严寒地区空气——土壤双热源热泵能耗分析 在严寒地区，供暖是居民生活中最为关键的问题之一。传统的供暖方式通常使用锅炉和其他热能设备，但这些设备的能耗非常高，而且环保性也很差。为了解决这一问题，近年来全球许多地区都开始使用土壤双热源热泵系统来提供供暖。本文将对该系统的能耗进行分析。 SoilSourceHeatPumpSystem Soilsourceheatpumpsystemisahighlyefficientheatingsystemthattakesadvantageofthenaturalheatoftheearthtoprovideheatingforbuildings.Thesystemconsistsofaheatpumpunit,agroundloop,adistributionsystem,andacontrolunit.Groundloopsarepipesthatareburiedunderground,andtheheatpumpunitisresponsibleforextractingheatfromthegroundanddistributingittothebuilding.Theefficiencyofthesystemisdeterminedbytheheattransferrateoftheheatpumpunitandthetemperaturedifferencebetweentheheatsourceandthebuilding.
