Solar-assisted absorption refrigeration device for refrigerated truck

Abstract

The invention relates to a solar-assisted absorption refrigeration device for a refrigerated truck. The solar-assisted absorption refrigeration device comprises a first heat supply system, a second heat supply system and a refrigeration system; the refrigeration system is connected with the first heat supply system and the second heat supply system through wires and pipelines correspondingly; the first heat supply system comprises a solar cell panel, a controller and a storage battery; the second heat supply system comprises an engine water tank, a circulating water pump and an adjusting valve; and the refrigeration system comprises a generator, a condenser, a heat exchanger, an evaporator, an absorber, an expansion valve, a solution pump and a throttling valve. The bottom of the generator is provided with a heater band. According to the solar-assisted absorption refrigeration device for the refrigerated truck, refrigeration cycle in a compartment of the refrigerated truck is completed by reasonably using engine waste heat and the solar power generation technology, and the refrigeration device is simple in structure, easy to achieve, environmentally friendly and free of pollution; in addition, the solar-assisted absorption refrigeration device still can refrigerate the interior of the compartment of the refrigerated truck when the refrigerated truck stops in the halfway or stops at night, the delivery range of the refrigerated truck is expanded, the limitation that the refrigerated truck needs to be connected with an external power source when stopping is eliminated, and the solar-assisted absorption refrigeration device can refrigerate the compartment all the time.

Description

technical field [0001] The invention belongs to the fields of solar power generation, engine waste heat recovery and absorption refrigeration, and in particular relates to a solar-assisted absorption refrigeration device for refrigerated vehicles. Background technique [0002] In recent years, with the rapid development of the national economy, the improvement of people's living standards and the change of lifestyle, people's demand for fresh food and quick-frozen food has gradually increased, which has greatly promoted the development of cold chain logistics. As a key link in logistics, the demand for it is increasing day by day. In 2010, the National Development and Reform Commission promulgated the "Development Plan for Agricultural Products Cold Chain Logistics". The construction of chain logistics system encourages enterprises to transform and purchase cold chain processing equipment to ensure that storage and transportation links can meet market demand.

[0005] Related patents applying absorption refrigeration technology to automobiles: Chinese patent (CN103542602A) discloses an engine-based solar absorption refrigeration system and a solar refrigerated vehicle, which is realized by converting solar energy into heat to drive the refrigeration system and the waste heat recovery technology of automobile engines Refrigeration function, but it uses solar energy - thermal energy and engine waste heat are transferred to the generator by the heat pipe, the heat source utilization rate is low, and because there is no thermal energy storage device, especially when it is stopped halfway on a rainy day, there is no solar energy. Converted into heat energy, refrigeration cannot be realized at all, and refrigerated vehicles are greatly restricted
