Description

Parking heater and control method thereof Technical Field The application relates to the technical field of heating equipment, in particular to a parking heater and a control method thereof. Background With the continuous development of automobile technology and the increasing demands of people on vehicle comfort, parking heaters are increasingly used in the automobile field. The parking heater can provide warmth for a carriage in a vehicle parking state, effectively improve driving environment in cold weather, and can be used for preheating an engine, improving engine starting performance and reducing abrasion. In the existing parking heater, the main component is a fuel oil heat exchanger, and the fuel oil heat exchanger generates heat through the combustion of fuel oil to supply heat for users. The fuel oil combustion generally occurs in the combustor, and in the combustion process, a motor is started to drive a first impeller and a second impeller to rotate, a fuel nozzle sprays fuel oil into a combustion cavity of the combustor, an ignition plug ignites, and then high-temperature gas in the combustor is blown out of the combustor by the first impeller and enters a heat exchanger to exchange heat. The second impeller is responsible for sucking the outside air into the fuel oil heat exchanger, and discharging the outside air after heat exchange at the heat exchanger, and the discharged air becomes the air to be heated entering the parking heater.
