Ventilation device and power equipment

Abstract

The invention relates to the technical field of ship power equipment and particularly relates to a ventilation device and power equipment. The ventilation device comprises a cabin, a first air supply assembly, a second air supply assembly, a first control assembly and a second control assembly, wherein an air supply outlet of the first air supply assembly extends into the cabin and supplies air to an air inlet of an internal combustion engine, and the first control assembly is electrically connected with the first air supply assembly so as to control the air supply amount of the first air supply assembly; an air supply outlet of the second air supply assembly extends into the cabin and supplies air into the cabin, and the second control assembly is electrically connected with the second air supply assembly so as to control the air supply amount of the second air supply assembly. The power equipment comprises the ventilation device. According to the ventilation device and the power equipment, the ventilation device can ensure that adjustment of environmental parameters in a cabin is not affected by changes of combustion requirements of the internal combustion engine, and therefore the internal combustion engine can continuously and stably operate in a constant external environment.

Description

technical field [0001] The present application relates to the technical field of ship power equipment, in particular to a ventilation device and power equipment. Background technique [0002] Ships propelled by high-power diesel engines require a large engine room ventilation capacity. At present, the engine room ventilation system is configured to use the entire diesel engine room as the ventilation object, and control and adjust the ventilation volume of the engine room according to the temperature difference and pressure difference inside and outside the engine room. To achieve the purpose of energy saving. [0003] However, the configuration scheme of this cabin ventilation system has the following problems: [0004] 1. Although the temperature difference control method can ensure that the temperature rise of the cabin is less than the specified value, the timeliness of the temperature difference signal is poor, which means that the current temperature difference involv...
