Description
Technical field
The present invention relates to airhandling equipments can more particularly to a kind of vaporation-type solution heat-recycling air treatment device
Avoid fresh air and return air cross contamination.
Background technology
With the development of society, while ventilation, how it is more energy efficient be target that fresh air industry is pursued always,
Traditional fresh air recuperation of heat at present mainly using rotary-type recuperation of heat and plate-fin recuperation of heat and glycol heat recovery system,
In, the operation principle of rotary-type recuperation of heat is：Runner is the medium for transmitting energy, and air draft is by one of semicircle by energy
It is temporarily stored within wherein, when this semicircle rotates to fresh air side, the energy in this is taken away and is sent to interior by reverse fresh air, in this way
Fresh air and air draft by it is this it is reverse it is alternate in a manner of by runner, reach energy regenerating.The operation principle of plate-fin is：By aluminium foil
Or special paper is assembled into the ventilation duct that section is triangle, U-shaped, N shapes, new air draft is passed through from respective air duct, to transmit
Energy.The operation principle of glycol heat recovery system is：Using the cycle of ethylene glycol, the ethylene glycol in the coil pipe of return airway absorbs
Heat or cold in return air, are recycled in the coil pipe in fresh air duct, and the heat being absorbed into or cold are released to again
Fresh air is sent to interior.Three of the above recuperation of heat mode has certain limitation, rotary-type recuperation of heat to be suitable only for fixed air duct,
And plate-fin recuperation of heat is also designed just for small air quantity, the efficiency of glycol heat recovery system is relatively low, runner and board-like recuperation of heat
The fresh air return air that mode uses is alternately through can not avoid the cross contamination of fresh air return air.
Invention content
The purpose of the invention is to overcome prior art there are the shortcomings that, provide a kind of using ethylene glycol and water as passing
Medium is passed, it can be to avoid the vaporation-type solution heat-recycling air treatment device of fresh air return air cross contamination.
The technical solution of vaporation-type solution heat-recycling air treatment device of the present invention is：Including being equipped with fresh wind port and air outlet

Glycol circulation pump and air draft glycol heat recovery system coil pipe, air draft glycol heat recovery system coil pipe and fresh air ethylene glycol coil pipe between by
Ethylene glycol pipe dredges cycle.
The vaporation-type solution heat-recycling air treatment device of the present invention, the indoor return air cabinet and outdoor fresh air cabinet
Opposing seal, though it is integrally attached to, but each own individual cabinet, it can freely assemble, avoid indoor return air and outdoor fresh air
Between cross contamination.According to air force, fresh air first passes through water coil and cools down in advance（By 27 degree of water services of room temperature to water pond
In pipe, 31 degree are cooled in advance to 35 degree of fresh airs）Using being sent to interior after fresh air ethylene glycol coil pipe again deep temperature reduction.Interior is returned
The shower water that wind first passes through cascade wet film tentatively cools down to shower water, and shower water evaporation endothermic becomes low temperature, and condensed water is fallen
In bottom drip tray, it is transported in the water coil in outdoor fresh air cabinet to fresh air by water circulating pump when water level reaches a fixing limit
Pre- cooling processing, and return air is also cooled down simultaneously, is passing through air draft glycol heat recovery system coil pipe, air draft glycol heat recovery system disk
Ethylene glycol in pipe cools to low-temperature glycol, rear return air discharge, and low-temperature glycol is transported to fresh air second by glycol circulation pump
Triple recuperation of heat effects are realized to the fresh air deep temperature reduction to cool down in advance, so cycle in glycol coil pipe, for the first time, condensation water quantity is not
Tap water at normal temperature and fresh air when sufficient；For the second time, the fresh air and low-temperature glycol after pre- cooling；For the third time, in return air discharge process,
Deep temperature reduction of the water heat absorption to ethylene glycol is evaporated, to realize deep temperature reduction of the low-temperature glycol to fresh air.This programme utilizes second
Based on glycol, the medium supplemented by tap water transmits energy, will not cause other pollutions, efficient, energy consumption is also small.
The vaporation-type solution heat-recycling air treatment device of the present invention, the drip tray are equipped with dewatering outlet, water inlet
And overflow port.When not needing recuperation of heat, the water in drip tray is all discharged, water inlet is used to not arrive to limit when condensed water
When, for supplementing the pre- cooling for meeting fresh air in tap water at normal temperature to the water coil in outdoor fresh air cabinet；Overflow port is for working as
The excessive condensation dilutional hyponatremia of shower water water or water circulating pump go wrong when cannot make its whole system complete cycle, at this time water receiving
Disk can the spill-over due to cycle dilutional hyponatremia, therefore overflow port is under situation in this.The return air inlet and exhaust outlet is located at
The bottom sides of indoor return air cabinet and top, fresh wind port and air outlet are located at the bottom and top of outdoor fresh air cabinet,
Enter conducive to fresh air and return air is sent out.The water coil and fresh air ethylene glycol coil pipe is located at before fresh wind port and hangs down with fresh wind port
Directly, assembly is utilized.The indoor return air cabinet of plane where the size of the air draft glycol heat recovery system coil pipe is equal to this coil pipe
Internal diameter, be conducive to air draft cool down.The exhaust outlet of the indoor return air cabinet is equipped with exhaust blower, the outdoor fresh air cabinet
Air outlet is equipped with pressure fan, utilizes air draft and air-supply.It is equipped with bypass air duct below the exhaust blower, bypasses and is equipped with air-valve in air duct
With bypass air port, it is not necessarily to air draft when recuperation of heat for spring and autumn transition season, opens air-valve, return air enters bypass wind by return air inlet
Road is expelled directly out outdoor by bypassing air port by exhaust blower.
