Heat Transfer Modeling of the Ground Heat Exchangers for the Ground-Coupled Heat Pump Systems
Ground-coupled heat pump (GCHP) systems have been gaining increasing popularity for space air conditioning in buildings due to their reduced energy and maintenance costs. The efficiency of GCHP systems is inherently higher than that of the traditional options because it utilizes the ground which maintains a relatively stable temperature all the year round as a heat source/sink. Compared with tr...
متن کاملnumerical simulation of a horizontal ground-coupled heat pump
this study represents effect of four variables in performance of a heat-pump in two cities of tehran and rasht. a computer program has been developed, simulating a certain heat pump acting in different environments with different refrigerants in heating season. the analysis is based on a homogeneous model. effect of different refrigerants, depth of the buried heat exchangers and moisture conten...
متن کاملA model of groundwater seepage and heat transfer for single-well ground source heat pump systems
In China, for the limitation of land, many buildings intending to utilize ground source heat pump systems install “single-well” systems, which drill only one well for both the pumping and reinjection of the groundwater. A model of groundwater seepage and heat transfer for single-well ground source heat pump systems has been established and validated against the experiment conducted in Denmark. ...
متن کاملthe influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
Influence of Ground Heat Exchanger Modelling on the Predicted Efficiency of the Heat Pump System
This paper presents simulations of the integral coefficients of performance of a heat pump system coupled with a vertical ground heat exchanger (GHE). The GHE is simulated using different assumptions concerning the heat transfer in the ground, heat exchange between the ground and the brine and vertical variation of the brine temperature. The differences in the predicted performance coefficients...
