The temperature uniformity and heating effect of the hot air blower are important indicators for evaluating its performance, directly related to the user experience and heating efficiency. The following is an analysis of these two aspects:
Temperature uniformity
Importance: Temperature uniformity is a key parameter of the performance of hot air blowers, especially suitable for scenarios with high requirements for temperature distribution such as greenhouses and industrial drying. If the temperature uniformity is poor, it may lead to local overheating or insufficient heating, affecting the usage effect.
Factors affecting temperature uniformity:
Fan design: High-quality fans can promote hot air circulation and enhance temperature uniformity. For instance, a hot air blower equipped with a high-temperature resistant air supply duct and a dedicated aluminum alloy fan can achieve long-distance heating with uniform temperature supply.
Temperature control system: The high-precision intelligent control system can precisely adjust the temperature and reduce fluctuations. For instance, some hot air fans can reach temperatures above 100℃, and they have high temperature control accuracy, which can maintain a stable heating environment.
Equipment structure: The hot air circulation type hot air blower reduces heat loss and improves temperature uniformity by circulating hot air.
Measurement and Standards: Temperature uniformity is usually evaluated by measuring the temperature differences at multiple points within the workspace, generally within ±2℃, and for high-precision equipment, it can reach ±0.5℃.
Heating effect
Heating speed: Heating speed is an important indicator for evaluating the performance of a hot air blower. The hot air blower with PTC ceramic graphene spray heating technology can generate heat within 1 second of startup and raise the room temperature within 3 minutes, making it suitable for scenarios that require rapid heating.
Thermal conversion efficiency: The thermal conversion efficiency of high-efficiency hot air fans can reach over 85%, quickly converting electrical energy or other energy sources into thermal energy and reducing energy waste.
Heating range: The heating range of the hot air blower is related to factors such as wind force and the design of the air outlet. For instance, some hot air blowers can have a wind force of up to 2.225m/s, and the hot air can be felt from about three meters away, making them suitable for large-scale heating.
Purchasing suggestions
Select according to the usage scenario:
For household use: Choose a hot air blower that heats up quickly, has low noise and good temperature uniformity, such as the model with PTC ceramic spray graphene heating technology.
For industrial or greenhouse use: Select a hot air blower with hot air circulation function, high temperature uniformity and wide heating range to meet the heating demands of large areas and high requirements.
Pay attention to the temperature control system: Give priority to choosing a hot air blower equipped with a high-precision intelligent control system, which can precisely set and control the outlet air temperature, improving the heating efficiency and comfort.
Check user reviews: By reviewing the reviews of other users, understand the temperature uniformity and heating effect of the hot air blower in actual use, and avoid purchasing a product with poor performance.
