What is the reason why Delong f3000 warm air is not hot? There is something wrong with the heating system, and the reason why the water temperature can't come up.
The basic working principle of the heating system: the low-temperature heat medium is heated in the heat source, and after absorbing heat, it becomes a high-temperature heat medium (high-temperature water or steam), which is sent into the room through the pipeline, and the heat is released through the heat dissipation equipment to raise the indoor temperature; After heat dissipation, the temperature is reduced to become a low-temperature heat medium (low-temperature water), and then it is returned to the heat source for recycling through the recovery pipeline. In this way, the heat of the heat source is continuously sent to the room to supplement the indoor heat loss and keep the indoor temperature at a certain level. 1, small heater water tank blocked:
The car heating system is not used for a long time, and it may not be hot to use warm air in winter. The main reason is that the small warm air tank is blocked. After the small warm air tank is blocked, hot water does not pass through the small water tank, resulting in the phenomenon that warm air cannot be generated. The blockage of the small heating tank may cause cold air to blow out, which is caused by the owner's long-term failure to replace the antifreeze. If the air conditioning duct is not cleaned for a long time, it is easy to block the small warm air tank. It is suggested that car owners should make a comprehensive maintenance of the car's heating system before winter comes.
2. The heater control panel is damaged:
The heater control panel is damaged, just like the light bulb control switch at home. When the owner turns on the heater switch, because the heater switch fails, the corresponding heater power supply signal cannot be transmitted, resulting in the phenomenon that the heater is not hot. If the heater is not hot due to the switch of the heater, the owner needs to go to a professional repair shop or a 4s shop for treatment.
3. There is gas in the waterway:
There is air in the waterway, which leads to insufficient hot air supply and abnormal warm air. There is gas in the waterway, which will not only make the warm air not hot, but also lead to other faults caused by the high temperature of the engine, which needs to be dealt with by the owner in time. If he can't handle it himself, it is recommended to find a professional maintenance person to handle it.
