Cool storage refrigerator system achieving solar photoelectricity refrigeration and adsorption-type refrigeration and method thereof

Abstract

The invention discloses a cool storage refrigerator system achieving solar photoelectricity refrigeration and adsorption-type refrigeration and a method thereof. The system comprises an adsorption heat collector, a condenser, an evaporation liquid storage tank, a first evaporator, a second evaporator, a solar photovoltaic cell panel, a power supply device, a compressor, a refrigerator, eight valves, a throttling valve and a wire. In the daytime or when sunlight is sufficient, the solar photovoltaic cell panel is radiated through sunlight, generated power is supplied to the power supply device, and the power supply device drives the compressor to rotate by means of electricity energy obtained through solar conversion. At night, refrigeration can be carried out through energy adsorbed and accumulated through work media in the daytime, and a storage battery is replaced. On the condition that sunlight is unavailable for several continuous days, the power supply device can select to use power supplied by an alternating current power supply to drive the compressor. The cool storage refrigerator system and the method have the advantages that solar photoelectricity refrigeration and adsorption-type refrigeration can be combined to achieve an all-weather refrigeration function, energy is saved, and hot water used in daily life can be supplied.

Description

technical field [0001] The invention relates to a cold-storage refrigerator system, in particular to a cold-storage refrigerator system of solar photoelectric refrigeration and adsorption refrigeration and a method thereof. Background technique [0002] In recent years, the whole country has been seriously polluted, and smog frequently appears in various cities. It is imminent to adopt clean energy utilization technology. Moreover, with the accelerated development of urbanization in our country, the tension of power load is also a major problem. As a clean and sustainable energy, solar energy can not only alleviate environmental pollution, but also replace primary energy under certain conditions. It has been proven feasible in the refrigeration industry. [0003] The Chinese patent "CN101865586B" uses a solar photovoltaic DC cold storage refrigerator system to replace the use of primary energy, but the frequent charging and discharging of the battery in the system will seri...
