The heat recovery ventilator is a two-way flow ventilation system. Its unique synchronous suction and exhaust function enables the exhaust and intake to be carried out at the same time, forming an all-round circulating air convection. It can quickly discharge the exhaust air in the room after filtering, and replenish the filtered fresh air in time. When the rated air volume of air supply and exhaust is the same, its ventilation effect can reach more than twice that of ordinary ventilation fans.
The heat recovery ventilator hrv is equipped with a coarse filter, or a special filter such as activated carbon and negative ions to filter and adsorb toxic gases such as SO2, NH3, benzene, and formaldehyde. The imported H13 filter material is selected in the machine, which can not only prevent the intrusion of pollen and dust above 10 microns in the atmosphere, but also filter harmful microorganisms such as viruses, bacteria, mites and 50% of PM2.5, introduce the quality of fresh air to bring fresh and pure air to users.
The core component of the residential heat recovery ventilator is the heat exchanger, which can recover the heat from the exhausted air in room. In summer, the cold energy in the exhausted air is recovered, and the outdoor hot air is pre-cooled by heat exchanger and sent indoors, in winter, the heat of the exhausted air is recovered, and then the outdoor cold air is preheated and sent into the room, thereby reducing energy loss and reducing the energy consumption of underfloor heating or air conditioning for cooling and heating.
The heat recovery ventilator is a high-efficiency, energy-saving and environmentally friendly all-round ventilation system. It is widely installed and used in office buildings, hospitals, hotels, stations, airports, residences, villas, and entertainment venues. Due to the higher technical content, good ventilation effect and heat recovery function, the heat recovery ventilator price is also higher than general ventilation equipment.
Net zero building is a building with net zero energy consumption, meaning the total of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site or in the other definition by the renewable energy sources offsite, using technology such as solar power, wind power, heat pumps, indoor with high efficiency windows and insulation, in such kind of situation, Energy recovery ventilation will be more suitable. ERV system allows for partial transfer of heat and moisture from indoor exhaust air to the supply fresh outdoor air, it's more energy saving.
HRV only transfers the heat is a better option when home is too mosit in winter or summer(more than 60%), as it would get rid of extra mositure in exhaust air.
Heat recovery systems typically recover about 60-95% of heat in exhaust air and have significantly improved the energy efficiency of buildings. There are two products recommended as the best in the past year for their high performance and energy saving.
