<p>An environmentally controlled shipping container including a storage space (26), a first environmentally controlled space (34) within the storage space, a second environmentally controlled space (38) within the storage space, and a transport refrigeration unit (30). The transport refrigeration unit including a compressor (42) that provides a flow of refrigerant, a condenser (54) that receives the flow of refrigerant from the compressor, a fist evaporator (62) positioned within the first environmentally controlled space and in fluid communication with the condenser, a second evaporator (70) positioned within the second environmentally controlled space and in fluid communication with the condenser, and a pressure regulator (122) associated with the first evaporator. The pressure regulator (122) selectively restricts the flow of refrigerant from the first evaporator to the compressor such that the flow of refrigerant from the first evaporator (62) to the compressor is substantially equal to the flow of refrigerant from the second evaporator (70) to the compressor.</p> |
