Disclosed is a cold accumulation type heat insulation box provided with a cold accumulation tank. A condenser is arranged on the top of the front end of the outside of the refrigeration heat insulation box, the cold accumulation tank for storing low-temperature heat is arranged at the front end of the interior of the refrigeration heat insulation box, and a cold accumulation system of the cold accumulation tank is independent. The cold accumulation type refrigeration system arranged at the front end of the interior of the refrigeration heat insulation box provides energy for a refrigeration unit of a refrigerator car through conversion between solid state and liquid state of cold accumulation liquid in the cold accumulation tank, cold does not need to be generated through the energy of an engine, fossil energy is saved, and pollution to the ecological environment caused by fossil energy is prevented at the same time. When the internal temperature of the cold accumulation type heat insulation box reaches a set temperature value, the cold accumulation type refrigeration system can store cold; when the internal temperature of the cold accumulation type heat insulation box does not reach the set temperature value, the cold accumulation type refrigeration system releases stored cold, so that constant temperature of the interior of the cold accumulation type heat insulation box is guaranteed.
