[Abstract]:China is in the rapid development stage, energy consumption has been the focus of attention. In recent years, building energy consumption has increased year by year, among which air conditioning energy consumption accounts for the largest proportion. In order to establish a resource-conserving and environment-friendly society, a new method of indirect evaporative cooling with natural cold source instead of artificial cold source, an environmentally friendly, efficient and economical cooling technology, has been forced us to study green air conditioning. According to the conditions of the existing test bench, combined with the continental climate of the warm temperate zone in Zhengzhou, Rain Water is relatively few and dry, the indirect evaporative cooling technology of folding plate type and circular tube type is studied. Several parameters are simulated and tested, and the data are analyzed, and the indirect evaporative cooling efficiency of folded plate type and circular tube type is obtained under the condition of the same test bench. The parameter selection range to maintain the optimal efficiency and the performance of the two types of coolers are analyzed and compared. Through the analysis of experimental data and the field measurement, two kinds of practical engineering recommended values are given, which can provide reference for the selection of air conditioning form in the future. The specific contents of this research are as follows: (1) to study the development of indirect evaporative cooling technology at home and abroad, to understand the cooling equipment with different structures, to master the theoretical knowledge and the method of thermal calculation. This paper provides a simple and effective calculation method for the test and analysis of the experimental results. According to the relevant theoretical knowledge of the existing evaporative cooling technology of folded plate and circular tube, the comprehensive test bench is optimized for ventilation adjustment. Uniform layout of test points, reasonable sealing of the inlet to meet different structural forms, ensuring reasonable airflow organization. (3) brief introduction of the various systems and different functional sections of the test bench, Then the two types of coolers are measured at the same time, and the parameters such as variable wind speed and water injection amount are adjusted reasonably, the data are recorded and sorted out under different working conditions, and the heat transfer efficiency of the two kinds of equipment is analyzed and calculated. The influence trend of each parameter on the efficiency and the comparative analysis of the performance of the two kinds of coolers are obtained, and the optimal range of the efficiency parameters of the two types of coolers is obtained. The influencing factors are as follows: (1) the performance of the two coolers is studied and the selection range of the parameters in the actual engineering is given. The actual operation efficiency and energy saving of the coolers in the actual operation of an air conditioning project in a textile mill are introduced. Through the research of this subject, the energy saving effect of different forms of indirect evaporative cooler can be obtained. Combined with the actual situation of the project, the influence of various factors on the operation efficiency of the equipment can be considered synthetically, which can provide the basis for the choice of the air conditioning form in the industrial workshop.
