KaRo Systems

Radiant Heating & Radiant Cooling

A New Concept in Air Conditioning

Natural, silent and without draft.

An experience technique: the radiant/convection ceiling.

The function of the KaRo Capillary Tube System was inspired by the Human Body. The water circulates inside a mat formed by capillary tubes. As the human body uses the blood circulation to regulate its temperature, the water of the KaRo Capillary Tubes System irrigates the building with temperature of:

16˚C (60˚ F) and 40˚C (105˚ F).

The KaRo Capillary Tube System refreshes room temperature by radiation and convection. A wall or ceiling temperature of 20˚C (68˚F) is enough to cool natural, silent and draft free way. The considerable rate of efficiency is obtained by the use of water as the cooling fluid, allowing very large energy savings!

The provisions of the energy laws recently implemented throughout Europe offer a partial explanation for the current interest in the implementing of energy efficient measures and technologies in building construction in Europe.

It is obvious that a similar result cannot be obtained in the US without serious re-examination of current building standards.

So far, market control by the compressor-driven technology, preconceptions of the public, and the difficulty of overcoming traditional building practices have serious barriers to the adoption of radiant cooling in the United States.

In Europe is perfect example of demonstrating the opportunities to alternative cooling technologies by government commitment to energy efficient.

Power Point

Why use Radiant Cooling?

Air Conditioning Systems of Today

Most air conditioning systems use the same principle of forced air. In forced air systems, warm room is circulated, chilled and blown back into the space. With the increased use of computers and other office technology, higher and higher heat loads need to be removed from these environments.

To remove this additional heat, a higher volume of cooler air is blown into the working environment to maintain comfort, making draft-free cooling with chilled, primary air increasingly more difficult. An additional problem that came to light in the 1970’s and 1980’s is known as:

“sick building syndrome”

The standard forced air cooling system can carry the airborne spores to other locations in the building. Forced air systems can also expose occupants throughout a building to odors and cold viruses or contribute to "sick building problems".

This high level of recirculation promotes the spread of potentially harmful and/or odor causing organisms.

The Benefits!

Save Energy! Smaller more efficient chiller

Indoor Air Quality! Not paying for over ventilating

Zoning Capabilities! Utility room requires less space

Piping is not Insulated Testing & balancing made simpler

Integration fire suppression Reduced maintenance cost & operating cost

No Noise-No Draft!

Hydronic radiant cooling technology enables air conditioning to occur in a completely different way-a way that solves both problems. Radiant capillary tubes drywall ceiling or acoustical ceiling system that contains chilled water running through the capillary tubes that are bonded to back side of the surface.

The ceiling drywall or acoustical ceiling systems function as heat exchangers between the room air and the chilled water.

The ceiling absorbs heat from heat sources in a room and exchanges it with the circulating chilled water.

The chilled water is then pumped to a chiller, re-cooled, and returned to the ceiling.

KaRo may be applied on Wall, Floor or Ceilings, and given that the Architect has a greater flexibility to gain ceiling height without having the "cross over duct work".

What about Condensation?

Condensation of water occurs when dew point is reached, proper water temperature and with the aid of fresh ventilation (to meet law requirements) the surface panel or drywall will remove sensible heat from the space (cooling) system.

The Ventilation system not only ensures the requirement level but also regulates the latent or moisture load of the space;

Keep in mind that the airflow required is small relative to conventional cooling system.

For extra security each zone or space has a dew point sensor, if a risk of condensation is present the cooling (chilled water) is reduced either by closing the control valves, switching off the pumps, or raising the supply water temperature to control dew point!

The principal advantages of radiant panel heating systems are listed in Chapter 6 of the 1996 ASHRAE Handbook as:

	Ø Comfort levels can be better than those of other conditioning systems because radiant loads are treated directly and air motion in space is at normal ventilation levels.
	Ø Space conditioning equipment is not needed at the outside walls, simplifying the wall, floor and structural systems.
	Ø Almost all mechanical equipment may be centrally located, simplifying maintenance and operation.
	Ø No space is required within the air conditioned room for mechanical equipment. This is especially valuable in hospital patient rooms and other applications where space is at a premium, where maximum cleanliness is essential, or where it is dictated by legal requirements.
	Ø Draperies and curtains can be installed at the outside wall without interfering with the space conditioning system.
	Ø Cooling and heating can be simultaneous, without central zoning or seasonal changeover when four pipe systems are used.
	Ø Supply air quantities usually do not exceed those required for ventilation and dehumidification.
	Ø The modular KaRo Capillary Tube Mats concept provides flexibility to meet changes in partitioning.
	Ø A 100% outside air system may be installed with less severe penalties in terms of refrigeration load because of reduced air quantities.
	Ø A common central air system can serve both the interior and the perimeter zones.
	Ø Wet surface cooling coils are eliminated from the occupied space, reducing potential for septic contamination.
	Ø KaRo Capillary Tube Mats can use the automatic sprinkler system piping (see NFPA standard 13, Chapter 3, Section 3.6). The maximum water temperature must not fuse the heads.
	Ø KaRo Capillary Tube Mats heating and cooling and minimum air quantities provide a draft-free environment.
	Ø Peak loads are reduced as a result of thermal energy storage in the panel structure, exposed walls, and partitions.
	Ø KaRo Capillary Tube Mats can be coupled with other conditioning systems for heat loss (gain), compensation for cold or hot floors, windows, etc.
