[0054] In this embodiment, a method for controlling an underground air conditioner is provided. Figure 2 is a flow chart of a method for controlling an underground air conditioner according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0055] Step S202, detecting the actual outlet water temperature of the condenser end of the downhole air conditioner, wherein the downhole air conditioner comprises a water delivery pump deployed on the ground and a water power component deployed underground, the water power component is installed on the water delivery pipeline of the water delivery pump, and is used to drive the compressor of the downhole air conditioner;

[0056] The underground air conditioner of this embodiment can be deployed and installed in underground working workplaces such as mines, manholes, underground tunnels, and underground machine rooms.

[0057] The water supply pipeline from the water pump on the ground to the hydraulic components underground generates a pressure difference, which brings energy.

[0058] Step S204, adjusting the power parameters of the water power component according to the actual outlet water temperature;

[0059] Through the above steps, the actual outlet water temperature of the condenser end of the downhole air conditioner is detected, wherein the downhole air conditioner includes a water supply pump deployed on the ground and a hydrodynamic component deployed underground, and the hydrodynamic component is installed on the water supply pipeline of the water supply pump to drive the compressor of the downhole air conditioner; the power parameters of the hydrodynamic component are adjusted according to the actual outlet water temperature, and the potential energy generated by the water pressure is converted into the kinetic energy of the compressor through the hydrodynamic component by utilizing the pressure difference from the ground to the underground in the water supply pipeline, and the potential energy of the high-pressure ground water is converted into the energy of the compressor, thereby realizing a downhole air conditioner powered by water resources, avoiding the installation of generators or wires underground, solving the technical problem in the related technology that ground water cannot be used to drive the air-conditioning compressor, and expanding the applicable working conditions of the air conditioner.

[0060] Figure 3It is a schematic diagram of the deployment of the underground air conditioner in an embodiment of the present invention, including a water supply pump, a compressor, a condenser, an evaporator, a cooling water tank, a chilled water tank, a bypass valve 1 (a first bypass valve), a bypass valve 2 (a second bypass valve), an air cooler, electronic regulating valves 1 to 3, a water supply pump, etc.

[0061] In one implementation of the present embodiment, adjusting the power parameters of the hydraulic power component according to the actual outlet water temperature includes: determining the rated outlet water temperature of the condenser of the downhole air conditioner; calculating a first temperature deviation between the actual outlet water temperature and the rated outlet water temperature; and controlling the opening of the first bypass valve based on the first temperature deviation, wherein the hydraulic power component includes a hydraulically driven pump and a first bypass valve, and the hydraulically driven pump and the first bypass valve are connected in parallel to the water supply pipeline.

[0062] The water pump delivers surface water to the ground. The surface water passes through the rock layer and is heated to 30℃ water. Due to the height difference of one kilometer, the water pressure is as high as 10Mpa or more. A new type of hydraulic pump and compressor combination structure is adopted to output the potential energy of high-pressure water into mechanical energy. The compressor is driven by the transmission parts such as the mechanical connecting rod between the hydraulic pump and the compressor. The water flow through the hydraulic pump is adjusted through the first bypass valve connected in parallel with the hydraulic pump, and the kinetic energy generated by the hydraulic pump is controlled to work on the compressor, thereby controlling the frequency of the compressor.

[0063] After the condenser of the underground air conditioner generates condensation heat during refrigeration, the cooling water in the cooling water pipeline flowing through the condenser will dissipate the heat, so that the actual outlet water temperature at the end of the condenser reaches the rated outlet water temperature. By using the first temperature deviation between the actual outlet water temperature of the condenser and the rated outlet water temperature to adjust the opening of the first bypass valve, the water flow rate flowing through the hydraulically driven pump is controlled, and then the driving force of the hydraulically driven pump is controlled, which can play a role in adjusting the power parameters of the hydraulic power component, thereby realizing adaptive control of the hydraulic power component over the compressor.

[0064] Optionally, the hydraulic component also includes a gate valve, which is connected to a water supply pipeline in parallel with the hydraulically driven pump. When the water supply pump is running, the gate valve is opened, and the underground air-conditioning unit is started and operated. The water flow through the pump body of the hydraulically driven pump is shut off by the gate valve. When the gate valve is disconnected, the unit is closed, the gate valve is started, and the unit is opened. The flow through the hydraulically driven pump is controlled by the opening of the first bypass valve.

[0065] In one example, controlling the opening of the first bypass valve based on the first temperature deviation includes: determining whether the first temperature deviation is greater than or equal to a first preset value; if the first temperature deviation is greater than or equal to the first preset value, determining whether the actual outlet water temperature is greater than the rated outlet water temperature; if the actual outlet water temperature is greater than the rated outlet water temperature, lowering the opening of the first bypass valve; if the actual outlet water temperature is less than the rated outlet water temperature, increasing the opening of the first bypass valve.

[0066] Optionally, the rated outlet water temperature is configured to be 53°C to 58°C, with a first preset value of 1.5°C. It can also be flexibly adjusted based on specific operating parameters and performance requirements.

[0067] In an application scenario, the water supply pump is running, the gate valve is opened, and the unit is started. After t time, the actual outlet water temperature T1 of the cooling water is detected, the rated outlet water temperature Trated is preset, and the first temperature deviation is A. It is judged whether |T1-Trated|≥A: When |T1-Trated|<A, the current opening of the first bypass valve is maintained, and subsequent processing is performed (such as after t time, the indoor temperature T is detected, and the load Q and water flow are calculated and the indoor temperature T is determined); when |T1-Trated|≥A, it is judged whether T1-Trated>0: when T1-Trated<0, the opening of the first bypass valve is increased by b%, and when it is adjusted to ≥100%, the bypass valve 1 is fully opened; when T1-Trated>0, the opening of the bypass valve 1 is reduced by b%, and when it is adjusted to ≤0%, the first bypass valve is fully closed.

[0068] In this example, if the temperature difference between the actual outlet water temperature and the rated outlet water temperature is large, greater than or equal to the first preset value, the heat release of the condenser of the downhole air conditioner is too little or too much, and it is necessary to adjust the power parameters of the hydraulic component and then adjust the frequency of the compressor.

[0069] In the manner of this example, the opening of the first bypass valve of the hydraulic component is adjusted based on the temperature difference and size between the actual outlet water temperature and the rated outlet water temperature. If the actual outlet water temperature is too high, the opening is lowered to increase the water flow through the hydraulically driven pump, which can increase the frequency of the compressor. Conversely, the opening is lowered to reduce the frequency of the compressor, thereby achieving more accurate control of the compressor frequency of the downhole air conditioner.

[0070] In a real-time scenario of the present embodiment, after adjusting the power parameters of the water power component according to the actual outlet water temperature, it also includes: detecting the temperature parameters of the downhole air conditioner, wherein the downhole air conditioner includes a cooling water pipeline and a chilled water pipeline connected to the water outlet end of the water power component, the cooling water pipeline flows through the condenser of the downhole air conditioner, and the chilled water pipeline flows through the evaporator of the downhole air conditioner; the water flow of the cooling water pipeline and the chilled water pipeline is controlled according to the temperature parameters.

[0071] Cooling water pipelines and chilled water pipelines are also deployed underground, using surface water for cooling to avoid the impact of scaling caused by using mine water for heat exchange on the performance of refrigeration equipment.

[0072] By connecting the cooling water pipeline and the chilled water pipeline at the water outlet of the hydraulic component, the cooling water pipeline and the chilled water pipeline can respectively exchange heat with the condenser and evaporator of the underground air conditioner, thereby improving the utilization rate of underground water resources and the heat exchange efficiency of the condenser and evaporator.

[0073] In one example, controlling the water flow of the cooling water pipeline and the chilled water pipeline according to the temperature parameter includes: using the temperature parameter to calculate the working surface load of the downhole air conditioner; calculating the first water flow of the chilled water pipeline based on the working surface load, and calculating the second water flow of the cooling water pipeline based on the working surface load; adjusting the opening of the diverter valve based on the ratio between the first water flow and the second water flow, wherein the diverter valve is deployed at the water inlet end of the cooling water pipeline or the chilled water pipeline.

[0074] Figure 4 This is a flow chart of water flow control in an embodiment of the present invention. The diverter valve is an electronic regulating valve 1. The working surface load Q required for the working surface refrigeration is calculated within the period T, and the required chilled water flow q1 and cooling water flow q2 are calculated in combination with the set chilled water inlet and outlet water temperature difference Δt1 and cooling water inlet and outlet water temperature difference Δt2. The electronic regulating valve 1 is adjusted according to the ratio of the chilled water flow q1 and the cooling water flow q2.

[0075] By adopting the solution of this embodiment, accurate diversion of the chilled water pipeline and the cooling water pipeline at the water outlet end of the hydrodynamic component is achieved, so that the water flow ratio of the chilled water pipeline and the cooling water pipeline is adapted to the working surface load of the downhole air conditioner, the downhole air conditioner is adaptively loaded, and the stability of the entire unit is improved.

[0076] In some implementation scenarios, after adjusting the opening of the diverter valve based on the ratio between the first water flow rate and the second water flow rate, the flow difference between the sum of the first water flow rate and the second water flow rate and the ground water flow rate of the water supply pump is also calculated, and the opening of the water supply valve is controlled according to the flow difference. The water supply valve is connected between the water outlet of the chilled water tank (or cooling water tank) and the water inlet of the chilled water pipeline and the cooling water pipeline.

[0077] like Figure 4As shown, the water supply valve is an electronic regulating valve 3, and it can also determine whether q1+q2>the ground water flow qground of the water supply pump. When q1+q2>the ground water flow qground, the water supply pump is turned on, and the opening of the electronic regulating valve 3 and the opening of the water supply pump are adjusted according to the water supply flow q3 (q3=qground-q1-q2). According to the ratio of the chilled water flow q1 and the cooling water flow q2, the electronic regulating valve 2 is adjusted, and the indoor temperature T is returned to the detection room, and the load Q and water flow are calculated; when q1+q2≤the ground water flow qground, the current opening of the water supply valve is maintained, and the indoor temperature T is returned to the detection room, and the load Q and water flow are calculated.

[0078] Optionally, using the temperature parameter to calculate the working surface load of the underground air conditioner includes: determining the air supply volume of the air cooler at the end of the unit of the underground air conditioner; and calculating the working surface load Q1 of the underground air conditioner using the following formula:

[0079] Q1=q v * 空 *(h t内 -h t设 );

[0080] Among them, q v is the air supply volume, h t内 is the enthalpy of the indoor temperature, h t设 is the enthalpy value of the set temperature, ρ 空 is the air density underground, wherein the temperature parameter includes the indoor temperature and the set temperature.

[0081] According to the above formula, calculate the working surface load Q1, q required by the user v is the air supply volume at the end of the unit at this time, ρ 空 is the density of air, h t内 and h t设 The enthalpy value corresponding to the temperature can be obtained by looking up the table.

[0082] By adopting the above scheme of this embodiment, the calculation of the air-conditioning working surface load under underground working conditions is realized, and the accuracy of the working surface load is improved.

[0083] Optionally, calculating the first water flow rate of the chilled water pipeline based on the working surface load includes: detecting a first inlet and outlet water temperature difference of an evaporator of the underground air conditioner; and calculating the first water flow rate q of the chilled water pipeline using the following formula: 1水 :

[0084] q 1水 =Q1 / c*ρ 水 *Δt1;

[0085] Among them, Q1 is the working surface load, c is the specific heat capacity of water, ρ 水is the density of water, and Δt1 is the first inlet and outlet water temperature difference.

[0086] According to the formula, the required chilled water flow q is calculated 1水 , Q1 is the working surface load calculated by the previous formula, c is the specific heat capacity of water, ρ 水 is the density of water, Δt1 is the temperature difference between the inlet and outlet water of the chilled water, Δt1 = the inlet water temperature of the evaporator - the outlet water temperature of the evaporator, which is collected by the temperature sensor installed on the chilled water pipeline (the inlet and outlet ends of the evaporator).

[0087] By adopting the solution of this embodiment, by introducing the first inlet and outlet water temperature difference of the evaporator and the working surface load, the hot water exchange flow of the air-conditioning evaporator under underground working conditions is predicted, thereby improving the precise control of the flow of the chilled water pipeline.

[0088] Optionally, calculating the second water flow rate of the cooling water pipeline based on the working surface load includes: determining the real-time input power of the downhole air conditioner, and detecting the second inlet and outlet water temperature difference of the condenser of the downhole air conditioner; calculating the condensation heat Q2 of the condenser using the working surface load and the real-time input power; and calculating the second water flow rate q of the cooling water pipeline using the following formula: 2水 :

[0089] q 2水 =Q2 / c*ρ 水 *Δt2;

[0090] Among them, Q2 is the condensation heat, c is the specific heat capacity of water, ρ 水 is the density of water, and Δt2 is the second inlet and outlet water temperature difference.

[0091] According to Q2=Q1+W, the condensation heat that needs to be eliminated by the underground air-conditioning unit is calculated. Q1 is the working surface load required by the user calculated above, and W is the input power of the underground air-conditioning unit at this time, which can be read from the controller.

[0092] According to the above formula, the required cooling water flow rate q2 is calculated, Q2 is the condensation heat calculated by the previous formula, c is the specific heat capacity of water, ρ is the density of water, q2 is the estimated cooling water flow rate, and Δt2 is the temperature difference between the cooling water inlet and outlet.

[0093] By adopting the solution of this embodiment, by introducing the second inlet and outlet water temperature difference of the condenser and the working surface load, the hot water exchange flow rate of the air-conditioning condenser under underground working conditions can be predicted, thereby improving the precise control of the cooling water pipeline flow rate.

[0094] In one implementation of the present embodiment, after adjusting the power parameters of the water power component according to the actual outlet water temperature, it also includes: detecting the temperature parameters of the downhole air conditioner, wherein the downhole air conditioner also includes an air cooler and a chilled water pipeline deployed at the water outlet end of the water power component, and the chilled water pipeline flows through the evaporator and the air cooler in sequence; adjusting the power parameters of the air cooler according to the temperature parameters.

[0095] According to the solution of this embodiment, after the chilled water flows through the evaporator for cooling, it enters the air cooler to perform the task of cooling and dissipating heat. The power parameters of the air cooler are adjusted by the temperature parameters, thereby realizing adaptive load control of the air cooler.

[0096] In one example, adjusting the power parameters of the air cooler according to the temperature parameters includes: determining the indoor temperature and the set temperature in the temperature parameters, wherein the air cooler includes a second bypass valve and a hydraulic fan, and the hydraulic fan and the second bypass valve are connected in parallel to the chilled water pipeline; calculating the second temperature deviation between the indoor temperature and the set temperature; judging whether the second temperature deviation is greater than a second preset value; if the second temperature deviation is greater than the second preset value, judging whether the indoor temperature is greater than the set temperature; if the indoor temperature is greater than the set temperature, increasing the opening of the second bypass valve; if the indoor temperature is less than the set temperature, lowering the opening of the second bypass valve.

[0097] Optionally, the second preset value may be selected as 1 to 1.5 degrees.

[0098] In an implementation scenario, after adjusting the opening of the first bypass valve, after t time, detect the indoor temperature Tin and the indoor set temperature Tset, calculate the load Q and water flow, and determine the indoor temperature Tin and the indoor set temperature Tset. Determine whether |Tin-Tset|≥B: When |Tin-Tset|<B, maintain the current opening of the second bypass valve, and return to detecting the cooling water outlet water temperature T1 and the designed outlet water temperature Trated; When |Tin-Tset|≥B, determine whether Tin-Tset>0: When Tin-Tset>0, and Tin-Tset>0 is detected twice in succession, and the gate valve is disconnected, open the gate valve, start the unit, and return to detecting the indoor temperature Tin and the indoor set temperature Set temperature Tset; when Tinternal-Tset>0, and Tinternal-Tset>0 for two consecutive tests, but the gate valve is open, the bypass valve 2 opening is adjusted up by a%, when it is adjusted to ≥100%, the bypass valve 2 is fully opened; when Tinternal-Tset<0, the bypass valve 2 opening is adjusted down by a%, when it is adjusted to 0%, the bypass valve 2 is fully closed, the hydraulic fan does not rotate, when Tinternal-Tset≤0 is detected three times in a row, the gate valve is closed, the water supply pump is turned off, and the bypass valve 1 is fully opened. After adjusting the bypass valve 2 and the gate valve, return to the test cooling water outlet water temperature T1 and the design outlet water temperature Tset.

[0099] In the manner of this example, the opening of the second bypass valve of the hydraulic fan is adjusted based on the second temperature deviation between the indoor temperature and the set temperature. If the indoor temperature is too high, the opening is increased to increase the water flow through the hydraulic fan, thereby increasing the speed of the hydraulic fan. Conversely, the opening is lowered to reduce the speed of the hydraulic fan, thereby achieving more accurate control of the speed of the hydraulic fan of the underground air conditioner.

[0100] Figure 5 This is a flow chart of the automatic adaptive load control of the underground air conditioner in an embodiment of the present invention. The water supply pump is running, the gate valve is opened, and the unit is started and operated. After t time, the cooling water outlet water temperature T1 and the designed outlet water temperature Trated are detected, T1 and Trated are judged, and the bypass valve 1 is adjusted based on the judgment result. After t time, the indoor temperature Tin and the indoor set temperature Tset are detected. On the one hand, the load Q and the water flow are calculated based on Tin and Tset. On the other hand, Tin and Tset are judged, and the bypass valve 2 and the water supply valve are adjusted based on the judgment result.

[0101] By adopting the scheme of this embodiment, the potential energy of high-pressure surface water is used to drive the compressor of the refrigeration system, and the frequency of the compressor is adjusted by adjusting the bypass valve 1 of the compressor to adapt it to the load demand of the working surface; when the potential energy of the high-pressure water is fully utilized, it becomes low-pressure water, which is supplied to chilled water and cooling water in two ways, and the flow rates of chilled water and cooling water are distributed through the electronic regulating valve 2 installed in the chilled water circuit; after completing the task of eliminating the condensation heat, the cooling water is recycled to the cooling water tank and used for underground production operations; the chilled water enters the air cooler, and after completing the task of cooling and dissipating the heat, it is recycled to the chilled water tank and used for underground production operations and system replenishment, and the flow rates of chilled water and cooling water are distributed through the bypass valve 2 to adapt them to the load demand of the working surface. The water from the hydraulically driven pump is sent to the evaporator and condenser in two ways, and the specific flow distribution is adjusted by the electronic regulating valve 1; the cooling water outlet is stored in the cooling water tank for underground production; the chilled water outlet is sent to the air terminal, and through the bypass valve 2 connected in parallel with the air terminal, the air volume of the hydraulic fan is controlled to adapt to the temperature changes of the working face; the chilled water outlet from the air cooler and the hydraulic fan is stored in the chilled water tank for underground production and water replenishment; when the system does not need water replenishment, the electronic regulating valve 3 is fully closed, and when the system needs water replenishment, the electronic regulating valve 3 and the water replenishment pump are used to control the flow, and the electronic regulating valve 2 is used to control the water replenishment amount of chilled water and cooling water.

[0102] By adopting the scheme of this embodiment, the potential energy of high-pressure surface water is converted into the energy of the compressor, which effectively utilizes the potential energy of high-pressure water, and converts the high-pressure water into low-pressure water, which is divided into two ways, namely, chilled water and cooling water, to enter the refrigeration unit, so that one water has two uses; the cooling water outlet and the chilled water outlet are stored in the cooling water tank and the chilled water tank respectively, and are used for underground production operations, saving precious underground water resources, and achieving three uses of one water; when the surface water flow does not meet the refrigeration demand, and because the water supply pump is on the ground and the flow cannot be adjusted in time, the water in the chilled water tank can be used as replenishing water, so as to adapt to the underground load demand in time, and achieve four uses of one water.
