Alternating current and photovoltaic direct current dual purpose manual control cooling air conditioner

Abstract

An alternating current and photovoltaic direct current dual purpose manual control cooling air conditioner is composed of three parts including a cooling air conditioner device, an alternating currentand direct current dual purpose power device and an alternating current and direct current dual purpose power supply converting device. A cooling air conditioner on an automobile is composed of fiveparts including a compressor, a condenser, an evaporator assembly, a liquid storage dryer and a throttling device which are connected through hoses. The alternating current and direct current dual purpose power device is composed of an alternating current and direct current dual purpose series motor, a belt pulley and an electromagnetic clutch on the compressor. The alternating current and directcurrent dual purpose power supply converting device is composed of an alternating current and direct current dual purpose output 12 V switching power supply, an alternating current and direct currentdual purpose motor converting switch blade and a direct current arc restraining switch blade. According to the alternating current and photovoltaic direct current dual purpose manual control cooling air conditioner, an automobile air conditioner assembly is adopted, the size is small, the efficiency is high, the automobile air conditioner assembly is shakeproof, photovoltaic direct current is adopted, arc striking cannot occur, ordinary alternating current can also be used, energy is saved, and using is convenient. The alternating current and photovoltaic direct current dual purpose manual control cooling air conditioner is suitable for being used in a house where direct using photovoltaic power generating is established.

Description

[0001] This application is a divisional application of the invention patent application with the application number: 2015101699643, the invention name: AC and photovoltaic DC dual-purpose manual control cold air conditioner, and the application date: March 31, 2015. Technical field [0002] The invention relates to a household appliance, in particular to an AC and DC dual-purpose cold air conditioner. Background technique [0003] At present, the known household air conditioners are all powered by alternating current. The air conditioners on automobiles are small in size and high in efficiency, and are not afraid of vibrations, but the compressors of automobile air conditioners are driven by automobile engines. In order to save energy and protect the environment, the relevant units have been gradually promoting my patent "Household Dual-track Power Supply No Use, Less Use, Direct Use System" (ZL201220245052.1), which is now referred to as "Direct Photovoltaic Power Generation...

Problems solved by technology

[0004] In order to overcome the problem that the contacts of the switch are blown and stuck due to arcing when using high-power DC motors for automobile air conditioners, this problem is solved by using a switch knife. , in the existing AC motor, the rotor is a coil, the stator is permanent magnet and excitation, most of them can also be used when using 180V to 220V DC, but the series excitation motor is the first choice, and the series excitation motor is an AC and DC dual-purpose motor. Therefore, it is also called a general-purpose motor, with a power ranging from several hundred watts to several thousand watts, suitable for air conditioners of various sizes
