Container energy-storage variable-frequency air conditioning unit for direct-current power supply ship

Abstract

The invention discloses a container energy storage variable-frequency air conditioning unit for a direct-current power supply ship. The air conditioning unit comprises a direct-current power supply access port and a compressor module. The direct-current power supply access port is electrically connected with the compressor module, the compressor module comprises a compressor and a direct-current to alternating-current conversion device electrically connected with the compressor, and the direct-current to alternating-current conversion device is used for converting a direct current into an alternating current and transmitting the alternating current to the compressor. The direct-current power supply access port is arranged to access a direct-current power supply to the air conditioning unit, and the direct-current to alternating-current conversion device is arranged to convert the direct current into the alternating current and transmit the alternating current to the compressor so thatpollutant emission is effectively reduced, and a noise is low; and the alternating current output by the direct-current to alternating-current conversion device is only supplied to the compressor so that the demand for the alternating current is small, the size of the corresponding direct-current to alternating-current conversion device is small, the direct-current to alternating-current conversion device can be integrated in the air conditioning unit, independent arrangement is not needed, a space of the container is not occupied, and a space utilization rate of the container is effectively increased.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a container energy storage variable frequency air conditioner unit for ships with direct current power supply. Background technique [0002] Shipping in my country's coastal and inland river basins has an important impact on my country's economy. With the development of shipping, container energy storage and power supply ships have become the main ship type for coastal and inland waterway shipping. [0003] Specifically, a lithium battery is usually installed inside the container as an energy storage device for energy storage. However, the energy storage device is prone to heat during charging and discharging. Therefore, a corresponding air conditioner needs to be installed in the container to cool down the energy storage device and maintain a stable operating environment temperature of the energy storage device. [0004] At present, the air conditioner...
