METHOD FOR CONTROLLING GROUND SOURCE HEAT PUMP SYSTEM FOR SUPPLYING HOT WATER AND HEATING SPACE}

The present invention relates to a heat pump control method, and more particularly, to a control method of a heat pump system for enabling the maintenance of an optimized state of operating performance of a heat pump and a hot water generation function for heating / hot water supply.

Heat pumps are actively produced and researched on heat pumps in that they have a combined function of heating and cooling to enable a selective function as a single device. The heat pump may have various structures depending on the cycle configuration and the selection of the heat source or the load. For example, the geothermal heat pump system includes an underground heat exchanger and a heat pump, and an air conditioner that absorbs or discharges an underground heat source and / or other heat sources from the underground heat exchanger and performs cooling and heating on a building associated with the heat pump. to be. The geothermal heat pump system discharges heat in the building to the ground during cooling and absorbs the heat from the ground and supplies it to the building to perform cooling and heating operations.

FIG. 1 is a diagram showing a geothermal heat pump system. As shown in FIG. 1, a geothermal heat pump system includes a heat pump 1, an underground heat exchanger 2, and a building 3 as a heating target. The heat pump 1 includes a compressor 1a through which a refrigerant circulates, a heat source side heat exchanger 1b, an expansion device 1c, and a load side heat exchanger 1d. The load side heat exchanger 1d exchanges heat with the refrigerant of the heat pump 1 while the load side secondary fluid circulating in the building 3 requiring cooling and heating passes, and the heat source side heat exchanger 1b is underground. The heat source side secondary fluid circulating in the heat exchanger 2 passes through and exchanges heat with the refrigerant in the heat pump 1. Here, the "secondary fluid" refers to a fluid that exchanges heat with the refrigerant of the heat pump 100 while passing through the heat source side heat exchanger 120 or the load side heat exchanger 140.

However, in the heat pump according to the related art, the countermeasure for the case where a hot water supply function for heating / hot water supply is required is not appropriate. Accordingly, in order to solve the hot water production problem, it is possible to use a two-stage compression cycle as a heat pump cycle or to use a variable speed compressor to respond to the demand of hot water for heating / hot water supply. However, in the case of a heat pump using a two-stage compression cycle, the manufacturing cost is significantly increased due to a plurality of compressors, and due to the characteristics of the two-stage compression cycle, the cycle gas-liquid separator and the intermediate heat exchanger are additionally arranged, resulting in a complicated cycle design and a space.

In addition, in the case of a heat pump using a two-stage compression cycle according to the prior art, various operating parameters are generated, and the process of securing the system and securing the stability for stable operation of the system is not only complicated, but also a considerable difficulty in securing reliability. In addition, in the case of a heat pump using a variable speed compressor, the variable speed compressor is operated according to the rated rotational speed, but when the demand for high temperature water occurs, the process of increasing the load of the compressor according to the high speed rotation is accompanied. According to the variable operation of the compressor used as a component of the pump, the operating conditions of the entire system of the heat pump for mismatching and system optimization of the heat exchanger are relatively changed, and the system efficiency according to the operating conditions is lowered, resulting in the performance of the heat pump. There is a limit of high temperature water production depending on the operating conditions due to the limitation of the compressor variable capacity. In addition, there is a difficulty in employing an electronic expansion valve equipped with a separate control driver rather than a temperature-sensitive expansion valve having a mechanically simple structure that has been widely used in terms of system matching, etc. as the number of compressor rotations increases. . In addition, the manufacturing cost or the complexity of the equipment is accompanied, such as the production of a compressor driving driver and a separate equipment for removing noise according to the adoption of an inverter for changing the compressor rotation speed.

The storage unit 30 has operation mode data used for setting the operation mode of the bypass unit, more specifically, the bypass valve unit 410, and the operation mode data which is preset and stored in the storage unit 30. Includes a preset heat source minimum temperature T _SL and a preset hot water required temperature Tws. Here, the predetermined heat source minimum temperature T _SL is the lowest heat source side necessary for optimizing the operating efficiency of the heat pump unit 100 during heat exchange with the unit working fluid generated in the heat source side heat exchanger of the heat pump unit 100. Indicates the temperature. That is, when the heat source side temperature is excessively low, the efficiency is not only lowered due to a significant increase in work input into the compressor 110 of the heat pump unit 100, but also stable due to an increase in the fluctuation range of the load required for the compressor 110. Operation is difficult, requiring detection and adjustment of the lowest temperature on the heat source side that achieves heat transfer with the unit working fluid through the expansion valve to prevent the extreme load fluctuations required for these compressors and to optimize the overall operating efficiency of the heat pump unit. As a criterion for determining this, a preset heat source minimum temperature T _SL may be used. In addition, the preset high temperature water request temperature Tws, which is stored in the storage unit 30 in advance, may be used as a reference value for determining an operation need of the auxiliary heater.

The input unit 50 may be implemented as a control panel, and includes a plurality of buttons or rotary switches. The user may generate an input signal for operating the hot water production geothermal heat pump system that the user desires, including the high temperature water function signal V indicating the high temperature water function, and transmit the generated input signal to the controller 20. For example, when hot water production is required for heating or hot water supply, the user operates a predetermined button or rotary switch provided in the input unit 50 to select a hot water production function for heating / hot water supply and / or a user. Can input a desired heating temperature to a hot water temperature, that is, a hot water demand input temperature Twi. The high temperature water request input temperature Twi may be transmitted to the control unit 20 as a direct signal input by the user, and may be directly used as a criterion for determining whether to operate the high temperature water. Various modifications are possible, such as being converted into a corresponding corresponding value from a required temperature map (not shown) stored and stored, and used as a criterion for determining whether to operate the hot water.

The controller 20 establishes electrical communication with the input unit 50, the sensing unit 600, and the storage unit 30. The input unit 50 detects the input signal through the input unit 50 and the sensing unit 600, for example, the input unit ( Input sensing signals such as user set temperature and load bypass outlet / inlet temperature and / or heat source bypass outlet / inlet temperature for heating / hot water input through 50), and operation mode data preset in the storage unit 30 For example, you can compare operating mode data, such as a preset heat source minimum temperature (T _SL ) and a preset hot water demand temperature (Tws), to determine the operating mode desired by the current user and to be selected for optimization of the current system. The control signal is applied to the bypass valve unit 410 of the bypass unit 400 to perform the operation mode. The calculation unit 40 may be used in a calculation process that is performed when the control unit 20 generates a control signal applied to the bypass valve unit 410. As described above, the input unit 50 may be configured to provide a user with a load as a heating space. It may be provided as an input means for inputting a set temperature (TRS), a high temperature water set temperature (Tws), and the like, these computing unit 40 and the input unit 50 may be in electrical communication with the control unit 20.

Hereinafter will be described the operation of the hot water production geothermal heat pump system. To clarify the understanding of the invention, the operation process will be described based on the hot water production geothermal heat pump system shown in FIG.

When a signal of a high temperature water function implementation is input through the input unit 50 by a user, the control unit 20 generates a control signal for manufacturing high temperature water therefrom and transmits the control signal to the bypass unit 400. When the bypass valve unit 410 of the bypass unit 400 operates according to a control signal from the control unit 20, more specifically, the bypass valve driving unit implemented by the electric motor of the bypass valve unit 410 ( When the 413 is driven, the bypass valve 411 connected to the bypass valve driver 413 is operated to adjust the opening degree. Here, as described above, the bypass valve and the bypass valve driving unit are described in separate configurations, but various modifications are possible, such as being implemented as a single valve body. In addition, the bypass valve driving unit may be configured in various ways, such as a configuration that may be hydraulically driven in some cases other than the electric motor.

Through the bypass valve portion, the load side secondary working fluid is allowed to flow from the load flow line into the bypass line l ₄₀₀ , and the load side secondary working fluid flowing through the bypass line l ₄₀₀ is bypass heat exchanged. Will flow through group 420. At this time, the heat source side secondary working fluid flows through the heat source flow line disposed in a counter flow with the bypass line l ₄₀₀ in the bypass heat exchanger 420, and the load side 2 in the bypass heat exchanger 420 flows. Heat transfer occurs between the secondary working fluid and the heat source side secondary working fluid. That is, heat is transferred from the load side secondary working fluid to the heat source side secondary working fluid and the heat source side secondary working fluid rises in temperature by heat transferred from the load side secondary working fluid. The heat source side secondary working fluid, which has risen in temperature through heat exchange in the bypass heat exchanger 420, enters the heat source side heat exchanger 140 of the heat pump unit 100 and operates the unit on the unit flow line in which the counter flow is disposed. It exchanges heat with the fluid, ie the refrigerant. At this time, since the heat source side temperature of the heat pump unit 100 is increased, the heat input through the heat source side heat exchanger performs a function of increasing the cycle of the heat pump unit together with the input to the refrigerant through the compressor 110. That is, the cycle shown by the dotted line in FIG. 5 is a cycle (a1-b1-c1-d1; dashed line) of the heat pump unit before heat is introduced into the heat source side secondary working fluid through the bypass heat exchanger of the bypass unit 400. The cycle shown by the solid line represents the cycle a2-b2-c2-d2 of the heat pump unit after heat is introduced into the heat source side secondary working fluid through the bypass heat exchanger of the bypass unit 400. Fig. 5 superimposes the heat source side and the load side temperatures T _H1 , T _H2 , T _L1 , T _L2 to facilitate understanding of the PH diagram and the invention. The heat pump cycle a1-b1-c1-d1 before the bypass of the load side secondary working fluid through the bypass unit is input through the compressor 110 and the heat from the heat source side of the temperature T _L1 . The temperature T _H1 is formed on the load side. The heat pump cycle (a2-b2-c2-d2), which bypasses the load side secondary working fluid through the bypass unit, is connected to the heat from the heat source side of the temperature (T _L2 ; T _L2 > T _L1 ) through the bypass heat exchanger. The temperature T _H2 ; T _H2 > T _H1 is formed on the load side from the work W input through the compressor 110 to increase the temperature of the unit working fluid as the refrigerant flowing into the load side heat exchanger, thereby increasing the temperature of the unit in the load side heat exchanger. Seamless heat transfer between the working fluid and the load side secondary working fluid can be achieved. Accordingly, the temperature of the heat source side secondary working fluid is increased (ΔTL) through heat exchange between the heat source side secondary working fluid and the load side secondary working fluid through bypass of the load side secondary working fluid (ΔTL), and the heat source side secondary working fluid is increased. Heat exchange with the refrigerant increases in the heat source side heat exchanger, that is, the temperature of the unit working fluid to increase and change the cycle of the heat pump unit 100, increase the temperature of the unit working fluid in the load side heat exchanger, ultimately By increasing the temperature (△ TH) of the load-side secondary working fluid to heat exchange with the unit working fluid in the load-side heat exchanger it can be possible to make a more smooth hot water production for heating or hot water supply.

In addition, it is possible to minimize the initial driving operation time from the initial driving state to the stabilization state during the initial driving through the operation of the hot water production geothermal source heat pump system according to the present invention. That is, when the hot water production geothermal heat pump system is initially driven, more specifically, when the heat pump unit is initially driven and does not reach a stabilization state, the bypass valve portion of the bypass unit is operated to bypass the load side secondary working fluid. Via the pass line. At this time, heat transfer occurs between the load side secondary working fluid and the heat source side secondary working fluid in the bypass heat exchanger 420, and the heat pump achieves heat transfer from the heat source side heat exchanger 140 as the temperature of the heat source side secondary working fluid rises. The operating cycle of the unit 100 may be raised (see solid line in FIG. 5) to smoothly and efficiently stabilize the operating state of the heat pump unit 100.

In addition, the high temperature water production geothermal source heat pump system according to the present invention can also be used to increase the thermal efficiency of the heat pump unit. That is, the temperature signal of the heat pump unit detected from the unit temperature sensors 610; 611, 612, 613, and 614 disposed in the heat pump unit 100 and / or the temperature signal detected by the temperature sensor indicated by reference numeral 633 is transferred to the controller 20. The control unit 20 compares the preset heat source minimum temperature T _SL preset and stored in the storage unit 30 with the temperature T ₆₃₃ detected by the temperature sensor indicated by reference numeral 633. If it is determined that the heat source side temperature is formed so low that the operating state of the 100 is difficult to achieve optimized thermal efficiency, a control signal is applied to the bypass unit 400 to operate the heat source side secondary in the bypass heat exchanger 420. It is also possible to increase the efficiency of the heat pump unit, ultimately the heat pump system, by exchanging the fluid and the load side secondary working fluid.

Hereinafter, a control process of the hot water production geothermal source heat pump system of the present invention will be described with reference to FIGS. 6 to 8.

First, as shown in Figure 6, the hot water production geothermal heat pump system control method according to the present invention provides a step (S1), the input detection step (S10), the operation mode determination step (S20), the operation It includes a mode execution step (S30). In the providing step (S1) is provided a hot water production geothermal source heat pump system according to the present invention, will be described with reference to the case of Figure 4 having an auxiliary heater in order to clarify the description of the present invention. However, this is to facilitate the understanding of the present invention, various modifications are possible within the range of the control process of the hot water production geothermal heat pump system. The input unit 50 (see FIG. 2) of the geothermal heat source heat pump system 10a of high temperature water production may be implemented in a control panel type as described above. The hot water function signal V for selecting the input may be input and transmitted to the control unit 20. In addition, as described above, the sensing unit 600 detects a state of the heat pump unit 100, the load unit 200, and the heat source unit 300, and in some cases, the bypass unit 400. 600 includes flow line temperature sensors 621, 625, 631, 633 disposed on heat source flow line l ₃₀₀ and load flow line l ₂₀₀ , and flow line temperature sensors 621, 625, 631, 633 are connected to load flow line temperature sensors 621, 625. Heat source flow line temperature sensors 631, 633.

After the providing step S1, an input sensing step S10 is performed in which an input sensed signal through the input unit 50 and the sensing unit 600 is transferred to the control unit 20 in the input sensing step S10. In the input sensing step S10, the load bypass inlet temperature T ₆₂₁ , the load bypass outlet temperature T ₆₂₅ , and the unit temperature sensor 610 detected by the load flow line temperature sensors ₆₂₁ and _{625 of the} sensing unit 600. ) Is detected by the unit temperature (T ₆₁₀ ), more specifically, the refrigerant temperature (T ₆₁₄ ) in the downstream (outflow) heat pump flow line (l ₁₀₀ ) of the heat source side heat exchanger (140), of the heat source unit (200) The heat source bypass outlet temperature T _{633 of the} detected heat source side secondary working fluid, which is disposed before the inflow of the heat source side heat exchanger 140 onto the heat source flow line, is transmitted to the controller 200. In addition, a signal input by the user through the input unit 50, for example, when the user wants to produce hot water for heating / hot water, input through the heating / hot water button (not shown) provided in the input unit 50 The hot water function signal V is transmitted to the control unit 20.

Then, the control flow is passed to the operation mode determination step (S20). The operation mode determination step S20 includes an initial driving mode determination step S21. In the initial driving mode determination step (S21), the control unit 20 determines whether the hot water production geothermal source heat pump system 10, more specifically, the heat pump unit 100 is initially driven. That is, the unit temperature (T ₆₁₀ ) detected in the input sensing step (S10), more specifically the refrigerant temperature (T ₆₁₄ ) in the downstream (outflow) heat pump flow line (l ₁₀₀ ) of the heat source side heat exchanger (140). Is transmitted to the control unit 20. Meanwhile, the preset operation mode data preset and stored in the storage unit 30 includes temperature information for maintaining the efficient operation of the heat pump unit 100. The temperature information includes the minimum unit temperature Tsi of the unit heat source. It may include. When the temperature at the outlet side of the heat source side heat exchanger is smaller than the unit heat source minimum temperature Tsi, the control unit 20 determines the current operating state of the heat pump unit 100 as the initial driving state. Here, the unit heat source minimum temperature Tsi may form the same or constant relationship with the preset heat source minimum temperature T _SL as described above, and in some cases, the preset heat source minimum temperature may be used instead of the unit heat source minimum temperature. Various modifications are possible depending on the design specifications. If the control unit 20 determines that the operating state of the heat pump unit 100 is the initial driving state, the control unit 20 switches the control flow to step S22, and initially operates the operating mode of the hot water production geothermal source heat pump system. The mode is set (S22).

On the other hand, when the control unit 20 determines that the temperature of the unit working fluid on the outlet side of the heat source side heat exchanger is equal to or higher than the unit heat source minimum temperature Tsi or the preset heat source minimum temperature T _SL , the control unit 20 determines the heat pump. It is determined that the unit 100 is in the driving state, and the control flow is switched to step S23. That is, the operation mode determination step S20 may further include a high temperature water mode determination step S23. In the high temperature water mode determination step S23, the control unit 20 may include an input signal from the input unit 50 and a storage unit. Whether or not the hot water mode is determined from the preset operation mode data of 30 is determined. More specifically, when the hot water function signal (V) is input by the user from the input unit 50, the control unit 20 determines that the user wants to produce hot water for the purpose of heating / hot water supply, and control The flow is switched to step S24. In step S24, the control unit 20 compares the load bypass inflow temperature T ₆₂₁ input from the sensing unit 600 with the high temperature water request input temperature Twi input by the user through the input unit 50 to compare the current load. The temperature of the load-side secondary working fluid flowing along the flow line determines whether additional heat supply is required (S24). Here, the hot water demand input temperature (Twi) and the load bypass inlet temperature (T ₆₂₁ ) has a structure that is directly compared, but as described above the conversion through the temperature map (not shown) preset in the storage unit 30 Values may be used. That is, the temperature map is preset and stored in the storage unit 30, and the pressure gauge (not shown) disposed on the load flow line and the hot water demand input temperature Twi input through the input unit 50 by the user. By deriving a predetermined predetermined hot water demand temperature (Tws) and comparing the preset hot water demand temperature (Tws) thus obtained with the load bypass inlet temperature (T ₆₂₁ ) of the bypass unit for high temperature water production. It is determined whether the operation (S24). As such, when the control unit 20 determines that the load bypass outlet temperature is lower than the high temperature water request input temperature selected by the user or the preset high temperature water temperature corresponding thereto, the control unit 20 moves the control flow to step S25. It is determined that the operation mode to be performed by the hot water heat pump system by switching to the hot water mode (S25). On the other hand, when it is determined in step S24 that the load bypass outlet temperature is equal to or higher than the hot water demand input temperature selected by the user or the preset hot water demand temperature corresponding thereto, the control unit 20 switches the control flow to step S28. Therefore, it is determined that the direct mode that maintains the direct flow state without bypass flow of the load-side secondary working fluid is an operation mode to be executed.

On the other hand, if it is determined in step S23 that the controller 20 does not select the hot water mode by the user, the controller 20 switches the control flow to step S26. That is, the operation mode determination step further includes a thermal effect mode determination step S26, in which the control unit 20 controls the heat source bypass outlet temperature T ₆₃₃ and the preset operation mode data, more specifically, the preset heat source. The comparison is made based on the lowest temperature T _SL to determine whether the operating mode of the hot water heat pump system is the thermal efficiency mode. If the control unit 20 determines that the heat source bypass outlet temperature T ₆₃₃ is smaller than the preset heat source minimum temperature T _SL , the control unit 20 passes between the load-side secondary working fluid and the heat source secondary working fluid through the bypass heat exchanger 420. It is determined that the heat efficiency mode must be performed to increase the heat source side temperature to increase the heat source side temperature, thereby rapidly and smoothly increasing the cycle of the heat pump unit (see FIG. 5), and ultimately to enable the optimal operation of the heat pump unit (S27). ). On the other hand, when the control unit 20 determines that the heat source bypass outlet temperature T ₆₃₃ is equal to or higher than the preset heat source minimum temperature T _SL , it is determined that a separate bypass unit is unnecessary and bypasses the load side secondary working fluid. It is determined that the direct mode for circulating directly without bypassing the unit is an operation mode to be executed (S28).

As such, in the operation mode determination step (S20), the control unit 20 determines and selects an operation mode to be implemented by the hot water production geothermal source heat pump system.

Then, the control unit 20 performs an operation mode execution step (S30). The operation mode execution step S30 includes an operation mode execution step S31. In the operation mode execution step S31, the controller 20 performs individual operation modes selected and determined in step S20. That is, the initial driving mode control step (S311), the hot water mode control step (S313), the thermal efficiency control mode step (S315) and the direct mode control step (S317) are performed according to the operation mode selected in step S20. The control signal corresponding to the control signal is transmitted to the bypass valve unit 410 of the bypass unit 400, and the bypass valve driving unit 413 of the bypass valve unit 410 is operated or maintained according to each of the transmitted control signals. The opening degree of the bypass valve is controlled so that the inflow of the load side secondary working fluid into the bypass line is determined or adjusted.

On the other hand, the operation mode execution step (S30) according to the present invention may further include an auxiliary heater mode (S32). That is, after the operation mode performing step (S31), more specifically after the hot water mode control step (S313), the auxiliary heater mode (S32) for the control unit 20 to control the operation of the auxiliary heater 250 is further provided. It may be. The auxiliary heater mode S32 may include an auxiliary heater operating temperature comparing step S321 and an auxiliary heater operating step S323. In the auxiliary heater operating temperature comparing step S321, the control unit 20 controls the load bypass outlet temperature. It is determined whether the auxiliary heater is operating by comparing the T625 with the preset high temperature water request temperature Tws. Here, the preset high temperature water request temperature Tws may be configured as a conversion value output through a temperature map to the high temperature water request input temperature Twi input by the user as described above. That is, when the control unit 20 determines that the load bypass outlet temperature T625 is lower than the temperature of the high temperature water desired by the user, the control unit 20 determines that the auxiliary heater 250 needs to be operated. The operation 250 is determined to be unnecessary and the control process is terminated (S321). If it is determined in step S321 that the control unit 20 needs to operate the auxiliary heater 250, the control unit 20 applies a predetermined control signal to the auxiliary heater 250 to operate the auxiliary heater 250. Whether to maintain the operation of the auxiliary heater 250 may be made through continuous monitoring of the load bypass outlet temperature.

Through the operation mode execution step (S30) as described above, the hot water production geothermal heat pump system can perform predetermined operation modes and achieve the desired high temperature water production. The control method described above may be variously modified in a range for controlling the hot water production geothermal source heat pump system of the present invention.
