Temperature

• High temperature environment: Prolonged exposure to high temperatures can accelerate the aging of the insulation material of the electric heating wire. At the same time, high temperature will increase the resistance of the electric heating wire, which leads to more heat generation, further accelerating the damage of the electric heating wire and shortening its service life.
• Low temperature environment: Under low temperature conditions, the flexibility of the electric heating wire will decrease and become more prone to breakage. For example, for electric heating wires used outdoors in cold weather, if appropriate insulation measures are not taken, the insulation layer is prone to rupture when subjected to external tension or bending, thereby affecting the performance and service life of the electric heating wire.

Humidity

• Frequent changes in humidity: Frequent changes in environmental humidity can cause the insulation material of the electric hotlines to expand and contract. For example, when the humidity increases, the insulation material absorbs moisture and expands; When the humidity decreases, it will lose water and shrink again. This repeated expansion and contraction can cause stress inside the insulation material, which over time can lead to cracks and delamination in the insulation material, damaging its insulation performance and affecting the service life of the electric heating wire.

Chemical substances:

• In environments with corrosive chemicals such as acid, alkali, salt, etc., the metal wires and insulation materials of electric heating wires will be corroded. For example, acidic substances can react chemically with metal wires, causing rust and corrosion on the metal surface, resulting in a decrease in the conductivity of the wire and an increase in resistance. At the same time, corrosive substances can also damage the structure of insulation materials, making them fragile and losing their insulation protection function, thereby shortening the service life of electric heating wires.

Mechanical stress:

• If the heating wire is in an environment that is susceptible to mechanical vibration, impact, or tension, it can cause damage to it. For example, in some industrial equipment, the electric heating wire may vibrate with the operation of the equipment, and long-term vibration can cause fatigue fracture of the wires inside the electric heating wire. In addition, when the electric heating wire is stretched or squeezed by external forces, it will cause deformation of the internal structure, resulting in poor contact between the wires, increased resistance, and thus affecting the heating effect and service life of the electric heating wire.

• Reasonable selection: Select a temperature controller with appropriate specifications and performance based on factors such as temperature range, control accuracy requirements, load type and size in actual application scenarios. For example, for high-precision laboratory temperature control, a temperature controller with high-precision sensors and advanced control algorithms should be selected; For ordinary household air conditioners, a temperature controller with high precision is generally sufficient to meet the needs.

• Standardized installation: Strictly follow the installation instructions of the thermostat to ensure the correct installation position and avoid installation in environments with high temperature, humidity, vibration, or strong electromagnetic interference. The temperature sensing element should be installed in a position that accurately reflects the controlled temperature, in full contact with the controlled object or medium, and securely installed to prevent loosening or displacement. For example, when installing the temperature sensing probe of a refrigerator thermostat, it should be placed in a suitable position inside the refrigerator to accurately measure the temperature inside the box.

• Correct wiring: Carefully check the wiring diagram of the thermostat to ensure that the power line, sensor line, output control line, etc. are connected correctly and firmly, avoiding problems such as misconnection, virtual connection, or short circuit.

Research has shown that under different climatic conditions, this thermostat can save 11% to 54% of energy and has a shorter payback period.

• Low energy residential buildings: In low-energy residential buildings, the energy-saving potential of intelligent temperature controllers is also worth paying attention to. For example, in low-energy residential buildings in cold climates, installing smart radiator valves and conducting simulation analysis shows that smart thermostats can save energy according to different usage situations. Although people stay away from home relatively short due to the large time constant of buildings, smart thermostats can shorten the time for temperature drop and improve energy efficiency by implementing measures such as preheating in advance, high insulation, heat recovery ventilation, etc.

• Oilfield central air conditioning system: In the oilfield central air conditioning system, by modifying the air conditioning control system, adding power metering equipment and artificial intelligence AI algorithms, time-sharing temperature control can be achieved, which can effectively reduce idle power consumption and achieve the effect of personnel comfort and equipment energy saving.

Closely related: Collaborative creation of precise temperature

The correlation between temperature controller and heating wire is the key to precise temperature control. The thermostat provides a "smart brain" for the heating wire, determining when it works and when it stops. When the thermostat detects that the ambient temperature is below the set lower limit, it will send a signal to turn on the circuit of the heating wire, causing the heating wire to start working, generate heat, and increase the ambient temperature; When the temperature rises to the set upper limit, the thermostat will cut off the circuit, causing the heating wire to stop heating and avoid excessive temperature. This close coordination not only achieves precise temperature control, but also greatly improves energy utilization efficiency. For example, in smart electric heaters, the collaborative work of temperature controllers and heating wires enables the electric heater to adjust heating power in real time according to indoor temperature, ensuring indoor warmth and avoiding energy waste.

However, it should be noted that the price of electric hotlines is not only determined by the power output, but also influenced by various factors such as material, brand, and quality.

Select high-efficiency heating materials:

• Graphene: It has ultra-high thermal conductivity and carrier mobility, and can quickly convert electrical energy into thermal energy. In low-temperature environments, its excellent electrical properties can rapidly raise the temperature of the heating film, reducing the heating delay caused by low temperatures. For example, the application of graphene heating film in some high-end warm clothing can quickly provide warmth to the human body in cold weather.
• High performance carbon fiber: Not only does it have high heating efficiency, but it can also generate far-infrared radiation that is beneficial to the human body. In low-temperature environments, carbon fiber heating membranes have good stability, and far-infrared radiation can promote blood circulation in the human body, indirectly improving the insulation effect and enhancing overall heating efficiency.

Strengthen insulation measures:

• Add thermal insulation layer: wrap thermal insulation materials around the heating film, such as polystyrene foam, polyurethane foam, etc., to reduce heat loss to the low-temperature environment. For example, when using heating film for underfloor heating, laying insulation board under the heating film can effectively prevent heat from transferring downwards, allowing more heat to stay in the indoor space and improving heating efficiency.
• Improve spatial sealing: For spaces using heating membranes, such as rooms, equipment enclosures, etc., enhance their sealing. Install sealing strips, double-layer glass, etc. to reduce the penetration of cold air and minimize heat loss caused by air convection. In the cold winter, a well sealed room can better maintain the heat generated by the heating film and improve the actual efficiency of its use.

Intelligent temperature control:

• Adopting high-precision temperature controller: Equipped with a high-precision temperature controller, it can more accurately sense temperature changes and adjust the working status of the heating film in a timely manner. In low-temperature environments, the thermostat can accurately control the power output of the heating film based on the slight difference between the set temperature and the actual temperature, avoiding excessive or insufficient operation of the heating film due to inaccurate temperature control and improving heating efficiency.

Adapt to suitable power sources:

• Stable voltage output: For AC powered heating films, select the appropriate power frequency based on their material characteristics and design requirements. The appropriate frequency can make the electronic movement inside the heating film smoother, the current distribution more reasonable, and thus improve the heating efficiency.
