The wintering honey bee chambers were constructed and inside environment factors were analyzed to provide high technology for efficient wintering of honeybee colonies. As a result of this study, inside air temperature of yongin chamber under the wide range of outside temperature condition was found to be appropriated for wintering of bee, and inside temperature of beehive was about 2℃ higher than the air temperature in the chamber. The fan operation schedule did not control the high temperature down properly in the chamber, It was necessary to find a new fan operation schedule to be able to provide the optimum temperature for wintering honey bee colonies. inside humidity variation of Yongin chamber was very much depended on outside humidity.
