COLD CIRCUIT

摘要

The invention relates to a cold circuit (1) comprising a compressor (2), a gas cooler (3), an internal heat exchanger (4), an expansion element (5), an evaporator (6) and, optionally, an accumulator (7). The accumulator (7) is arranged in the low pressure part of the cold circuit (1). The average density of the coolant in the cold circuit (1) has a maximum of 260 kg/m³ +/-10%. The volume of the accumulator (7) is obtained, preferably, approximately by the formula V_Akku = [m_Leckage- V _KKL (P_{max_}
