Abstract

The invention discloses a renewable energy refrigeration system and a method. The system comprises a refrigeration system, a renewable energy storage system, and a control system, the refrigeration system comprises a compressor, a first heat exchanger, a first fan, a throttling device, a second heat exchanger, and a second fan, the renewable energy storage system comprises a solar photovoltaic assembly or a wind wheel, and a storage battery, and the control system comprises a temperature sensor and a controller. According to the renewable energy refrigeration system and the method, solar or wind power generation is directly employed to drive the refrigeration system to operate, the consumption of electric supply for refrigeration is not needed, the refrigeration energy consumption is greatly reduced, emergency cooling standby cold sources can be provided for power failure, and the stability of the system is higher.

Description

technical field [0001] The invention relates to a renewable energy refrigeration system and method, belonging to the technical field of air-conditioning engineering. Background technique [0002] From a national perspective, China is a country rich in solar energy resources, and the total radiation is roughly between 930-2330 kWh / square meter / year. The annual average daily radiation in most areas is above 4kWh / ㎡, and the highest in Tibet is 7kWh / ㎡. Generally speaking, more than two-thirds of the regions in our country have good solar energy resources, especially the Qinghai-Tibet Plateau, Xinjiang, Gansu, and Inner Mongolia, where the conditions for utilizing solar energy are particularly favorable. In addition, my country is rich in wind energy resources, and the wind energy reserves that can be developed and utilized are about 1 billion kW, of which, the wind energy reserves on land are about 253 million kW (calculated from the height of 10m above the ground on land), and...
