    • Heat pumps consume power in order to transfer heat from a source to a higher-temperature sink. This invention enables spontaneous heat transfer from a heat source to a small portion of the generally warmer working fluid that is locally cooled by the Bernoulli effect to a temperature below that of the heat source. The Bernoulli effect occurs in a Venturi shaped duct shaped to maintain laminar flow. Heat-transfer efficiency is improved by restriction of the heat transfer to a small portion of the Venturi in which the flow temperature, velocity, pressure gradient and the Nusselt effect all enhance heat transfer. Within this region, heat transfer is maximized by a thermally conducting grid extending across the Venturi neck. ® KIPO & WIPO 2008
    • 热泵消耗功率,以将热量从源传输到更高温度的水槽。 本发明使得能够从热源到由伯努利效应局部冷却到低于热源温度的通常较暖的工作流体的一小部分的自发热传递。 伯努利效应发生在文丘里形管状,以保持层流。 通过限制传递到文丘里的一小部分的流量温度,速度,压力梯度和努塞尔效应都能增强热传递,从而提高了传热效率。 在该区域内,通过延伸穿过文丘里颈部的导热网格使热传递最大化。 ®KIPO&WIPO 2008

    • The present invention concerns a cooling or heating apparatus including at least a 5 compressor (1), a condenser (2), an expansion apparatus (7), a vaporizer (9) and a space for liquid accumulation (10). The invention is characterized essentially by a control system consisting of an electronic bubble detecting device (4) for detecting the occurrence of bubbles in the refrigerant condensate. The bubble detecting device (4) is attached in proximity to the condenser's (2) outlet or to its exit line, the bubble detecting device (4) is in electrical connection with an expansion apparatus (7) that is controlled electrically. The bubble detecting device (4) gives signals to the expansion apparatus (7). Gas bubbles in the condenser liquid affect the control system so that when the amount of gas bubbles registered/signal analyzed by the bubble detecting device (4) exceeds the set signal value for the presence of bubbles in the condensate there is a signal to the expansion apparatus' electric control unit (7) to shut off or alternatively to decrease the refrigerant flowthrough. W hen the gas bubble amount is absent or alternatively is less than the predetermined set signal value the expansion apparatus (7) is given a signal from the bubble detecting device (4) to the expansion apparatus' electric control unit (7) to increase the refrigerant flowthrough.

    • A falling film evaporator is provided for use in a two-phase refrigeration system or process system. The evaporator (80, 280) includes a shell (100) having an upper portion (102), a lower portion (104), and a tube bundle (106) having tubes extending substantially horizontally in the shell (100). A hood (112) is disposed over the tube bundle (106), the hood (112) having an upper end (114) adjacent the upper portion (102) above the tube bundle (106), the upper end (114) having opposed substantially parallel walls (116) extending toward the lower portion (104), the walls terminating at an open end (118) opposite the upper end (114).
