Solar injection and compression integrated refrigeration system for dual temperature refrigerated trucks

Abstract

The invention discloses a solar ejection and compression integrated refrigeration system for a dual temperature refrigerated truck. The solar ejection and compression integrated refrigeration system comprises a main refrigeration system, an auxiliary refrigeration system and a heating system which are arranged in the dual temperature refrigerated truck; the main refrigeration system comprises a cold storage refrigeration system and a freezing refrigeration system; a cold storage evaporator of the cold storage refrigeration system and a freezing evaporator of the freezing refrigeration system are connected between a shunt and a current collector in parallel; the heating system comprises a cold storage heating system and a freezing heating system; a cold storage heating device corresponds to the cold storage evaporator; a freezing heating device corresponds to the freezing evaporator; the freezing heating device and the cold storage heating device are connected between a water tank and a circulating pump in parallel; and the auxiliary refrigeration system comprises a solar ejecting system and an auxiliary compression system. According to the solar ejection and compression integrated refrigeration system disclosed by the invention, temperature sensors are separately arranged in a cold storage chamber and a freezing chamber and are respectively used for detecting the temperature in the cold storage chamber and the temperature in the freezing chamber; and the control over the temperature of the cold storage chamber and the temperature of the freezing chamber is facilitated, and cold storage and freezing effects are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of energy-saving systems for refrigerated vehicles, and in particular relates to a refrigeration system integrated with solar energy injection and compression for dual-temperature refrigerated vehicles. Background technique [0002] With the development of the national economy and the improvement of people's living standards, food preservation has attracted the attention of the whole society. The cold chain of food has been formed in our country, and the transportation volume of refrigerated food has been greatly increased. As an important transportation tool for food preservation, it The share in the society reflects the level of refrigerated storage in a country. Refrigerated trucks have the advantages of wide practicability, strong flexibility, less transit links, and point-to-point transportation. Therefore, refrigerated transportation is particularly important. On the other hand, due to the shortage of ...

Problems solved by technology

Different types of agricultural products have different storage and transportation temperatures. At the same time, various small-batch demand patterns make refrigerated vehicles in a single temperature zone in a half-storage state, resulting in energy waste and increased transportation costs.
