In the data center, air conditioning has been carried out throughout the year to remove waste heat of servers. In order to realize efficient cooling, it is important to use cold outdoor air in winter. Therefore we study the performance of the air conditioning system that uses outside air in winter. In the proposed system, it is possible to switch compression cycle and free cooling cycle. In this report, we construct the static mathematical models of this system and verify the validity of this mathematical model by experiment. Validity of the mathematical model has been confirmed as a result. And we elucidated the static characteristics of this system in regard to outdoor temperatures and Indoor temperatures.
