ISPK Modular compact heat pumps nAssemblies with mixingbox with 2 motorised damper forImportant: In compact version, the connection of the mixing air renewal and free-cooling: box with its structural support is under the responsability of the installer. Assemblies with mixing box Models 90 to 360 (plan view) nFree-cooling management: M0110 MS111 MS116 Running the unit in free-cooling mode allows it to make best I I R I N use of outdoor air conditions when these are more favourable N R than the return air conditions. This allows the cooling capacity to be reduced. The percentage of outdoor air can vary MS411 R MS114 N between 0% and 100%. There are three options for free-cooling management: I I N R • Thermal, by comparing the temperatures. • Enthalpic, by comparing the enthalpies. Recommended in MS413 R MS314 N cases where a high moisture content in the air is foreseen. I I • Thermoenthalpic,by comparing the enthalpies and correcting for temperature. This is the optimum solution as it takes the variability of the climate into account.
