Heating, ventilation and/or air conditioning loop for e.g. electric motor vehicle, has expansion member and outer heat exchanger provided in secondary line, where secondary line is arranged between bypass points arranged on primary line

摘要

The loop (8) has a compressor (9), an inner heat exchanger (12), an expansion member (17) and an evaporator (13) that are arranged in a primary line (26) along a flow direction (11) of coolant e.g. R134a coolant, at interior of the loop. A secondary line (27) is arranged between bypass points (29, 30) arranged on the primary line. Another expansion member (18) and an outer heat exchanger (15) are provided in the secondary line. One of the bypass points is located between the compressor and the evaporator. An independent claim is also included for a heating, ventilation and/or air conditioning system comprising a case.
