摘　　要：本文设计了一个由太阳能冷管和跨临界CO2热泵组成的联合供能系统,可以实现制冷+供热水、制热+供热水、单独制冷、单独制热、单独供热水的功能。夏天用太阳能冷管制冷并提供生活热水,当太阳能不足或阴雨天气时,由跨临界CO2系统替代;冬天用跨临界CO2热泵制热并提供热水;过渡季节晴天时由太阳能冷管提供热水,阴雨天气时由跨临界CO2系统替代。这是一种将太阳能冷管吸附式制冷技术和跨临界CO2热泵技术联合的可实现制冷、制热和供热水功能的联合系统,集空调热泵和热水器于一体,是一个利用新能源、环保节能的紧凑型系统。A combined system of solar cooling tube and Vans-critical CO2 heat-pump is designed in this paper. The system could provide five operation modes such as refrigeration ＋ hot water, heating ＋ hot water, refrigeration, heating and hot water. In the summer, solar cooling tubes supply refrigeration and hot water, and can be replaced by trans-critical CO2 heat-pump system when cloudy or rainy. In the winter, trans-critical CO2 heat-pump system supplies heating and hot water. During the transitional season, hot water supplied by solar refrigeration tubes when sunny days, otherwise by the trans-critical CO2 heat-pump system. Combining solar adsorption refrigeration technology with trans-critical CO2 heat-pump technology, the system can carry out the function of air-conditioner, heat-pump and water heater. It is a compact system with energy-saving and environment protection.
