With continued reference to Fig. 1, in a kind of possible embodiment, double-cold source fresh air handling unit of the invention can be divided into summer
Pattern and winter mode, and the heat recovery system of the present invention is only opened in summer mode.
The summer mode workflow of double-cold source fresh air handling unit can be：
Fresh air unit 1：Fresh air is entered by the first air inlet 171, by the first roughing efficiency air filter 141 just imitated
Filter, filter out dust larger in fresh air → by medium effeciency filter 142 carry out medium air filtration, filter out tiny in fresh air
Grain, guarantee fresh air cleanliness factor → pass through first heat exchanger 131, completes heat recovery → warp of the precooling of fresh air, i.e. fresh air
High temperature surface cooler 11 (interior logical cold water) is crossed, the first cooling of fresh air → pass through evaporator 122 is completed, completes the depth cooling of fresh air
With dehumidifying → pass through second heat exchanger 132, the pre- heating of fresh air is completed, that is, reclaims the recycling of heat → by the first condensation
Device 123, heating up again for fresh air is completed, fresh air is reached the blower fan 16 of design temperature → first and go out the fresh air after processing by first
Interior is sent into air port 172.
Condense rejection units 2：Room air is entered by the second air inlet 241, is carried out just by the second roughing efficiency air filter 22
Filtering, filter out larger dust inside air → by evaporative condenser 124 and carry out heat exchange, absorb low temperature cold source system
The waste heat of system, make evaporative condenser cooling → at the same time, first recovery branch road 212 and second reclaim branch road 213 reclaims
Condensed water caused by high temperature surface cooler 11 and evaporator 122, spray equipment 215 is transported to by condensated water recovering pump 214, to steam
Hairdo condenser 124 carries out the blower fan 23 of spraying cooling → second and drains into the room air after processing by the second air outlet 242
It is outdoor.
The winter mode workflow of double-cold source fresh air handling unit can be：
Fresh air unit 1：Fresh air is entered by the first air inlet 171, and just mistake is carried out by the first roughing efficiency air filter 141
Filter, larger dust inside air → pass through high temperature surface cooler 11 (interior logical hot water) is filtered out, completes heating → process of fresh air
Humidification device 15, fresh air is carried out humidifying the → the first blower fan 16 fresh air after processing is sent into interior by the first air outlet 172.
Condense rejection units 2：Room air is entered by the second air inlet 241, is carried out by the second roughing efficiency air filter 22
Prefiltration, filter out the blower fan 23 of larger dust inside air → second and the room air after processing is passed through into the second air outlet
242 drain into outdoor, complete ventilation.
It should be noted that because winter does not have a heat cancellation problem, therefore winter mode is without needing to open heat recovery
System carries out heat recovery, and the heat exchange of generally high temperature surface cooler 11 and fresh air can meet the temperature requirement in winter, because
This is without unlatching low temperature cold source system.
