eClim, straightforward cooling for stretch and plaster ceilings

Cooling by a surface, not by a draught

Conventional air conditioning cools the air and blows it back into the room. A cooling ceiling lowers the temperature of its own surface, which then absorbs the radiation of people and surfaces. The mechanism is the exact reverse of radiant heating.

What the absence of blowing changes

No fan noise, no cold draught on the neck, no dust set moving again. That is the most frequent complaint made about air based systems, and it disappears along with the vehicle that produced it.

The physical limit to know

A surface cannot go below the dew point of the surrounding air without causing condensation. That limit sets the cooling output available and it cannot be got round, whatever equipment is installed.

Why the control watches the humidity

The dew point depends on temperature and on humidity. Correct control measures both and raises the surface set point when the air takes on vapour, which protects the ceiling and the installation.

What the system does not do

It does not dehumidify. Direct expansion air conditioning dries the air by condensing on its cold coil; a cooling ceiling specifically avoids that phenomenon. In a humid climate, ventilation therefore remains a subject in its own right.

The two possible substrates

Stretched fabric or plasterboard. The principle is identical, the difference lies in the inertia of the facing and the response time, exactly as for the heating version of the same system.

The physical principles are developed on the dedicated page, and the network on the distributors page.
