Solar air conditioner and power supply method thereof

Abstract

A power supply method of a solar air conditioner includes: controlling a photovoltaic cell set to power the air conditioner, and monitoring output power of the photovoltaic cell set in real time; if the detected output power of the photovoltaic cell set is smaller than a set value; controlling an internal electrical storage device to supplement power supply so as to co-power the air conditioner with the photovoltaic cell set. The output power of the photovoltaic cell set is monitored in real time to allow the photovoltaic cell set to provide the air conditioner with stable power supply. If the detected output power of the photovoltaic cell set is smaller than the set value, the internal electrical storage device is controlled to supplement power supply so as to co-power the air conditioner with the photovoltaic cell set. Therefore, sudden power failure of the air conditioner caused by sudden failure or causes of a solar module or the photovoltaic cell set is avoided causing unavailability of the air conditioner, and damage of the air conditioner caused by abnormal start and stop is also avoided.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a solar air conditioner and a power supply method for the air conditioner. Background technique [0002] Nowadays, the requirements for environmental protection and intelligence of household or vehicle electrical equipment such as air conditioners are getting higher and higher, so solar air conditioners have been developed to meet customers' requirements for environmental protection. However, the efficiency of the existing solar air conditioners is relatively low and cannot meet the requirements well. And the existing solar air conditioner is generally equipped with an inverter to invert the DC power output of the photovoltaic cell group into AC power, which supplies power to the air conditioner, which further reduces the utilization efficiency of solar energy, and the use of the inverter makes the entire solar air conditioner larger in size. , and due to the large volume of the inverter, t...

However, the efficiency of existing solar air conditioners is relatively low and cannot meet the requirements well

And the existing solar air conditioner is generally equipped with an inverter to invert the DC power output of the photovoltaic cell group into AC power, which supplies power to the air conditioner, which further reduces the utilization efficiency of solar energy, and the use of the inverter makes the entire solar air conditioner larger in size. , and due to the large size of the inverter, the inverter and the air conditioner can only be installed separately, which is extremely inconvenient to install, and due to the limitation of the installation space of the car, it cannot be installed and used on the car

Since the solar module, inverter, and air conditioner are installed separately, the wiring is cumbersome, and installation and maintenance are extremely inconvenient

[0003] Especially for the vehicle environment, the stability of solar power supply is poor. If the solar panel temporarily fails or is not smooth due to various reasons, it will not be able to supply power to the air conditioner, which will cause the air conditioner to suddenly stop working due to power failure. In some cases, the air conditioner has to be restarted to work, and the sudden power failure often causes the air conditioner to stop abnormally and easily damage the air conditioner, which seriously affects the service life of the air conditioner
