Problems solved by technology

It must be used in gaseous form after being gasified. Since the temperature of LNG is -162°C, it will generate a lot of cold energy during the gasification process. If it is not recovered, it will cause a lot of energy waste
[0003] However, most of the existing refrigerated vehicles use oil to generate electricity, and the electric drive compressor is used for cooling, without the function of cold storage. After the temperature inside the refrigerated compartment reaches the set temperature, the compressor has to stop for five minutes every five minutes of operation, while the generator must continue to operate. Power generation, leading to high cooling costs and wasted energy

Abstract

The invention relates to a refrigeration and cold accumulation system for a refrigerator car. The system is mainly designed for solving the problem that an existing refrigerator car is high in refrigeration cost. The system comprises a plurality of cold accumulation pools, coil pipes of the cold accumulation pools are connected with LNG inlet and outlet pipes, Freon inlet and outlet pipes and cooling medium inlet and outlet pipes respectively, the LNG inlet pipe is communicated with an LNG cylinder, and the LNG outlet pipe is connected with an engine. The Freon storage tank is connected with aFreon pipeline A, the Freon inlet pipe is communicated with the Freon pipeline A, the Freon outlet pipe is communicated with a Freon pipeline B, and the Freon pipeline B is connected with the Freon storage tank through a condenser, a filter and a compressor. The cooling medium inlet pipe is communicated with a cooling medium pipeline A, and the cooling medium pipeline A is connected with an outlet of a first independent refrigeration evaporator through the filter; and the cooling medium discharge pipe is communicated with a cooling medium pipeline B, and the cooling medium pipeline B is connected with an inlet of the first independent refrigeration evaporator through an expansion kettle. The system has the advantage that: refrigeration cost is low.

Description

Technical field: [0001] The invention relates to a refrigeration cold storage system for a refrigerated vehicle. Background technique: [0002] With the rapid development of the natural gas industry, the use of liquefied natural gas as a vehicle fuel has developed rapidly. LNG is obtained from the liquefaction of gaseous natural gas through cryogenic processing, and is an ultra-low temperature energy-carrying liquid. It must be used in gaseous form after being gasified. Since the temperature of LNG is -162°C, it will generate a lot of cold energy during the gasification process. If it is not recovered, it will cause a lot of energy waste. [0003] However, most of the existing refrigerated vehicles use oil to generate electricity, and the electric drive compressor is used for cooling, without the function of cold storage. After the temperature inside the refrigerated compartment reaches the set temperature, the compressor has to stop for five minutes every five minutes of o...
