Abstract


In this paper, the current global energy crisis and the northern city of winter heating energy consumption big problem, taking into account the status quo of solar energy resources in most parts of China , proposed the use of solar collectors and heat pump technology to a combination of new heating mode . By testing laboratory seat of the amount of solar radiation and temperature changes , the use of solar heating is basically to meet the thermal needs of users . However, due to solar inherent dispersed , random and intermittent problems , so the solar heat pump heating system coupled air-source heat pumps and water source heat pump system with auxiliary heat source trough energy to cope in extreme weather heating problems , while also introduced a patented heat pump - with ejector refrigeration cycle solar heat pump system , and its modeled on a novel solar -assisted heat pump heating system with ejector . Ambient temperature air source heat pump heating capacity in multi- source heat pump heating systems have a great impact , this paper using MATLAB software for mathematical simulation of the impact of imports of the temperature of the air source heat pump heating capacity ; water source heat pump water as the water temperature in the low temperature heat source , heat storage in the accumulator has a great influence on the water source heat pump heating capacity , this paper also analyzes the inlet water temperature for water source heat pump . According to the results found in the combination of solar thermal technology and heat pump technology to improve solar energy utilization and the efficiency of the heat pump system has been greatly improved . The results show that after the optimization is performed in the integration of the system and the automatic control , solar heat pump system can be solved weather heating problems . Development and use of solar energy resources is very beneficial and necessary , the solar heat pump heating system is not suitable for non- central heating ordinary residents and towns , and rural users , not only the effective use of energy but also in response to the sustainable development of China has been advocating called on .
