Data on industrial heat pump installations in some countries and distribution of these according to heat pump type and industry sector as well as heat source temperatures are reported 本文也給出了,在一些地區(qū),根據(jù)熱源溫度、熱泵形式和工業(yè)區(qū)的特點(diǎn)來(lái)設(shè)計(jì)的熱泵的安裝與分布情況的數(shù)據(jù)。
The mathematic models of them are founded and computed with the new working pairs tfe / tegdme . the effects of heat source temperature , temperature drop of heat source in systems , output temperature , temperature of cooling water , concentration range of cycle on the quantity and quality of recovered heat are analyzed in the paper . the results show that in the three cycles , in the concerned range of parameters , cop of the high - low cycle ranges between 0 . 32 and 0 . 34 , coe ranges between 0 計(jì)算結(jié)果顯示,在所計(jì)算的三種方式的循環(huán)中、在所研究的參數(shù)變化范圍內(nèi),高低型循環(huán)的cop大體維持在0 . 32 0 . 34的范圍內(nèi)、 coe大體維持在0 . 53 0 . 6的范圍內(nèi),并聯(lián)型循環(huán)的cop大體維持在0 . 29 0 . 32的范圍內(nèi)、 coe大體維持在0 . 48 0 . 53的范圍內(nèi),而低高型循環(huán)的cop與溫升是一對(duì)很尖銳的矛盾:溫升在60左右時(shí), cop只有0 . 1左右,而要達(dá)到較高的cop時(shí),溫升只能達(dá)到很低的30 40 。
