22. HRV

22.1 Product introduction

Development background:
Under the background of energy getting more and more shortage and the use's request for the life quality getting
more and more high, we develop the heat reclaimed ventilation system to meet the needs.
Comparison between the HRV and the old sensible heat exchanger:
HRV is the changeover of sensible heat exchange and latent heat exchange, thus it can avoid the large number
of condensate water being caused when the unit operates in the condition of great humidity, furthermore the
condensate water needs the special drainage device, also the water always leaks to cause the unnecessary
economic loss.
So Haier HRV always is used at the coastal area to reduce the indoor humidity and gives the user a much more
comfortable space.
Advantage of using air conditioner with HRV comparing to using air conditioner individually:
a. The modern people seldom go out for the fresh air because of the busy work, and oppositely we always stay in
the airtight office with the unhealthy air. More and more we rely on the air conditioner, less and less we can adapt
the surroundings. After installing the HRV system, we can breathe the fresh air directly from outside, and make
us more healthier.
b. HRV needs not run for a long time such as the air conditioner. You can set ON or OFF in time to adjust the indoor
air quality.
