The main form of ground source heat pump is rock-soil source heat pump system. To find out the causes for the poor operation effect of the system when applied in karst area, the heat transfer test and engineering research are conducted. It is considered th...
However, limitations such as a self-discharge rate (>1 %) and capacity loss (∼20 %) restrict their use for long-duration energy storage. Hydrogen, as a potential energy carrier, is suitable for large-scale, long-duration energy storage due to its high energy density, steady ...
For this invention, the liquid CO2can be fed concurrently with the biomass prior to heating unit operations. Nominally, it would be fed to the system via a different high-pressure pump than is used to pump the biomass and the pressurized biomass and pressurized CO2would be fed into a single...
For the initial boundary conditions, full constraints were applied on the lower end of the cylinder, the overall cabin was axially free, and the radial displacement constraints were applied on the top center. The material 35CrNi3MoVR with an elastic modulus of 200 GPa, tensile strength of ...
Among the many techniques for obtaining heat and electricity, solar thermal collectors, photovoltaic (PV) technology and PV/thermal (PV/T) technology have a very important place. The PV/T collectors enable the simultaneous conversion of solar radiation i
Energy-saving air-conditioner with hot water is an air source heat pump air-conditioner,which can also supply hot water.The hot water is heated by a double... JB Chen,D Chen,LU Ying - 《湖南大学学报(自然科学版)》 被引量: 0发表: 2009年 Innovative technologies in the buildings for the...
Medical gases are pharmaceutical molecules which offer solutions to a wide array of medical needs. This can range from use in burn and stroke victims to hypoxia therapy in children. More specifically however, gases such as oxygen, helium, xenon, and hydr
into the network structures that make a large amount of free water into irreducible water, thereby forming a non-Newtonian liquid-type thixotropic gel. Bentonite can improve the water retention and stability of the grouts. Therefore, bentonite is beneficial to the grouts for sealing groundwater ...
Although polymers are the typical starting materials for fibre production, ceramics, metals, or composites may also be used [150]. 2.1.3. Electrophoretic deposition Electrophoretic deposition (EPD) is a simple process that is used to produce coatings, films, or free-standing bodies [151]. It ...
