[ The heat pump device 20a other than the nth heat pump device 20an is controlled so that the variation amount assigned to the nth heat pump device 20an is smaller than the variation amount normally assigned to the heat pump device 20a ) Is determined.

For example, the variation amount allocation determination unit 305 divides the variation read by the variation reading unit 306 from the storage unit 302 into an algebra number n of the heat pump apparatus 20 at a normal time, Of the heat pump device 20 other than the nth heat pump device 20an so that the variation amount assigned to the nth heat pump device 20an is smaller than the variation amount normally assigned to the heat pump device 20a.

Specifically, for example, the target temperature of the water at the output of the nth heat pump unit 20an exceeds the first set temperature, and the variation amount allocation determination unit 305 determines whether or not each of the heat pump units 20 When the water is heated and the pressure is increased and outputted, at a predetermined timing, the amount of change assigned to the nth heat pump device 20an is made smaller than the amount of change normally assigned to the heat pump device 20an. And determines the allocation of the variation amounts of the other heat pump apparatuses 20. For example, when the target temperature of water at the output of the nth heat pump unit 20an exceeds the first set temperature, the variation amount allocation determination unit 305 determines that the respective heat pump units 20 The heat pump apparatus 20a is operated so as to increase the pressure of the first heat pump apparatus 20a and the second heat pump apparatus 20a to the second heat pump apparatus 20a at a timing when the actual temperature of the water at the output of the nth heat pump apparatus 20an exceeds the second set temperature The allocation of the variation amount of the heat pump device 20 other than the nth heat pump device 20an may be determined so as to be smaller than the variation amount assigned to the normal heat pump device 20a.

The variable-dose reading unit 306 includes a first heat pump unit 20a1, a second heat pump unit 20a2, , And reads the amount of variation that changes the temperature of the water in the entire nth heat pump unit 20an from the storage unit 302. [ For example, the variation reading unit 306 reads the data table TBL1 from the storage unit 302. [

The variation amount assignment setting unit 307 sets the variation amount assignment setting unit 307 to the heat pump apparatus 20 other than the nth heat pump apparatus 20an and the nth heat pump apparatus 20an based on the variation amount determined by the variation amount assignment determination unit 305 ) To be assigned to the variable amount.

Next, the data table TBL1 stored by the storage unit 302 according to the present embodiment will be described.

The data table TBL1 includes a first heat pump device 20a1, a second heat pump device 20a2, , And the variation amount? T that changes the temperature of the water in the whole of the nth heat pump device 20an. For example, as shown in Fig. 4, the data table TBL1 is a data table TBL1 which is a table showing the correspondence relationship between the respective amounts of temperature fluctuation DELTA T in the respective equipments (equipments 10, equipments 300, ...) .

Next, the processing of the heat pump system 1 according to the present embodiment will be described.

Here, in the heat pump system 1 according to the present embodiment, when the facility 10 cools water and the temperature of the water is lowered by DELTA T, each of the heat pump devices 20 is controlled to heat the water The processing flow of Fig. 5 showing the processing of the control device 30 will be described. It is also known in advance that the facility 10 cools the water input from the nth heat pump unit 20an through the water pipe 40 and decreases the temperature of the water by ΔT. The storage unit 302 stores the variation amount ΔT And stored in the data table TBL1. Here, the variation ΔT recorded in the data table TBL1 of the storage unit 302 by the facility 10 is calculated by the first heat pump unit 20a1, the second heat pump unit 20a2, , And it is a variation amount that changes the temperature of the water in the whole of the nth heat pump device 20an.

The variation reading unit 306 reads the variation? T corresponding to the facility 10 from the data table TBL1 of the storage unit 302 (step S1). For example, in the case of the data table TBL1 shown in Fig. 4, the variation reading unit 306 searches for and specifies the facility 10 in order from the head of the facility in the data table TBL1, (10) is specified and read out as the variation amount? T of the facility (10).

The variation amount reading unit 306 outputs the read variation amount? T to the variation amount allocation determination unit 305. [

When the variation amount? T is input from the variation amount reading unit 306, the variation amount allocation determination unit 305 determines whether the input variation amount? T, the first heat pump apparatus 20a1, the second heat pump apparatus 20a2, The nth heat pump device 20an, the input water temperature of the first heat pump device 20a1 of the most upstream, and the target outlet water temperature of the nth heat pump device 20an of the most downstream, And determines the allocation of each variation amount of the heat pump apparatus 20 at the normal time (step S2). For example, the variation amount allocation determination unit 305 determines the variation amount T of the variation amount, which is obtained by equally dividing the variation amount? T by the logarithm n of the heat pump device 20, It is decided by allocation.

The variation amount allocation determination unit 305 outputs to the variation amount allocation setting unit 307 the allocation of each variation amount of the heat pump apparatus 20 determined at the normal time.

The variation amount assignment setting unit 307 inputs the variation amounts of the heat pump apparatuses 20 at the normal time from the variation amount assignment determination unit 305. When the variation amounts of the input heat pump apparatuses 20 To each of the heat pump devices 20 (step S3). For example, when the variation amount allocation determining unit 305 determines that the variation amount of each of the heat pump apparatuses 20 is? T ÷ n, the variation amount assignment setting unit 307 sets the variation amount allocation setting unit 307 to the heat pump apparatus 20) is set to? T? N.

The temperature variation control unit 304 sets the variation amount allocation setting unit 307 to the variation amount T of the water temperature in the facility 10 and the heat amount change amount T in the facility 10 when the variation amount allocation setting unit 307 sets allocation of each variation amount of the heat pump unit 20 at the normal time, The equipment capacity of each of the pump devices 20, the variation amount T of the water temperature in the facility 10, the first heat pump device 20a1, the second heat pump device 20a2, (N-1) th heat pump device 20a (n-1), the measured value of the inlet water temperature, and the measured value of the outlet water temperature, And controls each of the heat pump apparatuses 20 (step S4).

The temperature fluctuation control unit 304 generates a control command for changing the temperature of the water and controls each of the heat pump apparatuses 20 so that each of the heat pump apparatuses 20 is heated , And outputs it to the heat pump device (20) or the facility (10) on the downstream side of the circulation path of the water.

The fluctuation amount assignment determining unit 305 determines whether or not the predetermined timing is reached when each of the heat pump apparatuses 20 is heating the water and outputting the increased pressure (step S5). Specifically, for example, when the target temperature of water at the output of the nth heat pump device 20an exceeds the first set temperature and the nth heat pump device 20an Is at a timing exceeding the second set temperature. More specifically, for example, when the target temperature of water at the output of the nth heat pump device 20an exceeds the first set temperature of 55 degrees (for example, water And the actual temperature of water at the output of the nth heat pump device 20an reaches the second predetermined temperature of 50 degrees.

In a normal case, when the fluctuation amount allocation determination unit 305 determines that the predetermined timing has not been reached (step S5, NO), the process returns to step S5.

In the normal case, when the heat pump apparatus 20 has heated each of the heat pump apparatuses 20 to output a high pressure and determines that the predetermined timing has been reached (YES in step S5) The heat pump apparatus 20a other than the nth heat pump apparatus 20an is controlled so that the variation amount assigned to the nth heat pump apparatus 20an is smaller than the variation amount normally assigned at the judgment timing (predetermined timing) (Step S6). For example, when the change amount allocation determining unit 305 has determined the allocation of the variation amount of each heat pump apparatus 20 at a normal time by? T / n, at a predetermined timing, The heat pump apparatus 20a determines that the variation amount of the heat pump apparatus 20an is lower than? T ÷ n, So that the allocation of the variation amount of the battery 20 is increased. More specifically, the variation amount allocation determining unit 305 determines whether or not the variation amount allocation of the nth heat pump unit 20an is lower than that of the nth heat pump unit 20a, It is determined by the allocation of the variation amount that can be easily realized per unit time.

The variation amount allocation determination unit 305 outputs to the variation amount allocation setting unit 307 the allocation of each variation amount of the determined heat pump apparatus 20.

The variation allocation setting unit 307 inputs the variation amounts assigned to the heat pump apparatuses 20 determined at predetermined timings from the variation amount allocation determination unit 305. The variation amounts assigned to the respective heat pump apparatuses 20 To each of the heat pump devices 20 (step S7).

The temperature variation control section 304 sets the variation amount allocation section 307 to allocate the variation amounts of the heat pump devices 20 determined at predetermined timings to the variation amount T of the water temperature in the facility 10, The equipment capacity of each of the pump devices 20, the variation amount T of the water temperature in the facility 10, the first heat pump device 20a1, the second heat pump device 20a2, (N-1) th heat pump device 20a (n-1), the measured value of the inlet water temperature, and the measured value of the outlet water temperature, And controls each of the heat pump apparatuses 20 (step S8).

Further, the number n of the heat pump apparatuses 20 may be several units if more than two units are provided.

The temperature fluctuation control unit 304 controls the temperature fluctuation amount DELTA T in the facility 10 and the equipment capability of each of the heat pump apparatuses 20 and the facility 10, the first heat pump device 20a1, the second heat pump device 20a2, ..., Based on each of the target outlet water temperature, the inlet water temperature measured value, and the outlet water temperature measured value of each of the (n-1) th heat pump device 20a (n-1) , And controls each of the heat pump apparatuses 20. The variation amount allocation determination unit 305 determines the variation amount of the heat pump apparatus 20 by using the heat pump apparatus 20a other than the nth heat pump apparatus 20an and the nth heat pump apparatus 20an disposed at the most downstream side in the water circulation path in the heat pump apparatus 20. [ The heat pump device 20a other than the nth heat pump device 20an is controlled so that the variation amount assigned to the nth heat pump device 20an is smaller than the variation amount normally assigned to the heat pump device 20a ) Is determined.
