无散热损失的热泵型供热系统研究
Study on a heat-loss free heat pump heating system
摘要：
提出了一种可在环境温度下实现能量输运的供热系统。该系统利用吸收式热泵原理，以氨水为工作流体，发生器和冷凝器布置在热源端，而吸收器和蒸发器布置在热用户端，利用吸收器中溶液吸收蒸气所放出的吸收热来提供热能。由于采用质量分数不同的氨水作为能量载体，因此，可以在环境温度下实现能量输运，没有散热损失；同时，由于该系统利用潜热供热，大大减少了泵功耗。分析结果表明，当供热距离较远时，该系统具有明显优势。
Abstract：
Presents a heating system based on absorption heat pumps, in which energy can be transferred by ammonia-water solutions at an ambient temperature. The absorber and evaporator are located at the heat demand side while the generator and condenser at the heat supply side, and the absorption heat in the absorber is supplied to heat consumers. The energy is transferred by the latent heat of absorption solutions with different concentrations, so to avoid the heat loss during the transferring process, the pump-consumed power is much lowered due to the latent heat between the ammonia solutions with different concentration is very large. This system has more remarkable advantage for longer transportation distance.
Keywords:absorption type heat pump, heating system, ammonia-water solution
