【摘要】：傳統(tǒng)熱泵采用單一熱源(空氣源或水源),雖然也有利用多熱源(蒸發(fā)器)的復(fù)合熱泵,但往往采取蒸發(fā)器切換的工作模式,這種工作模式難以同時利用多熱源能量來達到制熱目的。雙蒸發(fā)器耦合的復(fù)合熱泵系統(tǒng)通過太陽能水源蒸發(fā)器與空氣源蒸發(fā)器協(xié)同工作來提高其制熱性能,但不同的蒸發(fā)器連接形式(串聯(lián)與并聯(lián))必然導(dǎo)致復(fù)合熱泵系統(tǒng)的制熱性能發(fā)生變化。本文利用熱力學(xué)方法對雙蒸發(fā)器采用不同連接形式的復(fù)合熱泵系統(tǒng)的熱力學(xué)性能進行了比較分析。研究結(jié)果表明:無論雙蒸發(fā)器并聯(lián)還是串聯(lián)連接的復(fù)合熱泵系統(tǒng)均較單一熱源(空氣源)的熱泵的制熱性能均顯著提高;雙蒸發(fā)器并聯(lián)連接的復(fù)合熱泵系統(tǒng)的能耗較雙蒸發(fā)器串聯(lián)連接的復(fù)合熱泵系統(tǒng)的能耗明顯下降,雙蒸發(fā)器并聯(lián)連接的復(fù)合熱泵系統(tǒng)需要增加一臺壓縮機,但其節(jié)能性顯著,也更具經(jīng)濟性優(yōu)勢。
[Abstract]:The traditional heat pump uses a single heat source (air source or water source), although there are also multiple heat sources (evaporator) of the composite heat pump, but often take the evaporator switching mode, It is difficult to achieve the purpose of heating by using multiple heat sources simultaneously. A hybrid heat pump system coupled with two evaporators is designed to improve the heating performance of solar water source evaporator and air source evaporator. However, different evaporator connections (series and parallel) will inevitably lead to changes in the heating performance of the composite heat pump system. In this paper, the thermodynamic performance of a composite heat pump system with two evaporators with different connection forms is compared and analyzed by thermodynamics method. The results show that the heating performance of the heat pump with double evaporators in parallel or series connection is significantly higher than that of the heat pump with a single heat source (air source). The energy consumption of the combined heat pump system connected in parallel with the double evaporator is obviously lower than that of the composite heat pump system connected in series with the double evaporator, and the energy consumption of the composite heat pump system connected in parallel with the double evaporator needs to be increased by one compressor, but its energy saving property is remarkable. Also more economical advantage.
