Description
Technical field
The invention belongs to a kind of improved fresh air air-treatment units, pass through the improvement fresh air air-treatment unit summer in this case
Season cooling condition processing procedure, utilize outdoor fresh air with by surface cooler handle fresh air heat exchange, eliminate cooling in summer work
The thermal energy consumption again of air-treatment unit under condition.
Background technology
With the rapid 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 of hot and cold energy in control air-conditioning system, while being also the decision facility for changing air condition.Combined type is empty
It adjusts unit 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.The consumed electricity of unitary air handling unit is empty 25% or so
It consumes energy in adjusting system most one of settings.
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 qualitative indoor temperature, to indoor air-supply.
In the process of refrigerastion process, air reheating is in such a way 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）.Indoor design room air conditioner design temperature is required to take 26 DEG C according to Air-conditioner design, supply air temperature difference takes 6 DEG C,
Normal practice is to use 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
It manages and increases by one section of heat-exchanger rig before unit surface cooler, will be blown by surface cooler and be exchanged heat with outdoor fresh air, and entered
Mounting temperature sensor on fresh air air supply duct before interior installs flow tune on outdoor air inlet or outdoor wind pipe
Valve is saved, flow control valve is opened size and is adjusted according to temperature sensor, is promoted to 20 by the temperature blown after heat exchange
DEG C or so, it can set corresponding wind pushing temperature according to practical condition of blowing, eliminate cooling in summer operating mode fresh air handining unit again
Thermal energy consumption.
Invention content
The technical problem to be solved by the present invention is to handle fresh air under unit cooling in summer operating mode to conventional air and process
Journey eliminates the thermal energy consumption again of summer air-treatment unit, provides a kind of fresh air for eliminating cooling in summer operating mode thermal energy consumption again
Air-treatment unit.
The technical scheme is that：
A kind of fresh air air-treatment unit for eliminating cooling condition thermal energy consumption again, the fresh air air-treatment unit is for center
Air-conditioning system, the fresh air air-treatment unit are unitary air handling unit, and the combined type fresh air handining unit takes module
The form of change integrates the cell cubes such as multiple functions section, including surface cooling section, bringing-up section, fan section, fillter section, wind outlet section
One section or several sections；It looks up from the stream of fresh air, heat exchange is set after combined type fresh air air-treatment unit surface cooler section
Section carries out heat exchange by surface cooler treated cold fresh air and outdoor fresh air；From position, heat exchange segment setting is cold in table
The downstream side of device section.
After the outdoor wind is cooled, it is sent at fresh inlet.
In the end of heat exchange segment, mounting temperature sensor on the fresh air air supply duct before getting in, outdoor into
Flow control valve is installed on wind or outdoor wind pipe, flow control valve is opened size and is adjusted according to temperature sensor.
Using the technical program, cold fresh air is heated by outdoor fresh air.The technical program is related to a set of fresh air system, and
The outdoor wind system of a set of heating.
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, can be with
It is required according to wind pushing temperature, adjusts the flow control valve of outdoor air inlet or outdoor air inlet, processing to desired wind pushing temperature is eliminated
Fresh air air-supply thermal energy consumption again（Temperature is promoted from 10 DEG C to 20 DEG C or so (wind pushing temperatures)）.
Description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Reference sign：Temperature sensor 1, first flow regulating valve 2, second flow regulating valve 3.
Specific implementation mode
Below in conjunction with the accompanying drawings and preferred embodiment is further described with regard to technical scheme of the present invention.
As shown in Figure 1, fresh air enters fillter section impurity screening from fresh inlet, cooled down in surface cooling section.It is exchanging heat
Section, cold fresh air is heated by the higher outdoor wind of the temperature from outdoor introducing, sent to the room later.Room air is inhaled by air-introduced machine
Enter, is discharged from exhaust outlet.In addition, after outdoor wind is cooled, it is not discharged into air, but is sent at fresh inlet.
The mounting temperature sensor on heat exchange segment fresh air air supply duct is installed on outdoor air inlet and outdoor wind pipe
Flow control valve, flow control valve are opened size and are adjusted according to temperature sensor, temperature sensor temperature setting air-supply temperature
Angle value, to eliminate cooling condition fresh air air-treatment unit reheating energy consumption；From position, heat exchange segment is arranged in surface cooler
The downstream side of section.Using outdoor fresh air and the fresh air heat exchange handled by surface cooler, consume under cooling in summer operating mode at air
Manage the thermal energy consumption again of unit.
To realize that the thermal energy consumption again under cooling condition is eliminated in this case, in present case, increase after air-treatment unit surface cooling section
Add a heat exchange segment, will be exchanged heat with outdoor fresh air by the air-supply of surface cooler, carried by the temperature blown after heat exchange
20 DEG C or so (wind pushing temperatures) are raised to, by the temperature sensor of installation, can be blown outside regulation room according to practical condition of blowing
Flow control valve, make air-supply handle wind pushing temperature, need not heat can be sent to air-conditioned room, eliminate cooling in summer work
The thermal energy consumption again of fresh air air-treatment unit under condition.The improved air-treatment unit after surface cooler by increasing heat exchange
Section eliminates air-treatment unit reheating energy consumption.
