Description
Technical field
This utility model belongs to fresh air handining unit field, refers more particularly to a kind of double low-temperature receiver fresh air handining unit.
Background technology
Humiture independent adjusting air conditioner system, as the term suggests, this system is temperature and humidity independently to be entered
Row controls.In actual applications, humidity typically can be undertaken by a certain amount of new wind, and i.e. new wind needs to protect
Demonstrate,prove certain mass dryness fraction, undertake the humidity load of indoor, indoor normal humidity level can be maintained.General feelings
Under condition, outdoor new wind dustiness and water capacity are the biggest, cause being processed to suitable state needs
The biggest energy expenditure, so the fresh air proportion of air-conditioning is the most not too large, typically to meet personnel's
Health or technological requirement, say, that in the case of indoor humidity load is certain, if the wind of new wind
Measure less it is necessary to wind of looking for novelty has higher mass dryness fraction.
Current way realizes typically by double cold source air conditioning groups.So-called double low-temperature receiver, it is simply that have two
The low-temperature receiver of different evaporating temperatures, is also dual temperature.As in figure 2 it is shown, new wind is entered air-supply by new wind air inlet 2
Storehouse 15, after air filter 3, first passes through pyrometric scale cooler 4 and carries out cooling and dehumidifying, then through low temperature
Vaporizer 5 carries out degree of depth dehumidifying, makes the water capacity in air reach to meet the requirement of humidity load, by pressure fan
9 send into indoor through air outlet 8, and indoor return air is entered air draft storehouse 16 by indoor return air mouth 7, through condenser
12 cool down, meanwhile, the condensation heat that kind of refrigeration cycle produces, indoor air draft passed through by exhaust blower 14
Outdoor exhaust outlet 13 heat exchange is taken away, and dispels the heat in outside atmosphere.
This air-treatment measure exists following the most not enough:
Firstly, because whole dehumidification process be surface cooling cooling down dehumidifying, new wind through dehumidifying after, its
Dry-bulb temperature can be the lowest, and relative humidity, close to 100%, can make ajutage or air outlet 8 produce low temperature and coagulate
Dew phenomenon, causes and damages the hidden danger of installations and facilities in around ajutage and room.
Secondly, the temperature that air draft enters condenser 12 is higher, is typically not less than 26 DEG C, due to cold-producing medium
The restriction of condensation temperature, the heat dissipation capacity of condenser 12 has certain limitation, causes the cryogenic vaporizer of air-supply side
The dehumidifying effect of 5 also has certain restriction, does not reaches desired dehumidifying effect, thus air-supply can be caused dry
Degree deficiency, humidity over limit in room.
Again, the inlet temperature that condenser 12 is higher, it is unfavorable for the Energy Efficiency Ratio of refrigeration system, is unfavorable for energy-conservation.
