Guangdong Yujingfengexplosion-proof Air Conditioner
Product Description
Internationally renowned brand compressors
The compressor is known as the heart of an air conditioner, and its performance directly determines whether the air conditioner can have good overall performance. Yujingfeng explosion-proof air conditioners adopt compressors from famous brands such as Meizhi and Lingda. These high-performance compressors, integrating decades of technical expertise, significantly improve cooling and heating efficiency while effectively reducing noise.
Ultra-low noise system
With a minimum noise level of only 20 decibels, the air conditioner adopts multiple noise reduction measures including an integrated silent air duct design, a large-diameter unequal-pitch cross-flow fan, and a rare earth permanent magnet silent motor.
Automatic defrosting
The intelligent defrosting system initiates defrosting timely based on the frost accumulation level. Compared with ordinary air conditioners, it achieves more thorough defrosting, higher energy efficiency, and enhanced safety.
Independent dehumidification
The air conditioner automatically adjusts its operating mode, with the indoor unit running at a low speed to condense moisture in the air into water droplets, maintaining dry and comfortable indoor air.
Product Overview
Explosion-proof air conditioners can be divided into cooling-only and cooling & heating types by performance. By structural form, they are classified into split-type wall-mounted explosion-proof air conditioners, split-type cabinet explosion-proof air conditioners, and window-type explosion-proof air conditioners, etc.
Based on high-quality branded air conditioners, explosion-proof air conditioners are designed in compliance with the requirements of the GB3836 series standards. They undergo explosion-proof processing using special manufacturing techniques and methods.
Features of Explosion-proof Air Conditioners
Flameproof structure with strong corrosion resistance, especially suitable for corrosive and explosive gas environments.
Equipped with internationally renowned brand compressors for stable and reliable cooling/heating performance, low noise, and long service life.
Adopts composite explosion-proof protection, combined with comprehensive overheat and pressure protection measures.
All functional statuses are displayed on an illuminated LCD screen for clear and intuitive viewing.
Adjustable temperature and air volume.
This product features cooling, heating and automatic defrosting functions. Key components such as the compressor and fans are specially treated for explosion protection, realizing full-unit explosion-proof performance. It is applicable to flammable and explosive mixed gas environments including petroleum, chemical, pharmaceutical, scientific research, military, and hazardous warehouse sectors. Structurally, it adopts composite explosion-proof technologies such as flameproof type, intrinsically safe type, and encapsulation type. The control terminal is fully controlled by intrinsically safe circuits, which do not generate any electric sparks, ensuring convenient and safe operation. The high-efficiency multi-fin heat exchanger enables fuller contact between refrigerant and air, greatly improving the cooling and heating effect of the air conditioner. Both manual and remote control modes are available.
Product Manufacturing Standards
The whole unit adopts international ultra-weak current technology isolated intrinsically safe circuits, manufactured and processed for explosion protection via special techniques. The design and production of the product strictly comply with the following national standards:
GB3836.1-2010: Explosive atmospheres—Part 1: Equipment—General requirements
GB3836.2-2010: Explosive atmospheres—Part 2: Equipment protected by flameproof enclosures "d"
