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, eliminates 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 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 by the temperature blown after heat exchange to 20
DEG C or so, it can set corresponding wind pushing temperature according to actual condition of blowing, eliminate cooling in summer operating mode fresh air handining unit again
Thermal energy consumption.
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 eliminates the thermal energy consumption again of summer air-treatment unit, provides and a kind of eliminates cooling in summer operating mode thermal energy consumption again
Fresh air air-treatment unit.
The technical solution of the utility model is：
A kind of fresh air air-treatment unit for eliminating cooling condition thermal energy consumption again, the fresh air air-treatment unit are used for
Central air conditioner system, the fresh air air-treatment unit are unitary air handling unit, and the combined type fresh air handining unit is taken
Modular form integrates multiple functions section, including units such as surface cooling section, bringing-up section, fan section, fillter section, wind outlet sections
One section or several sections of body；It looks up from the stream of fresh air, heat is set after combined type fresh air air-treatment unit surface cooler section
Exchange section carries out heat exchange by surface cooler treated cold fresh air and outdoor fresh air；From position, heat exchange segment is arranged on
The downstream side of surface cooler 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 be 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, the wind pushing temperature of processing to requirement eliminates
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 utility model.
Reference sign：Temperature sensor 1, first flow regulating valve 2, second flow regulating valve 3.
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 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 afterwards.Room air is inhaled by air-introduced machine
Enter, discharged from exhaust outlet.It in addition, after outdoor wind is cooled, 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, so as to eliminate cooling condition fresh air air-treatment unit reheating energy consumption；From position, heat exchange segment is arranged on 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 this case eliminates 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 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 according to actual condition of blowing outside regulation room
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.
