To achieve the best possible indoor comfort for workers, guests, patients or other users, every building is equipped with a suitable Heating and/or comfort cooling system. There are various options to increase or decrease the room temperatures and how this is controlled:
- Terminal units
- Radiator heating
- Underfloor heating
Terminal units
Among others, cover fan coil units, cooling panels and climate ceilings. These are mostly installed in the ceiling and provide a room with heating and/or cooling via a 2-, 3- or 4-pipe system. To control the room temperature, the most accurate results, in both full- and partial load conditions, can be achieved by using Pressure-Independent balancing and Control Valves (PICV). They are simply set to the required flow under full load conditions and function as automatic flow limiters. In partial load conditions, the actuator accurately reduces the flow according to needs. No overflow situation will occur, increasing the energy efficiency of the heat or cooling source.
The actuators can be controlled via a Building Management System (BMS) or stand-alone electronic room controllers. In case the terminal units contain a fan, the room controller can also be used to change the fan speed.
Radiator heating
In most cases, designed as a 2-pipe system with one or more radiators in every room. To control the room temperature, Danfoss radiator thermostats are used. They consist of a thermostatic radiator valve, mostly with a pre-setting of the design flow, and a temperature sensor. A wide variety of sensors ensure accurate control of the room temperature. For example, if curtains prevent proper measurement of room temperature, a version with remote sensor or remote sensor and control provide a better solution.
For optimal space comfort, it is recommended to equip the radiator system with an automatic hydronic balancing solution. This eliminates pressure fluctuations, thereby ensuring that the radiator thermostats function optimally.
Underfloor heating
Offers a high level of comfort by heating rooms from the floor up. The heat is spread evenly and, because it is situated in the floor, it doesn't take up any precious room space. We offer both water-based (hydronic) underfloor heating as well as electric underfloor heating solutions. It can be used to heat all spaces in the building or to only heat dedicated spaces, such as hotel bathrooms, where the comfort requirements are highest.
With both hydronic underfloor heating and electric underfloor heating systems, the room and/or floor temperature can be controlled via room thermostats. These ensure a superb level of space comfort while avoiding rooms being heated when this is not needed.
Electric Heating by Danfoss is energy efficient and environmentally friendly. It's a flexible solution for new build and renovation that can be used for wet and dry installation. Quick responding heating systems are easy to control. They enable you great comfort and convenience whilst ensuring user friendly solutions with lasting effect and highest quality standards.
