Description

technical field [0001] The invention relates to an application technology of solar energy in the field of air conditioning, in particular to a control device and a control method for a solar air conditioner. Background technique [0002] Existing solar technology is basically based on lighting and large-scale power generation projects; the application of power supply for air conditioners is also to convert solar energy into AC power and then convert it into DC power twice. Due to the additional inverter, the efficiency is low; at the same time It needs to be synchronized with the mains, and the circuit is complicated; the effect of using a separate network is not good when there is no sun. [0003] Chinese Patent Document No. CN2665593Y disclosed on December 2, 2004 a solar energy and AC mains dual-power air-conditioning system, which includes an air-conditioning system body and a power supply. The body includes compressor, condenser, throttling device, evaporator, pipeline...
