Background technology
At present, tobacco business sheet nicotinic alcohol warehouse, southern summer high temperature high humidity area, the cigarette finished product warehouse air-conditioning systems that adopt three kinds of forms: the 1. central air-conditioning of assembled air-conditioner unit more.This air-conditioning system adopts the central refrigerating station that 7 ℃ of chilled water coolings are provided, and the boiler room provides Steam Heating, though humiture can both be well controlled, has the energy waste phenomenon that operating cost is high, big, the cold and hot amount of conveying energy consumption is cancelled out each other; 2. thermostatic and humidistatic air conditioning unit group.This air-conditioning unit is different with the central air-conditioning of assembled air-conditioner unit is to adopt electrical heating to regulate the leaving air temp of electric refrigeration system, so still there is the cancel out each other problem of the energy dissipation that brings of electricity refrigeration and electrically heated cold and hot amount; 3. traditional air-cooled temperature adjusting and dehumidifying unit.This type unit not only moisture removal greater than the air-conditioning unit; And condensation heat capable of using thermal center again can; Use flexibly; Adopt the water-cooled temperature adjusting and dehumidifying machine set system of cooling water circulation cooling (needing to increase configurations such as cooling tower, water pump, pipeline, valve) simple more, management is convenient, thereby uses more in actual use.
The air-cooled temperature adjusting and dehumidifying unit operation principle of tradition is as shown in Figure 1.Form by tactic evaporimeter 1, heating power expansion valve 2, liquid reservoir 3, compressor 4, outdoor air-cooled condenser 5, outdoor condensation exhaust machine 6, indoor air-cooled condenser 8, indoor blower 7.Refrigerant system design has two series connection air-cooled condensers 5 and 8, and indoor air-cooled condenser 8 is positioned at after the indoor machine evaporation 1, and outdoor air-cooled condenser 5 is positioned at off-premises station.
The air-cooled temperature adjusting and dehumidifying unit course of work of tradition is following: the refrigerant gas of discharging through compressor 4 at first passes through outdoor air-cooled condenser 5 heat exchange; Cold-producing medium after the heat exchange continues to get into evaporimeter 1 through liquid reservoir 3, heating power expansion valve 2 throttlings cooling back successively after the heat exchange condensation through indoor air-cooled condenser 8 again; Absorb the room air heat; Evaporation becomes low pressure refrigerant vapor, is compressed machine 4 again and sucks compression, accomplishes a kind of refrigeration cycle.
The operation principle of the air-cooled temperature adjusting and dehumidifying unit temperature adjusting and dehumidifying of tradition is:
Indoor humid air is through evaporimeter 1 cooling, and temperature is reduced to below the dew-point temperature, and the water in air segregation junction is separated out, and the air water capacity is reduced; Pass through again after the indoor air-cooled condenser 8; Wet heating such as humid air quilt, temperature rising back is sent into indoor through indoor blower 7, indoor air temperature rising, relative humidity are reduced; This moment, outdoor condensation exhaust machine 6 was out of service, and this is the dehumidifying operation principle that heats up; When opening or the air quantity of the outdoor condensation exhaust machine 6 of variable frequency adjustment through being interrupted; The heat exchange ratio of outdoor air-cooled condenser 5 is increased; The heat exchange ratio of indoor air-cooled condenser 8 reduces; Make to reduce through the wet heats that add such as humid air after the indoor air-cooled condenser 8 that temperature raises less, this is the temperature adjusting and dehumidifying operation principle; Air quantity when all one's effort opening chamber condensed exterior exhaust blower 6; Make the heat exchange ratio of outdoor air-cooled condenser 5 reach maximum; The heat exchange ratio of indoor air-cooled condenser 8 is reduced to zero, is zero through the wet heats that add such as humid air after the indoor air-cooled condenser 8 then, and temperature can not raise; Be in the dew point ventilation state, this is the cool-down dehumidification operation principle.
