Concept and operating principle
Industrial air conditioning cools water or air by evaporating a refrigerant, usually gas. The system capacity is much greater than that of residential air conditioners. For large factories with many machines operating and people coming and going continuously, the article presents industrial air conditioning as a more optimal solution than installing multiple wall-mounted air conditioners. [1]
VRV central air conditioning system
VRV stands for “Variable Refrigerant Volume” and is manufactured and distributed by Daikin. The system is suitable for high-rise buildings and facilities with large usable areas and limited space for installing separate outdoor units. It consists of 1 high-capacity outdoor unit connected to multiple indoor units; typically, 1 to 1 several outdoor units are connected to all the indoor units in 1 building. According to the article, Daikin invented the central air conditioning system more than 20 years ago. [1]
Features of the VRV H central air conditioning system
The source introduces Daikin VRV H central air conditioning, the VI generation, with a 2024 range of 2-way cooling/heating products. The specifications listed include refrigerant piping up to 190m long, a maximum height difference of 110m, 7 indoor unit styles, and an IP55 sealed electrical components box. The system features automatic refrigerant charging, refrigerant-cooled Inverter modules, defrosting before shutdown, and VRT Smart II control. Daikin also provides software to support product selection and heat load calculations. [1]
VRF central air conditioning system
VRF stands for “Variable Refrigerant Flow”. The system is similar to VRV but uses the VRF designation to distinguish it from Daikin’s system. VRF can adjust the flow rate of circulating refrigerant, thereby varying capacity according to the external load. The article describes this system as providing cooling and heating for large spaces, with high energy efficiency and a compact design; the product lines mentioned include vrf Toshiba, VRF Mitsubishi, VRF GREE, VRF Panasonic, VRF Trane, vrf Hisense and vrf Aqua. [1]
Packaged Air Conditioner
Packaged air conditioners have high capacity and airflow and are commonly used in factories, restaurants, halls, large offices, and shopping mall lobbies with false ceiling heights above 4 meters. The source describes 3 types: floor-standing direct-blow, concealed ceiling-ducted, and cabinet ducted. The direct-blow type delivers cool air from the indoor unit into the room; the concealed type distributes cool air through a duct system; the cabinet ducted type places the indoor unit under the floor, making the return-air filter easy to clean and the unit easy to maintain. It is suitable for dusty factories such as textile mills, garment factories, and electronic component manufacturing plants. [1]
Chiller Central Air Conditioning
A chiller supplies chilled water as the cooling medium, with water temperatures stated in the article as ranging from 6 – 30 degrees. According to the source, this system is not yet widespread in Vietnam but is familiar in Western countries. The products listed include the HTS/WSC Chiller, HTV Chiller, Daikin Chiller HXE, and DAIKIN Chiller WME/WMC. [1]
Application spaces
Industrial air conditioning is used for large projects, factories, production areas, office buildings, villas, hotels, and resorts. For hotels, villas, and offices, VRV or VRF systems allow each room to use an indoor unit suited to its needs. For production facilities, the article mentions the use of ducted Packaged systems. [1]
