[0031] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0032] Please refer to Figure 1 A method for measuring the cooling and heating energy consumption of a dehumidifier comprises the following steps:

[0033] S1. Acquisition of air volume data, temperature data and relative humidity data based on the equipment on the processing wind side and the regeneration wind side;

[0034] S2. Calculate the air enthalpy value at the air inlet and the air enthalpy value at the air outlet of the front surface cooling based on the temperature data and the relative humidity data;

[0035] S3, calculating the cooling capacity of the front surface cooling according to the air volume data and the air enthalpy value of the air at the air inlet and the air enthalpy value of the air at the air outlet;

[0036] According to the air volume data and temperature data, the cooling capacity of the middle surface cooling and the rear surface cooling, as well as the heat of the first-stage regenerative heater and the second-stage regenerative heater are calculated.

[0037] From the above description, it can be seen that the beneficial effects of the present invention are: a dehumidifier cold and hot energy consumption metering method of the present invention, by processing the equipment on the wind side and the regeneration air side, comprehensively obtains the air volume, temperature and relative humidity data, and respectively calculates the cooling capacity of the front surface cooling, the middle surface cooling, the rear surface cooling and the heat of the first-level regeneration heater and the second-level regeneration heater, which can clearly understand the energy consumption of each component, help to find the links with higher energy consumption, and provide a clear direction for energy-saving optimization.

[0038] Furthermore, the calculation of the inlet air enthalpy value and the outlet air enthalpy value of the front surface cooling in step S2 is specifically as follows:

[0039] Calculate the inlet air enthalpy value based on the temperature data and relative humidity data of the front cold air inlet;

[0040] Calculate the outlet air enthalpy value based on the temperature data and relative humidity data of the cold air outlet of the front table;

[0041] The calculation formula of the air enthalpy value is expressed as:

[0042]

[0043] Among them, h represents the air enthalpy value, T represents the temperature data, and ψ represents the humidity data.

[0044] From the above description, it can be seen that taking into account the latent heat change of the front surface cooling, the cooling capacity of the front surface cooling is calculated in combination with the air enthalpy value, and the specific calculation of the air enthalpy value is clarified, which provides a solid foundation for the subsequent accurate calculation of the cooling capacity of the front surface cooling.

[0045] Further, the air volume data includes fresh air volume;

[0046] The specific calculation of the cooling capacity of the front table is:

[0047]

[0048] Among them, Q 冷 represents cooling capacity, ρ represents air density, G 新 represents the fresh air volume, h1 represents the inlet air enthalpy, and h2 represents the outlet air enthalpy.

[0049] From the above description, we can know that the specific calculation formula of the front-end cooling capacity is clarified, and the cooling capacity is calculated using the fresh air volume, air density, and the difference in enthalpy between the inlet and outlet air. This makes the calculation of the front-end cooling capacity more accurate and standardized, and can accurately reflect the cooling capacity consumption of the front-end cooling during actual operation, which helps to analyze the energy consumption distribution of each component of the dehumidifier in more detail and provide more targeted data support for energy-saving improvements.

[0050] Furthermore, the fresh air volume is obtained specifically as follows:

[0051] Obtain fresh air volume by replacing the traditional fan with a fresh air EC wind wall at the fresh air inlet;

[0052] The fresh air EC wind wall is composed of a plurality of EC fans, and the fresh air volume is obtained as follows:

[0053] G 新 =G1+G2+....G n ;

[0054] Among them, G1~G n They respectively represent the air volumes of the 1st to nth EC fans constituting the fresh air EC wind wall.

[0055] From the above description, it can be seen that the method of obtaining the fresh air volume is explained in detail, and the fresh air volume is obtained through the fresh air EC wind wall, and it is clear that the fresh air EC wind wall is composed of a number of EC fans, and the fresh air volume is the sum of the air volumes of each EC fan. This method makes the acquisition of fresh air volume more accurate and quantifiable. At the same time, the combination of EC fans facilitates the flexible adjustment of fresh air volume according to actual needs, improves the adaptability of the dehumidifier to different working conditions, and also provides reliable air volume data for accurate calculation of the front table cooling capacity.

[0056] Further, the air volume data includes the air volume of the middle surface cooling air volume, the rear surface cooling air volume, the rear rotor regeneration air volume and the front rotor regeneration air volume;

[0057] The calculation of the cooling capacity of the middle surface cooling and the rear surface cooling, and the heat of the first-stage regeneration heater and the second-stage regeneration heater is specifically as follows:

[0058]

[0059] Among them, Q cold / hot represents the amount of cold or heat, and ρ represents the air density;

[0060] When calculating the cooling capacity of the surface cooling:

[0061] ΔT = T2 - T1;

[0062] G=G 中表 ;

[0063] Among them, G 中表 It indicates the cooling air volume of the middle table, T2 indicates the outlet dry bulb temperature of the middle table cooling air, and T1 indicates the inlet dry bulb temperature of the middle table cooling air;

[0064] When calculating the cooling capacity of the rear surface cooling:

[0066] G=G 送风 ;

[0067] Among them, G 送风 It indicates the cooling air volume of the rear surface, T4 indicates the outlet dry bulb temperature of the cooling air of the rear surface, and T3 indicates the inlet dry bulb temperature of the cooling air of the rear surface;

[0068] When calculating the heat of the primary regenerative heater:

[0069] ΔT = T2 - T1;

[0070] G=G 再生1 ;

[0071] Among them, G 再生1 represents the regeneration air volume of the rear rotor, T6 represents the dry bulb temperature after heating by the first-stage regeneration heater, and T5 represents the dry bulb temperature before heating by the first-stage regeneration heater;

[0072] When calculating the heat of the secondary regenerative heater:

[0073] ΔT = T8 - T7;

[0074] G=G 再生2 ;

[0075] Among them, G 再生2 It indicates the front impeller regeneration air volume, T8 indicates the dry bulb temperature after heating by the secondary regeneration heater, and T7 indicates the dry bulb temperature before heating by the secondary regeneration heater.

[0076] From the above description, we can see that the specific calculation formulas for the cooling capacity of the middle and rear surfaces and the heat of the first and second regenerative heaters are clarified. For different components, the energy consumption is calculated according to their corresponding air volume and temperature difference, making the energy consumption calculation of each component more accurate and standardized. Being able to clearly understand the energy consumption of each component helps to find the links with high energy consumption and provide detailed energy consumption data for energy-saving optimization and operation management of the dehumidifier.

[0077] Furthermore, the middle surface cold air volume is obtained through the EC air supply wall arranged after the outlet and return air mixing section in the front wheel processing area;

[0078] The air supply EC wind wall is composed of a plurality of EC fans, and the air volume of the intermediate cooling is obtained as follows:

[0079] G 中表 =G1+G2+....G n ;

[0080] Among them, G1~G n They respectively represent the air volumes of the 1st to nth EC fans constituting the air supply EC wind wall.

[0081] As can be seen from the above description, the method of obtaining the middle cooling air volume is described in detail, which is obtained through the air supply EC wind wall, and the air supply EC wind wall is composed of several EC fans. The middle cooling air volume is the sum of the air volumes of each EC fan. This acquisition method makes the measurement of the middle cooling air volume more accurate. At the same time, the EC fan combination is convenient for adjusting the air volume to meet the operation requirements of the middle cooling under different working conditions, providing reliable air volume data for accurately calculating the cooling capacity of the middle cooling.

[0082] Further, the rear rotor regeneration air volume is obtained by a first-stage regeneration EC fan arranged after the rear rotor regeneration zone;

[0083] The front rotor regeneration air volume is obtained by a secondary regeneration EC fan arranged after the front rotor regeneration zone.

[0084] From the above description, it can be seen that the regeneration air volume of the rear rotor and the regeneration air volume of the front rotor are obtained through the first-level regeneration EC fan and the second-level regeneration EC fan respectively, which ensures the accuracy of the regeneration air volume data and provides a reliable air volume basis for accurately calculating the heat of the first-level regeneration heater and the second-level regeneration heater, which helps to optimize the rotor regeneration process and improve the overall operating efficiency of the dehumidifier.

[0085] Furthermore, the air volume of the rear surface cooling is calculated based on the air volume of the middle surface cooling and the air volume of the first-stage regeneration fan.

[0086] From the above description, it can be seen that the calculation method of the rear cooling air volume is based on the middle cooling air volume and the air volume of the first-level regeneration fan. This calculation method makes reasonable use of the existing air volume data, avoids additional measurement equipment and complex measurement process, simplifies the acquisition process of the rear cooling air volume, and ensures the accuracy of the rear cooling air volume data, which provides convenience for accurately calculating the cooling capacity of the rear cooling.

This structural design is flexible and adjustable. It can flexibly adjust the fresh air volume and the intermediate surface cooling air volume by adjusting the operating status of the EC fan according to the actual dehumidification needs and working conditions. This enables the dehumidifier to better adapt to different environmental conditions and load requirements, thereby improving the operating efficiency and energy-saving effect of the dehumidifier.
