Abstract

The invention provides a refrigeration equipment using a natural gas as a refrigerant. The refrigeration equipment using the natural gas as the refrigerant is characterized by comprising a refrigeration roller and a base, the refrigeration roller is arranged above the base, one side of the refrigeration roller is communicated with an air duct, the air duct is obliquely arranged upwards, a safety valve is arranged at the top of the refrigerating roller, and supports are fixed on the two sides of the lower part of the refrigeration roller. The refrigeration equipment using the natural gas as therefrigerant has the following advantages that the refrigeration equipment can be adjusted according to needs, convenient to use, firmer in structure, simple in structure, convenient to disassemble and assemble and longer in service life.

Description

technical field [0001] The invention belongs to the field of refrigeration equipment, in particular to a refrigeration equipment using natural gas as a refrigerant. Background technique [0002] A semiconductor cooler, also called a thermoelectric cooler, is a heat pump. Its advantage is that there are no sliding parts, and it is used in some occasions where the space is limited, the reliability is high, and there is no refrigerant pollution. Utilizing the Peltier effect of semiconductor materials, when direct current passes through a galvanic couple formed by two different semiconductor materials in series, heat can be absorbed and released at both ends of the galvanic couple, which can achieve the purpose of cooling. It is a refrigeration technology that produces negative thermal resistance, is characterized by no moving parts, and is relatively reliable. Existing refrigeration equipment using natural gas as a refrigerant has a single refrigeration module with low effici...
