Abstract

Предложена двухконтурная холодильная установка, содержащая контур холодильной камеры, работающий на хладоне, таком как R-134A, и контур морозильной камеры, работающий на углекислом газе (CO), в которой контур холодильной камеры содержит компрессор (1), работающий на хладоне, конденсатор (2) хладона и испаритель (3) холодильной камеры, и контур морозильной камеры содержит компрессор (4), работающий на углекислом газе, испаритель (5) морозильной камеры, электронный контроллер с датчиками и реле давления, при этом контур холодильной камеры дополнительно содержит дросселирующее устройство для хладона, а контур морозильной камеры дополнительно содержит дросселирующее устройство для углекислого газа, причем дросселирующее устройство для хладона и дросселирующее устройство для углекислого газа являются компонентами конденсатора-теплообменника (7) и расположены и выполнены таким образом, чтобы обеспечить теплообмен между дросселирующими устройствами.A double-circuit refrigeration unit is proposed, comprising a refrigerating chamber circuit operating on freon, such as R-134A, and a freezer circuit operating on carbon dioxide (CO), in which the refrigerating chamber circuit contains a compressor (1) operating on freon, a condenser ( 2) freon and the evaporator (3) of the refrigerating chamber, and the circuit of the freezer contains a compressor (4) operating on carbon dioxide, an evaporator (5) of the freezer, an electronic controller with sensors and a pressure switch, while the circuit of the refrigerating chamber additionally contains a throttling device for freon, and the freezing chamber circuit additionally contains a throttling device for carbon dioxide, and the throttling device for freon and a throttling device for carbon dioxide are components of the condenser-heat exchanger (7) and are located and made in such a way as to ensure heat exchange between the throttling devices.
