Capillary mat cooling system - an air conditioning alternative
Air Conditioning

Not a fan of air conditioning?

If you don’t like you air conditioning blown through ducts or don’t like the look of air conditioning indoor units, there is now a new more comfortable method of air conditioning using capillary heating and cooling mats. Also, installing capillary mats in the ceiling is less costly compared to underfloor hydronic heating and hydronic radiators. 

The capillary mat cooling system can be easily retrofitted to existing buildings and provide builders and architects with considerable design flexibility for energy-efficient and cost-conscious construction. Capillary heating and cooling mats ensure energy-saving and a pleasant indoor temperature in all types of buildings including family homes and offices.

Capillary heating and cooling mats are manufactured from soft tempered copper tubing with aluminium fins for excellent thermal conduction and long life.

Technique – how it works

Mats are made up of capillary tubes and installed in a closed loop system of thin tubes. These tubes are connected to the hydronic heating and cooling circuit, powered by a reverse cycle heat pump, with either hot or cold water flowing through the capillary tubes regulating the room temperature. 

In heating mode, the system will operate best with the water temperature at around 40 degrees. In cooling mode, the system water will be above the dew point to avoid condensation.

The system can be powered by solar energy from roof top panels.

Installation

In the installation of the heating and cooling mat system, all materials must be non-corrosive, to avoid causing sludge which may lead to system malfunction. Materials such as plastic, stainless steel, copper, brass and red brass can be used with the capillary system.

How the heating and cooling mats are regulated?

In cooling reverse/cooling mode, the heat pump is governed by a dew point guard to ensure that it supplies cold hydronic water above the dew point temperature, typically around 16 degrees.

In heating mode, the heat pump only needs to supply warm water (not hot water) between 35 to 40 degrees, which is an easy task for a heat pump so it uses less power. Also, this warm temperature is easier for valves and fittings and avoids overheating the ceiling.
