The air-conditioning electric heater and the central air-conditioning system are integrated. Before the central air-conditioning system works, it is heated by circulating water to increase the temperature of the water. During and before the operation of the air-conditioning system, the heating effect and working effect of the air-conditioning system will be improved. So, what is the basic principle of electric heater?
When modular central air conditioning units are used, the heating effect of the host is closely related to the ambient temperature. When the ambient temperature is very different from the standard operating temperature (outdoor temperature is 7°C), the thermal efficiency of the host will be greatly reduced, and the temperature of the provided room will be very different from the required temperature of the room.
When the ambient temperature is lower than 4°C, it will cause difficulty in starting the host. Even if it is reluctant to start, it is easy to cause the danger of compressor liquid impact and oil injection, which greatly reduces the service life of the air conditioning unit under long-term severe working conditions. At this time, it is necessary to configure the central air-conditioning electric heater to preheat the water medium to increase the water temperature. It not only ensures the normal startup and operation of the air conditioning unit, but also improves the heating efficiency and heating effect of the host.
The above is the basic principle of electric heater, I hope it can be helpful to everyone.
