| 摘要 |
<p>A combined refrigerant heating and cooling system comprises a compressor (118), an outside heat exchanger (110), an inside heat exchanger (116), a refrigerant-to-engine coolant heat exchanger (124), at least one refrigerant expansion device (112) and at least one redirection device (120), wherein the arrangement is such that said compressor (118) is switchable between a heat pump loop and a cooling loop by means of said redirection device (120), said heat pump loop comprising said inside heat exchanger (116), said refrigerant expansion device (112) and said refrigerant-to-engine coolant heat exchanger (124), and said cooling loop comprising said outside heat exchanger (110) and said inside heat exchanger (116). According to the invention, the outside heat exchanger (110) is arranged in such a way that an outlet of said outside heat exchanger (110) is connected to a connection point of said heat pump loop which in heat pump mode lies downstream of said refrigerant expansion device (112), e.g. between said refrigerant expansion device (112) and said refrigerant-to-engine coolant heat exchanger (124). <IMAGE></p> |
