The invention discloses an off-grid type photovoltaic direct-driving air-conditioning device which comprises an off-grid type photovoltaic power generation system, a driving motor system and a heat pump system, wherein the off-grid type photovoltaic power generation system is electrically connected with the driving motor system and is used for supplying power to the driving motor system; the heatpump system comprises an air-conditioning compressor, a water cooling condenser, a throttle valve and a water cooling evaporator which are communicated through pipelines; a refrigerant is circulated inside the pipelines; the driving motor system is used for driving the heat pump system and used for driving the compressor of the heat pump system to act up. By adopting the off-grid type photovoltaicdirect-driving air-conditioning device disclosed by the invention, the defects that a conventional photovoltaic air conditioner needs to be inspected and approved when being mounted, needs mounting and maintenance quality and is high in field requirement and poor in reliability are overcome, the mounting concern of photovoltaic air conditioners of the civil market is eliminated, electronic and mechanical energy balance functions are achieved, popularization and application of the photovoltaic air conditioners are facilitated, and the purposes of energy conservation and environment protectionare achieved.
Description
technical field [0001] The invention relates to a photovoltaic air conditioner, in particular to an off-grid photovoltaic direct-drive air conditioner. Background technique [0002] In hot summer, the power consumption of air conditioners is close to one-third of the power consumption of the entire power system, and summer is the season with the strongest solar radiation energy. Therefore, it is natural and reasonable to apply solar radiation energy to air conditioning refrigeration choose. If solar air-conditioning can be widely used, it will greatly reduce the consumption of conventional energy, and it is a necessary measure to protect green mountains and green waters and build a beautiful home. [0003] Solar photovoltaic modules can directly convert solar radiation energy into direct current, and have significant advantages such as no noise and long service life. Therefore, photovoltaic air conditioners are an important direction for the development of solar air conditi...
