Functional use of parking heater
1. Warm up the engine
The heater can preheat the engine, avoid the wear and tear caused by the cold start at low temperature, and protect the engine. In addition, the heater can preheat the engine in the off state, saving fuel. The reasons that affect fuel consumption are related to the external environment. The low temperature outside the car has higher fuel consumption, and the high temperature outside the car corresponds to lower fuel consumption.
2. Driving and parking heater
We passed the actual living test. Compared with the overhead air conditioner of the RV, the fuel heater noise is lower and the noise is within our acceptable range. Furthermore, the fuel heater can be used independently and is not affected by the external environment.
3. Heating domestic water
Throughout the heating process of the heater, the coolant always circulates in the sealed coolant pipeline, which is safe and convenient. The fuel heater is equipped with a one-button start device, which is convenient and quick to operate. The ratio can be adjusted by the adjustable tap of cold and hot water, and the heating and cooling are automatically controlled.
Solve the problems of winter RV heating, bath water heating, water tank antifreeze, and engine preheating
4. Water heater function
The working principle of the water heater: the heater heats the antifreeze, the heated antifreeze is pumped to the heat exchanger of the hot water tank, the antifreeze transfers heat to the water in the water tank through the heat exchanger, and the cooled antifreeze flows back to the heater Be heated again. In this way, the water in the water tank is gradually increased through heat transfer. The rising speed of the water temperature is related to the power of the heater, and the area of the radiator is related to the volume of water that needs to be heated.
Water heater work simulation
1. Anti-freezing function of heating and water tank
Heating and water tank antifreeze principle: The parking heater heats the antifreeze, and the heated antifreeze is pumped to the radiator, and the antifreeze radiates heat through the radiator to increase the air temperature in the RV. The antifreeze with residual heat flows to the antifreeze system of the water tank, and the radiator or metal pipe is used to heat the water tank to maintain the temperature of the air, thereby realizing the antifreeze function.
2. Simulation of heating and water tank antifreeze work
(1) Preheat engine function
The principle of preheating the engine: the parking heater heats the antifreeze, and the heated antifreeze is pumped to the engine cylinder block. The heated antifreeze quickly transfers heat to the cylinder block, then quickly cools down and returns to the heater to achieve The effect of heating the engine.
(2) Use the engine heating function
Principle of using engine heating function: After starting the engine heating function, the heater stops heating, and the engine's "high temperature antifreeze" flows through the heater, radiator and antifreeze device in turn. The antifreeze fluid flowing from the engine is in the temperature range of 90℃-100℃, which not only saves energy, but also improves the heating effect.
(3) Use the engine water heater function
The working principle of using the engine water heater: After starting the engine heating function, the heater stops heating, and the "high temperature antifreeze" of the engine flows through the heater, radiator and antifreeze device in turn. The antifreeze liquid flowing from the engine is at 90℃-100℃, which saves energy and improves the heating effect.
Heater maintenance and self-check
In order to use the parking heater normally in winter, the heater self-check and maintenance work before the coming of winter should be done before using the motorhome, as follows:
For those using timer or remote control, if the heater cannot start normally, please check whether the timer or remote control battery is charged, whether the remote control distance between the remote control and the car is exceeded, and whether there is an obstacle blocking the radio signal. In addition, you should also check whether the car battery is losing power.
For the mobile phone APP control, if the heater cannot start normally, you need to check whether the mobile phone sending text messages and the SIM card in the heater control box are disabled (such as no balance), and whether the car is parked in a place where there is no mobile phone signal. If the mobile phone signal of the car park is poor, which affects the normal operation of the SIM in the car preheating system, it is recommended to try again after moving the car. If the problem still cannot be solved, you need to consult a technician. In addition, you should also check whether the car battery is losing power.
If the heater cannot be started or works abnormally during the heater maintenance process, please follow the procedure below for self-examination and troubleshooting:
1. Turn on the heater switch;
2. Cut off the heater's power supply (this can be achieved by unplugging the fuse or cutting off the heater's main power supply);
3. After half a minute, restore the power supply to the heater (recover the fuse or the main heater power), then restore the heater switch and then turn on the heater again.
