[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention provides a heat pump device capable of executing a heating operation for heating hot water in a hot water storage tank and an air conditioning operation for air-conditioning a space to be air-conditioned, and an operation control means for controlling operation of the heat pump device. The present invention relates to a hot water supply heat source device.
[0002]
[Prior art]
The above hot water supply type hot water supply heat source device is used for ordinary households, and the operation control unit heats or cools a space to be air-conditioned such as a living room by performing a heating operation or a cooling operation of the heat pump device according to an air-conditioning request. At the same time, hot water is stored in a hot water storage tank by heating the heat pump device, and the stored hot water is supplied to a hot water tap or a bathtub.
[0003]
In the conventional hot water supply type hot water supply heat source device, when the operation control unit is performing the air conditioning operation in response to the air conditioning request, when the air conditioning target space is in the target air conditioning state, the heat pump device is continuously operated to perform the heating operation. Air-conditioning of the space to be air-conditioned and storage of hot water in a hot-water storage tank are performed while improving efficiency.
[0004]
In addition, the operation control unit may temporarily stop the operation of the heat pump device when the space to be air-conditioned is in the target air-conditioning state during the air-conditioning operation, and the air-conditioning space may deviate from the target air-conditioning state. Accordingly, the heat pump device can be intermittently operated so as to restart the operation of the heat pump device.
However, in such a case, the operation start and the operation stop of the heat pump device are repeated, and the heat pump device is operated in a state including the low-efficiency initial operation start many times, resulting in low efficiency. It becomes.
Therefore, when the operation control unit performs the air-conditioning operation, the heat pump device is continuously operated to perform the heating operation, so that the air-conditioning target space is air-conditioned and the hot water is stored in the hot-water storage tank while improving efficiency. (For example, see Patent Document 1).

[0006]
[Problems to be solved by the invention]
However, in the above-described conventional hot water supply type hot water supply heat source device, when the operation control unit is performing the air-conditioning operation, the heating operation is simply performed when the space to be air-conditioned is in the target air-conditioning state. Even during a time when it is predicted that hot water in the tank will not be supplied, as long as the air-conditioned space is in the target air-conditioning state, the heating operation is performed and hot water is stored in the hot water storage tank. .
[0007]
For example, a description will be given of an example of a household having a usage pattern in which the hot water in the hot water storage tank is supplied from 19 o'clock to 21 o'clock and the hot water in the hot water storage tank is hardly supplied at midnight. In addition, in this home, it can be predicted that the hot water in the hot water storage tank will not be supplied after that at the time before the midnight time.
However, the operation control means performs the heating operation to store hot water in the hot water storage tank when the air-conditioned space is in the target air-conditioning state during the air-conditioning operation before the midnight time zone. become.
[0008]
As described above, even when it is predicted that hot water in the hot water storage tank will not be supplied thereafter, the heating operation is performed to store hot water in the hot water storage tank. Most of the hot and cold water is radiated without being used for hot water supply, resulting in energy loss.
[0009]
Further, in practice, even though most of the hot water stored in the hot water storage tank is not used for hot water supply, when the heating operation is performed, the number of operations of the members for performing the heating operation increases by that much. Therefore, a high durability performance is required for a member for performing the heating operation, which may increase the cost.
[0010]
The present invention has been focused on this point, and its purpose is to perform air conditioning of a space to be air-conditioned and hot water storage in a hot water storage tank while improving efficiency and energy saving and cost reduction. An object of the present invention is to provide a hot water supply heat source device capable of storing hot water.
[0011]
[Means for Solving the Problems]
In order to achieve this object, according to the first aspect of the present invention, a heat pump device capable of executing a heating operation for heating hot water in a hot water storage tank and an air conditioning operation for air conditioning a space to be air-conditioned, and the heat pump device Operation control means for controlling the operation of the hot water storage hot water supply heat source device provided with
Hot water supply time zone setting means for setting a hot water supply time zone predicted to supply hot water in the hot water storage tank,
Air conditioning operation time zone setting means for setting an air conditioning operation time zone in which the heat pump device is predicted to perform air conditioning operation is provided,
The operation control means controls the hot water supply time zone by the heating operation based on the hot water supply time zone setting information by the hot water supply time zone setting means and the air conditioning operation time zone setting information by the air conditioning operation time zone setting means. Determine the heating operation start time for setting the hot water storage amount in the hot water storage tank to the target hot water storage amount at the start time within the air conditioning operation time zone,
In the heating operation time period from the heating operation start time to the start time of the hot water supply time period, the operation of the heat pump device is performed so that the heating operation is performed when the air conditioning operation is being performed by an air conditioning request. It is configured to control.
[0012]
That is, the hot water supply time zone setting means can automatically or artificially set the hot water supply time zone in which it is predicted that hot water in the hot water storage tank will be supplied in accordance with the usage pattern at each home. .
Further, the air conditioning time zone setting means can automatically or artificially set the air conditioning operation time zone in which the air conditioning operation of the heat pump device is predicted according to the usage pattern in each home.
[0013]
The operation control means obtains a heating operation start time within the air conditioning operation time zone based on the hot water supply time zone setting information and the air conditioning operation time zone setting information, and determines the start time of the hot water supply time zone from the heating operation start time. Up to the heating operation time period, it is predicted that the heat pump device will perform the air conditioning operation, and the time period in which the heating operation can be performed when performing the air conditioning operation so as to continuously operate the heat pump device is predicted. Then, it is predicted that hot water in the hot water storage tank will be supplied thereafter, and the time zone in which the heating operation should be performed in preparation for the hot water supply can be set as the heating operation time zone.
[0014]
By the way, the time zone moves back and forth depending on the usage pattern of each household, but generally, (a) in FIG. 4 showing the actual hot water supply situation in which hot water in the hot water storage tank is actually stored, and air conditioning. As shown in (b) of FIG. 4 showing the actual air-conditioning operation state in which the operation was actually performed, the time period during which hot water in the hot water storage tank can be predicted to be supplied and the time period during which air-conditioning operation can be predicted are determined. Will exist.
Then, before the time zone in which it is possible to predict the hot water supply in the hot water storage tank, there is a time zone in which the heating operation should be performed in preparation for the hot water supply, and it is predicted that the air conditioning operation is to be performed in the time zone. The time zone in which the time zone overlaps can be set as the heating operation time zone, and the heating operation time zone is set according to the usage pattern of each home.
[0015]
Then, in the heating operation time zone, the operation control means controls the operation of the heat pump device so that the heating operation is performed when the air conditioning operation is performed according to the air conditioning request, and thereafter, the hot water in the hot water storage tank is controlled. When it is predicted that hot water will be supplied, the heating operation can be performed during the air-conditioning operation.
In addition, in a time zone other than the heating operation time zone, the operation control unit controls the operation of the heat pump device so as not to perform the heating operation even if the air conditioning operation is being performed by the air conditioning request, and thereafter, When it is not predicted that hot water in the hot water storage tank will be supplied, the heating operation can be prevented from being performed even during the air-conditioning operation.
[0016]
Therefore, when it is predicted that hot water in the hot water storage tank will be subsequently supplied, the operation control means performs the heating operation when performing the air conditioning operation, thereby continuously operating the heat pump device, thereby controlling the air conditioning of the air conditioning target space. And hot water can be stored in the hot water storage tank.
In addition, when it is not predicted that hot water in the hot water storage tank is to be supplied, the operation control means can prevent the heating operation from being performed, thereby suppressing wasteful storage of hot water in the hot water storage tank.
[0017]
From the above, it is possible to air-condition the space to be air-conditioned and store hot water in the hot-water storage tank while continuously operating the heat pump device, and it is possible to suppress wasteful storage of hot water in the hot-water storage tank. The present invention has been able to provide a hot water supply type hot water supply heat source device capable of performing air conditioning of a space to be air-conditioned and storing hot water in a hot water storage tank while improving energy consumption and reducing costs.
[0018]
According to the invention described in claim 2, the hot water supply time zone setting means is configured to set the hot water supply time zone based on an actual hot water supply situation in which hot water in the hot water storage tank is actually supplied. ing.
[0019]
In other words, the hot water supply time zone setting means can set the hot water supply time zone corresponding to the time zone in which the hot water in the hot water storage tank is actually supplied even when the time zone for supplying hot water in the hot water storage tank differs according to each household. Therefore, the operation control means is capable of predicting hot water supply in the hot water storage tank while suppressing wasteful storage of hot water in the hot water storage tank in a state corresponding to the usage pattern in each household. In this case, hot water can be stored in the hot water storage tank.
Therefore, the user only needs to actually supply the hot water in the hot water storage tank, and while suppressing wasteful storage of the hot water in the hot water storage tank, the hot water is stored in the hot water storage tank during the time period when the hot water is actually supplied. The hot and cold water can be used for hot water supply, and the usability of the user can be improved.
[0020]
According to the invention described in claim 3, the air-conditioning operation time zone setting means is configured to perform the air-conditioning operation based on an actual air-conditioning operation state in which the heat pump device is actually operated in the air conditioning based on the air-conditioning request. It is configured to set a time zone.
[0021]
In other words, the air-conditioning operation time zone setting means can set the air-conditioning operation time zone corresponding to the actual air-conditioning operation time zone even when the air-conditioning operation time zone differs for each home. The control means can perform the heating operation while performing the air-conditioning operation in a state corresponding to the usage pattern in each home.
Therefore, the operation control means can perform the heating operation during the air-conditioning operation during the time period when the user actually performs the air-conditioning operation, and according to the usage pattern at each home, The heat pump device can be operated efficiently, and the efficiency can be effectively improved.
[0022]
According to the invention described in claim 4, the operation control means is configured to obtain the target hot water storage amount based on an actual hot water supply amount in which hot water in the hot water storage tank is actually supplied in the hot water supply time period. Have been.
[0023]
That is, the operation control means causes the heat pump device to perform a heating operation such that the user stores the amount of hot water in the hot water storage tank in the hot water storage tank at the start time of the hot water supply time zone corresponding to the actual hot water supply amount. Therefore, only the amount that can be predicted to be used by the user can be stored in the hot water storage tank at the start time of the hot water supply time zone.
Therefore, it is possible to prevent excess hot water from being stored in the hot water storage tank while preventing hot water that is not stored in the hot water storage tank by an amount sufficient for the user to use, thereby deteriorating the usability of the user. Without this, energy loss can be accurately suppressed.
[0024]
According to the invention as set forth in claim 5, the operation control means is based on the hot water supply time zone setting information by the hot water supply time zone setting means and the air conditioning operation time zone setting information by the air conditioning operation time zone setting means. A post-processing heating operation time zone is set within the air-conditioning operation time zone after the heating operation time zone, and in the processing heating operation time zone, the air-conditioning operation is performed in response to an air conditioning request. The operation of the heat pump device is controlled such that the heating operation is performed to store the target amount of hot water for post-processing in the hot water storage tank when the heat treatment is being performed.
[0025]
In other words, it is expected that hot water stored in the hot water storage tank will be mostly used during the hot water supply time zone. It is expected that almost no hot water is stored.
Therefore, the operation control unit predicts that the air conditioning operation of the heat pump device will be performed by setting the post-processing heating operation time period within the air conditioning operation time period after the heating operation time period. It is predicted that the heating operation can be performed when the air conditioning operation is performed by continuously operating the air conditioner, and that hot water usable for hot water supply is hardly stored in the hot water storage tank. The time period during which the heating operation should be performed in preparation for the subsequent hot water supply can be set as the post-processing heating operation time period.
[0026]
The operation control means is configured to perform a heating operation during the time period for the post-processing heating operation such that the heating operation is performed to store the target amount of hot water for post-processing in the hot water storage tank during the air conditioning operation. By controlling the operation of the device, even after most of the hot water stored in the hot water storage tank is used for hot water supply, air conditioning of the space to be air-conditioned and hot water storage in the hot water storage tank are performed while the heat pump device is continuously operated. You can do it.
Therefore, it is possible to further improve the efficiency while appropriately responding to the demand for hot water supply according to the usage pattern at each home.

Hereinafter, the hot water storage operation will be described. First, conditions for performing the hot water storage operation will be described, and then the operation of the hot water storage operation will be described.
The conditions for performing the hot water storage operation will be described. The hot water storage unit control unit C includes a hot water supply time zone setting unit C1 that sets a hot water supply time zone in which hot water in the hot water storage tank 1 is predicted to be supplied. Air-conditioning operation time zone setting means C2 for setting an air-conditioning operation time zone in which the air conditioning operation of the engine heat pump type cooling / heating device B is predicted.
Then, hot water storage unit controller C obtains the heating operation time zone based on the hot water supply time zone setting information by hot water supply time zone setting means C1 and the air conditioning operation time zone setting information by air conditioning operation time zone setting means C2. In the heating operation time period, the heat pump operation control unit D performs the heating operation time period calculation process so that the heat pump operation control unit D performs the hot water storage operation when the air conditioning operation of the heating operation or the cooling operation is performed. , And is configured to control the operation of the engine heat pump type cooling / heating device B.
That is, in the heating operation time zone, the hot water storage unit control unit C determines whether or not the air conditioning operation is being performed based on the control signal from the heat pump operation control unit D, and performs the hot water storage operation when the air conditioning operation is being performed. When the air conditioning operation is not being performed, the hot water storage operation is not performed.
[0059]
Describing the heating operation time zone calculation processing, the hot water supply time zone setting means C1 is configured to set the hot water supply time zone based on the actual hot water supply situation in which hot water in the hot water storage tank 1 is actually supplied. The air-conditioning operation time zone setting means C2 is configured to set the air-conditioning operation time zone based on the actual air-conditioning operation state in which the engine heat pump cooling / heating device B is actually air-conditioned based on the air-conditioning request. I have.
The hot water storage unit controller C is configured to obtain a target hot water storage amount based on the actual hot water supply amount of hot water in the hot water storage tank 1 during the hot water supply time period.
[0060]
Then, the hot water storage unit controller C performs the hot water supply time by the hot water storage operation based on the hot water supply time zone setting information by the hot water supply time zone setting means C1 and the air conditioning operation time zone setting information by the air conditioning operation time zone setting means C2. A heating operation start time for setting the hot water storage amount in the hot water storage tank 1 to the target hot water storage amount at the start time of the zone is determined in the air conditioning operation time zone, and heating is performed from the heating operation start time to the start time of the hot water supply time zone. It is configured to be obtained as a driving time zone.
[0061]
On the basis of (a) of FIG. 4 which is data indicating the actual hot water supply situation in one day and (b) of FIG. 4 which is data indicating the actual air conditioning operation situation in one day, the heating operation time zone arithmetic processing is performed. More specifically, the hot water supply time zone setting means C1 sets one hour as a unit time zone based on the actual hot water supply condition in which the hot water in the hot water storage tank 1 is actually supplied as shown in FIG. The energy amount (kW · h) as the actual hot water supply amount per unit time zone in one day is counted.
Then, for example, when the data as shown in FIG. 4A is obtained, the hot water supply time zone setting means C1 concentrates the time period during which the hot water in the hot water storage tank 1 is actually supplied. 18:00 to 24:00 is set as a hot water supply time zone for the next day.
[0062]
The air-conditioning operation time zone setting means C2 sets one hour as a unit time zone as shown in FIG. 4B based on the actual air-conditioning operation status in which the engine heat pump cooling / heating device B is actually air-conditioned. For each of the unit time periods in one day, whether or not the air-conditioning operation has been performed by the control signal from the heat pump operation control unit D is counted.
Then, for example, when the data as shown in FIG. 4B is obtained, the air-conditioning operation time zone setting means C2 sets the time during which the engine heat pump type cooling / heating device B is actually operated in air-conditioning. The time period from 14:00 to 24:00 when the bands are concentrated is set as the air conditioning operation time period of the next day.
[0063]
When the hot water supply time period and the air conditioning operation time period of the next day are set in this way, the hot water storage unit control unit C uses the data shown in FIG. It takes about 2 hours to set the target hot water storage amount to "full" and to make the hot water storage amount in the hot water storage tank 1 "full" as the target hot water storage amount by the hot water storage operation because the amount used for the hot water storage is large. From 16:00, the heating operation start time is set, and as shown in (c) of FIG. 4, the period from 16:00 which is the heating operation start time to 18:00 which is the start time of the hot water supply time period is set as the heating operation time period. I do.
[0064]
The hot water storage unit control unit C includes, in addition to the above-described heating operation time zone, hot water supply time zone setting information by the hot water supply time zone setting unit C1 and air conditioning operation time zone setting information by the air conditioning operation time zone setting unit C2. Based on the above, a post-processing heating operation time zone is set within the air-conditioning operation time zone after the heating operation time zone, and then in the processing heating operation time zone, the air-conditioning operation is performed according to the air-conditioning request. The operation of the engine heat pump type cooling / heating device B is controlled so that the hot water storage operation is performed to store the target amount of hot water for post-processing in the hot water storage tank 1 when the hot water storage is in operation.
[0065]
More specifically, the hot water storage unit controller C sets the heating operation time period from 16:00 to 18:00 and the air conditioning from 14:00 to 24:00 based on the data shown in (a) and (b) of FIG. Since the operation time period is set, the post-processing heating operation time period is set between 18:00 and 24:00.
Then, it can be predicted from the data shown in FIG. 4A that a large amount of hot water in the hot water storage tank 1 will be supplied at 20:00 and 21:00, as shown in FIG. 4C. Then, the subsequent 22:00 hours are set as a time zone for the heating operation for post-processing.
[0066]
In addition, the hot water storage unit control unit C determines whether or not the air conditioning operation is being performed based on the control signal from the heat pump operation control unit D at the time of 22:00, which is the time period for the post-processing heating operation, and performs the air conditioning operation. When the hot-water storage operation is being performed, the hot-water storage operation is performed so that the hot-water storage amount in the hot-water storage tank 1 becomes “small”, for example, and the hot-water storage operation is not performed when the air conditioning operation is not performed. I have to.
[0067]
In this way, the hot water storage unit control unit C is predicted to perform the air conditioning operation of the engine heat pump cooling and heating device B, and can perform the hot water storage operation when performing the air conditioning operation by continuously operating the engine heat pump cooling and heating device B. Is predicted, and it is predicted that hot water in the hot water storage tank 1 will be supplied thereafter. The time period during which the hot water storage operation is to be performed in preparation for the hot water supply is defined as a heating operation time period and a subsequent time period. It can be obtained as the heating operation time zone for processing.
Then, in the heating operation time period and the post-processing heating operation time period, the hot water storage unit control unit C performs the hot water storage operation while performing the air conditioning operation in response to the air conditioning request, and continuously operates the engine heat pump cooling and heating device B. It is possible to air-condition the space to be air-conditioned and store hot water in the hot-water storage tank 1 while operating, and it is possible to suppress wasteful storage of hot water in the hot-water storage tank 1, thereby improving efficiency and saving energy. It is possible to achieve cost reduction and cost reduction.
[0068]
Incidentally, when there is a command to perform the hot water storage operation from the hot water storage remote control R2 by manual operation by the user, the hot water storage unit control unit C causes the hot water storage amount in the hot water storage tank 1 to become the hot water storage amount set by the hot water storage remote control R. It is configured so that hot water storage operation can be performed.
[0069]

[0070]
When the heating operation is being performed, the heat pump operation control unit D sets the HP heating electronic expansion valve 74 a to the open state and performs the heat pump heating unit through the refrigerant pipe 73 because the heating operation is performed as described above. When the high-pressure refrigerant is supplied to the cooling water passage 33 and the cooling water flowing through the cooling water passage 85 has a temperature equal to or higher than the set temperature for heating, the exhaust heat switching mechanism 86 is switched to the heating state, and the cooling water is heated by the engine exhaust heat utilizing heating unit 34 The operation of the cooling water circulating means L is controlled so as to supply the cooling water.

In this manner, when the heating operation is being performed, the hot and cold water taken out from the bottom of the hot water storage tank 1 is heated by the heat pump heating unit 33 and the engine exhaust heat utilization heating unit 34, and the heated hot and cold water is heated. Is returned to the upper part of the hot water storage tank 1 to store the hot water in the hot water storage tank 1.
In the heating operation time period, the above-described operation is continued until the hot water storage amount in the hot water storage tank 1 reaches the target hot water storage amount. In the post-processing time period, the operation continues until the hot water storage amount reaches the target post-processing hot water storage amount. , The above operation is continued.
[0072]
Incidentally, the detection of the amount of hot water stored in the hot water storage tank 1 is performed based on detection information of various thermistors such as the uppermost thermistor S1, the upper thermistor S2, the middle thermistor S3, and the bottom thermistor S4, and the circulating flow sensor 64.
[0073]
When the cooling operation is being performed, the heat pump operation control unit D switches the exhaust heat switching mechanism 86 to the heating state when the cooling water flowing through the cooling water passage 85 becomes equal to or higher than the set temperature for heating. The operation of the cooling water circulating means L is controlled so that is supplied to the heating unit 34 using the engine exhaust heat.
Then, the heat pump operation control unit D continuously operates the engine heat pump type cooling and heating device B even when the temperatures of all the rooms having the cooling request become equal to or lower than the cooling target temperature and the air conditioning target space is in the target air conditioning state. As described above, the operation of the cooling water circulating means L is controlled so as to supply the cooling water to the engine exhaust heat utilization type heating unit 34.
The hot water storage unit controller C operates the circulation adjusting means F in a bypass state and controls the circulation adjusting means F such that the temperature detected by the hot water thermistor 66 becomes the hot water storage set temperature (for example, 80 ° C.). ing.
[0074]
In this manner, when the cooling operation is being performed, the hot and cold water taken out from the bottom of the hot water storage tank 1 is heated by the engine exhaust heat utilizing heating unit 34 by bypassing the heat pump heating unit 33 and heated. The stored hot water is returned to the upper portion of the hot water storage tank 1 to store the hot water in the hot water storage tank 1.
In the heating operation time period, the above-described operation is continued until the hot water storage amount in the hot water storage tank 1 reaches the target hot water storage amount. In the post-processing time period, the operation continues until the hot water storage amount reaches the target post-processing hot water storage amount. , The above operation is continued.
[0075]
In addition to the description of the heat dissipation operation, the hot water circulation means E is operated to heat the hot water flowing through the circulation path 3 by the auxiliary heating unit 35, and when there is a request for additional heating, the bath operation means H is turned off. When a request for heating is made, the heating operation means J is operated, and in the bath radiating section 43 and the heating radiating section 42, the hot water and the heating terminal ( For example, by heating a heating medium from a floor heating device or a bathroom heating device), additional heating of hot water in a bathtub and circulating supply of the heating medium to a heating terminal are performed.
