Design And Application Of Ground Source Heat Pump System Heat Exchanger

Underground’s covering up to take care of circuitry progress design link is technical soil source heat pump nucleus and important application foundation, the soil source heat pump underground’s covering up to take care of transmitting heat of circuitry is one to full complicated of the non-steady state transmit heat process.On the other hand:Change a covering up of thermal machine tube method, soil characteristic, underground hydrology parameter, return to fill material and weather parameters in the ground to all effect to change thermal a transmitting heat of machine process;On the other hand:Earth covers up a tube to transmit heat process again and heat pump machine in the ground of the run-time characteristic Be mutual to effect.But accurate measure the hot thing parameter of underground soil is underground cover up the point of taking care of the circuitry design, therefore accurate measurement soil thermal the thing is count for much for the design operate of earth source heat pump system.Introduced the working principle of ground source heat pump system, hope to make designer understand operation mode of the system. Meanwhile introduces the classification of buried pipe way, comparison show respective technical characteristics of vertical and horizontal ground loop, for the selection of buried pipe way provided some help. By the further analysis of buried pipe way, the paper studies the buried pipe spacing. Discusses the soil thermal physical characteristics, operation mode and buried pipe layout to bury pipe space effect. Based on experimental research and simple economic analysis,this paper puts forward a preliminarily determined buried pipe spacing method.Mainly analyzed geology structure and geology temperature change law, change from the underground thermal the machine transmit heat the theory search of process to set out and analyze inside the underground drilling, outside of transmit heat process, and pass computing the unit well deeply change heat energy force.(postpone a rice to change calorific value)Transmit heat a condition according to the different flow rate and the tube diameter, computing an actinium Ling region to quite the cheesely cover up to take care of spacing and flow rate inside the tube, provide a fair reference value for the reasonable design of soil source heat pump system, make a source heat pump, this new technique able to against time receive application and generalize.
