新型带热回收装置的热泵空调系统的应用研究

Study on the heat pump air conditioning system with a new heat recovery device

传统的风冷式热回收热泵系统只有在制取生活热水这段时间内是高效运行的,而传统的水冷式热泵系统难以实现冬季的热泵循环,设计一种新型的风水冷热水空调系统,在热回收器上连接冷却塔,在夏季制冷运行中,将不需要热回收的那部分热量完全通过冷却水带走,保证系统都能在较高性能系数的状态下运行。经过实际工程运行验证,系统的最高制冷性能系数可以达到3.5,最高综合性能系数可以达到6.5,达到了节能的目的。

The traditional air - cooled heat - recovery heat pump system only runs effectively in the process of producing domestic hot water, and it is difficult to use traditional water- cooled heat pump system to achieve heat pump circulation in winter. The paper designed a new wind - water cooling and heating water conditioner system, connected cooling tower with heat recovery device, which used cooling water to completely remove the heat that did not need heat recollection, in order to ensure that the system could work efficiently with higher performance coefficient. Through the verification of practical engineering operation, the system＇s highest cooling performance coefficient could reach 3.5, the maximum comprehensive performance coefficient can reach 6.5, and could save energy.
