Embodiment Construction

[0033] figure 1 A compressor system 1 according to the invention is shown. The compressor system 1 here comprises three different circuits. The first circuit, the main refrigerant circuit 2 , comprises a compressor 3 , a condenser 4 , a dry filter 5 , an expansion device 6 and an evaporator 7 . These elements are connected to each other through a pipeline system, and the entire circuit 2 is hermetically sealed, and contains and utilizes a refrigerant (such as CO 2 ) operate under pressure.

[0034] The expansion device 6 employs an adjustable expansion valve or a fixed constriction. In a compressor system using an expansion valve, it is important that the expansion valve is constantly supplied with fluid. Thus, the dry filter 5 is located upstream of the expansion valve 6 and has an outlet at the bottom of its container (not shown). This ensures that the expansion valve 6 is always supplied with fluid and thus operates correctly.

[0035] The second circuit 8 , the cooling...

Abstract

The invention relates to a system and a device for cooling and / or warming which comprises at least a refrigerant circuit (2) with at least a compressor (3), a condenser (4), an evaporator (7) and an expansion means (6). The invention is effected by the evaporator and the condenser being combined / integrated in a single common unit (16) which comprises an internal heat exchanger (19).

Description

technical field [0001] The present invention generally relates to a compressor system having a closed refrigerant circuit for cooling and / or heating purposes, the refrigerant circuit comprising at least a condenser and an evaporator. In particular the invention relates to a system and arrangement for cooling and / or heating the interior of a vehicle, in particular the cab / driving space of a commercial / heavy-duty vehicle with a tiltable cabin. More specifically, the invention relates to a compressor system comprising at least one additional auxiliary low pressure circuit for transferring heat and cold using water and / or glycol or other medium suitable for transferring heat and cold. Background technique [0002] As is known, air conditioning systems in motor vehicles generally include an air-cooled condenser located at or near the front of the vehicle, an evaporative condenser located at a location in the vehicle cabin, such as in or under the dashboard. devices, and the line...
