| Abstract | 基于非对称空间传热理念,设计了一种新型双回路逆流干式蒸发器,并将其安装在空气源热泵机组上进行实验测试。理论计算和测试结果表明：制冷工况下,干式蒸发器总表面传热系数的理论计算值为1709.4w/(m^2·K),实测值为1938.1w/(m^2·K),后者比前者大11.8%；制热工况下,干式蒸发器总表面传热系数的理论计算值为1834.9w/(m^2·K),实测值为2226.4w/(m^2·K),后者比前者大17.5%。对误差原因进行了分析,结果显示：实际测试时壳程流速增大；蒸发器内换热管的污垢热阻很小。 |
| Other Abstract | Based on the asymmetric space heat transfer concept, designs a novel double-loop counter- currrent dry-expansion evaporator equipment, and installs it to an air-source heat pump unit and performs the experiment. Theoretical calculation and test results show that the calculated value of the overall surface coefficient of heat transfer is 1 709.4 W/(m^2· K), and the measured value is 1 938.1 W/(m^2 · K) for dry-expansion evaporator under cooling condition, the latter is 11.8% higher than the former; and that the corresponding values under heating condition are I 834.9 W/(m^2 ·K)and 2 226.4 W/(m^2 · K)respectively, the latter is 17.5 % higher than the former. Analyses the error cause and concludes that the flow velocity in shell-side of the measured evaporator is increased, and the fouling resistance of heat exchanger tube in the measured evaporator is nearly zero. |
