Nowadays precision dew point hygrometers are mostly the type of light-electricity detection,thermoelectric refrigeration and specula-surface condensation dew point instrument internationally.
Using the method of optimal efficiency and maximal quantity of refrigerating output, a thermoelectricity refrigeration system commix with compress refrigeration is designed.
The application advantages and the possible problems of developing nonmechanical refrigerated container using dry ice are discussed deeply,and the respond solutions are put forward.
Operating costs of using the steam jet refrigeration system to cool the temperature of water in air conditioning system are lower than the refrigerative compressor.
According to the ZBO storage methods of other cyogenic liquids, an idea of centralized recondensation of liquid hydrogen in large containers by using cryocoolers was suggested.
By 52%-54% denisty indicator of lithium bromide, it is used to be absorptive refrigerant, hypnagogue and mitigative of medicine, and also to be electrolyte in ion-battery.
Passive and Hybrid Downdraught Cooling, which rely on natural cooling processes based on water evaporation and solar power, are now technically viable in many parts of the world.
This paper researches into enhanced heat transfer of condensation of splitting gas of waste plastics and R113 on the general smooth tubes,the screw tubes and the aculei finned tubes.
The calculations agree well with experimental results, which indicates that the model is instructive on the optimization of the dimension of inertance tube in Stirling type pulse tube cooler. 3.
Through the research on petroleum and nature gas, design a multi-source heatpump of single and double effect lithium bromide, the two stage heatpump unit, process of nature gas liquefaction etc.
