IIR documentSummary
The heat discharged into the soil by ground-coupled heat pump system in summer is much larger than that absorbed from soil in winter, which will seriously influence the temperature field in the soil in some instance. This paper presents the ground-coupled heat pump with condensing heat recovery system which can balance the heat discharge and absorption. The optimal model of the ground-coupled heat pump with condensing heat recovery system is set up according to the exergy balance theory. Based on the model, the refrigeration circulation process is analyzed under the different condensing heat load, the optimal arrangement and sizes of chillers achieved. An example of ground-coupled heat pump system with condensing heat recovery system is presented, in which the model is applied to get higher special exergy efficiency and condensing heat recovery efficiency.
