UNIT DESIGN AND OPERATING LOGIC
The unit operating logic is illustrated in Fig. 2. The warm stale air from indoors is supplied into the
unit where it undergoes fi ltration. The fi ltered air is directed into the heat exchangers and extracted
outdoors via the air duct system by the extract fan. The fresh cold air from outdoors is supplied
into the unit where it undergoes fi ltration. The fi ltered air is directed into the heat exchangers and
supplied into the premises by the supply fan. The heat exchangers ensure the heat energy exchange
between the warm stale air from indoors and the cold fresh air from outdoors without air stream
intermixing. Such design reduces heat energy losses and helps to minimize heating expenses in the
cold season.
The unit design and operation logic are given in Fig. 2. The basic unit equipment includes:
1.
Extract motor-impeller block.
2.
Supply motor-impeller block.
3. Cross-fl ow plate heat exchanger.
4.
G4 extract fi lter.
5.
G4 supply fi lter.
