This thesis analyzes the types and art trait of solar-assisted heat pump water heater, the development trend of direct expansion solar-assisted heat pump water heater, makes a summary of these research results from six aspects. On the basis of these works and from the point of view of receiving optimum solar radiation , the thesis develops a novel design model of direct expansion solar-assisted heat pump water heater with a truncated cone collector/evaporator, theoretically analyzes the heat that the system can absorb, compares its ability with other two types of cylinder and flat plate ones, and calculates COP and EER with computer aids. The results show that a truncated cone direct expansion solar-assisted heat pump water heater can absorb not only more solar energy but heat energy in air. It takes on favorable thermal performance. Under the average day in February which is of the worst weather throughout the year in Kunming, the COP is about 4. 2, EER is about 2.9 . The heat absorbed by the system are more than those of the other systems. The system is very great in terms of saving

Studied the solid particles cyclone separation under structural parameters and operating parameters of different hydrocyclone, the results showed that major factor influence split ratio is in the ratio of entrance to exit pressure of hydrocyclone. Exit pressure has a certain influence on the split ratio, the various of the diameter and cone angle of hydrocyclone (in the ratio of entrance to exit pressure is constant) have no influence on split ratio; With diameter and cone angle increase, the separation granularity gradually increasing and recovery ratio decreasing; With entrance pressure increase, the separation granularity of hydrocyclone decrease, the split ratio of underset will increase slowly; With the diameter of overflow pipe increase, the separation granularity of hydrocyclone increasing and recovery ratio decreasing; With the diameter of underset pipe increasing, the separation granularity of hydrocyclone decreasing and recovery ratio increasing.
