The technology of air circulation dyhumidification in the dehydration system of fruits and vegetables and basical structure features of the new type dehydration equipment designed according to this technology was prssented.
fter briefly discussing and analysing how to raise electricity-generating thermal circulation efficiency, this paper works out two new kinds of plans for circulating electric power generation technology, namely high pressure air circulation and oxygen-enriched air circulation respectively.
And it was suggested that the air circulation should be strengthened so as to narrow the differences of temperature and humidity of upper and lower spaces inside the growing room to improve the yield and quality of V. volvacea.
The systematic analysis and optimization calculation of a humid air cycle have shown that reheating has a marked effect on enhancing the humid air cycle performance. Under the existing technical conditions(turbine inlet temperature 1300℃,pressure ratio 10～30)the cycle thermal efficiency can be as high as 59.2-60.2% with a specific power of 620～980 kJ/kg air.
In this paper, the feasibility of the application of the air- cycle refrigeration on air conditioner of the railway passenger car is analyzed. We think that this scheme is feasible in theory and experiments should be made to put it into practice.
The structure of electricity heating-tube and the reason of accident are discussed based on some problems raised in the air-cycle resistance furnace,and the effective measure and several aspects should be taking into account in designing are put fornard.
Combining with the vapour-cycling cooling system and the air-cycling cooling system,the paper puts forward an engineering plan for pod thermal design. The analysis of heat-load and the solving method of environmental control system in complicated environment is presented.
