Energetic and Exergetic Performances Simulating of GSHP Greenhouse Cooling System in Northern China

Résumé

The Energetic and Exergetic performances evaluating models were built for a agricultural greenhouse cooling with groundwater-style GSHP system (GSHPs) in Northern China. The Exergy destruction (Exdest), Exergy efficiency(ε) and coefficient of performance (COP) were estimated and presented based on summer cooling test monitored data and the simulation models. Analyzed results indicate that the evaporator has the highest Exergy efficiency compared with other sections of the system, which reached 92% during cooling test that means the evaporator has a brilliant performance of reversibility in cooling mode. The condenser and compressors have lower reversibility relatively. Generally, GSHPs has an Exergy efficiency of 36%. Besides, COP of GSHPs cooling in greenhouse reached 3.09, which is higher than 2.0 of conventional air source heat pump systems COP by 50%.
