Heat exchanger COMFOFOND-L Q TR

The Zehnder ComfoFond-L Q brine-earth heat exchanger has been developed for use in conjunction with the Zehnder ComfoAir Q350/450/600 comfort ventilation units. It combines the highest comfort with very high efficiency in a compact installation. In winter, when the outdoor temperatures are low, it pre-heats the outdoor air to prevent freezing. This ensures optimum operation of the ComfoAir Q ventilation unit, even at outdoor temperatures below freezing. In summer, the ComfoFond-L Q sub-soil heat exchanger lowers the temperature of the outdoor air, and helps to support a conventional air-conditioning system. Energy saving due to use of renewable energy from the ground Maximum comfort due to pre-heating of outdoor air in winter using geothermal energy and temperature control of outdoor air in summer and winter for a comfortable indoor climate Compact, quick installation directly adjacent to the ventilation unit Simple and sustainable use of geothermal energy with a low power consumption Brine pump with energy efficiency class A Balanced ventilation even with low outside temperatures ■ Brine pump energy efficiency A rated ■ Safety valve: 3 bar ■ Automatic air vent ■ Filling and flushing system ■ Expansion vessel: 2 litres ■ Manometer: 0 to 10 bar ■ Connection pipe of pump and temperature sensor ■ DN 20 external thread connections for the brine pipes Zehnder ComfoFond-L Q brine-earth heat exchanger suitable for ComfoAir Q350/450/600 comfort ventilation units. In winter, the ComfoFond-L Q preheats the outdoor air before it enters the ventilation unit; in summer, it cools and dehumidifies the outdoor air.
