摘要:地源热泵技术属可再生能源利用技术。地源热泵是利用了地球表面浅层地热资源作为冷热源,进行能量转换的供暖空调系统。地表浅层地热资源可以称之为地能,是指地表土壤、地下水或河流、湖泊中吸收太阳能、地热能而蕴藏的低温位热能。它不受地域、资源等限制,真正是量大面广、无处不在。这种储存于地表浅层近乎无限的可再生能源,使得地能也成为清洁的可再生能源一种形式。
设计内容部分:
本设计为天津市碧江名苑地源热泵空调系统及地板辐射采暖系统设计。首先,确定该建筑内空调房间的室内外计算参数;其次,确定各空调房间的冷负荷、湿负荷和热负荷;然后对别墅空调系统进行设计,其中包括系统的选择和确定送风管,送回风形式的选择,送风量和送风状态的计算,新风量的计算,空调机组的选型,管材的选择、风管和水管的布置以及水力计算。再次,计算冬夏季地下换热量,确定地源埋管的换热量,来设计地下换热器和地源热泵空调机组的选择。然后再进行地板辐射采暖的设计,先计算供暖热负荷,再确定地板采暖敷设方式,接着计算管间距。最后,进行消声减震设计。

Abstract:Ground source heat pump technology is the use of renewable energy technology. Ground source heat pump is the use of the earth's surface shallow layer geothermal resources as the cold and heat source, energy conversion of the heating and air conditioning system. Shallow layer geothermal resources can be called to, refers to the surface soil, groundwater or rivers, lakes to absorb solar energy, geothermal energy and contain the low level heat energy. It is not subject to geographical, resource limitations, really is a quantity bedding face is wide, everywhere. This is stored in the shallow layer almost infinitely renewable energy, which can become clean and renewable energy form.
design elements:
this ground source heat pump item is designed for Bi Jiang Ming Yuan Tian Jin.First, determine the building inside the air conditioned room indoor and outdoor calculation parameters; secondly, to determine the air conditioning room cooling load, wet load and thermal load; then the villa air-conditioning system design, including the system of selection and the identification of blast pipe, air supply and return form selection, air volume and air supply state calculations, the calculation of fresh air, return air quantity calculation of air conditioning units, air handling and selection, the selection of pipe material, pipe and pipe layout and hydraulic calculation. Again, calculation of underground heat in winter and summer, determine the heat pipe heat exchanger, to the design of ground heat exchanger of ground source heat pump air conditioning unit selection and. Then radiant floor heating design, the first heating load calculation, and then determine the floor heating installation, then calculate the tube spacing. Finally, for damping design.
