Central air conditioner VRV is the best “air conditioning” in the market today with many advantages over other brands in the market. The central air conditioning system becomes very important and familiar to us when building large projects such as office buildings, villas. It plays an important role in bringing luxury, convenience. as well as cost savings for users.
The development as well as increasingly improving quality to consumers, central air conditioning system VRV has been born so far over 30 years with four generations VRV I, II, III, IV.
VRV central air conditioning system consists of 4 types:
VRV bare ceiling casstle
VRV ceiling air duct connection
VRV set the floor
Wall mounted VRV
Constructing a VRV air conditioning system
– With equipment: outdoor unit, indoor unit, pipeline system and accessories
– Outdoor: outdoor unit is a large copper tube heat exchanger, internal aluminum wing has a axial fan layout. Motor compressors and auxiliary equipment of the cooling system located in the outdoor unit. Refrigeration compressors are usually centrifugal type winding coils
– Indoor: The indoor unit has many types as the indoor unit of the air conditioner. An outdoor unit is not fixed with some indoor units, as long as the total capacity of the indoor units fluctuate between 50 ÷ 130% of the outdoor unit capacity. Generally VRV systems have a number of indoor units ranging from 4 to 16 staging.
– The outdoor unit and the indoor unit are a copper tube and control wire. Copper pipes in this system are larger than removable air conditioners. Copper pipes are connected by means of specialized couplings called REFNETs
– The system is equipped with micro-control (PID) to control the temperature of the dust filter room
– The system has two groups of magnetic island and inverter and heat recovery (Heat recovery). Reconditioned VRV heaters can work in 2 heating and cooling modes.
Highlights of the central air conditioning system VRV
A outdoor unit can be connected to many different indoor units: one outdoor unit can be connected to 32 indoor units.
It is possible to place the outdoor unit on the terrace to increase the aesthetics of the building because of the gas pipeline connecting the outdoor unit – the indoor unit up to 1000m.
Power savings are among the highest in all refrigeration lines. With a COP of> 4.6, that means 1 kW of electricity produces 4.6 kW of cold.
The outdoor unit works with the same capacity as the indoor unit. We should note: The lowest heat exchanger is 10% / total outdoor unit capacity
With outstanding advantages
Energy saving
Accurate localization and inverter technology minimize power consumption for optimum energy savings.
Adaptable design
Outdoor module design and a variety of indoor refrigeration systems ensure that the system is designed to fit the space needed to install.
Local control
The VRV system allows temperature control of individual areas to provide maximum comfort for buildings.
Flexible in layout
As a result of the heat dissipation, the system can be installed anywhere and requires no additional equipment such as water cooling systems (water pumps, cooling towers etc. are required).
High security
With the ability to connect to the fire alarm of the building, in the event of a fire occurs automatically disconnect the power either in the area or the building.
In addition, the system does not use large air ducts, thus limiting the spread of fire and the spread of smoke in the event of a fire.
Save on installation and commissioning costs
Gas pipelines connecting the outdoor unit and the indoor unit are simply copper tubes with very small cross-sections so as to minimize the installation costs.
Saving operating costs through the use of varying the flow of the system in the system through adjusting the compressor’s operating frequency, thus achieving high efficiency while operating, saving on operating costs. of the system.
