MRV indoor Ventilation

Heat Recovery Ventilation System (HRV) Solutions

• • Fresh air is introduced, in order to create a more comfortable indoor air environment. The Haier fresh air duct system can heat or cool the fresh outdoor air to close to indoor temperature and direct fresh air into the room. In spring and autumn, fresh air can be filtered without passing through the indoor unit, directly into the room to save energy. Using the environmentally friendly refrigerant R410A, DC inverter conversion technology is more efficient, more energy-saving.
  • The fresh air duct can be combined with the indoor indoor units of the MRV system to achieve unified management. Using a high-efficiency brushless DC fan motor, the rotation speed can be flexibly adjusted according to the actual static pressure to ensure stable air flow, greatly reducing the noise when operating.
  • The built-in float switch can monitor the condition of condensate in the catchment tray in real-time to avoid accidents, water leakage, and other potential hazards caused by poor drainage.

Characteristics of HRV systems

• • Design Standard: Meet the requirements of CE, ROSH and REACH, safer.
  • Super comfortable: Brushless DC motor, lower noise.
  • Easy maintenance: Hydrophilic material is added to the functional membrane used by the pellet, and its surface friction coefficient is improved; smaller dust particles will not stick to the membrane surface, no need to clean frequently, if cleaning is needed, just wash with tap water, dry and reuse (can be washed repeatedly). The heat exchanger core and filter are detachable from the structure design, which is more convenient for maintenance.
  • High efficiency: The heat exchanger core is made of graphene material, the effective air exchange rate is up to 95%, and energy saving thanks to efficient heat recovery technology. This device has a bypass function (the return air can be discharged directly from the outdoors through the bypass without passing through the heat exchanger), which effectively extends the service life of the heat exchanger. We recommend that you turn on the bypass function in spring or autumn.

Easy Control: Indoor unit linkage function, which can be connected to indoor units, according to the operation of the indoor units automatically controls the interlock to turn on/off the heat recovery ventilation (HRV) system.
