![]() ![]() In combination with the ekinex® actuatorscontrollers for HVAC functions, the device allows a complete independent climatization for each room or zone, adding to the function of controller for heating and cooling the possibility to effectively control the dehumidification and humidification of the rooms. Thanks to the calculation of the dew temperature, it is possible to carry out active strategies to protect against the formation of condensation when using radiant panel systems for summer cooling. The relative humidity measurement significantly expands the room air conditioning functions and increases the comfort and safety of the room. The optional Delégo supervision (not shown in the diagram) allows you to monitor and control the entire home automation system through an App for smartphones. This optimization makes it possible to increase the operational safety of the system, closing the circuits involved by means of the zone valve (8) if the thermohygrometric conditions should cause the beginning of condensation on the cooled surfaces. Dehumidification is activated when the relative humidity measured by the room thermostat (E) exceeds the threshold value predefined in the system design (for example: 50%).Ī sensor (10) to detect the formation of condensation during cooling operation can be connected to the room thermostat (E). Cooling integration is activated when the temperature measured by the room thermostat (E) exceeds the setpoint value by a predefined offset value (for example: 1.5 ☌). The contacts for the start / stop of the cooling integration (2) and dehumidification (3) are activated by the binary output EK-FE1-TP (C). If necessary, an additional NTC temperature sensor (F) can be connected to the room thermostat (E) to carry out adjustment based on a weighted average temperature value.Īt the seasonal switchover to cooling mode, the actuator-controller (D) closes the seasonal valve (5) to avoid feeding the towel warmers with cold heat transfer fluid. In heating or cooling mode, at the request of the thermostat, the actuator-controller EK-HE1-TP (D) controls the opening of the zone valve (8) of the radiant ceiling. The room thermostat EK-EQ2-TP (E) measures temperature and relative humidity and is installed in a position exposed to the air flow generated by the machine (1). The EK-TM1-TP time / astronomical digital switch (A) ensures that the system is allowed to operate according to predefined time scheduling and is constantly synchronised with date and time by the GPS module (optional) EK-GPS-1 (B). The installation is typically made in a central position with respect to the served zone, for example recessed in the false ceiling in the hallway or in the corridor. In the residential sector, for example, it is common to use one machine for the living zone and a second one for the night zone. Usually these machines do not serve a single room, but several rooms or an area of a building. In this case, moreover, they are complete machines for the air handling of the rooms, able to support the operation of the system in summer cooling, also performing the functions of dehumidification (with reduction of the cooling latent load) and handling of part of the sensible cooling load. This particular system is a combined system it combines the ceiling radiant panels with one or more units for energy recovery ventilation (ERV), whose basic function is the renewal of the room air with high efficiency heat recovery. The radiant ceiling system shown in the example is used to heat and cool the rooms of a residential building. As in the case of the floor radiant system, the ceiling radiant panels only handle the heat loads of a sensible type in general, the ceiling solution offers a higher yield in cooling. The system is invisible and uses the whole surface of the ceiling as a large terminal for the thermal exchange prevailing at radiation. In residential applications, the false ceiling has a plasterboard finish towards the rooms, suitable for civil buildings, and an insulation layer towards the top. The heat transfer fluid circulates inside circuits made up of metal or plastic pipes integrated in a suspended false ceiling the series of panels are fed by distribution manifolds installed above the circuits served. The ceiling radiant system is a hydronic system for room heating and cooling, which was added to the floor version over time in common it maintains the characteristic of having a low temperature difference between the heat transfer fluid and the room air. ![]()
