Research And Exploitation Of Solar Energy Preservation Pigpen In Frigid Zone

Aiming at characteristics of frigid zone in this paper, we developed and exploited three kinds of solar-energy preservation pigpens available for frigid zone. We calculate and analyze quantitatively heat preservation characteristics and solar energy-absorbing capacity of solar energy preservation pigpen. According to heat balance theory, we calculate three kinds of average temperature of solar energy preservation pigpen in the coldest month. We analyze economic, social and zoology benefit of pigpen by dynamic cash analytic method and draw conclusion that we can increase pig's growth, diminish consuming of feedstuff, decrease raising cost, increase farmers' income. Improve agricultural zoology environment by adopting solar energy preservation pigpen which is an item with economic, social and zoology benefit. We spread three kinds of solar energy preservation pigpen developed and exploited and do the experiment and check. In the end, we know that temperature of pigpen meet the design demand with excellent heat preservation capability and novel structure and fine solar energy collection windows which is original in Heilongjiang province. We establish building technique criterion establishment of heat preservation pigpen available for farmers (DB23/T186-2002). which provide foundation for standardizing reasonably the building of solar energy preservation pigpen.
