Buildings represent a large part in terms of fossil energy consumption, which depends on the great need for heating. Even if the solar absorption heat storage system is possible, the performance of this system is affected by the cycle limits and the climatic conditions. The goal of the present study is to control the thermal performance of the system cycle according to the imposed climatic conditions of Bucharest city, Romania, and therefore a numerical model was developed for this purpose. The scheme and the thermodynamic cycle, the energy and mass balance equations, and the computational algorithm were presented. The results show that the cycle temperature increases at the end of desorption when the heating power supplied to the desorber is increased, which is also proportional to the drop in temperature at the beginning of the desorption. The temperature at the end of absorption and the mass flow rates of the solution have a significant effect on the thermal power released from the absorber and used to heat the building. For an average daily heat power of 1.35 kW/m² and 10 hours per day of heating the building, the system with a solar collector area of 3 m² has the capacity of heat supply for all the cold period. However, an economic strategy remains necessary.

在化石能源消耗方面，建筑物占很大一部分，这取决于对供暖的巨大需求。即使有可能采用太阳能吸收式储热系统，该系统的性能也会受到循环极限和气候条件的影响。本研究的目的是根据所施加的罗马尼亚布加勒斯特市的气候条件来控制系统循环的热性能，因此为此目的开发了一个数值模型。给出了方案和热力学循环，能量和质量平衡方程以及计算算法。结果表明，当提供给解吸器的加热功率增加时，循环温度在解吸结束时增加，这也与解吸开始时的温度下降成比例。吸收结束时的温度和溶液的质量流速对从吸收器释放并用于加热建筑物的热能产生重大影响。平均每日热功率为1.35 kW / m每天为建筑物供暖²到10个小时，太阳能集热器面积为3 m ²的系统在整个寒冷时期都具有供热能力。但是，经济战略仍然是必要的。
