Abstract

The invention discloses a kriging model-based optimization method of an air-source heat-pump water-heater condenser tube. The method is characterized by including the following steps: (1) utilizing aparametric modeling function of AutoCAD software to construct a group of physical models of different condenser-tube diameters; (2) utilizing the parametric modeling function of the AutoCAD software to establish a group of physical models of different condenser-tube locations; (3) utilizing a fluid-field and thermal-field coupling method of COMSOL Multiphysics software to calculate temperature field distribution of the two groups of physical models; (4) determining that two obtained groups of data are sample points, and utilizing a Kriging model to carry out optimization calculation on the sample points; and (5) finally obtaining optimal condenser-tube structure parameters. The method has the advantages that the kriging model-based optimization method of the air-source heat-pump water-heater condenser tube is provided, temperature distribution inside a water tank is enabled to be most uniform through carrying out optimization design for a diameter and a location of the condenser tube,and temperature is enabled to be highest.

Description

technical field [0001] The invention relates to the structural design of the condensation pipe of the air source heat pump water heater, in particular to an optimization method for the condensation pipe of the air source heat pump water heater based on the Kriging model. Background technique [0002] Energy is the material basis of human activities. In a sense, the development of human society is inseparable from the emergence of high-quality energy and the use of advanced energy technologies. The air source heat pump water heater uses the energy change of the medium in the process of physical state change to convert air energy into heat energy. Compared with traditional solar water heaters, it only needs to consume a quarter or less of electricity to generate the same heat, and it has the characteristics of high efficiency and energy saving. [0003] The condenser is an important structure to realize the energy change of the medium, and it is also an important basis for e...
