Technical field
The utility model belongs to the air conditioner refrigerating technical field, relates to a kind of air conditioner ventilating system that is applicable to, is specifically related to a kind of subway station with the aeration-cooling unit of heat pipe heat reclamation type evaporative cooling.
Background technology
Statistics shows; The power consumption of the air conditioner ventilating system in the subway station accounts for 30%~60% of building total energy consumption; Wherein handle the required energy consumption of new wind and account for 20%~30% of air conditioner ventilating system energy consumption again, this shows that the energy that exhaust system is taken away in the air-conditioning system is considerable; Abundant " excavation " exhaust system energy reclaims in the subway ' s air-conditioning system, reaches energy-saving and cost-reducing requirement.
1. the air-air recuperation of heat product category of developing both at home and abroad is a lot, like board-like heat regenerator (heat recovery efficiency 40%~60%), rotary-type heat regenerator (heat recovery efficiency 70%~80%), heat pipe-type heat regenerator (heat recovery efficiency 60%~70%) etc.Wherein the application of plate-fin heat regenerator is wider, though this heat exchanger structure is compact, heat exchange efficiency is higher, because the heat exchanger runner is narrow, water quality is prone to fouling when hard, and difficulty is cleaned, and resistance is big, and energy consumption is big.
2. the air-conditioning form is directly cooled off in the single-stage evaporation of evaporative cooling system employing, receives many restrictions of conditions such as weather and region easily, the problems such as use of the higher occasion that can not meet the demands.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
The utility model subway station is as shown in Figure 1 with the structure of the aeration-cooling unit of heat pipe heat reclamation type evaporative cooling; Comprise two passages up and down that laterally arrange; Be respectively return air channel and air intake passage; Gravity type heat pipe heat exchanger 3 is arranged between return air channel and the air intake passage; In the air intake passage, comprise fresh wind port 1, first filter 2, gravity type heat pipe heat exchanger 3 new wind sides, material filling type direct evaporative cooler 4, pressure fan 5 and air outlet 6 successively, between gravity type heat pipe heat exchanger 3 new wind sides and the material filling type direct evaporative cooler 4, two interchannel machine unit shell walls are provided with return air inlet b10 up and down by the air approach axis.In the return air channel, comprise return air inlet a7, second filter 8, high-pressure sprayer 9, gravity type heat pipe heat exchanger 3 return side, water fender 11, exhaust blower 12 and exhaust outlet 13 successively by the air approach axis.
The utility model adopts heat reclamation device and the compound structure of evaporation-cooled device, and fresh wind port 1, first filter 2, gravity type heat pipe heat exchanger 3 new wind sides, material filling type direct evaporative cooler 4, pressure fan 5 and air outlet 6 have been formed evaporation-cooled device; Return air inlet a7, second filter 8, high-pressure sprayer 9, gravity type heat pipe heat exchanger 3 return side, water fender 11, exhaust blower 12 and exhaust outlet 13 are formed heat reclamation devices.
Adopt heat reclamation device and the compound structure of evaporation-cooled device, can realize air etc. but clammy.
In the evaporation-cooled device, in the passage of the new wind side of gravity type heat pipe heat exchanger, arrange material filling type direct evaporative cooler 4, can further strengthen cooling-down effect, play a part again to purify air simultaneously.
The course of work of the utility model unit is: after outdoor new wind filters dust through first filter 2 through fresh wind port 1; Carrying out first order cooling through the new wind side of gravity type heat pipe heat exchanger 3 handles; Carry out second level cooling (humidification) through material filling type direct evaporative cooler 4 then and handle, after the air of pressure fan 5 after will handling send in the subway hall through air outlet 6.Indoor return air reduces the temperature of return air through second filter 8, when high-pressure sprayer 9 purifies air through return air inlet a7; After the return side of gravity type heat pipe heat exchanger 3 is carried out the caloic exchange; Through water fender 11, the air that at last will absorb heat by exhaust blower 12 drains into outside the subway through exhaust outlet 13.
During the broiling summer; Air returning valve through regulating return air inlet b10 place is regulated the return air amount; Mix with process gravity type heat pipe heat exchanger 3 pretreated new wind; Handle through the secondary cooling (humidification) of material filling type direct evaporative cooler 4 again, send in the subway by pressure fan 5 at last, thereby reduce operation energy consumption.
The new wind side of gravity type heat pipe heat exchanger 3 and return side are during in the winter time with summer operation, and effect is opposite, thereby the outer new wind of subway is carried out The pre-heat treatment, reach the purpose of recuperation of heat.
