【摘要】：如何選擇制冷方式和選擇哪種制冷方式最優(yōu)是目前區(qū)域供冷系統(tǒng)(DCS)規(guī)劃建設(shè)時(shí)討論的熱點(diǎn).文中以所建立的電壓縮式和蒸汽吸收式制冷系統(tǒng)的分析模型為基礎(chǔ),進(jìn)行了以制冷系統(tǒng)單位冷量的經(jīng)濟(jì)成本最低為目標(biāo)的對(duì)比研究.結(jié)果表明:蒸汽熱價(jià)/電價(jià)比越大,兩種制冷方式經(jīng)濟(jì)成本相等時(shí)的蒸汽輸送距離越短;當(dāng)蒸汽熱價(jià)/電價(jià)比大于1.13時(shí),蒸汽吸收式制冷系統(tǒng)的經(jīng)濟(jì)成本恒高于電壓縮式系統(tǒng).由此得到結(jié)論:不同的制冷站應(yīng)當(dāng)結(jié)合蒸汽輸送距離、電價(jià)和蒸汽熱價(jià)選擇適宜的制冷方式.
[Abstract]:How to choose the refrigeration mode and which one is the best is a hot topic in the planning and construction of regional cooling system (DCS). Based on the analytical models of electric compression refrigeration system and steam absorption refrigeration system, a comparative study has been carried out with the objective of the lowest economic cost per unit cooling rate of the refrigeration system. The results show that the shorter the steam transport distance is when the cost of the two refrigeration modes is equal with the increase of the ratio of steam heat price to electricity price. When the ratio of steam heating price to electricity price is greater than 1.13, the economic cost of steam absorption refrigeration system is always higher than that of electric compression system. It is concluded that different refrigeration stations should combine steam transport distance, electricity price and steam heat price to choose suitable refrigeration methods.
