建立了一台先进的家用吸收式热泵（AHP）试验台，并进行了稳态运行试验。AHP旨在取代热水供暖系统中使用的传统锅炉，这在欧洲非常常见，在美国也越来越受到关注。为了与传统锅炉竞争，AHP必须适用于不同的热源和供暖系统。一个有吸引力的热源是环境空气，它很容易以相对较低的成本获得。环境空气的主要缺点是每日和季节温度变化较大，与其他热源（如地热）相比，温度较低。为了适应这些挑战性条件，提出了一种具有可调成分的功率控制层次分析法。选择单级吸收式热泵作为开发的基础。 为了实现单价系统（即AHP是唯一提供热量的设备），并允许在热源温度低于0°C（32°F）的情况下运行，选择氨水作为工作对。吸收式热泵由一台发电机、一台溶液热交换器和一台溶液冷却部分冷凝器、一台冷凝器、一台预冷器、一台蒸发器、一台吸收器、一台溶液泵和一台制冷剂存储器组成，该发生器具有一个浓溶液的存储空间。AHP在-15°C（5°F）温度下的最大加热能力为20千瓦（68000 Btu/h）。最高热水温度为55摄氏度（131华氏度）。燃烧器、溶液阀和膨胀阀可连续调节。贮存允许将浓溶液的质量分数从17%转移到50%。组合式部分冷凝器/溶液热交换器在质量分数为25%至50%时工作良好。 这相当于热源温度从-10°C（14°F）到10°C（50°F），因此最高热水温度可能达到55°C（13°F）。在此范围内，工艺加热性能系数（COPH）的变化范围为1.4至1.7。低于-10°C（14°F）时，COPH急剧降低。然而，在低至-20°C（-4°F）的温度下，可以在热泵模式下运行AHP。单元:双引文:研讨会，ASHRAE交易，第105卷，第。1.

A test rig of an advanced absorption heat pump (AHP) for domestic heating has been built and tested in steady-state operation. The AHP is intended to replace conventional boilers used in hot water heating systems, which are very common in Europe and gaining more interest in the United States. To be competitive against conventional boilers, the AHP must be adaptable to different heat sources and heating systems. An attractive heat source is ambient air, which is easily accessible at relatively low cost.The main disadvantage of ambient air is the greater variation in daily and seasonal temperature and the lower temperature compared to other heat sources such as ground heat. A power controlled AHP with adjustable composition is proposed to match these challenging conditions. A single-stage absorption heat pump was chosen as the base for the development. To enable a monovalent system (i.e., the AHP is the only device to provide heat) and to permit operation at heat source temperatures below 0°C (32°F), ammonia-water has been chosen as the working pair. The absorption heat pump consists of a generator, which possesses a storage volume for strong solution, a solution heat exchanger combined with a solution-cooled partial condenser, a condenser, a precooler, an evaporator, an absorber, a solution pump, and refrigerant storage.The AHP is designed for a maximum heating capacity of 20 kW (68000 Btu/h) at -15°C (5°F). The maximum hot water temperature is 55°C (131°F). The burner, the solution valve, and the expansion valve are continuously adjustable. The stor-age allows shifting the mass fraction of the strong solution from 17 mass% to 50 mass%.The combined partial-condenser/solution heat exchanger works well at mass fractions from 25 mass% to 50 mass%. This corresponds to heat source temperatures from -10°C (14°F) to 10°C (50°F), whereby a maximum hot water temperature of 55°C (13°F) is possible. Within this range, the process heating coefficient of performance (COPH) varies from 1.4 to 1.7. Below -10°C (14°F), the COPHdecreases drastically. It is possible, however, to operate the AHP in heat pump mode at temperatures as low as -20°C (-4°F).Units: Dual
