What is a Trench Cooler?
A trench cooler is – similar to a trench heater - water-based and placed under the floor. This results in increased floor space without compromising human comfort. It includes an inner cold-water pipe with fins providing convective cooling to the surrounding air. Trench coolers are available as 2-pipe solutions or more commonly a combi-trench system based on a 4-pipe solution altering heating or cooling depending on room occupancy and outdoor weather. Trench cooling is often seen as a supplement to other room cooling and is used to avoid drafts and improve the indoor environment as to temperature and air quality.
Trench cooling is getting more and more used in cubicles, hotels, restaurants or any other modern commercial buildings.
How is a Trench Cooler Application Optimized?
With proper balance, a trench cooler or a trench combi-unit may reduce cooling or cooling/heating costs by up to 20% while protecting the indoor climate and increasing people comfort. FlowCon recommends three different solutions to a trench cooler installation:
1. Trench Coolers with Pressure Independent Control (PICV)
The PICV will react to system pressure changes and regulate the flow of water to required flow by adjusting the actuator position. This helps the system to be accurately controlled even with pressure changes and reduced loads.
FlowCon recommends the following PICVs:
2. Trench Coolers with Temperature Control (TCV)
The TCV will react to system pressure changes and automatically provide the selected max. flow independent of pressure changes. In addition, the actuator will provide ON/OFF control, securing proper thermal performance always, even at partial loads.
FlowCon recommends the following TCV:
3. Trench Coolers with Automatic Balancing (ABV)
The automatic balancing valve will react to system pressure changes and limit the flow of hot or cold water to required max. flow helping the system to be accurately controlled even with pressure changes. This solution may be installed with the separate control valve.
FlowCon recommends the following ABVs:
