Abstract
The utility model discloses a blowing damp-eliminating device for underground equipment, which comprises an air intake blower, an exhaustion blower, a refrigerant radiator, a refrigerant heat exchanger and a refrigerant compressor. The utility model is characterized in that the blowing damp-eliminating device comprises a three flow heat exchanger, which is divided into a heat exchange cavity and a damp-eliminating cavity. An air intake cooling coil and an air intake heating coil are arranged in the heat exchange cavity. The refrigerant heat exchanger is arranged in the damp-eliminating cavity. A water collecting spout is arranged at the bottom of the damp-eliminating cavity. The intake of the cooling coil is connected with the air intake blower, and the outlet leads into the damp-eliminating cavity. The air intake heating coil is connected with the bottom of the damp-eliminating cavity, and the outlet of the air intake heating coil is an air outlet. The utility model adopts the damp-eliminating method of low temperature condensation, removes excessive moisture in air by condensing, and achieves the damp-eliminating purpose. The utility model carries out twice heat exchange before and after damp-eliminating by using exhaustion and air intake, which reduces the power consumption of air conditioning refrigeration.
Description
A kind of underground installation air-supply dehydrating unit, it belongs to building environment conditioning equipment, can be used for the ventilation of various buildings, is specially adapted to as the ventilation of humidity such as underpass, basement than overall situation.
At some heavy constructions such as auditorium, gymnasium institute or the various halls etc., all need to carry out the artificial draft temperature adjustment.And for the hypogee facility, as basement, subway passage etc., also need to keep as oxygen concentration, reduce the concentration of various pernicious gases and dehumidifying etc.In summer, because extraneous relative humidity height, temperature is also high, just makes airborne absolute humidity very big.And, will make relative humidity reach 100% to building air-supply and when reducing temperature, can not satisfy the requirement of air conditioner ventilation.Particularly in the hypogee, also has the requirement of hydrofuge, to discharge underground moisture.And present existing air-conditioning blowing device generally all can not dehumidify.For demanding Architectural Equipment, the also employing used drier absorption moisture content more.This method cost height needs regularly to change the regeneration drier, has increased operation, maintenance workload.
The purpose of this utility model is a kind of underground installation ventilation drying device of invention, and it does not use drier etc., can move continuously, and the humidity of sending into air is reduced.
Structure of the present utility model as shown in Figure 1, it has air intake blower fan 1, air draft blower fan 2, refrigeration and heat radiator 3, refrigeration heat converter 4, refrigeration compressor 5, refrigeration and heat radiator 3 is loaded on outside the building, it is characterized in that: three stream heat exchangers 6 are arranged, three stream heat exchangers 6 are divided into heat exchanging chamber 7 and dehumidifying chamber 8, air intake cooling coil 9 and air intake heat(ing) coil 10 are arranged in heat exchanging chamber 7, refrigeration heat converter 4 is contained in the dehumidifying chamber 8, in dehumidifying 8 bottoms, chamber the discharge outlet of catchmenting 11 is arranged, air intake blower fan 1 links to each other with the inlet of cooling coil 9, the outlet of cooling coil 9 feeds in the dehumidifying chamber 8, dehumidifying 8 bottoms, chamber link to each other with air intake heat(ing) coil 10, and the outlet of air intake heat(ing) coil 10 is an air outlet, and the delivery outlet of air draft blower fan 2 communicates with the position of heat exchanging chamber 7 near dehumidifying chamber 8 ends, the other end and the building of heat exchanging chamber 7 are interlinked to the outside, and are exhaust outlet.
Accompanying drawing 1 is a structural representation of the present utility model.
Operation principle of the present utility model is as follows:
Extraneous hot and humid air is carried by air intake blower fan 1, enters into the air intake cooling coil 9 of three stream heat exchangers, 6 heat exchanging chambers 7.In heat exchanging chamber 7, carry out heat exchange with building internal haze air that extract out by air draft blower fan 2, hypoxemia and high pernicious gas content.Because air themperature is the normal temperature of setting substantially in the building, therefore can absorb the air intake heat, makes it to drop near normal temperature in the building.Air intake air after the cooling enters in the dehumidifying chamber 8.Refrigeration heat converter 4 is arranged in dehumidifying in the chamber 8,, be further cooled when cooling to after air intake air near design temperature enters.Because after the cooling of air intake air, airborne moisture is in hypersaturated state, in dehumidifying chamber 8, condense into water, flow to the bottom, discharged from discharge outlet 11.The relative humidity that is in low temperature is 100% air intake air enters into heat exchanging chamber 7 from dehumidifying 8 bottoms, chamber air intake heat(ing) coil 10.In air intake heat(ing) coil 10, carry out heat exchange, absorb the heat (air draft absorbs heat from air intake cooling coil 9) of air draft with air draft.Make temperature recovery, when reaching the control design temperature, send in the building, because temperature recovery reduces relative humidity.Satisfied the requirement of ventilation air intake.
The utility model adopts the method for cryogenic temperature condensation dehumidifying, and the air intake air themperature is reduced to below the required design temperature, makes it condensation and removes unnecessary moisture content, reaches the purpose of dehumidifying.Needed air intake humidity can be controlled by the difference of air intake design temperature and dehumidifying chamber condensation temperature.The temperature difference is big more, and the relative humidity that obtains is more little.Carry out heat exchange twice with the dehumidifying back before using the dehumidifying of air draft and air intake, make the consumption of air conditioner refrigerating energy seldom.And the utility model is a kind ofly to dehumidify continuously naturally, and the consumption of no drier does not have the management maintenance problem of runtime yet.
Refrigeration and heat radiator 3 in the utility model, refrigeration heat converter 4 and refrigeration compressor 5 can use the structure of common split-type air conditioner, can also directly use its repacking, and the utility model does not have specific (special) requirements.
Air intake cooling coil 9 best level in three stream heat exchangers, 6 heat exchanging chambers 7 of the present utility model are placed, and make conduit axis in a horizontal plane.When air intake humidity was high, some moisture content wherein just may condense in cooling coil 9, and such structure makes the moisture content that condenses be brought in the dehumidifying chamber 8 by the air intake air-flow easily and discharges.Air intake cooling coil 9 and air intake heat(ing) coil 10 can be arranged in parallel, and air exhaust passage is arranged between the two, and both are directly contacted, and connect with heat-transfer metal, directly carry out heat exchange.Air intake heat(ing) coil 10 can be shorter than air intake cooling coil 9.
Air intake blower fan 1 and air draft blower fan 2 that the utility model uses can use common centrifugal fan, also can use common axial fan, and the utility model does not have specific (special) requirements.
Refrigeration and heat radiator 3 in the utility model can be positioned over the outer exhaust outlet place of building, and the row's of use mouth is strengthened cooling effect to its cooling.
