150-350m3/h indoor/buildings climate control heat energy recovery ventilation vents for greenhouse

Product Description


Selection and Model Description:

Selection instructions:

Product Feature:

The product air volume range is from 200-500 m3/h, suitable for villas, residential, conference room, office, and others with high purification requirements;


A large primary filter that has large dust capacity, and long service life.


The beginning of efficiency filter and high-efficiency filter that can effectively remove PM2.5 particles from the outdoor air.


The filters adopt pull-type installation structure, and easy to maintain.


Unit with energy recovery, double bidirectional air ventilation, and air purification filter combination ensure the delivery of air is fresh and clean.


The air volume is divided into high, medium and low grades that can be adjusted as needed.

Optioning three-speed control switch or LCD smart controller.


The heat exchanger performance distinction: Q is the Plate Heat Exchanger; X is the Sensible Heat Recovery.   


Installation form distinction for energy recovery fresh-air exchanger: D is ceiling type, L is floor model, WG is external hanging, and NG is internal hanging.


Operation mode, the blank is single speed, and the T is multispeed.


Function Distinction: S series, H series, F series, and C series have cold and heat source; Moreover, the P series has the by-pass function. For example, XHBQ-D3TL or XHBQ-D3TM is ceiling type of fresh air exchanger, and L is hexagon plate heat exchanger, M is rectangle plate heat exchanger. Furthermore, the air volume is 300m3/h and the air volume can be adjusted by grades. 


LCD Smart Controller:

It has a touch sensitive key controller, automatic switch time setting, air supply, and air exhaust operation instruction, and three-speed adjustment. Moreover, the screen shows a clock, indoor temperature, and by-pass instructions. Furthermore, when the product running for a long period, the screen will remind the owner to clean or change a filter. More importantly, it can connect to the Internet.

According to the characteristics of the structure of the building, different types of fresh air exchanger are selected;

According to the use of the rooms, area, and the number of internal personnel to determine the appropriate amount of fresh air;

According to the determined amount of fresh air, select the specifications and quantity of the equipment.



Calculation Example:

An office dimension is S=60 m2, net height is h=3m, personnel is n=10 people, Calculate the amount of fresh air per person, and taking each people needs of the fresh air volume is q=50m3/h, ultimately the fresh air volume is Q1=n.q=10*50=500m3/h.

However, according to the fresh air number of times changes, the result of the frequency of fresh air is p=3 times/h. Finally, the fresh air volume is Q2=p.s.h=3*60*3=540m3/h.


As a device selection parameter is Q2>Q1, therefore the Q2 is the best one.
