5 years ago, ground temperature air conditioning regards forward position as science and technology, our newspaper ever had made large space report. Be in 5 years this are next medium, whole society is right but the attention of second birth the sources of energy is spent warm up ceaselessly, for a short while solar energy generates electricity, wind energy generates electricity make van of vogue of science and technology, ground temperature air conditioning does not grab what limelight it seems that. And pay close attention to one go to the fields afresh when reporter plan when heat energy is used, just know to be in Beijing, air conditioning of land source hot pump is casual an extensive already promotion use. String 1
String of the most effective air conditioning technology 7
The history that land source hot pump uses is OK restrospect to 1912 a patent of Switzerland, and its business application has 20 old histories only however. Although the history is not long, but promotion is very fast, current, a lot of developed countries such as the United States, Japan, Germany, France, Sweden are using land source extensively to heat up pump technology. This technology is maintained to be one of air conditioning technologies with the most effective this century by a lot of air conditioning experts. String 2
Say simply, go up under the ground because of summertime underground temperature temperature, the terrestrial heat that so source hot pump uses passes groundwater namely (or the ground buries a canal) this agency will take away indoor quantity of heat, winter is contrary, achieve the result of refrigeration heating thereby. System of land source hot pump is to pass a few electric energy input will finish these jobs. String 1
For instance, get authentic a pair deep well of 2500 meters the heat of the earth's interior, take water, answer fill, temperature giving water 65 Celsius, give water to measure 50 stere / hour. Be like direct heating, the temperature of water of the heat of the earth's interior can reduce 45 Celsius only, use difference in temperature 20 Celsius, but heating area 23 thousand square metre. Use hot pump to reclaim heat energy of tail water of the heat of the earth's interior, temperature can reduce 20 Celsius, expand again use difference in temperature 25 Celsius, raise heating area 29 thousand square metre. Enlarged 1.24 times to the efficiency of well of the heat of the earth's interior likewise, heat source builds cost by 300 multivariate / building square metre reduces 200 yuan / building square metre, managing investment 40% .
