Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Referring to Fig. 1, present embodiment comprises the breeze fan 1 that is installed on the airduct left end, the airduct connecting reducing pipe 1 after the breeze fan 1, and the left side diameter of reducer pipe 1 is less than right side diameter, in reducer pipe one 2 right-hand member centers current equalizer 3 is installed; Dehumidifying surface cooler 1 and dehumidifying surface cooler 26 are installed in reducer pipe 1 airduct afterwards side by side, thereafter, the watertight shutter 7 of installing successively in the airduct, reheater 8 are by processing wind air channel 12 and reducer pipe 29 UNICOMs, the left side diameter of reducer pipe 29 is larger than right side diameter, volume damper 10 is installed after the reducer pipe 29, forms by ajutage 11 at last and process the wind passage.As seen from the figure, be provided with condense water disk 4 under dehumidifying surface cooler 1, dehumidifying surface cooler 26 and watertight shutter 7, condense water disk 4 and condensate pipe 23 UNICOMs are convenient in time discharge the condensed water that produces in the air dewetting process.Dehumidifying surface cooler 1 and compressor 1, air-cooled condenser 14, heating power expansion valve 1 are connected successively by refrigerant tubing, form the air-supply loop dehumidification, carry out the dehumidification by condensation processing by one 5 pairs of air of dehumidifying surface cooler; In the left end airduct of air-cooled condenser 14 condensation exhaust blower fan 22 is installed, the right-hand member of air-cooled condenser 14 is connected with condensating wind air channel 13, forms the condensating wind passage.Dehumidifying surface cooler 26 is connected by refrigerant tubing 15 successively with compressor 2 19, reheater 8, heating power expansion valve 2 17, form air-supply dehumidifying, reheat loop, carrying out dehumidification by condensation by 26 pairs of air of dehumidifying surface cooler processes, utilize the condensation heat of refrigeration system that the air after dehumidifying is carried out again heat treatment by reheater 8, improve wind pushing temperature, reduce air-supply relative humidity, reduce simultaneously again thermal energy consumption.
Among Fig. 1, control cabinet 21 links to each other with breeze fan 1, condensation exhaust blower fan 22, compressor 1, compressor 2 19 by control circuit 20, and these equipment are played the control and protection effect, and every equipment is independent on off control all.Control cabinet 21, breeze fan 1, condensation exhaust blower fan 22, compressor 1, compressor 2 19 all have explosion-proof, flame proof function.In order to save cold, reduce pipeline condensed water all around and occur, process wind air channel 12 and refrigerant tubing 15 external surfaces insulation layer is housed.
The utility model is the method that adopts dehumidification by condensation, removes processed airborne steam.Moist underground air draws lower taking out of breeze fan, enter the dehumidifying surface cooler through reducer pipe one, current equalizer.The effect of current equalizer is when making distinguished and admirable process dehumidifying surface cooler, and is more even, thereby effect on moisture extraction is better.The dehumidifying surface cooler is comprised of dehumidifying surface cooler one, dehumidifying surface cooler two, is relation in parallel between dehumidifying surface cooler one and the dehumidifying surface cooler two.When processed air flow through the dehumidifying surface cooler, under the effect of low-temperature refrigerant, airborne steam can condense at the external surface of dehumidifying surface cooler, thereby separates from air in the dehumidifying surface cooler.Watertight shutter is equipped with in back at the dehumidifying surface cooler, and its Main Function is to avoid distinguished and admirable condensate water is taken away.Below dehumidifying surface cooler and watertight shutter condense water disk is installed, the water droplet of separating from air falls into condense water disk, discharges outside the unit by the condensate pipe that is installed on the condense water disk again.
Descend through the air humidity content after the dehumidifying surface cooler, simultaneous temperature is also lower, relative humidity is also higher, in order to improve wind pushing temperature and to reduce air-supply relative humidity, flow through reheater through the air after the dehumidifying surface cooler, under the effect of the high temperature refrigerant in reheater, air themperature raises, relative humidity reduces.Through the air after the heat again, after reducer pipe two, volume damper, ajutage, send in the down-hole chamber that needs dehumidifying, to keep chamber inner drying, comfortable air ambient.Volume damper can as required, be regulated the air output of chamber.
Compressor one, air-cooled condenser, heating power expansion valve one, dehumidifying surface cooler one join end to end by refrigerant tubing, form the air-supply loop dehumidification.After heating power expansion valve one reducing pressure by regulating flow, cold-producing medium becomes low temperature gas-liquid two-phase cold-producing medium, this low-temperature refrigerant enters after the dehumidifying surface cooler one, and absorption is flow through the airborne heat of dehumidifying surface cooler and vaporized, and becomes refrigerant gas by refrigerant liquid.After the air release heat, temperature reduces, and water capacity descends.Refrigerant vapour after the vaporization is sucked back by compressor one, and is again compressed, becomes high temperature and high pressure gas.The exhaust of compressor one enters air-cooled condenser.Draw lower taking out of condensation exhaust blower fan, surrounding air flows through air-cooled condenser, high-temperature high-pressure refrigerant steam cools off in it to flowing through, the refrigerant vapour heat release of HTHP is condensed into the liquid of HTHP, after heating power expansion valve one reducing pressure by regulating flow, recover again refrigerating capacity, so move in circles, ceaselessly dehumidify to processing air.Absorbed condensation of refrigerant heat high temperature condensation exhaust afterwards, under the effect of condensation exhaust blower fan, be expelled back among the atmosphere again.
Compressor two, reheater, heating power expansion valve two, dehumidifying surface cooler two join end to end by refrigerant tubing, form air-supply dehumidifying, reheat loop.Different from above-mentioned simple refrigerated dehumidification loop, in air-supply dehumidifying, reheat loop, high-temperature high-pressure refrigerant steam from compressor two is not sent to air-cooled condenser, but be sent to reheater, to heating through the processing air after the dehumidifying surface cooler cooling and dehumidifying, to improve the wind pushing temperature of processing air, reduce its relative humidity.Utilize the condensation heat in the refrigerated dehumidification process that again heat is carried out in air-supply, can save again thermal energy consumption, can reduce the condensation exhaust fan energy consumption simultaneously.Release heat is given and is processed after the air, the high-temperature high-pressure refrigerant steam is condensed into high temperature high pressure liquid in reheater, this liquid refrigerant is through after heating power expansion valve two reducing pressure by regulating flows, become low-temperature refrigerant, entering two pairs of surface coolers of dehumidifying processes after air dehumidifies, become low-temp low-pressure gas, again sucked back by compressor two.So iterative cycles is constantly realized the dehumidifying of processing air and hot again.
Above content described in the present embodiment only is to the explanation of the utility model structure example; the various modifications that the described specific embodiments of the utility model is made, replenish; perhaps adopt the replacement of similar technical characterictic; only otherwise depart from technical conceive of the present utility model; perhaps do not surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
