Abstract
The utility model discloses a kind of fresh air air-treatment units for reducing cooling condition thermal energy consumption again, the fresh air air-treatment unit is used for central air conditioner system, the fresh air air-treatment unit is unitary air handling unit, the combined type fresh air handining unit takes modular form, integrate multiple functions section, one including cell cubes such as surface cooling section, bringing-up section, fan section, fillter section, wind outlet sections section or several sections；It looks up from the stream of fresh air, uncooled fresh air first passes through heat exchange segment, and then described uncooled fresh air is cooled using after surface cooler, and fresh air after cooling carries out heat exchange with uncooled fresh air in heat exchange segment；From position, heat exchange segment is arranged on the upstream side of surface cooler section.Using outdoor fresh air with by surface cooler handle fresh air heat exchange, reduce cooling in summer operating mode under air-treatment unit thermal energy consumption again.
Description
Technical field
The utility model belongs to a kind of improved fresh air air-treatment unit, in this case by improving fresh air air processing machine
The processing procedure of group cooling in summer operating mode using outdoor fresh air and the fresh air heat exchange handled by surface cooler, reduces summer system
The thermal energy consumption again of air-treatment unit under cold operating mode.
Background technology
With the fast development of social economy, promote the rise of public building.To meet the comfort of indoor air quality
Demand, public building usually configure central air conditioner system, and unitary air handling unit is the key that central air conditioner system inscape,
It is the capital equipment for controlling hot and cold energy in air-conditioning system, while is also the decision facility for changing air condition.Combined type is empty
Unit is adjusted to take modular form, integrates multiple functions section, including air mixing section, surface cooling section, bringing-up section, humidification
The cell cubes such as section, fan section, flow equalization section, fillter section, wind outlet section.Unitary air handling unit consumes electricity 25% or so, is empty
It consumes energy in adjusting system one of most setting.
Conventional air handles unit in summer when cooling condition is run, after fresh air is by surface cooler cooling and dehumidifying, until air
Dew point, then using reheating（Using electrical heating, hot water or steam）To after setting qualitatively indoor temperature, to indoor air-supply.
In the process of refrigerastion process, air reheating is in a manner that extra power heats air, and energy consumption is larger, not reasonable.
Under the conditions of summer condition, regular air handles insoenthalpic dew of the unit fresh air by surface cooler post processing to indoor design condition point
Point（Temperature is 10 DEG C）.According to Air-conditioner design indoor design room air conditioner design temperature is required to take 26 DEG C, supply air temperature difference takes 6 DEG C,
Normal practice is using electrical heating, and room is sent into after fresh air is heated to 20 DEG C from dew-point temperature.This patent is at fresh air air
Managing increases by one section of heat-exchanger rig before unit surface cooler, will be blown by surface cooler and exchanged heat with outdoor fresh air, and handed over by heat
The dew-point temperature blown after changing is promoted to 20 DEG C or so, can according to actual condition of blowing, select reheating or be not added be heat-fed into
To air-conditioned room, the thermal energy consumption again under cooling condition is reduced.
Utility model content
The technical problems to be solved in the utility model is to handle conventional air the place of fresh air under unit cooling in summer operating mode
Reason process reduces the thermal energy consumption again of summer air-treatment unit, and providing a kind of reduces cooling in summer operating mode thermal energy consumption again
Air-treatment unit.
The technical solution of the utility model is：
A kind of fresh air air-treatment unit for reducing cooling condition thermal energy consumption again, during the fresh air air-treatment unit is used for
Air-conditioning system is entreated, the fresh air air-treatment unit is unitary air handling unit, and the combined type fresh air handining unit takes mould
The form of block integrates multiple functions section, including cell cubes such as surface cooling section, bringing-up section, fan section, fillter section, wind outlet sections
One section or several sections；It looks up from the stream of fresh air, uncooled fresh air first passes through heat exchange segment, then described uncolled
Fresh air be cooled using after surface cooler, fresh air after cooling and uncooled fresh air carry out heat exchange in heat exchange segment；From
It is seen on position, heat exchange segment is arranged on the upstream side of surface cooler section.
The technical program advantage is that the higher fresh air of the temperature that cold fresh air was originally come in heats, and originally come in
The higher fresh air of temperature is cooled down again by cold fresh air.There was only a set of fresh air system in total.
After increasing heat exchange segment before the surface cooler section of combined type fresh air air-treatment unit, after being handled by surface cooler
Fresh air and outdoor fresh air carry out heat exchange in heat exchange segment, air-supply dew-point temperature is increased to 20 DEG C or so by 10 DEG C, is reduced
Fresh air air-supply thermal energy consumption again（Temperature is promoted from 10 DEG C to 20 DEG C or so）.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and preferred embodiment is further described with regard to the technical solution of the utility model.
As shown in Figure 1, fresh air enters fillter section impurity screening at fresh wind port, fan section provides power for fresh air.In heat
Exchange section, fresh air is from heat exchange segment bottom up to heat exchange segment top, and afterwards into surface cooling section, fresh air is carried out in surface cooling section
Cool-down dehumidification.Fresh air after cooling reenters the lower part of heat exchange segment, goes out from the top of heat exchange segment, subsequently enters heating
Section, enters room from bringing-up section.Room air is sucked by air-introduced machine, is discharged from exhaust outlet.
To realize that this case reduces the thermal energy consumption again under cooling condition, in present case, increase after air-treatment unit surface cooling section
Add a heat exchange segment, will be exchanged heat by the air-supply of surface cooler with outdoor fresh air, pass through the dew point temperature blown after heat exchange
Degree is promoted to 20 DEG C or so, can be selected reheating or is not added with heat to be sent to air-conditioned room according to actual condition of blowing, reduce the summer
The thermal energy consumption again of fresh air air-treatment unit under season cooling condition.The improved air-treatment unit after surface cooler by increasing
Heat exchange segment reduces air-treatment unit reheating energy consumption.
Claims (1)
1. reducing the fresh air air-treatment unit of cooling condition thermal energy consumption again, the fresh air air-treatment unit is used for central air-conditioning
System, the fresh air air-treatment unit are unitary air handling unit, and the combined type fresh air handining unit is taken modular
