Refrigeration system having to transport means in order to improve the capacity of a heating cycle.

摘要

Refrigeration system for the transport (10), comprising a compressor (16), a condenser (34), a receiver (42), an evaporator (58) and a cell (62), and a control valve (22) with the outlet orifices of the cooling and heating (28, 30) which are connected alternately to the first or second cooling circuit (31, 82) in order to trigger the cycles of the cooling and heating, respectively. The heating capacity of a heating cycle the control is improved, before switching to the heating cycle, for connection of the outlet orifice (44) of the receiver (42) to the second cooling circuit (82), while maintaining the orifice of the cooling of the control valve (28) which is active in the first refrigerant circuit (31) for a predetermined period of time (98).
