Solar air conditioner system having functions of charging and power supply lightning protection

Abstract

The invention discloses a solar air conditioner system having functions of charging and power supply lightning protection. The solar air conditioner system comprises a solar cell, a solar controller, a storage battery and a variable frequency air conditioner, wherein the solar controller comprises a charging circuit, a control circuit, a lightning protection circuit and a discharging circuit, the variable frequency air conditioner comprises an inversion circuit, the charging circuit comprises a twenty-first diode, a twenty-second diode, a twenty-third light emitting diode, a twentieth resistor, a twenty-first resistor, a twenty-second resistor, a twenty-third resistor, a twenty-fourth resistor, a twenty-fifth resistor, a twenty-sixth resistor, a twenty-seventh resistor, a twenty-eighth resistor, a twenty-first thermistor, a twenty-second thermistor, a twenty-first triode, a twenty-first capacitor, a twenty-second capacitor and a twenty-first charging management chip, and the lightning protection circuit comprises a sixty-first resistor, a sixty-second resistor, a sixty-first thermistor, a sixty-second thermistor, a sixty-third thermistor, a sixty-one fuse, a sixty-second fuse, a sixty-third fuse, a sixty-fourth fuse and a gas discharging tube. By the solar air conditioner system, lightning can be effectively prevented, the safety performance of the system is improved, the system is convenient to install and is relatively low in cost and relatively high in reliability, a lightning surge applied to an air conditioner can be absorbed, and the air conditioner is prevented from being damaged by the lightning surge.

Description

technical field [0001] The invention relates to the field of solar air conditioning, in particular to a solar air conditioning system with charging and power supply lightning protection functions. Background technique [0002] The solar air conditioning system is composed of solar cells, controllers, storage batteries and inverter air conditioners. The existing solar air-conditioning system has the following defects: the lightning protection measures of the controller are not effective, which affects the safety performance of the system; the capacity and self-discharge of multiple single batteries of the battery are inevitably inconsistent, which affects the life of the battery. [0003] In addition, when there are several consecutive rainy days, the power of the battery is not enough to maintain the work of the powered equipment, which will affect the normal operation of the powered equipment. To solve this problem, the capacity of the battery and solar panels can be increa...

The existing solar air-conditioning system has the following defects: the lightning protection measures of the controller are not effective, which affects the safety performance of the system; the capacity and self-discharge of multiple single batteries of the battery are inevitably inconsistent, which affects the life of the battery

In thunderstorm days, the transmission line of the mains power is very vulnerable to lightning strikes. Once it is struck by lightning, a surge will occur in the transmission line of the mains power. damage
