Research Of Underground Storage And Directly Cooling Technology In Villages

In the current background of energy shortage and environmental pressures increasing year by year, our country put forward the major historic task to construct new socialist villages, which is very important is to improve the living conditions of farmers. Based on the new rural construction projects of national "11th Five-Year Plan", this article is to find an energy-saving, environmental friendly method to use in the rural buildings. In this article we put forward using small ground-source heat pump systems to solve the problem of heating and air-conditioning in rural areas, and develop heat pump systems that suit the type of rural construction and the economic conditions of farmers, and analyze the feasibility, economic and the operation of the heat pump units of using three different types of ground-source heat pump in the rural areas;And then in the article we calculate the energy changing between the double-U-tube and the soil. At the same time, we analyze and compare the energy consumption of ground-source heat pump systems.In this article we make an experiment to find the water storage capacity of the well, and the results show that when the water continues flowing into the well in a setting flow, the water level will achieve the well-balanced point. It illustrate that we can use the different recharge well technology in ground-source heat pump system in single-house or several houses. At the same time, we test the energy storage capacity of the underground well, and the results show that the idea to flow energy into the underground soil is entirely feasible, and therefore we can use the seasonal energy storage technologies to balance the underground temperature changes caused by the difference between the heat duty in winter and the refrigeration duty in summer.In this article, we design the ground-source heat pump air-conditioning systems according to the economic conditions and the features of the buildings in rural areas. We use the new refrigerating medium R290 in heat pump units, that will increase the coefficient of the units and rule out the greenhouse effect and the ozone breaking caused by freon refrigerating medium. And we use centralized wide air system in the indoor part, then we just can see handsome air outlets in the house, so the economical efficiency, practicability and complexion of the systems would be all improved. Also we put forward the idea of using the same water supply well and the recharge well in several houses'ground-source heat pumps. This method is expected to completely solve the imbalance of the geothermal energy during the running of the heat pumps, and is expected to greatly reduce project costsIn the article, we use the FLUENT software to calculate the underground temperature changes during the operation of the ground-coupled heat pump systems in a simple simulation, and then analyze the scope of the underground temperature field affected by the double-U-tube and the rule of the underground temperature changes during the operation of the heat pump systems.In the final we use the BIN method to calculate the operating duty of the two constructions in the project, and then calculate and analyze the energy consumption of the heat pump systems according to the real-time energy efficiency ratio of the heat pump units in a year. We make a graph to analyze the energy consuming of the heat pump systems in various outdoor temperature, and find that in Tianjin the energy is mainly consumed in winter every year, so if we want to save energy in construction, we can focus on achieving energy-saving departure in winter.
