Study on the physical clogging of water source heat pump (WSHP) in recharge
and based on the mass balance equation to establish the mathematical model of transport and deposition of particulates. The suspended particle’s concentration dynamic changes with time and bring into the two variable quantity of and are introduced
and the size exclusion effect in model is considered fully. The occurrence of clogging is often caused by a particle that one particle plug a pore
and vice versa. The results of theoretical of the physical clogging of WSHP in recharge would directly bring into experiment research.
