Cold accumulation type heat insulation box provided with cold accumulation tank

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and relates to a cold storage type thermal insulation compartment of a cold storage tank. technical background [0002] Refrigerated trucks are key equipment in an important link in low-temperature cold chain logistics. The refrigerated truck generally includes a carrier car for carrying. An insulated box is fixed on the upper part of the main beam of the chassis of the carrier car. The insulated box is a box that ensures the temperature of refrigerated transportation. A refrigeration unit is installed on the insulated box. The generated cooling capacity is used to ensure that the specified low temperature is maintained in the thermal insulation compartment. At present, the refrigeration principle of conventional refrigerated vehicles is to provide energy for the refrigeration unit through the engine to drive the refrigeration unit to work. This part of energy comes from the chemical energ...
