Heating & Cooling: What is Temperature Compensation and Dew Point Management?

TEMPERATURE COMPENSATION

WHAT IS IT?

Temperature compensation is a new style of control system which reduces running costs and increases comfort relative to previous generation thermostat based control systems.

HOW DOES IT WORK?

Rather than reacting to the current temperature in the building, turning the system on at 100% output when below set point or turning the system off completely when above set point Temperature compensation works proactively by predicting how much heat is required in the building to keep a constant temperature.  It has the ability to modulate the power of the system rather than just turn it on or turn it off.

 

WHY IS THIS BETTER?

With modern heat sources you can increase the efficiency of operation by modulating the output power back to the minimum required to achieve comfort, rather than pulsing on and off with high power it runs continuously at a much lower power, this can increase efficiency by more than 25%

It also increases comfort inside the building by eliminating overshooting and undershooting the target indoor temperature.

 

DEW POINT MANAGEMENT

WHAT IS IT?

Dew point management prevents condensation from forming on radiant cooling surfaces.

HOW DOES IT WORK?

The system measures the indoor temperature and humidity and calculates a theoretical dew point where condensation will be produced, this value is then used to set the system water temperature which is circulated to the radiant cooling system.  This is calculated dynamically and changes in real time as the indoor conditions change.

 

WHY IS THIS BETTER?

Dynamically changing the water temperature in cooling allows you to maximise the power and safety of the radiant cooling system.  If you don’t have dew point management you risk either creating condensation or lacking cooling power to adequately create comfort.
