Description

Artificial intelligence type geothermal system of complex-parameter calculation type

The present invention relates to an artificial intelligence geothermal system using a complex parameter calculation method.

The geothermal system can perform cooling, heating, and hot water supply using geothermal heat. In addition to the consumption power of the heat source equipment itself, which is a facility that directly produces heat from such a geothermal system, the pump, which is the power to transport the heat medium such as water, The conveying power is often too large.

In general, when the power consumption of the pump on the heat source side and the load side are combined, it amounts to about 30 to 40% or more of the total geothermal system. The power consumption of the heat source equipment itself is an essential power for performing cooling, cooling, hot water, etc., but the transfer power of the pump increases with control, so the transfer power of the pump is the energy of the entire geothermal system. The effect on efficiency is very large.

However, conventionally, as the pump's conveying power is fixed at a rated 100% and no other control is performed, or the pump's discharge pressure is always constantly and fixedly regulated in a basic inverter capacity control. Even though it is possible to sufficiently reduce the transport power of the pump accordingly, if the geothermal system cannot actively respond to changes in the load or the use environment, and the annual load or the use load of the building to which the geothermal system is applied is reduced accordingly. Nevertheless, it is impossible to reduce the conveying power of the pump, resulting in wasting the conveying power of the pump.

The control unit 171 uses the internal information of the artificial intelligent geothermal system 100 of the complex parameter calculation method input through the internal information input unit 172 to provide the cooling/heating supply pump 160 and the cooling/heating geothermal source. It controls the output of at least one of the pump 150, the hot water supply pump 130, and the hot water geothermal source pump 140, and a detailed operation description thereof will be described later.

The heat source three-way valve 146 may be adjusted so that at least a portion of the circulating fluid flowing from the cooling/heating geothermal heat pump 110 toward the underground heat exchange member 103 flows toward the hot water geothermal heat pump 120.

The heat source three-way valve 146 is installed on the heating and cooling side heat pump header connection pipe 155, and a three-way bypass pipe 147 extends from the heat source three-way valve 146, and the three-way bypass pipe 147 is It is connected to the header heat pump connection pipe 144 on the hot water supply side. Then, when the heat source three-way valve 146 opens the three-way bypass pipe 147 side, a part of the circulation fluid flowing along the heating and cooling-side heat pump header connection pipe 155 passes through the three-way bypass pipe 147 It flows through and then flows through the hot water-side header heat pump connection pipe 144 to pass through the hot water geothermal heat pump 120.

When the cooling and heating geothermal heat pump 110 provides cooling to the customer, and the hot water geothermal heat pump 120 is operating, the automatic control member 170 is The heat source three-way valve 146 is controlled so that at least a part of the circulating fluid flowing toward the heat exchange member 103 flows toward the hot water supply geothermal heat pump 120, and the geothermal heat exchange from the cooling/heating geothermal heat pump 110 accordingly.

Of course, the automatic control member 170 may receive the meteorological data from the outside through the external information input unit 173 as described above, and the cooling and heating geothermal heat pump 110 and the hot water geothermal heat pump 120 It is also possible to use the self-temperature detection value by its own temperature sensor installed in, and this can be selectively applied.

Hereinafter, the control unit 171 will be described in detail for controlling the output of the cooling/heating supply pump 160, but this description includes the cooling/heating geothermal heat source pump 150, the hot water supply pump 130, and the hot water supply geothermal source. The same principle is applied to the pump 140, and the overlapping description thereof will be replaced and omitted herein.

Of course, the control unit 171 controls the corresponding pump using information on the control target pump. For example, when the control unit 171 controls the hot water supply pump 130, information on the cooling/heating supply pump 160 in the matters regarding the control of the cooling/heating supply pump 160 below Control is performed by substituting information on the supply pump 130.

In addition, when the outside air temperature and waste heat recovery are not reflected in the following calculation formula, the input value of the corresponding item becomes O, so the corresponding item is not reflected in the calculation.

The control unit 171 calculates the output of the cooling/heating supply pump 160 according to the following calculation formula, and controls the operation of the cooling/heating supply pump 160 to match the calculated value.

Pump output = compressor output × a + outside air temperature × b + pump discharge pressure × c + waste heat recovery × d + e

Here, each of the above items is as follows.

-Pump output: an output that is a control target from a pump that is a control target of the control unit 171 (here, the cooling/heating supply pump 160)

-Compressor output: the output of the geothermal heat pump compressor (here, the cooling and heating compressor 111) to which the pump to be controlled by the control unit 171 is associated

-a: Compressor output proportionality constant (a≥0)

-Outside temperature: A temperature detection value by the outside temperature sensor 175

-b: Outside temperature proportional constant ('+ value' for cooling,'-value' for heating)

-Discharge pressure of the pump: Discharge pressure of the pump that is the control target of the control unit 171 (here, the cooling/heating supply pump 160) (a value detected by the cooling/heating supply discharge pressure sensor 161)

-c: discharge pressure proportional constant (c≥0 or c<0)

-Waste heat recovery: When the cooling and heating geothermal heat pump 110 provides cooling to the customer, and the hot water geothermal heat pump 120 is operating, the heat source three-way valve 146 is the three-way bypass pipe 147 ) Degree of opening (0-100%)

-d: Waste heat recovery proportional constant (d≤0)

-e: correction factor

Here, the above constant values a, b, c, d, e are preset according to the conditions of the site to which the artificial intelligence geothermal system 100 of the above complex parameter calculation method, such as building height, insulation degree, and pipe length, is applied. The values are set to be different for each site depending on the site to which the artificial intelligence geothermal system 100 of the complex parameter calculation method is applied, but the artificial intelligence geothermal system 100 of the complex parameter calculation method is applied. In a single site, it is always maintained at a constant value. Each constant value additionally presented below is also the same.

On the other hand, among the above items, the'compressor output' item is a pipe (here, the heating and cooling side heat pump unit connection pipe 164) in which the pump that is the control target of the control unit 171 (here, the cooling/heating supply pump 160) is installed. ) And the temperature difference (ΔT) of the paired pipe for circulation of the corresponding pipe and the circulating fluid (here, the heating and cooling unit heat pump connection pipe 167) (that is, the heating and cooling unit temperature sensor 162) And the difference between the temperature detection value of the heat pump temperature sensor 163 of the heating/cooling unit).

Of course, for other pumps (here, the cooling and heating geothermal source pump 150, the hot water supply pump 130, and the hot water supply geothermal pump 140), the output of the compressor is converted to the temperature difference (ΔT) of the respective pipes as above. Can be replaced.

In the following, each of the above items will be described in detail.

(1) Compressor output

The cooling and heating load or hot water supply load of the customer to which the artificial intelligent geothermal system 100 of the complex parameter calculation method is applied is relatively small, or sufficient cooling and heating is performed as much as the amount required for the customer, so that the indoor temperature of the customer is set. When the temperature approaches, when the output of the cooling/heating geothermal heat pump 110 is reduced, the compression ratio of the cooling/heating compressor 111 is reduced together, and the heat exchange capacity of the load side and the heat source side of the cooling/heating geothermal heat pump 110 This is reduced, and the temperature difference of the circulating fluid that advances to the cooling/heating geothermal heat pump 110 is reduced, and at this time, the control unit 171 interlocks the output of the cooling/heating supply pump 160 to reduce it to a predetermined ratio. Note that, while the temperature difference of the circulating fluid entering the cooling/heating geothermal heat pump 110 can be maintained as it is by a preset amount, power consumption of the cooling/heating supply pump 160 can be reduced.

In addition, since the capacity of the cooling/heating compressor 111 of the cooling/heating geothermal heat pump 110 and the capacity of the cooling/heating supply pump 160 are generally different, a By multiplying by and adding the correction factor e, the pump output for the cooling and heating supply pump 160 can be approximated.

(2) Outside temperature

Since the outdoor air temperature throughout the year is relatively high in summer and relatively low in winter, the load for hot water is relatively low in summer, and there is no need to increase the supply temperature for hot water relatively too high. For example, hot water is supplied at a level of about 50℃ only in winter, and hot water is supplied at a level of about 40℃ during changing seasons such as autumn and spring, and even when hot water is supplied at a level of about 35℃ in summer, it is used as living water. While there is no great inconvenience to the following, unnecessary consumption of heating energy of the hot water geothermal heat pump 120 can be prevented. That is, when the outside temperature detected by the outside temperature sensor 175 is below -5°C, the control unit 171 supplies the hot water supply temperature at a level of about 50°C, and the outside temperature sensor 175 When the sensed outside air temperature is above minus 5°C, the control unit 171 gradually lowers and supplies the hot water supply temperature in conjunction with the outside air temperature, thereby heating for hot water supply in the hot water geothermal heat pump 120. Energy can be reduced.

The hot water supply temperature can be calculated by the following equation.

Hot water supply temperature = 50℃-outside air temperature × f + g

(However, 30℃ ≤ the hot water supply temperature ≤ 50℃)

Here, each of the above constants is as follows.

-f: Proportional constant of outside air temperature during hot water supply (f≥0)

-g: correction factor for outside air temperature during hot water supply

In the case of a winter heating operation, the hot water supply temperature during heating of the circulating fluid supplied to the indoor unit 102 for heating may be calculated by the following equation.

Hot water supply temperature during heating = 60℃-outside temperature × h + i

(However, 40℃ ≤ the hot water supply temperature during the above heating ≤ 60℃)

Here, each of the above constants is as follows.

-h: Outside air temperature proportional constant during heating (h≥0)

-i: Outside temperature correction factor during heating

In the case of cooling operation in summer, the cold water supply temperature when cooling the circulating fluid supplied to the indoor unit 102 for cooling may be calculated by the following equation.

Cooling water supply temperature = 15℃-outside temperature × j + k

(However, 7℃ ≤ cold water supply temperature for the above cooling ≤ 15℃)

Here, each of the above constants is as follows.

-j: Outside air temperature proportional constant during cooling (j≥0)

-k: correction factor for outside air temperature during cooling

Here, the specific values presented in the above calculation formulas are variably determined by the automatic control program applied to the site according to the site to which the artificial intelligence geothermal system 100 of the complex parameter calculation method is applied.

Meanwhile, in addition to reducing the power consumption of the artificial intelligence geothermal system 100 of the complex parameter calculation method through the control of the hot water supply temperature, the hot water supply temperature during the heating, and the cold water supply temperature during the cooling, Artificial intelligence of the complex parameter calculation method by controlling the flow rate of hot water when heating the circulating fluid supplied to the indoor unit 102 and the flow rate of cold water when cooling the circulating fluid supplied to the indoor unit 102 for cooling It is also possible to reduce the power consumption of the geothermal system 100. Since the power consumption of the cooling/heating supply pump 160 is proportional to the cube of the flow rate in the capacity variable control, when the flow rate of the cooling/heating supply pump 160 is made half of the 100% rated flow rate, the cooling/heating supply pump 160 The power consumption is 1/8.

(3) Pump discharge pressure

When the load usage at the customer is increased, the pressure in the pipe connected to the cooling/heating supply pump 160 (here, the heating/cooling side heat pump unit connection pipe 164) decreases, and the load usage at the customer is reduced. When it decreases, the pressure in the pipe connected to the cooling/heating supply pump 160 increases, and the change in pressure in the pipe connected to the cooling/heating supply pump 160 is sensed by the cooling/heating supply discharge pressure sensor 161, By controlling the number of revolutions of the cooling and heating supply pump 160 in the control unit 171, the output of the cooling and heating supply pump 160 is operated in conjunction with the load usage at the customer throughout the year, and the cooling and heating supply pump 160 To prevent excessive or insufficient operation of the unit, thereby reducing the consumption power of the heating and cooling supply pump 160.

The control method of the discharge pressure of the pump has a very fast response speed and is easy to control.

The target flow rate of the heating and cooling supply pump 160 using the discharge pressure of the pump is calculated by the following equation.

Here, each of the above items is as follows.

-Q: Target flow rate of the heating and cooling supply pump 160

-K: flow constant

-P: discharge pressure of the pump

(4) Waste heat recovery

When the cooling/heating geothermal heat pump 110 provides cooling to the customer and the hot water geothermal heat pump 120 is operating, the waste heat recovery operation is possible.

During the waste heat recovery operation, at least a portion of the circulating fluid flowing from the cooling/heating geothermal heat pump 110 toward the underground heat exchange member 103 passes through the heat source three-way valve 146 through the return header 105. The rest of the circulation fluid flowing into the underground heat exchange member 103 and flowing from the cooling/heating geothermal heat pump 110 toward the underground heat exchange member 103 is connected to the three-way bypass pipe 147 and the hot water side header heat pump The evaporation heat source of the hot water geothermal heat pump 120 is reinforced by flowing into the hot water supply geothermal heat pump 120 through the pipe 144. At this time, since the heat dissipation of the condensed heat in the cooling/heating geothermal heat pump 110 becomes relatively more active, the condensing power is reinforced, and thus the flow rate of the circulating fluid is relatively less required in the cooling/heating geothermal heat pump 110. Accordingly, the control unit 171 controls the flow rate of the circulating fluid in the hot water supply geothermal source pump 140 and the cooling/heating geothermal source pump 150 to be reduced by approximately 30 to 50%.

The circulation fluid flowing into the hot water supply geothermal heat pump 120 through the three-way bypass pipe 147 and the hot water side header heat pump connection pipe 144 is the hot water supply geothermal heat pump 120 from the supply header 104 It is mixed with the circulating fluid flowing into and returned to the water return header 105 together.

On the other hand, the control unit 171 has its own memory, and the user sets it with a wired or wireless remote control (not shown) in the indoor of the consumer and maintains it for a predetermined time (for example, 10 minutes) or more. Among the set values for each customer, such as set temperature, air volume, wind direction, operation option, etc., the set value with the highest cumulative frequency for each item is stored in the memory of the control unit 171, and then in the memory of the control unit 171. The stored set values are the default values of the initial settings of the cooling/heating geothermal heat pump 110 and the hot water geothermal heat pump 120 when the cooling/heating geothermal heat pump 110 and the hot water geothermal heat pump 120 are operated next time. value), the cooling and heating geothermal heat pump 110 and the hot water geothermal heat pump 120 may be operated according to their default values.

In addition, instead of storing and using the set value with the highest cumulative frequency for each item as described above, among the meteorological data received through the external information input unit 173, the outdoor wet bulb temperature and globe temperature (radiation temperature) , Using the dry bulb temperature, calculate the WBGT according to the following formula, and then according to the WBGT, the user sets the remote control in the indoor of the consumer and maintains the set temperature for the consumer for longer than the preset time, air volume, The set value with the highest cumulative frequency for each item among set values for each customer such as wind direction and operation option is stored in the memory of the control unit 171, and then the set values stored in the memory of the control unit 171 are next time the cooling and heating. When the geothermal heat pump 110 and the hot water geothermal heat pump 120 are operated, the cooling and heating geothermal heat pump 110 and the hot water geothermal heat pump 120 are presented as default values of the initial settings, and the cooling/heating geothermal heat The pump 110 and the hot water geothermal heat pump 120 may be operated according to their default values.

WBGT = (wet bulb temperature × 0.7) + (globe temperature × 0.2) + (dry bulb temperature × 0.1)

According to the selection of the remote control for the control unit 171 or the artificial intelligence reset button directly connected to the control unit 171, all memory values stored in the memory of the control unit 171 are deleted, and the control unit 171 Can be initialized.
