YingTengExplosion-proof multi-split air conditioning unitsOperates normally under the following environmental conditions:
a) Altitude not exceeding 2,000m.
b) Applicable environment: temperature -7℃ to 43℃, free of corrosive gases.
c) There are explosion hazard areas formed by mixtures of flammable gases, vapors, and air in groups II A, II B, IIC, and T1 to T4.
Explosion-proof multi-split air conditioners are a type of central explosion-proof air conditioning units, commonly referred to as "one-outside-to-many-insides." This means a single outdoor unit is connected through piping to two or more indoor units. The outdoor side utilizes wind-cooled heat exchange, while the indoor side employs direct evaporation heat exchange, forming a refrigerant air conditioning system. The multi-split system is increasingly widely used in medium and small buildings, as well as certain public buildings.
Compared to traditional central air conditioning systems, multi-split central air conditioning systems feature the following characteristics:
Energy-efficient, with low operating costs.
Flexible control, reliable operation.
Good compatibility with various units; wide range of cooling and heating temperatures.
High design flexibility, easy installation and billing.
Explosion-proof multi-split air conditioners have significant advantages over traditional air conditioners: They incorporate a new concept, integrating advanced technologies such as multi-split technology, intelligent control, multiple health technologies, energy-saving technology, and network control. These features meet consumers' demands for comfort and convenience.
Explosion-proof multi-split air conditioners require less investment compared to multiple explosion-proof units, utilizing only one outdoor unit for easy and aesthetically pleasing installation, with flexible and convenient control. They offer centralized management for all indoor units through network control. An individual indoor unit can be started separately, or multiple units can be activated simultaneously, providing greater flexibility and energy efficiency. These explosion-proof multi-split air conditioners occupy minimal space. Just one outdoor unit can be placed on the roof, featuring a compact, attractive, and space-saving design.
Long piping, high drop. Explosion-proof multi-split air conditioners can be installed with ultra-long piping up to 125 meters, with indoor units capable of a drop of up to 50 meters; the drop between two indoor units can reach 30 meters, making the installation of multi-split air conditioners flexible and convenient.
Explosion-proof multi-split air conditioning systems offer a variety of indoor unit options, allowing for customizable styles. Compared to traditional central air conditioning, they avoid the issue of simultaneous operation and high energy consumption, making them more energy-efficient. Additionally, their automated control eliminates the need for dedicated machine rooms and dedicated personnel, as required by conventional central air conditioning systems. Another feature of the explosion-proof multi-split central air conditioning is the intelligent network system, which allows a single outdoor unit to power multiple indoor units. It can be connected to a computer via its network terminal interface, enabling remote control of the air conditioning system from the computer, fulfilling the modern information society's pursuit of centralized and intelligent control.
Suitable for explosive gas environments in Zones 1 and 2.
2. Suitable for IA, IIB, IIC, and explosion-proof gas environments.
3. Suitable for environments with temperature categories T1 to T4.
4. Suitable for hazardous areas prone to fire and explosion such as scientific research, oil extraction and refining, chemical industry, battery storage, paint rooms, pharmaceuticals, factories, power substation, and warehouses, with a large applicable space.
The "YingTeng" explosion-proof multi-split air conditioning series has been specially processed with explosion-proof technology, making it suitable for use in flammable and explosive areas in Zones 1 and 2. It is widely applicable in research, oil, chemical, pharmaceutical, and power plant environments where IIA, IIB level T1 to T4 combustible gases, steam, and air mixtures pose explosion hazards. These explosion-proof multi-split air conditioners are ideal for spaces requiring temperature control. The YingTeng explosion-proof multi-split air conditioners have passed inspections by the National Quality Supervision and Inspection Center for Explosion-Proof Electrical Products and have been issued explosion-proof certification and CCC certification. They feature an attractive appearance, reasonable design, and are easy to install and maintain. The entire series utilizes brand-name compressors, microcomputer intelligent control, digital display, and boasts low noise, stable performance, simple operation, and safety. They are highly favored in the market.
