在夏季,當室外溫度達到40℃時,由于換熱效率降低,冷量將下降20%～40%;在冬季,當室溫下降到-10℃時,供熱量將下降到15%～30%,而且要反復地沖霜來保證機組的正常運行。地源熱泵 www.zhongrui.cc
In the summer, when the outdoor temperature reaches 40 DEG C, because of low heat exchange efficiency, cooling capacity will be decreased by 20% ~ 40%; in the winter, when the temperature dropped to -10 DEG C, heating capacity will decrease to 15% ~ 30%, but also to repeatedly washed cream to ensure the normal operation of the unit.
對于地源熱泵,換熱器是介質(zhì)和大地地表淺層換熱,地表淺層是一個巨大的太陽能集熱器,收集了47%的太陽能,相當于人類每年利用能量的500多倍。地能不受氣候、資源、地域、地質(zhì)結構限制。這種低溫位熱能是人類可以利用的清潔的可再生能源。冬季通過地源熱泵將大地中的低溫位熱能提高品位對建筑供熱,同時蓄存冷量以備夏季使用;夏季通過地源熱泵將建筑物內(nèi)的熱量轉移到地下,對建筑物進行供冷,同時對地能蓄存熱量以備冬季使用。其溫度大約為年平均氣溫,基本不受外界環(huán)境影響。
For ground source heat pump, heat exchanger is medium and the earth surface layer heat, shallow ground is a huge solar collector, collected 47% of the solar energy, the human equivalent of energy each year more than 500 times. Can not affected by climate, resources, geographical, geological structure limits.
由于地源溫度一年四季相對穩(wěn)定,使得地源熱泵機組運行更可靠、穩(wěn)定,也保證了 系統(tǒng)的高效性和經(jīng)濟性。www.wanzhi100.com濟南春季高考
Due to the source temperature is relatively stable throughout the year, the operation of ground source heat pump unit is more reliable, stable, also to ensure the efficiency and economy system.
夏季,風冷機組將廢熱排入大氣,使室外溫度升高;水冷機組不僅將廢熱排入大氣,使室外溫度升高,還將水蒸氣帶入大氣中,冷卻塔的噪音及霉菌污染使周圍環(huán)境品質(zhì)變差;冬季,風冷、水冷機組吸收大氣環(huán)境中的熱量,導致惡劣大氣環(huán)境更加惡劣。
