Heating and/or cooling power

Input

 BS

§ Unlimited it is assumed the generator has an unlimited power

§ Custom Value the maximum power produced by the generator should be specified. If the power required is higher that this delivered power, the design temperature may not be reached. In this case one should increase the power or use a secondary generator.

Power

[W, W / m² floor area] BS
This is the maximum thermal power of the emissive device, measured in kilowatts. If the specified power is unlimited, no excess hours develop based on the power of the emissive device. If excess hours do occur, another part must be limited. The thermal power may be specified for daytime operation and night time operation depending on the type of emissive device.

Convection factor

[Factor] BS
This is the convective part of the tactile power; the remainder is radiant heat. This convection factor only applies to ‘radiator’ emissive devices.

Specifications

 BS
If the emissive device has limited thermal power; the temperature specifications can be indicated:

      Default, for which the supply-, return-, and ambient temperatures are set at default values, irrespective of whether a heating, cooling, or heating and cooling device is concerned.

      Custom values, for which the supply-, return-, and ambient temperatures are specified by the user.

Supply

 Standard 90.0 °C for heating and 6.0 °C for cooling BS
This is the temperature of the supply water for the heated room. This temperature is dimensioning and hence it is not the heating curve used for the calculations. The water flow is determined based on the supply- and return temperature.

Return

 Standard 70 °C for heating and 12.0 ° C for cooling BS
This is the temperature of the water which returns from the heated room. This temperature is dimensioning and hence it is not the heating curve used for the calculations. The water flow is determined based on the supply- and return temperature

Environment

 Standard 20 °C for heating and 20 °C for cooling BS
This is the average ambient temperature of the surroundings of the generator.
