Design Flexibility

The VRV IV W series can meet various air conditioning needs by taking full advantage of the characteristics of a water cooled system.

Adaptable to high-rise buildings due to easy installation on each floor

Compact outside units can be easily installed in the machine rooms on each floor. This helps overcome the restriction on differences in height of refrigerant piping. Individual air conditioning can be easily provided in high-rise buildings using this VRV system.

Easy to install in underground shopping malls and subway systems

Individual air conditioning can be easily provided in underground shopping malls, subway systems, etc. using this VRV system because heat exchanging with outdoor air is not required.

Also recommended for condominiums and detached houses

We offer an extensive lineup of small capacity outside units as well as connectable residential indoor units for detached houses. Compact outside units can be installed indoors.

Renovation of an Air Conditioning System

Rising problems for old, conventional water system

Why is renovation necessary?

  1. As equipment ages, its air conditioning capacity weakens with each passing year.
  2. With frequent breakdowns in the outside unit, normal use of air conditioners is unachievable.
  3. The maintenance cost for the equipment keeps rising.
  4. The longer the equipment serves, its noise becomes louder.
  5. Scale formed in water pipes is hard to clean, accelerating corrosion and aging processes.
  6. Meeting the requirements of a 24-hour running IT room is out of the question.
  7. Catering to new tenants’ partitioning changes in a timely manner is difficult.
  8. Charging by household is not possible.
  9. Serving tenants working overtime is difficult.
  10. Central control and management costs too much.
Troublesome issues in renovation?

A Flexible System, Convenient for Expansion/Renovation

Problems with existing water systems can be solved with minimal construction work.

 

1. Indoor installation solves the puzzle of proper placement of outdoor units

The outside units of the water cooled VRV IV W series don’t have necessity to direct heat exchanging with outdoor air. This feature makes it possible to place the outside unit inside the building, which greatly extends design flexibility and makes it easier to adapt to different types of buildings and open to various kinds of creative building exteriors.

2. Part of the old system can be retained for cost reduction

The water cooled VRV IV W series can retain the cooling tower of the old system during renovation, effectively keeping costs down.

3. The compact outside units facilitate the renovation process and saves space for the outside unit area

The outside units of the water cooled VRV IV W series are conveniently compact, which not only enables transport by elevator possible, but also effectively simplifies installation. This also saves a great deal of time and labor.

The modular design featured by the water cooled VRV IV W series enables a free and flexible configuration of the outside units. Outside units can be arranged with one on top of another, saving space for other purposes.
