The performance of the second type solar heat pump (heat exchanger) driven by solar energy was numerically simulated, and the mathematic model of solar thermal collector and the mathematical model of each component of the second type absorption heat pump system were established. (Lithium bromide solution) physical properties of the calculation process.Under the conditions of variable conditions for the second type of absorption heat pump performance simulation study by solving the nonlinear equations, obtained in different external ambient temperature and different absorption temperature, The occurrence of temperature and other conditions under the second absorption heat pump system performance changes
