AB - In order to understand the multi-objective particle swarm optimization  algorithm for data collection and system characteristics research of heat  pump water heaters, the author proposes a multi-objective particle swarm  optimization algorithm for data collection and system characteristics  research of phase change thermal storage heat pump water heaters. The  author first introduced the working principle of the phase change heat  storage heat pump water heater, and then conducted a comparative  experimental study on the performance of two types of heat pump water heater  systems using pure paraffin phase change heat storage and water storage.  They compared and analyzed the heat storage process, condensation heat  recovery rate of the heat storage box, and comprehensive energy efficiency  coefficient of the system under the refrigeration and heat recovery mode of  the two types of heat pump water heater systems, on this basis, measures  were proposed to improve the performance of pure paraffin phase change  thermal storage hot water systems. At long last, the examination of  exploratory information shows that the Rx of the water warm capacity  framework is around 6% higher than that of the stage change warm capacity  framework, and the framework COPt is likewise 20% higher than that of the  stage change warm capacity framework, from this, it tends to be seen that  the stage change heat capacity box has unfortunate intensity move  proficiency, prompting a lessening in the presentation of the intensity  siphon water radiator framework. Contrasted and customary water stockpiling  heat siphon boiling water frameworks, unadulterated paraffin stage change  capacity heat siphon high temp water frameworks lessen the volume of the  intensity stockpiling tank, and the framework works somewhat flawlessly  during the intensity stockpiling process. However, the system's overall  energy efficiency is impacted by the heat storage tank's poor heat exchange  effect and relatively low condensation heat recovery rate. The intensity  move of the intensity stockpiling box can be upgraded by finning the winding  curls in the intensity stockpiling box, embedding aluminum foil, adding  extended graphite, and different measures to further develop the buildup  heat recuperation rate, subsequently working on the general execution of the  framework.
