Compared to conventional ground heat exchangers that require a separate pump or othermechanical devices to circulate the heat transfer fluid, ground coupled thermosiphons or naturallycirculating ground heat exchangers do not require additional equipm

A new avenue in modern heat pump technology is related to the use of natural refrigerants such as carbon dioxide (CO2). The use of CO2 in direct expansion ground source heat pumps (DX-GSHP) has also gained significant interest as it offers opportunit

CO2 is a promising candidate for replacing synthetic refrigerants used in direct-expansion ground-source heat pumps (DX-GSHPs). The present paper, as the first part of two, presents a numerical performance comparison of a vertical single U-pipe direc

In direct expansion ground coupled heat pumps (DX-GCHPs), the borehole heat exchanger (BHE) plays a major role, as it is the component where heat transfer between the ground coupled heat pump (GCHP...

A transient coupled model for a variable speed CO2 direct expansion ground source heat pump (DX-GSHP) is developed. An annual simulation for integrated space heating and cooling of a small residential building located in a Canadian climate is conduct
