Résumé

Recently, the cooling load in winter has increased a great deal in a lot of office buildings, because the number of persons using computers at the office has rapidly increased. In order to address this situation, the author developed a multi-system that is able to operate cooling and heating for each indoor unit at the same time. Where R410A is usually used, an outdoor unit withstanding higher raised pressures has been designed. However, this system has some control functions to withstand maximum operating pressures 3.3 MPa. Therefore, you can use the current pipes for R410A, and do not have to replace the pipes. Moreover, the stability of the operating pressure has been improved, so that customers can feel more comfortable thanks to this system.
