地热能的工作原理及优缺点

地源热泵是一种利用地下浅层地热资源既能供热又能制冷的高效节能环保型空调系统。地源热泵通过输入少量的高品位能源(电能),即可实现能量从低温热源向高温热源的转移。

Ground source heat pump (ground source heat pump) is an efficient and environment-friendly air conditioning system, which can make use of shallow underground geothermal resources, which can both heat and refrigerate. The ground source heat pump can transfer the energy from the low temperature heat source to the high temperature heat source through the input of a small amount of high grade energy (electric energy).

冬季制热

Heating in winter

在制热状态下,地源热泵机组内的压缩机对冷媒做功,并通过四通阀将冷媒流动方向换向。由地下的水路循环吸收地下水或土壤里的热量,通过冷媒/水热交换器内冷媒的蒸发,将水路循环中的热量吸收至冷媒中,在冷媒循环的同时再通过冷媒/空气热交换器内冷媒的冷凝,由空气循环将冷媒所携带的热量吸收。在地下的热量不断转移至室内的过程中,以强制对流 、自然对流或辐射的形式向室内供暖。

In the heating state, the compressor in the ground source heat pump unit works on the refrigerant and reversing the flow direction of the refrigerant through the four - way valve. By water absorption cycle of underground soil or groundwater in the heat by refrigerant / water heat exchanger in the evaporation of refrigerant, the heat absorption in the water circulation to the refrigerant, and then through the condensation of refrigerant / air heat exchanger refrigerant in the refrigerant circulation at the same time, the air circulation of the refrigerant the heat brought by absorption. In the course of the heat transfer to the interior, the heat is heated indoors in the form of forced convection, natural convection, or radiation.

夏季制冷

Summer cooling

在制冷状态下,地源热泵机组内的压缩机对冷媒做功,使其进行汽-液转化的循环。通过冷媒/空气热交换器内冷媒的蒸发将室内空气循环所携带的热量吸收至冷媒中,在冷媒循环的同时再通过冷媒/水热交换器内冷媒的冷凝,由水路循环将冷媒所携带的热量吸收,最终由水路循环转移至地下水或土壤里。在室内热量不断转移至地下的过程中,通过冷媒-空气热交换器,以13℃以下的冷风的形式为房供冷。

In the cooling state, the compressor in the ground source heat pump unit works on the refrigerant to make the steam - liquid conversion cycle. The refrigerant / air heat exchanger in the evaporation of refrigerant to air circulation carried by the heat absorption to the refrigerant, and then through the condensation of refrigerant / water heat exchanger refrigerant in the refrigerant circulation at the same time, by water circulating the refrigerant carries the heat absorbed by water circulation transfer finally to groundwater or soil. In the process of indoor heat transfer to underground, the cold medium air heat exchanger is used as cold air in the form of cold air below 13 centigrade.

简单的来说就是:

In a simple way, it is:

在冬季,把土壤中的热量“取”出来,提高温度后供给室内用于采暖;

In winter, the heat in the soil is "taken" out, and the temperature is raised to the room for heating.

在夏季,把室内的热量“取”出来释放到土壤中去,并且常年能保证地下温度的均衡。

In summer, the heat of the room is "taken" out and released into the soil, and the equilibrium of the underground temperature can be guaranteed for the year.
