Description

Technical Field

[0001] This invention relates to the field of dry steam humidifier performance testing technology, and in particular to a method and apparatus for testing the humidification efficiency of a dry steam humidifier. Background Technology

[0002] The current national standard "Humidifiers for Air Conditioning Equipment" (GB / T 29736-2013) stipulates that the efficiency of dry steam humidifiers is tested using the air humidity difference method. This method calculates the change in air humidity by measuring the dry-bulb and wet-bulb temperatures of the air before and after the humidifier; combined with the airflow rate (determined by the static pressure difference before and after the nozzle) and the amount of condensate discharged by the humidifier, the humidification efficiency is finally calculated.

[0003] According to the national standard, the steam supply of a humidifier is equal to the sum of the humidification amount measured on the air side and the condensate amount discharged by the humidifier under test, while the humidification efficiency is equal to the ratio of the humidification amount measured on the air side to the steam supply of the humidifier × 100%.

[0004] The humidification efficiency measured by this method is inaccurate under low air temperature and high humidification conditions. This is because the humidified air is prone to condensation when it flows through the inner wall of the humidifier's test section duct. This means that extra condensate water is precipitated on the inner wall of the duct. This part of the condensate water is not included in the amount of condensate water discharged by the humidifier, resulting in a lower measured amount of steam and an overestimation of the humidification efficiency, leading to inaccurate measurement results. Summary of the Invention

[0005] This invention provides a method and apparatus for detecting the humidification efficiency of a dry steam humidifier. It addresses the issue of inaccurate steam supply measurement in current national standards under low air temperature and high humidification conditions, leading to an overestimation of humidification efficiency. The method replaces the steam supply calculated from the air-side measurement and the condensate discharge from the humidifier in the national standard with the steam supplied by a steam generator to the dry steam humidifier within a preset time period. This improves the accuracy of steam supply measurement, resulting in a more accurate measurement of the humidification efficiency of the dry steam humidifier.

[0006] This invention provides a method for detecting the humidification efficiency of a dry steam humidifier, comprising the following steps: The amount of steam supplied by the steam generator to the dry steam humidifier within a preset time period is obtained; The amount of air humidified during the preset time period is detected; The humidification efficiency of the dry steam humidifier is determined based on the humidification amount and the steam amount.

[0007] The present invention also provides a humidification efficiency testing device for a dry steam humidifier, comprising the following modules: The steam quantity determination module is used to obtain the amount of steam supplied by the steam generator to the dry steam humidifier within a preset time period. The humidification amount determination module is used to detect the humidification amount of the air within the preset time period; The humidification efficiency determination module is used to determine the humidification efficiency of the dry steam humidifier based on the humidification amount and the steam amount.

[0008] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the humidification efficiency detection method of the dry steam humidifier described above.

[0009] The present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the humidification efficiency detection method for a dry steam humidifier as described above.

[0010] The present invention also provides a computer program product, including a computer program that, when executed by a processor, implements the humidification efficiency detection method for a dry steam humidifier as described above.

[0011] This invention provides a method and apparatus for detecting the humidification efficiency of a dry steam humidifier. Considering that the steam supply of a dry steam humidifier obtained under low air temperature and high humidification conditions according to the testing method specified in the national standard is inaccurate, this invention replaces the steam supply calculated by measuring the humidification amount obtained from the air side and the amount of condensate discharged by the tested humidifier with the amount of steam supplied by the steam generator to the dry steam humidifier within a preset time period. This improves the accuracy of the steam supply measurement, thereby making the measured humidification efficiency of the dry steam humidifier more accurate. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0020] The following is combined Figures 1 to 3 The present invention describes a method for detecting the humidification efficiency of a dry steam humidifier. Figure 1 This is one of the flowcharts illustrating the humidification efficiency testing method for a dry steam humidifier provided by the present invention.

[0021] To better illustrate the humidification efficiency testing method for the dry steam humidifier provided by this invention, a test apparatus equipped with a dry steam humidifier is first described. For example... Figure 2 As shown, the test apparatus 100 equipped with a dry steam humidifier includes a water tank 110, a water supply circuit 120, a steam generator 130, a steam circuit 140, a dry steam humidifier 150, and a humidifier test section 160.

[0022] The humidification efficiency detection method of the dry steam humidifier 150 provided by the present invention can be applied to the controller in the test device 100. Figure 2 (not shown in the image), or it can also be applied to electronic devices that are communicatively connected to the test apparatus 100 ( Figure 2 (Not shown in the image).

[0023] The water tank 110 stores the water required for the steam generator 130. The water supply circuit 120 serves as a water delivery channel, transporting water from the water tank 110 to the steam generator 130. The water supply circuit 120 can integrate flow rate, temperature, and other measuring devices. Figure 2 (Not shown in the image), used for subsequent monitoring and calculation of the amount of steam supplied by the steam generator 130 to the dry steam humidifier 150 within a preset time period. The steam generator 130 can be an electromagnetic steam generator. As the core steam-producing device, the steam generator 130 uses electrical energy to heat and vaporize water into steam, and delivers the steam to the dry steam humidifier 150 through the steam circuit 140. The steam circuit 140 can integrate a temperature sensor ( Figure 2 (not shown in the image) and pressure sensor ( Figure 2 (Not shown in the image) This is used to subsequently calculate the amount of steam supplied by the steam generator 130 to the dry steam humidifier 150 within a preset time period. The dry steam humidifier 150 can inject steam downstream of the duct of the humidifier test section 160. The air humidity content upstream and downstream of the duct of the humidifier test section 160 can be detected separately within the preset time period, and the humidification amount of the air within the preset time period can be determined using the air humidity difference method.

[0024] The steam generator 130 can stop evaporation after detecting that the temperature in the steam circuit 140 has reached a first preset temperature, i.e., stop outputting steam, and then restart evaporation and output steam after detecting that the temperature in the steam circuit 140 has dropped to a second preset temperature. The first and second preset temperatures can be set according to actual needs.

[0025] like Figure 1 As shown, the method for testing the humidification efficiency of this dry steam humidifier includes the following steps: Step 101: Obtain the amount of steam supplied by the steam generator to the dry steam humidifier within a preset time period.

[0026] The method for obtaining the amount of steam supplied by the steam generator to the dry steam humidifier within a preset time period includes, but is not limited to, determining the amount of steam based on data collected by sensors or data acquisition components installed in the water supply circuit or steam circuit of the test device.

[0027] The preset time period can be a unit time period or a time period of other custom lengths.

[0028] Step 102: Detect the amount of air humidification within a preset time period.

[0029] One method for detecting humidification capacity is to measure the dry-bulb and wet-bulb temperatures of the air before and after the humidifier and calculate the change in air humidity. For example, the dry-bulb and wet-bulb temperatures upstream of the air duct in the humidifier test section, as well as the dry-bulb and wet-bulb temperatures downstream of the air duct, can be measured and combined with the airflow to calculate the air humidification capacity.

[0030] Step 103: Determine the humidification efficiency of the dry steam humidifier based on the humidification amount and steam amount.

[0031] The humidification efficiency of a dry steam humidifier can be determined based on the ratio between the humidification amount and the steam amount.

[0032] In the above scheme, considering that the steam supply of the dry steam humidifier obtained according to the national standard under low air temperature and high humidification conditions is inaccurate, the present invention replaces the steam supply calculated by measuring the humidification amount obtained from the air side and the condensate amount discharged by the tested humidifier with the steam supply provided by the steam generator to the dry steam humidifier within a preset time period, thereby improving the accuracy of the steam supply measurement and making the measured humidification efficiency of the dry steam humidifier more accurate.

[0033] In one possible embodiment, obtaining the amount of steam supplied by the steam generator to the dry steam humidifier within a preset time period includes: The mass flow rate obtained by a mass flow meter installed on the steam pipeline within a preset time period is taken as the steam quantity. The steam pipeline is located between the steam output end of the steam generator and the steam input end of the dry steam humidifier. That is, a mass flow meter, which can be a Coriolis mass flow meter, can be installed on the steam pipeline. The mass flow meter's installation on the steam pipeline allows the quantity of steam supplied by the steam generator to the dry steam humidifier within the preset time period to be determined using its mass flow rate signal.

[0034] In one possible embodiment, the method for obtaining the amount of steam supplied by the steam generator to the dry steam humidifier within a preset time period may include the following steps: The system obtains the water consumption of the water supply circuit in the steam generator within a preset time period. This circuit provides water for steam generation. Based on the consumption, the amount of steam supplied by the steam generator to the dry steam humidifier within the preset time period is determined. In other words, assuming the steam generator's evaporation efficiency is close to 100%, it means that almost all the input electrical energy is used to convert water into steam, and heat loss and residual water (such as from periodic blowdown) within the steam generator can be ignored. At this point, the water entering the steam generator equals the water converted into steam plus a very small amount of residue. When the residue is infinitesimally close to zero, the consumption is approximately equal to the steam output. Therefore, the water consumption in the water supply circuit within the preset time period can be directly used as the amount of steam supplied by the steam generator to the dry steam humidifier within the preset time period.

[0035] A high-precision electronic scale or mass flow meter can be installed in the water supply circuit to obtain the water consumption of the steam generator's water supply circuit per unit time period. The water consumption of the water supply circuit can be considered as the water inflow to the steam generator.

[0036] In one possible embodiment, if the steam is saturated, the above method for obtaining the amount of steam supplied by the steam generator to the dry steam humidifier within a preset time period may include the following steps: First, obtain the difference between the saturated vapor enthalpy and the saturated water enthalpy of the steam at the output of the steam generator, and the product of the power consumption of the steam generator and the evaporation efficiency of the steam generator within the preset time period.

[0037] The difference between saturated vapor enthalpy and saturated water enthalpy is also known as latent heat of vaporization. Based on this steam pressure, the saturated water enthalpy and saturated vapor enthalpy are determined by referring to tables or other methods.

[0038] The steam temperature at the output of the steam generator can be obtained by using a temperature detection component (such as a temperature sensor) installed in the steam circuit to collect steam temperature data at multiple time points within a preset time period, and then taking the average of the temperatures collected at multiple time points as the steam temperature. Similarly, the steam pressure at the output of the steam generator can be obtained by using a pressure detection component (such as a pressure sensor) installed in the steam circuit to collect steam pressure data within a preset time period, and then taking the average of the collected pressure data as the steam pressure.

[0039] The evaporation efficiency can be the standard evaporation efficiency of the steam generator, or it can be obtained by correcting the standard evaporation efficiency based on the operating time of the steam generator. Alternatively, the evaporation efficiency can be determined based on the enthalpy difference (latent heat of vaporization) between the enthalpy of the steam output and the enthalpy of the inlet water in the previous preset time period, the consumption of the water replenishment circuit in the previous preset time period, and the power consumption. For example, the evaporation efficiency can be calculated using formula (1): Formula (1) in, This represents the evaporation efficiency, and its value can range from 0 to 1. This indicates the water consumption of the replenishment circuit in the previous preset time period (unit: kg). This indicates the enthalpy (unit: kJ / kg) of the steam output from the steam generator during the previous preset time period. This indicates the influent enthalpy (unit: kJ / kg) during the previous preset time period. This indicates the power consumption of the steam generator in the previous preset time period (unit: kJ).

[0040] Then, based on the product and the difference, the amount of steam supplied by the steam generator to the dry steam humidifier within a preset time period is determined. See formula (2) for details: Formula (2) in, This indicates the amount of steam (in kg) supplied by the steam generator to the dry steam humidifier within a preset time period. Indicates power consumption (unit: kJ). This represents saturated vapor enthalpy (unit: kJ / kg). This represents the enthalpy of saturated water (unit: kJ / kg). This represents the evaporation efficiency, and its value can range from 0 to 1.

[0041] In one possible embodiment, considering that the steam output from the steam generator may contain unvaporized water, the method for determining the amount of steam supplied by the steam generator to the dry steam humidifier within a preset time period based on consumption may include, for example: Figure 3 The following steps are shown: Step 201: Obtain the enthalpy of the steam at the output end of the steam generator, the steam temperature at the output end of the steam generator, and the steam pressure.

[0042] The enthalpy of steam can be considered as the enthalpy value per unit mass of steam at the output end of the steam generator within a preset time period. The enthalpy of steam can be obtained by: obtaining the inlet water temperature of the steam generator, and then consulting a table or formula for the thermodynamic properties of water to obtain the enthalpy (inlet water enthalpy) at that inlet water temperature, with units of kJ / kg. The inlet water temperature of the steam generator can be the average of the temperatures collected from the water in the makeup water circuit at multiple time points within the preset time period. The steam pressure at the output end of the steam generator can be the average of the pressures collected from the steam circuit at multiple time points within the preset time period. The enthalpy of steam at the output end of the steam generator can be obtained by: obtaining the power consumption of the steam generator within the preset time period, and adding the ratio between the power consumption and the power consumption to the inlet water enthalpy to obtain the enthalpy of steam at the output end of the steam generator. For example, the method for obtaining the enthalpy of steam can refer to formula (3): Formula (3) in, This indicates the enthalpy (unit: kJ / kg) of the steam output from the steam generator. This indicates the enthalpy of the incoming water (unit: kJ / kg). This indicates the water consumption of the replenishment circuit within a preset time period (unit: kg). This indicates the power consumption of the steam generator within a preset time period (unit: kJ).

[0043] Step 202: Determine the steam dryness at the output of the steam generator based on the enthalpy of the steam at the output of the steam generator, the steam temperature at the output of the steam generator, and the steam pressure.

[0044] Here, steam dryness refers to the dryness of the steam supplied to the dry steam humidifier.

[0045] In one possible embodiment, step 202 may include the following steps: First, based on the steam temperature and steam pressure at the output of the steam generator, the saturated water enthalpy and saturated vapor enthalpy corresponding to the steam at the output of the steam generator are determined. For example, the difference between the steam temperature and the saturation temperature at the given steam pressure can be determined to be less than or equal to a preset difference; if so, it indicates that the steam is in a saturated state. Once it is determined that the steam is in a saturated state, the saturated water enthalpy and saturated vapor enthalpy are determined based on the steam pressure using methods such as looking up a table.

[0046] Next, obtain the first difference between the enthalpy of steam and the enthalpy of saturated water, and the second difference between the enthalpy of saturated steam and the enthalpy of saturated water. That is, the first difference = enthalpy of steam - enthalpy of saturated water. The second difference = enthalpy of saturated steam - enthalpy of saturated water.

[0047] Then, the ratio between the first difference and the second difference is taken as the steam dryness fraction. For example, steam dryness fraction = first difference / second difference. The method for determining steam dryness fraction can be found in formula (4): Formula (4) in, This indicates the dryness of the steam, and its value can range from 0 to 1. Enthalpy of steam (unit: kJ / kg) This represents the enthalpy of saturated water (unit: kJ / kg). This represents saturated vapor enthalpy (unit: kJ / kg).

[0048] Step 203: The product of consumption and steam dryness is used as the amount of steam supplied by the steam generator to the dry steam humidifier within a preset time period.

[0049] In other words, the amount of steam supplied by the steam generator to the dry steam humidifier = consumption × steam dryness.

[0050] In one possible embodiment, step 103 may include the following steps: obtaining the ratio between the humidification amount and the steam amount; and using the ratio as the humidification efficiency of the dry steam humidifier.

[0051] For example, humidification efficiency = (humidification amount / steam amount) × 100%.

[0052] The above solution eliminates the need to measure the condensate discharged from the humidifier under test, reducing the problem of inflated efficiency caused by the failure to account for secondary condensation in the air duct. This significantly improves the accuracy and reliability of dry steam humidifier efficiency testing under low air temperature and high humidification conditions.
