Embodiment Construction

[0044] figure 2 A circulation system 100 for a commercial vehicle according to an embodiment of the invention is shown. The circulation system 100 comprises: a first circuit 10 which conducts a first fluid F1 and which is implemented as a refrigeration cycle; and a second circuit 20 which conducts a second fluid F2 and which is implemented as a heating cycle.

[0045] The second circuit 20 comprises, for example, a radiator, a pump, a heater, a heating-heat exchanger (heating-WT), which is preferably arranged in the roof system of the commercial vehicle, preferably a plurality of convectors and / or a heating device And a further heating-heat exchanger (heating-WT) which is preferably arranged in the front box of the commercial vehicle. The second circuit 20 is operatively connected to an engine of the commercial vehicle, for example a hybrid engine and / or an electric motor. The second circuit 20 also includes a plurality of valves, for example regulating valves, 2 / 3-way valv...

Abstract

The invention relates to a circulation system for a commercial vehicle. The circulation system has a first circuit (10) which guides a first fluid (F1) and is preferably a cooling circuit, and a second circuit which guides a second fluid (2) and is preferably a heating circuit. The circulation system comprises a heat exchanger (WT1). According to a circulation system-mode, the first fluid (F1) can be fed to the heat exchanger (WT1) for achieving the heat exchange communication with the second circuit (20), and preferably, the first fluid (F1) is not fed to the heat exchanger (WT1) for preventing the heat exchange communication with the second circuit (20). Alternatively or complementally, the first circuit (10) comprises an expansion mechanism (EO). According to a circulation system-mode, the first fluid (F1) can be fed to the expansion mechanism, so that the first fluid (F1) can be conveyed to a second heat exchanger (WT2) after loading by the expansion mechanism, and preferably, the first fluid (F1) is not fed to the expansion mechanism, so that the first fluid (F1) can be fed to the second heat exchanger (WT2) after bypassing the expansion mechanism (EO).

Description

technical field [0001] The invention relates to a circulation system for commercial vehicles, such as trucks or buses. Background technique [0002] figure 1 A circulation system 100' for a commercial vehicle according to the prior art is shown. The cycle system 100' comprises: a first cycle 10' which conducts a first fluid F1' and which implements a so-called refrigerant cycle; and a second circuit 20' which conducts a second fluid F2' and which implements For a so-called coolant circuit. [0003] The first cycle 10' includes a condenser / gas cooler and an evaporator with an expansion valve preceding it. The condenser / gas cooler and the evaporator are arranged in the roof system of the commercial vehicle. The first circuit 10' also includes a further evaporator, to which the expansion valve is likewise upstream. A further evaporator is arranged in the front box of the commercial vehicle. The first cycle 10' further comprises a compressor V' and a plurality of valves, f...
