The invention relates to the technical field of
natural gas vehicles, in particular to a parking warm air
system of a gas vehicle and a parking warm air control method. The parking warm air
system comprises a gas tank, a
combustion chamber and a fan
assembly, wherein the fan
assembly is used for conveying air to the
combustion chamber; the air supply pipeline is used for circularly supplying air into the vehicle room, and a heat exchange channel is arranged between the air supply pipeline and the
combustion chamber; the temperature sensor is used for monitoring the real-time indoor temperature of the vehicle; and the control
assembly is used for adjusting the opening degree of the
electromagnetic valve and the
gas supply rate of the fan assembly according to the real-time temperature of the vehicle, the target temperature and the pressure parameter in the gas tank.
Natural gas is directly extracted from the gas tank, and
direct combustion is carried out through the
combustion chamber, so that the heating requirement of a driver during rest is met. Furthermore, according to the warm air
system, the opening degree of the
electromagnetic valve and the rotating speed of the fan can be adjusted according to the pressure in the
fuel gas tank, and sufficient combustion and even heating of
fuel gas parking warm air are achieved.
