SOLAR AIR-SOURCE HEAT PUMP HOT WATER UNIT CONTROL SYSTEM DESIGN

This article introduces the principle of a solar air-source heat pump water heater system, and using a hotel in Tianjin as the research object to the dynamic characteristics of the actual operation is based on the establishment of a focus on maximizing the use of solar hot water system and improve the system integrated energy efficiency energy saving control method then using the BP neural network model to establish a system of solar collectors, as well as according to the formula derived and established a model of air source heat pump collectors through a series of experiments to verify the accuracy and feasibility of the model and proposed the control scheme predictions for the system in the future promote the use of energy provides a theoretical guidance.
