Description

[0002] At present, the combustion head of a parking fuel air heater drives the combustion assisting air wheel and the hot air wheel to rotate synchronously. If the rotation speed of the combustion assisting air wheel is too high or too low, it will cause the fire to be blown out by strong wind or insufficient oxygen due to weak wind and incomplete combustion. When shutdown is required, the combustion assisting air wheel consumes the remaining oil at a low speed, resulting in the inability of the hot air wheel to blow cool the machine at a high rotation speed and large air volume, resulting in a long shutdown delay, which can no longer meet the heating requirements of the integrated air duct. As a result, the air volume at the far-end air outlet of the integrated air duct is weak and the heating effect is poor.

One side of the air conditioner is fixedly connected with an installation shell, and a filling block is fixedly connected inside the installation shell. An installation square plate and a fixed plug plate are arranged between the fuel parking heater and the filling block. For this kind of fuel parking heater of a bottom-mounted RV, an installation shell and a filling block are arranged on one side of the air conditioner to increase the space at the top of the air conditioner for the installation preparation of the fuel parking heater. The fuel parking heater is integrally installed with the air conditioner, reducing the installation structure investment required for installing the air conditioner and the fuel parking heater at the bottom of the RV, reducing space occupation, and ensuring the control of the use cost of the air conditioner and the fuel parking heater.
