地源热泵针对低温热源的要求

发布日期:2018-04-09 作者:地源热泵 点击:

地源热泵的低温热源有多种,实际上用得最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 pump has many kinds of low temperature heat source, in fact, the most widely used are geothermal drainage, shallow cold water and soil. So ground source heat pump for low temperature heat source what kind of requirements?

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℃。温差愈大,热泵的供热系数愈小,热泵的节能效果就愈差。

The 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. The greater the temperature difference is, the smaller the heating coefficient of the heat pump is, the worse the energy saving effect of the heat pump is.

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。从这一角度看,它比从浅井冷水取热好。但是如果该地区不存在地热井,那么从浅井冷水取热或从土壤取热是地热热泵的可选低温热源。

Low temperature heat source has enough heat to be extracted, and the energy consumption of extracting heat should be as small as possible. Drainage from geothermal systems is a "waste" utilization, with little additional energy consumption. From this point of view, it is better than getting cold water from shallow wells. However, if there is no geothermal well in this area, heat extraction from shallow well water or heat from soil is an optional low temperature heat source for geothermal heat pump.

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。

Low temperature heat source on the metal corrosion of 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.
