The invention belongs to the technical field of
solar energy utilization, and particularly relates to a non-storage-battery portable photovoltaic direct-driven refrigerator
system with the compressor rotation speed varying with
irradiation. The non-storage-battery portable photovoltaic direct-driven refrigerator
system comprises a photovoltaic
cell panel, a solar
irradiation sensor, a
DC voltage transmitter and a DC variable-frequency refrigerator, wherein the photovoltaic
cell panel is connected with a compressor controller; the solar
irradiation sensor and the
DC voltage transmitter are combined into a compressor speed adjusting
signal generation module; after being connected with a temperature controller in series, the compressor speed adjusting
signal generation module is connected with the compressor controller; and the output interface of the compressor controller is connected with a DC variable-frequency compressor. Compared with the prior art, the non-storage-battery portable photovoltaic direct-driven refrigerator
system provided by the invention has the following advantages: the problem that a compressor frequently starts and stops when the solar irradiation strength varies relatively greatly can be solved; the compressor rotation speed can be adjusted according to the irradiation
signal strength; the law of
energy supply and demand in an independent
photovoltaic system can be met; the energy utilization ratio and the
refrigeration efficiency are higher; and the demand for rapid
refrigeration by using a photovoltaic refrigerator in the
open air can be met.
