FAQs

How enthalpy exchanger works? How enthalpy exchanger works?

By recovering and reusing the energy from the exhaust air, enthalpy exchangers effectively reduce the energy demand of the HVAC system, improve indoor air quality, and enhance overall energy efficiency in buildings.

Filter replacement Filter replacement

1、When the controller cartridge progress bar shows red, please replace the cartridge in time. 2、Open the middle gland plate of the exchange core in the direction as shown. 3、Take out the cartridge in the direction of the figure and replace it. 4、Put the replaced cartridge into the corresponding slot and cover the exchange core gland. 5、Open the cartridge setting page of the controller and press and hold the cartridge progress bar for 5 seconds to reset the cartridge balance, and the display shows 100% that the reset is successful. Note: Steps 1 and 5 are required for CLS4.0S LCD controller, if you purchase other controllers, please refer to the manual of the controller.

How many modes of Menred G3 ventilator can be set? How many modes of Menred G3 ventilator can be set?

Energy saving mode: The air volume of exhaust air and fresh air are equal. Default wind speed is low speed. Haze removal mode: The fresh air is high speed, the exhaust air is low speed, and the wind speed shows high speed. Sleep mode: Both fresh air and exhaust air are low speed, wind speed shows low speed. Auto mode: Automatically adjust the airflow level according to the indoor CO2 and PM2.5 concentration. User can set the corresponding value in the setting page. For example, when PM2.5 is set to High > 100 > Medium > 35 > Low and C02 is set to High > 1500 > Medium > 700 > Low, when the air quality sensor detects PM2.4 > 100 and CO2 is between 700 and 1500, the wind speed is high.

what is an enthalpy exchanger what is an enthalpy exchanger

Enthalpy exchangers are particularly useful in climates where there are significant temperature and humidity differences between the indoor and outdoor environments. Apart from transferring sensible heat (temperature), they also transfer latent heat (moisture) between the airstreams, providing the benefits of both heat and moisture recovery.

Why do our home need ERV ventilation? Why do our home need ERV ventilation?

When two people sleep for seven hours, their sweating and breathing produce approximately 7.5 to 8 decilitres of moisture and about 150 to 200 litres of carbon dioxide. They also release some 250 to 300 watts of heat to indoor air. If the moisture content of indoor air rises too high, the moisture condensates in the windows or in the structures of the cold external wall. Structures that have become moist are breeding grounds for microbes and mould fungi, which will before long cause damage to the structures. Almost all fungal mycelia grow at a relative moisture of more than 80% and in normal room temperature. Efficient ventilation removes the carbon dioxide and moisture load as well as smells, taking them out of the house.

When should I replace the filter? When should I replace the filter?

The default setting of filter life is 6 months(which can be reset in WeChat). After using for 6 months, the filter icon will flash to remind the user to replace the filters. After replacing the filter, long press the filter button for 5 seconds to reset the time.

How to choose the suitable type of ventilator? How to choose the suitable type of ventilator?

If the area of a computer room is 60 sq meter(S=60), the net height is 3 meters(H=3), and there are 10 persons(N=10) in it. If it is calculated according to “Personal fresh air consumption”, and assume that:Q=70, the result is Q1=N*Q=10*70=700m³/h If it is calculated according to “Air change per hour”, and assume that: P=5, the result is Q2=P*S*H=5*60*3=900m³/h Since Q2＞Q1，Q2 is better for selecting the unit. As to special industry such as hospitals(surgery and the special nursing rooms), labs, workshops, airflow required should be determined in conformity with regulations concerned.
