Cold storage system for transport

A system for maintaining a chilled temperature in a cold storage with a roof and a base, the system comprising:

• a plurality of coolant arrays uniformly placed on the bottom of the roof of said cold storage;
• each coolant array comprising multiple coolant plates arranged in rows and columns in a rectangular configuration;
• a compressor generating airflow and being positioned on the bottom of the roof to direct the airflow from a first side of the roof across the plurality of coolant arrays to a second side of the roof and from the second side of the roof towards the base so as to create circulating airflow in a circular pattern from said roof to said base in said cold storage;
• said plurality of coolant arrays being placed relative to said compressor such that the airflow generated by the compressor causes freezing of the coolant arrays and the circulating airflow maintains the temperature in said cold storage in a range from −25° C. to +25° C.;
• a coolant holder frame configured to facilitate uniform adjustment of said multiple coolant plates in said plurality of coolant arrays, and allow for efficient airflow from top to bottom in said storage;
• wherein the base of said cold storage at least partially defines a plurality of channels extending along the base which are configured to pass the air circulated by said compressor and increase the circulation of airflow in said cold storage;
• and, wherein said cold storage is insulated to increase the thermal insulation coefficient to maintain the desired temperature in said cold storage;
• and
• wherein the system is configured to have efficient circulation of airflow in the entire cold storage once the coolant arrays are frozen even when the compressor is stopped afterwards.
