2、到了50%,其超高的經(jīng)濟(jì)性,遠(yuǎn)超傳統(tǒng)空調(diào)。并且,地源熱泵的冷熱源全年溫度比較穩(wěn)定,一般維持在9—16℃,因此,地源熱泵空調(diào)系統(tǒng)的制冷制熱性能也是不錯(cuò)的。本課題主要研究的是上海市某別墅采用地源熱泵空調(diào)系統(tǒng)實(shí)現(xiàn)夏季制冷,冬季供熱工況的設(shè)計(jì)方案。本設(shè)計(jì)地源熱泵系統(tǒng)的地下?lián)Q熱器埋管方式采用了垂直U型埋管,解決了傳統(tǒng)空調(diào)運(yùn)行費(fèi)用高、運(yùn)行效率低、噪音大、維護(hù)費(fèi)用高、使用壽命短等缺點(diǎn),真正做到了高效、節(jié)能、環(huán)保、舒適的要求。在本次畢業(yè)設(shè)計(jì)中,我先通過計(jì)算各個(gè)房間的負(fù)荷,確定各個(gè)房間的風(fēng)機(jī)盤管型號(hào),再布置新風(fēng)系統(tǒng),然后進(jìn)行水力計(jì)算,確定個(gè)管
