Electric auxiliary heat pipe heater
The basic principle of electric auxiliary heat heater:
When using a modular central air conditioning unit, the heating effect of the main unit is closely related to the ambient temperature. When the ambient temperature is different from the standard on-site temperature (outdoor temperature is 7 °C), the heating efficiency of the main unit will be greatly reduced. Low, the temperature of the room provided is quite different from the temperature that can be requested in the room. When the ambient temperature is lower than 4 °C, it will cause difficulty for the host to start up. Even if it is barely turned on, it will go through a long period of bad working condition, which will easily lead to the danger of liquid hammer and oil throwing of the compressor, and greatly reduce the service life of the air conditioning unit. At this time, it is necessary to configure the central air-conditioning auxiliary electric heater to pre-heat the water medium and raise the water temperature, which not only ensures the normal startup and operation of the air-conditioning unit, but also improves the heating efficiency and heating effect of the main unit.
Electric auxiliary heater product features:
The new pipeline heater adopts stainless steel structure as a whole, which is small in size, small in footprint, easy to move, and has waterproof design and strong corrosion resistance. The high-density thick insulation layer is used between the stainless steel inner tank and the stainless steel outer casing, which has the lowest temperature loss, maintains the hot water temperature, and saves electric energy. High-quality stainless steel 304 seamless steel pipe material The main components of the electric heating pipe are made of high-insulation magnesia powder and alloy electric furnace wire material. The advanced production equipment and technology are also used in the process, which is matched with the voltage of different countries. efficacy. Its insulation performance, pressure resistance and moisture resistance are superior to national standards, and it is safe and reliable to use. The water flow direction is designed reasonably, the heating is uniform, there is no high and low temperature dead angle, and the thermal efficiency is high. The auxiliary electric heater is equipped with a thermostat, the temperature is adjustable from 30 to 100 °C, and an additional component such as an AC contactor is required to transmit signals. It is used to control the water temperature and water shortage and over temperature protection to avoid damage to components and systems. Auxiliary electric heaters can be used in single, two or more sets according to customer requirements, which is not only safe and reliable, but also energy-saving. The electric auxiliary heater can also be equipped with an electric control box according to the customer's needs. The electrical equipment in the box adopts the Delixi or Chint brand to enhance safety and reliability. The power consumption of the auxiliary electric heater itself can be compensated for from the improvement of the efficiency of the central air conditioning unit during the heating operation, and the total power consumption is not increased much.
The role of electric auxiliary heater:
In cold areas where outdoor heating is very low, the evaporation temperature of the air heat source heat pump must be very low, and the compressor operates at a high compression ratio, which inevitably leads to a decrease in the volumetric efficiency and indicating efficiency of the compressor. In this way, the heating capacity and heating coefficient of the heat pump will decrease. A better method is to add auxiliary heat source equipment, and an auxiliary electric heater is an ideal auxiliary heat source equipment. After the auxiliary electric heater is installed, it is integrated with the central air-conditioning unit. When it is used, it can realize linkage control with the unit, pre-heating the circulating water, and improving the water temperature, which not only ensures the normal start and operation of the air-conditioning unit, but also improves the air-conditioning unit. Heating efficiency and heating effect.
