HEAT RECOVERY

General description

Heat recovery modules have following interests:
• In winter season and heating mode, the heat in the extract air is exchanged with the fresh air;
• Conversely, in summer season and cooling mode, the heat of the fresh air is transferred to the extract air.
There are 2 types of heat recovery modules integrated in the unit (as option):
- Recovery of the heat from the extracted air through a Rotary Wheel.
- Thermodynamic heat recovery module (TRMO), included in the machine. Its main interests are:
• A variable fresh air rate from 25 to 100%,
• A high COP in winter when pre-heating the fresh air due to a favorable evaporating temperature, especially with high air flow
rate;
• A high EER in summer when pre-cooling the fresh air due to a favorable condensing temperature, especially with high air flow
rate.
For those reasons, TRMO will be more suitable than Rotary Wheel in areas where the difference between indoor temperature and
outdoor temperature is low. For example, in Mediterranean areas, where winter temperatures are not very cold or summer
temperatures are not very high.
Rotary Wheel and TRMO will be delivered totally assembled in the unit (as option). All wire connections are factory made.
