Solar air conditioning system with charging, control and power lightning-protection functions

Abstract

The invention discloses a solar air conditioning system with charging, control and power lightning-protection functions. The system comprises a solar cell, a solar controller, an accumulator and a variable-frequency air conditioner. 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 inverter circuit. The lightning protection circuit comprises sixty-first to sixty-second resistors, sixty-first to sixty-third piezoresistors, sixty-first to sixty-fourth fuses, and a gas discharge tube. The solar air conditioning system can be effective in lightning protection and improved in security performance; according to the solar air conditioning system, while the accumulator is charged, the activity of the accumulator can also be ensured, the service life of the accumulator can be prolonged, the charging efficiency of the accumulator can be improved, the power utilization time of the accumulator can be prolonged, the good self-starting capacity is provided, the appearance of an endless loop state is avoided, lightning surges suffered by the air conditioner can be absorbed, and thus the air conditioner is protected against being damaged by lightning surges.

Description

technical field [0001] The invention relates to the field of solar air conditioning, in particular to a solar air conditioning system with the functions of charging, control and power supply lightning protection. 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 pane...
