Modernized refrigeration cycle includes two consecutive expansions with two expansion devices and two condensers, wherein the first condenser liquefies refrigerant after compressor and the second condenser liquefies refrigerant after the first expansion device. The cooling medium for the second condenser is either air to be conditioned in the refrigeration system or another available medium. Invention presents sealed systems of air conditioners, dehumidif?ers and heat pumps operating per aforementioned refrigeration cycle that allows enhanced dehumidif?cation with efficiency improvement in cooling mode and heating capacity and efficiency increase in heating mode. |
