Calculation formula:
The temp. of the fresh air after heatexchange by HRB
= (indoor temp.-outdoor temp.) x HRB efficiency
+ outdoor temp.
For example: (20°C-0°C) x 70% + 0°C = 14°C
32°C
Outdoor fresh air
The HRB heat exchanger can introduce the fresh air
into a close area, which is energy saving, reducing its
energy consumption by more than 60%. There are 6
units for option, including 300m3/h, 500m3/h, 800m3/h,
1000m3/h,1500m3/h, 2000m3/h.

Indoor air
The HRB heat exchanger has the function of air
exchange,when it brings the fresh air into the indoor,
it also discharges the dirty air outside, which can save
a lot of money.
Cooling

Calculation formula:
The temp. of the fresh air after heatexchange by HRB
= outdoor temp. - (indoor temp.-outdoor temp.)
x HRB efficiency
For example: 32°C - (32°C-26°C) x 70% = 27.8°C
Comfortable Manual Environment
Beside primary air filter, HRB provides active carbon
filter,bactericidal lamp and humidifier, which can filtrate the dust,SO2, O3, NH3, as well as benzene to improve the indoor airquality.
SO2,O3,NH3,benzene,eto.
Flexible Control Combination
Central control
HRB can be separate control or centralized control,
the out-line is similare to the air conditioner and is easy
to install and maintain. It can meet the requirement of
the customer: healthy and energy saving.
High Efficiency
The max. Temp. recovery efficiency of HRB is 79%, the max. Enthalpy
exchange efficiency is 66%, which reduce the fresh air load of the air
conditioner and save a lot of money.
High heat exchange efficiency of 79%.
Industry-leading moisture penetrability, strong flameretardance
Height of body reduces 50%.
No fresh air and return air combination, more reliable.
