Application Analysis of the BCHP System with the Soil Source Absorption Heat Pump Driven by the Flue Gas

Abstract:

How to use the waste heat deeply are a critical issue for BCHP (Building combined cooling heating and power) system. A BCHP system with a soil source absorption heat pump driven by the waste heat is proposed. The system is composed of an internal combustion engine, a soil source absorption heat pump driven by the flue gas, and other assistant facilities, such as pumps, fans, and end user devices. In the winter, the flue gas is used to drive absorption heat pump to recover the waste heat of the soil source and the condensation heat of the flue gas simultaneously, and in the summer, the waste heat of the flue gas is used to drive absorption heat pump to cooling, and the heat sink is the soil. In the paper, the configuration of this kind of system is designed, and the energy analysis of the system is done all the year. Compared with the conventional BCHP system, the operation cost is lowered greatly and the increased investment could be returned within one year. It is show that the system is the efficient integration of cleaning energy, renewable energy, the discharge of the flue gas could be reduced to below 30°C, and the water steam could be catch to avoid the white smoke of the stack. The energy saving in space heating could be 66% compared with the conventional BCHP systems.
