan) 7b are disposed in the vicinity of the air heat exchangers 5a and 5b. The outdoor fans 7a and 7b suck in the outside air and pass the sucked air through the air heat exchangers 5a and 5b. An outdoor air temperature sensor 31 is disposed upstream of the suction air passage formed by the outdoor fans 7a and 7b. The outside air temperature sensor 31 detects the temperature To of the outside air sucked by the outdoor fans 7a and 7b.

  A suction port of the circulation pump 12 is connected to a water outlet of the water heat exchanger 3 via a heater 11 serving as an auxiliary heat source, and a discharge port of the circulation pump 12 is connected to a water inlet of the three-way valve 13. And the water inlet of the heat radiating coil 15 in the hot water supply tank 14 is piped to the water outlet 13 a of the three-way valve 13, and the water outlet of the heat radiating coil 15 is piped to the water inlet of the water heat exchanger 3. Further, water inlets of the plurality of heating radiators 21, 22, 23 are respectively connected to the water outlet 13 b of the three-way valve 13, and the water outlets of the heating radiators 21, 22, 23 are water of the water heat exchanger 3. Pipe connected to the inlet. The three-way valve 13 has a water inlet and two water outlets 13a and 13b, and selects either the first flow path from the water inlet to the water outlet 13a or the second flow path from the water inlet to the water outlet 13b. Form.

  A hot water circulation cycle is formed by piping connection from the water heat exchanger 3 to the hot water supply tank 14 and the heating radiators 21, 22, and 23. A hot water temperature sensor 32 is attached to the piping from the hot water supply tank 14 and the heating radiators 21, 22, 23 to the water heat exchanger 3. The hot water temperature sensor 32 detects the temperature Tw of the hot water that flows out of the hot water supply tank 14 and the heating radiators 21, 22, and 23 and returns to the water heat exchanger 3.

  The heater 11 heats the hot water flowing out from the water heat exchanger 3 as necessary during the heating operation. For example, an electric heater or a gas boiler is used. The circulation pump 12 sends the hot water flowing out from the water heat exchanger 3 to the hot water supply tank 14 or the heating radiators 21, 22, 23 and flows out from the hot water supply tank 14 or the heating radiators 21, 22, 23. Hot water is allowed to flow into the water heat exchanger 3. Heating radiators 21, 22, and 23 discharge the heat of the flowing hot water to the air-conditioned space, and selectively use a floor heating panel, a hot air blowing type fan coil, a heat radiation type radiator, or the like. Is possible.

  The hot water supply tank 14 has a built-in heat dissipating coil 15 and a heater (electric heater) 16, and the water flowing from the inlet pipe 17 is warmed by the heat dissipated by the heat dissipating coil 15 and the heat generated by the heater 16 and stored as hot water for hot water supply. The hot water is led to the drain pipe 18. When the tap 18 a at the tip of the water discharge pipe 18 is opened, the hot water in the hot water supply tank 14 flows out through the water discharge pipe 18. A hot water temperature sensor 33 is disposed in the hot water supply tank 14. The hot water temperature sensor 33 detects the temperature Tt of hot water in the hot water supply tank 14.

  The compressor 1, the four-way valve 2, the water heat exchanger 3, the expansion valve 4, the air heat exchangers 5a and 5b, the accumulator 6, the outdoor fans 7a and 7b, and the outdoor air temperature sensor 31 are accommodated in the outdoor unit A. The water heat exchanger 3, the heater 11, the circulation pump 12, and the hot water temperature sensor 32 are accommodated in the hydrothermal exchange unit B.

  The external appearance of the outdoor unit A is shown in FIG. The housing 50 forming the appearance of the outdoor unit A includes two air discharge ports 51a and 51b arranged in the vertical direction on the front surface. The outdoor fan 7a is disposed inside the upper air discharge port 51a, and the outdoor fan 7b is disposed inside the lower air discharge port 51b. And in the housing | casing 50, the said outside temperature sensor 31 is arrange | positioned at the suction air path formed by the outdoor fan 7a.

  A controller (control means) 40 is connected to the outdoor unit A and the hydrothermal exchange unit B. Connected to the controller 40 are a remote control type operation indicator 41 for setting operating conditions, an electromagnetic three-way valve 13, a heater 16 of a hot water supply tank 14, a hot water temperature sensor 33, and the like. In addition, the controller 40 is arrange | positioned in the housing | casing of the hydrothermal exchange unit B, and the operation display part 41 is installed in utilization destinations, such as each supply destination of hot water, and an air-conditioned space.

  The controller 40 has the following functions (1) to (4) as main functions based on the control program stored in the internal memory.

  (1) When the hot water supply operation mode is set by the operation indicator 41, the first flow path of the three-way valve 13 is opened and the second flow path is closed, and hot water between the water heat exchanger 3 and the hot water supply tank 14 is set. First control means for forming a circulation cycle;

  (2) When the heating operation mode is set on the operation indicator 41, the second flow path of the three-way valve 13 is opened and the first flow path is closed, and the water heat exchanger 3 and the heating radiators 21, 22, and 23 are closed. A second control means for forming a hot water circulation cycle between the first and the second.

  (3) In the hot water supply operation mode and the heating operation mode, the operation of the heat pump refrigeration cycle and the operation of the auxiliary heat source (heater 11 or heater 16) are detected by the detection temperature To of the outside air temperature sensor 31 and the detection temperature Tw of the hot water temperature sensor 32. And a third control means for operating the outdoor fans 7a and 7b and the circulation pump 12 before starting the operation of the heat pump refrigeration cycle or before starting the operation of the auxiliary heat source.

  (4) Fourth control means for operating the outdoor fans 7a and 7b when the operation of the heat pump refrigeration cycle is stopped and the auxiliary heat source is operated by the control of the third control means.

  Next, the control executed by the controller 40 will be described with reference to the flowchart of FIG.

[Hot water supply operation mode]
The controller 40 monitors the establishment of the operation start condition according to the operation of the operation indicator 41, the set temperature of the operation indicator 41, the detected temperature Tt of the hot water temperature sensor 33, and the like (step S1). When the operation start condition is satisfied (YES in step S1), the controller 40 turns on the operation of the circulation pump 12 and turns on the operation of the outdoor fans 7a and 7b as a measure before actually starting the operation ( Step S2).

  When the circulation pump 12 is turned on, hot water (or water) flows between the water heat exchanger 3 and the hot water supply tank 14 and the temperature Tw of the flowing hot water is detected by the hot water temperature sensor 32. Since the warm water flows, the stagnation of the warm water in the piping is eliminated, and the warm water temperature Tw can be accurately captured.

  When the outdoor fans 7 a and 7 b are turned on, the outside air is sucked into the outdoor unit A, and the temperature To of the sucked air (outside air) is detected by the outside air temperature sensor 31. Since the outside air circulates, the outside air temperature To can be accurately captured.

  The controller 40 starts the time count t from “0” when the circulation pump 12 is turned on and the outdoor fans 7a and 7b are turned on (step S3). The time count t and the set time t1 (for example, 3 minutes) Are compared (step S4).

  When the time count t reaches the set time t1 (YES in step S4), the controller 40 compares the detected temperature To of the outside air temperature sensor 31 with the set value To3 (step S5).

  The set value To3 is included in the operation control conditions shown in FIG. This operation control condition defines a heat pump region for operating the heat pump refrigeration cycle and an auxiliary heat source region for operating the heater 11 as an auxiliary heat source with respect to the outside air temperature To and the hot water temperature Tw. The heat pump area corresponds to the use range for protecting the compressor. Looking at the outside air temperature To, a temperature lower than the set value To3 is defined as a heat pump region, and a value equal to or greater than the set value To3 is defined as an auxiliary heat source region. Looking at the hot water temperature Tw, a temperature less than a variable set value that changes in the range of set values Tw2 to Tw4 according to the outside air temperature To is defined as a heat pump region, and a variable set value or more is defined as an auxiliary heat source region.

  When the detected temperature To of the outside air temperature sensor 31 is less than the set value To3 (YES in Step S5), the controller 40 determines whether or not the detected temperature Tw of the hot water temperature sensor 32 exists in the heat pump region (Step S6).

  When the detected temperature Tw of the hot water temperature sensor 32 exists in the heat pump region (YES in step S6), the controller 40 performs the operation of the heat pump refrigeration cycle, so-called heat pump operation (step S7).

  That is, the controller 40 turns on the compressor 1 and turns on the outdoor fans 7a and 7b as the heat pump operation. Thereby, the water heat exchanger 3 functions as a condenser. Further, the controller 40 turns on the circulation pump 12. The heaters 11 and 15 are not operated. Thereby, the hot water heated by the water heat exchanger 3 flows into the hot water supply tank 14. Hot water in the hot water supply tank 14 is warmed by the pumping heat of the heat pump refrigeration cycle.

  When the detected temperature To of the outside air temperature sensor 31 is equal to or higher than the set value To3 (NO in step S5), the controller 40 performs an auxiliary heat source operation using the heater 16 in the hot water supply tank 14 (step S8). In addition, even if the detected temperature To of the outside air temperature sensor 31 is lower than the set value To3 (YES in Step S5), the controller when the detected temperature Tw of the hot water temperature sensor 32 is out of the heat pump area (NO in Step S6). 40 performs an auxiliary heat source operation using the heater 16 (step S8).

  That is, the controller 40 operates the heater 16 and turns on the circulation pump 12 as an auxiliary heat source operation. The heater 11 is not operated. Therefore, the hot water in the hot water supply tank 14 is warmed by the heat generated by the heater 16.

  During the auxiliary heat source operation using the heater 16, the controller 40 turns on the outdoor fans 7a and 7b. Since the outdoor air flows when the outdoor fans 7a and 7b are turned on, accurate detection of the outdoor air temperature To by the outdoor air temperature sensor 31 can be continued.

  With the execution of the heat pump operation or the auxiliary heat source operation, the controller 40 monitors the establishment of the operation stop condition according to the operation of the operation indicator 41, the set temperature of the operation indicator 41, the detected temperature Tt of the hot water temperature sensor 33, and the like. (Step S9).

  If the operation stop condition is not satisfied (NO in step S9), the controller 40 returns to the determination in step S5. When the operation stop condition is satisfied (YES in step S9), the heat pump operation or the auxiliary heat source operation is stopped (step S10).

[Heating operation mode]
The controller 40 monitors the establishment of the operation start condition according to the operation of the operation indicator 41, the set temperature of the operation indicator 41, the atmospheric temperature (room temperature) of the air-conditioned space (step S1). When the operation start condition is satisfied (YES in step S1), the controller 40 turns on the operation of the circulation pump 12 and turns on the operation of the outdoor fans 7a and 7b as a measure before actually starting the operation ( Step S2).

  When the circulation pump 12 is turned on, hot water (or water) flows between the water heat exchanger 3 and the heating radiators 21, 22, and 23, and the temperature Tw of the flowing hot water is detected by the hot water temperature sensor 32. Is done. Since the warm water flows, the stagnation of the warm water in the piping is eliminated, and the warm water temperature Tw can be accurately captured.

  When the outdoor fans 7 a and 7 b are turned on, the outside air is sucked into the outdoor unit A, and the temperature To of the sucked air (outside air) is detected by the outside air temperature sensor 31. Since the outside air circulates, the outside air temperature To can be accurately captured.

  The controller 40 starts the time count t from “0” when the circulation pump 12 is turned on and the outdoor fans 7a and 7b are turned on (step S3). The time count t and the set time t1 (for example, 3 minutes) Are compared (step S4).

  When the time count t reaches the set time t1 (YES in step S4), the controller 40 compares the detected temperature To of the outside air temperature sensor 31 with the set value To3 (step S5).

  When the detected temperature To of the outside air temperature sensor 31 is less than the set value To3 (YES in Step S5), the controller 40 determines whether or not the detected temperature Tw of the hot water temperature sensor 32 exists in the heat pump region (Step S6).

  When the detected temperature Tw of the hot water temperature sensor 32 exists in the heat pump region (YES in step S6), the controller 40 executes the heat pump operation (step S7).

  That is, the controller 40 turns on the compressor 1 and turns on the outdoor fans 7a and 7b as the heat pump operation. Thereby, the water heat exchanger 3 functions as a condenser. Further, the controller 40 turns on the circulation pump 12. The heaters 11 and 15 are not operated. Thereby, the warm water warmed by the water heat exchanger 3 flows to the heating radiators 21, 22, and 23. The air-conditioned space with the radiators 21, 22 and 23 for heating is heated by the pumping heat of the heat pump refrigeration cycle.

  When the detected temperature To of the outside air temperature sensor 31 is equal to or higher than the set value To3 (NO in step S5), the controller 40 performs an auxiliary heat source operation using the heater 11 (step S8). In addition, even if the detected temperature To of the outside air temperature sensor 31 is lower than the set value To3 (YES in Step S5), the controller when the detected temperature Tw of the hot water temperature sensor 32 is out of the heat pump area (NO in Step S6). 40 performs an auxiliary heat source operation using the heater 11 (step S8).

  That is, the controller 40 operates the heater 11 and turns on the circulation pump 12 as the auxiliary heat source operation. Thereby, water circulates between the water heat exchanger 3 and the radiators 21, 22, and 23 for heating, and the circulating water is warmed by the heat generated by the heater 11. The compressor 1 is not operated. The heater 16 is not operated. Therefore, the air-conditioned space with the radiators 21, 22, and 23 for heating is heated by the heat generated by the heater 11.

  During the auxiliary heat source operation using the heater 11, the controller 40 turns on the outdoor fans 7a and 7b. Since the outdoor air flows when the outdoor fans 7a and 7b are turned on, accurate detection of the outdoor air temperature To by the outdoor air temperature sensor 31 can be continued.

  With the execution of the heat pump operation or the auxiliary heat source operation, the controller 40 establishes the operation stop condition according to the operation of the operation indicator 41, the set temperature of the operation indicator 41, the atmospheric temperature (indoor temperature) of the air-conditioned space, and the like. Monitor (step S9).

  If the operation stop condition is not satisfied (NO in step S9), the controller 40 returns to the determination in step S5. When the operation stop condition is satisfied (YES in step S9), the heat pump operation or the auxiliary heat source operation is stopped (step S10).

  As described above, before the heat pump operation and the auxiliary heat source operation are started, the outdoor fans 7a and 7b are turned on in advance to distribute the outside air, so that the casing 50 of the outdoor unit A is exposed to direct sunlight. Or even if the circumference | surroundings of the housing | casing 50 are enclosed by the wall etc., the outside temperature To can be caught exactly.

  For example, in the operation control conditions of FIG. 4, when the outdoor fans 7a and 7b are turned off, the temperature detected by the outside air temperature sensor 31 is affected by direct sunlight and becomes a value Tox higher than the set value To3, and the efficiency of using the heater 11 A poor auxiliary heat source operation is executed. On the other hand, when the outdoor fans 7a and 7b are turned on in advance, the detected temperature of the outdoor air temperature sensor 31 becomes a value (proper value) Toa lower than the set value To3 regardless of the influence of direct sunlight. Therefore, appropriate operation control of the heat pump refrigeration cycle becomes possible, and the operation rate of the heat pump refrigeration cycle is expanded. Energy saving performance is improved.

  In addition, since the circulating pump 12 is turned on and the hot water circulation cycle is allowed to flow before the heat pump operation or the auxiliary heat source operation is started, stagnation of hot water in the piping is eliminated, and the hot water temperature Tw can be accurately captured. Can do.

  Since both the outside air temperature To and the hot water temperature Tw can be accurately captured, the time required for determining the operation region can be shortened. That is, the responsiveness of the operation control is improved, and useless waiting time can be reduced. Also in this respect, appropriate operation control of the heat pump refrigeration cycle is possible.

  Furthermore, in the case of an auxiliary heat source operation using a heater, the operation of the outdoor fans 7a and 7b is unnecessary if only considering obtaining a heat generation amount. In contrast, in the present embodiment, since the outdoor fans 7a and 7b are operated on during the auxiliary heat source operation, the outside air temperature To can be accurately captured even during the auxiliary heat source operation. When the casing 50 of the outdoor unit A is set in a place where there is no wind or no wind, even if the actual outside air temperature To moves from the auxiliary heat source area to the heat pump area, the outside air temperature sensor 31 is used. Takes time to detect. Such a detection delay can be eliminated by turning on the outdoor fans 7a and 7b.

  Further, the heat pump region in the operation control condition is determined in consideration of the capacity and performance of the compressor 1. For this reason, if the compressor 1 is operated outside the original heat pump region, the compressor 1 is overloaded, and the mechanical life and reliability of the compressor 1 are adversely affected. On the other hand, in the present embodiment, since both the outside air temperature To and the hot water temperature Tw are accurately captured, such a problem can be prevented.

[Modification of Embodiment]
Note that the following (4x) fourth control means may be employed instead of the (4) fourth control means of the controller 40.

  (4x) Intermittent operation so-called interval operation in which the outdoor fans 7a and 7b are turned on for each predetermined time when the operation of the heat pump refrigeration cycle is stopped and the auxiliary heat source is operated by the control of the third control means. 4th control means to perform.

  Thus, by performing the interval operation of the outdoor fans 7a and 7b, it is possible to suppress power consumption as much as possible while accurately capturing the outside air temperature To. Energy saving performance is improved.

  On the other hand, instead of the third control means (3) and the fourth control means (4) of the controller 40, the following (3y) third control means and (4y) fourth control means are adopted. May be.

  (3y) In the hot water supply operation mode and the heating operation mode, the operation of the heat pump refrigeration cycle and the operation of the auxiliary heat source (heater 11 or heater 16) are detected by the detection temperature To of the outside air temperature sensor 31 and the detection temperature Tw of the hot water temperature sensor 32. And a third control means for operating the outdoor fan 7a and the circulation pump 12 to stop the outdoor fan 7b before starting the operation of the heat pump refrigeration cycle or before starting the operation of the auxiliary heat source.

  (4y) Fourth control means for operating the outdoor fan 7a and stopping the outdoor fan 7b when the operation of the heat pump refrigeration cycle is stopped and the auxiliary heat source is operated by the control of the third control means.

  In this way, by operating only the outdoor fan 7a on the side close to the arrangement position of the outdoor air temperature sensor 31 and stopping the outdoor fan 7b, the power consumption required for the outdoor fan operation can be suppressed while accurately capturing the outdoor air temperature To. Can do. Energy saving performance is improved.

  In addition, the said embodiment and each modification are shown as an example, and are not intending limiting the range of invention. The novel embodiments and modifications can be implemented in various other forms, and various omissions, rewrites, and changes can be made without departing from the spirit of the invention.
