Title: | Feasibility investigation of the low energy consumption cooling mode with ground heat exchanger and terminal radiator | Authors: | Man, Y Yang, H Qu, Y Fang, Z |
Issue Date: | 2015 | Source: | Procedia engineering, 2015, v. 121, p. 423-429 | Abstract: | Due to its huge heat capacity, ground can provide heat source in winter and heat sink in summer as the so called shallow geothermal energy, which is mainly utilized by the ground coupled heat pump system. In fact, free cooling can be provided by circulating water between the ground heat exchanger (GHE) and the indoor terminal directly. Recently, radiator for cooling developed rapidly due to it possesses high energy efficiency and comfortable level, however, condensation arises if entering water temperature is lower than dew point of the ambient air. Therefore, this study proposes a low energy consumption cooling mode by combining the GHE and the terminal radiator to utilize the ground cooling directly and to prevent the condensation problem of terminal radiator. The simulation model of this novel mode is established, and the feasibility of this low energy consumption cooling mode is analyzed based on simulation results. | Keywords: | Cooling mode Ground heat exchanger Low energy consumption Terminal radiator |
