Selection Table of AHU
1. Both supply fan and exhaust fan are built inside tobring in fresh air and exhaust out the stale indoor air as well, thus to keep indoor space in natural comfort.
2. Built-in heat exchanger (rotary heat exchanger or plate heat exchanger) transfers energy contained in the outgoing indoor air to the coming fresh air,thus fresh air is precooled or preheated.
3. Various functional sections such as filter section,cooling/heating section, humidifying section etc.can be combined together to meet different air treatment requirements.
Combination mode 1:
Wheel + Coarse filter (medium filter) + Cooling coil (heating coil)+ Humidification + Fan
Combination mode 2:
Plate heat exchanger + Coarse filter (medium filter) + Mixed air +Cooling coil (heating coil) + Fan
AHU functional Section -Heat Exchanger Section
1)Rotary heat exchanger (heat recovery wheel) is mainly used in building ventilation or in the air supply, discharge system of air conditioning equipment. The wheel transfers the energy (cold or heat) contained in exhaust air to the fresh air supplied to indoor.It’s a piece of important equipment and a key technology in the field of construction energy saving.
(1) Sensible heat exchanger is made of pure aluminum foils which is specially designed for air to air heat exchanger, high efficiency, washable and minimizing cross contamination. (2) Enthalpy heat exchanger is made of special E.R paper, the membrane fiber gap is very small which only allow moisture molecule goes through so laten heat recovered. This feature can avoid the harmful gas or odor from stale air mix up with fresh air. (3) No moving part inside, easy to maintain and no extra running costs. |
We offer different types of fans such as direct driven centrifugal fan, belt driven DIDW forward centrifugal fan, and belt driven DIDW backward centrifugal fan etc..
In order to ensure heat exchanging efficiency and cleanness, combination of G3 coarse filter and F5 medium filter is selected as standard configuration in HJK AHU.
