Solar hybrid power refrigerating device

Abstract

The invention discloses a solar hybrid power refrigerating device, and relates to a refrigerating device which utilizes the hybrid power of solar energy and fuel oil. A solar cell panel is arranged on the outer surface of a refrigerating box body, and the refrigerating box body is provided with a controlling system. The controlling system comprises a charging and discharging controller, a power switch / conversion module, a refrigerating system, a storage battery, an engine power supply and a temperature controlling module, wherein the solar cell panel is connected with the charging and discharging controller which is connected with the storage battery and the power switch / conversion module; the engine power supply and the temperature controlling module are connected with the power switch / conversion module; and the power switch / conversion module is connected with the refrigerating system. According to the invention, the solar energy is converted into electric power, and the fuel oil power generation, the fuel oil mechanical force and the like are utilized as a supplementary energy by combining other power energy plans, so that the hybrid power system is formed by combination of the solar energy and the fuel oil under the condition of insufficient solar power.

Description

Technical field: [0001] The invention relates to a refrigerating device utilizing solar energy and fuel hybrid power, in particular to a solar hybrid refrigerating vehicle. Background technique: [0002] A refrigerated truck is a means of transportation used for low-temperature storage or low-temperature food preservation, such as refrigerated transport vehicles, refrigerated train carriages, refrigerated cargo transport compartments, etc. It is used to transport food that needs to be kept fresh at low temperature, such as meat, fruit, chemicals, items that are easily deteriorated by temperature, special items, etc. [0003] The temperature in the refrigerated compartment is generally designed to be relatively low. For example, a meat refrigerated truck generally needs to keep the temperature inside the compartment at minus 15 degrees Celsius, or even minus 20 degrees Celsius. In this case, the temperature difference between the inside and outside of the cabin is determined...

AI Technical Summary

Problems solved by technology

[0004] Generally speaking, the use of fuel-powered refrigeration for cooling will bring technical problems to the system due to the frequent intermittent start-up of fuel-fired generators. In addition, the high cost of fuel oil will result in high transportation costs. It is necessary to find a way to provide energy for the refrigeration system. Therefore, the industry People have developed a solar refrigerated vehicle to replace the fuel-powered refrigerated vehicle

However, because solar power is affected by sunlight intensity, weather, shadows, etc., when only using solar power, the power may not be enough when the distance is long, limiting its application
