地源热泵的低温热源有多种，用得多的主要是地热利用的排水、浅层冷水和土壤。那么地源热泵对低温热源有什么样的要求呢？

Ground source heat pumps have many kinds of low temperature heat sources. The most widely used are geothermal 

drainage, shallow water and soil. Then, ground source heat pump for low-temperature heat source what kind of 

requirements?

一、低温热源的温度要尽量高，例如从10℃的冷水中取热送至60℃的高温环境，其提升的温差为50℃；若从35℃的地热排水中提取热量，同样送至60℃的高温环境，则其提升温差只有25℃。

A low temperature heat source temperature should be as high as possible, such as high temperature heat from the 

cold water of 10 DEG C to 60 C in the ascending temperature is 50 DEG C; if from 35 DEG C to extract heat high 

temperature geothermal water, the environment also sent to 60 DEG C, the temperature increase only 25 degrees C.

二、低温热源要有足够的热量可以被提取，而且提取热量的能耗要尽量小。从地热利用系统的排水取热是废物利用，额外增加的能耗很少。

Two, the low temperature heat source should have enough heat to be extracted, and the energy consumption of the 

extraction of heat should be as small as possible. Heat extraction from geothermal systems is a waste utilization, 

with little additional energy consumption.

三、低温热源对金属设备的腐蚀应尽量小，从这点看，地热系统排水作低温热源比浅井冷水差，因为一般地热水或多或少都对金属有腐蚀，而浅井冷水水质较好，一般很少腐蚀。

Three, low temperature heat source on the corrosion of metal equipment should be as small as possible, from this 

point of view, the geothermal system drainage as low temperature heat source than the shallow well water is poor, 

because generally more or less metal corrosion of hot water and cold water, shallow well water quality is better, 

in general little corrosion.

四、低温热源的温度波动要尽量小，这与热源是否有充足的热量可供提取有很大关系。一般来说，浅井冷水的温度比较恒定；土壤取热后温度是否会下降则与取热量和埋设的换热设备占地面积有一定关系；地热利用后的排水温度能否保持恒定，与系统设计时采用的控制设备和自控的质量有关。

Four, low temperature heat source temperature fluctuations should be as small as possible, and this heat source 

has sufficient heat for extraction has a lot to do with. In general, Asakai cold water temperature is relatively 

constant; soil heat temperature will decline, and taking the heat and buried heat exchanger in the area have a 

certain relationship; geothermal utilization after water temperature can be maintained constant, and relevant 

quality control equipment and automatic control system designed by the.
