Ceiling Cooling
JUPITER Ceiling Cooling
It is well known that warm air rises and cold air falls, so radiant cooling systems make sense to be installed at ceiling level. Providing a source of chilled water is the task of a heat pump running in reverse.
Underfloor heating pipework can also be used for cooling; however, your choice of floor finishes must be carefully considered. There is a risk that condensation can form on cooled floors, resulting potentially in damage and a risk of slipping. It is therefore important that the dewpoint and relative humidity are kept in check. Luckily there are some simple ways around this problem, such as dew point sensors.
An environmentally friendly alternative to air conditioning
Our experience from previous projects has demonstrated that chilled ceiling systems can offer on average a 5° C reduction in air temperature when the temperature outside starts reaching the late twenties, even without humidity control. There is additional perceived comfort offered by a reduction in the radiant temperature of the building fabric and furniture in the space.
Mechanical Ventilation with Heat Recovery systems (MVHR) assist in keeping steady Relative Humidity (RH) levels which reduces condensation risk.
Cooling Source
Ideally you will require a reversible heat pump to provide chilled water for the underfloor heating circuits in the summer months. Modern thermostatic control systems can receive a changeover signal from the heat pump, reversing thermostat operation so that the individual circuit valves are opened when the thermostat detects that the room is hotter than the setpoint temperature. Compatible heat pumps should be able to send heating/cooling signals to thermostat wiring centres.
Condensation Prevention
In order to avoid condensation, all components leading from the cooling source to the ceiling system are lagged. Our modular cooling manifolds are manufactured from glass fibre reinforced polyamide and fitted with IMI automatic flow regulators. All flow and return pipework leading to ceiling circuits come as pre-insulated PE/RT pipe.
Dewpoint sensors can be fitted to protect the entire system.
Installation
Based on the original Ideal panel system, the JUPITER ceiling system is simply attached to a standard MF ceiling system set at 250 mm centres using a proprietary clip system. Once installed and pressure-tested, the system can be closed with either a ceiling product such as Knauf Thermoboard or equivalent.
