采用轻质板翅式换热器的喷射热泵机组
摘要：
一种采用轻质板翅式换热器的喷射热泵机组，属于新能源及节能技术领域。这种喷射式热泵机组采用双喷射泵并联方案，用新型轻质板翅式换热器代替了管壳式换热器，使得机组的负荷可控范围宽，整体重量降低了30％左右，系统占地面积减小40％以上，系统性能指标上升10％-20％。不仅直接降低了系统成本，还大幅度减少了系统制冷剂的用量，降低了用户的运行成本。同时冷凝器采用的高效板式换热器，是一种应用广泛的高效节能设备，而且降低了换热器的投资和维护费用，增加了整套设备的可应用推广性。该喷射式热泵机组结构简单、使用维护方便、系统正压运转的高效喷射式热泵机组，其应用推广性得到了很大的提高。
摘要（英）：

The invention relates to a jet heat pump unit using a light plate-fin heat exchanger, belonging to the technical fields of new energy and energy conservation. The jet heat pump unit adopts a dual jet pump parallel connection scheme. The shell-and-tube heat exchanger is replaced by the novel light plate-fin heat exchanger so that the load controllable range of the unit is wide, the weight of the whole body is reduced by about 30%, the system occupy area is reduced by more than 40 % and the system property indexes are increased by 10-20%. The system cost is directly reduced, and the use amount of the system refrigerant is greatly decreased, thereby reducing the operation cost of a user. Meanwhile, an efficient plate heat exchanger used by a condenser is efficient energy-saving equipment with a wide application range; and furthermore, the investment and maintenance cost of the heat exchanger is reduced so as to improve application and popularization properties of the whole set of the equipment. The jet heat pump unit is an efficient jet heat pump unit with a simple structure, convenience for use and maintenance and positive-pressure operation in the system. The application and popularization properties are greatly improved.
