The Design and Experimental Researches of Medium-Sized Ground Source Heat Pump Incubator

Article Preview

Abstract:

A kind of ground source heat pump incubator which absorbs the heat of soil as heat source of incubator was designed in this paper. The heating condenser was improved and optimized by adopting the three-level distributed heating way, and avioded the high temperature radiation influence on hatching egg in traditional electric incubator. In addition, the temperature field of incubator had good uniformity and the power consumption of temperature equilibrium was effectively reduced. It was better to stimulate the embryonic development by utilizing continuous variable temperature bionic hatching mode, and the growth adaptability of poults was improved as well. Hatching experiments showed, the main performance indexes of ground-source heat pump incubator meet the relevant national standards, the hatchability of fertilized eggs is above 91.4% and the rate of healthy poults is above 97.9%;The whole energy-saving rate of incubator is about 60% to 65%, reducing CO2, SO2 and dust emissions, thus the effect of energy saving and emission reduction is remarkable, and achieved good social and economic benefits.
