Ventilation pressurizing and temperature adjusting system of air pressure cabin

Abstract

The invention discloses a ventilation pressurizing and temperature adjusting system of an air pressure cabin. The system comprises a speed-adjustable air pump, a supercharger expansion machine, a supercharger air pump, an air heat exchanger, a heat exchanger and a three-way flow divider. The speed-adjustable air pump is a power source of the whole system, and pressure in the air pressure cabin can be changed by changing the rotation speed. The supercharger expansion machine is used for recycling ventilation pressure difference energy, driving the supercharger air pump connected with the expansion machine to work, and further changing pressure in the air pressure cabin. When the system works, air inflow and exhaust are conducted simultaneously, and dynamic balance is formed in the air pressure cabin. Inflow air and exhaust air with temperature difference pass through the air heat exchanger and the heat exchanger, and the flow of heat exchange air is adjusted by the three-way flow divider, so that inflow air of the air pressure cabin reaches required temperature. The system achieves continuous ventilation in the air pressure cabin, exhausts waste air in time and achieves recycling of ventilation pressure difference energy, the air pressure in the cabin is adjustable, and temperature of the environment in the cabin can be adjusted without extra air conditioning devices.

Description

technical field [0001] The invention relates to the technical field of air pressure chambers, in particular to an air pressure chamber ventilation pressurization and temperature regulation system. Background technique [0002] The air pressure cabin is a cabin that uses air to maintain the required pressure in the sealed cabin. The air pressure cabin is divided into two categories: the air pressurization cabin and the air negative pressure cabin. The internal air pressure is lower than the ambient air pressure. Air pressure chambers are widely used, including air pressurized oxygen chambers for medical use, emergency chambers for plateau environments, atmospheric simulation chambers for different altitude environments, and diving decompression chambers. Existing air pressure chambers use the air pump to maintain the required pressure in the chamber through the pressure regulating valve. When the exhaust gas concentration in the air pressure chamber reaches or exceeds the se...
