FIELD: physics.
SUBSTANCE: combined device for cooling and creating vacuum has a cooling circuit, which contains a compressor for compressing the coolant, a condenser for condensing coolant coming from the compressor, expanding apparatus for reducing pressure in the coolant and at least one evaporator for evaporating the coolant. The cooling circuit is divided into a high-pressure branch and a low-pressure branch for apparatus for creating vacuum inside a container. The apparatus for creating vacuum is connected to the low-pressure branch of the cooling circuit so as to use the pressure difference created in the cooling circuit to create vacuum in the container. The proposed device is realised using a method of composite cooling and creating vacuum.
EFFECT: use of the present group of inventions provides for good operational characteristics while saving energy.
