Abstract

A method for regulating the air temp and improving air quality in air-conditioned room features that the outdoor fresh air and indoor return air take part in heat exchange in a ventilating heat exchanger and then respectively comes in room or is exhausted to outdoor space. Its system is composed of coiled tube of fan, air returning inlet of air conditioner, ventilating heat exchanger, fresh air inlet, exhaust outlet, indoor air feeding port, indoor air return port, air feeding pipe, and returning pipe and exhaust pipe.

Description

The method and system that a kind of air-conditioned room air temperature modification and air quality improve
Technical field
The invention belongs to field of environment engineering technology, relate to a kind of method and system of air-conditioned room air conditioning.
Background technology
The adjusting of present air-conditioned room room air can be divided into three kinds: the one, and closed system: indoor air circulation is used, the load of air-conditioning unit only need keep indoor temperature and the heat radiation of air-conditioned room body of wall gets final product, so better economy, but because long-time indoor circulation air, the airborne CO of using 2Concentration can constantly raise, and airborne suspended material also can be full of with the circulation of room air indoor, thereby make IAQ worse and worse; The 2nd, straight-flow system: indoor return air is directly discharged by exhaust duct, outdoor new wind is handled the back by ventilation unit and is directly sent into indoor by air supply duct, advantage is that air quality is good, but the required whole air-conditioning units of energy of temperature that the new wind-warm syndrome degree in the inlet chamber will reach indoor requirement are born, energy consumption is big, and is uneconomical; The 3rd, return air+VMC: handle by ventilation unit again after the indoor return air of outdoor new wind and part mixes, send into indoor by air supply duct, advantage is that air quality improves, indoor return air energy obtains the part utilization, but the new wind in the inlet chamber will reach the required energy major part of temperature of indoor requirement still will be born by the air-conditioning unit, energy consumption is also bigger, neither very economical.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned three kinds of existing methods, providing a kind of can cut down the consumption of energy, and improves energy utilization rate, the air-conditioned room air temperature modification of the economy of enhancing air-conditioning unit and the method and system that air quality improves.
The method that air-conditioned room air temperature modification provided by the invention and air quality improve adopts air-conditioning unit device to add the air themperature and the quality adjustment mode of ventilation unit, new wind in the ventilation unit all adopts outdoor air, in ajutage 11 and indoor air outlet 4 inlet chambers, indoor return air is discharged outdoor by exhaust duct 13 and outdoor exhaust outlet 3, it is characterized in that: outdoor new wind is introduced into ventilation heat exchanger 1 by indoor air outlet 4, then by in indoor air outlet 4 inlet chambers, indoor return air also is introduced into ventilation heat exchanger 1 by indoor return air inlet 5, discharges outdoor by outdoor exhaust outlet 3 then; Outdoor new wind and indoor return air conduct heat each other 1 li of ventilation heat exchanger but do not mix.
The system that air-conditioned room air temperature modification provided by the invention and air quality improve is made up of air-conditioning unit device and ventilation unit, and wherein air-conditioning unit device includes fan coil 6, air-conditioning unit return air inlet 7; Ventilation unit includes outdoor new wind inlet 2, outdoor exhaust outlet 3, indoor air outlet 4, indoor return air inlet 5, ajutage 11, backwind tube 12, exhaust duct 13 is characterized in that: between outdoor new wind inlet 2 and indoor air outlet 4, and a ventilation heat exchanger 1 is installed between outdoor exhaust outlet 3 and the indoor return air inlet 5,1 li of ventilation heat exchanger, outdoor new wind and indoor return air do not mix, and only relying on conducts heat finishes exchange heat, and the major part that outdoor so new wind reaches the temperature energy needed of indoor requirement is provided by the return air of 1 li of ventilation heat exchanger, have only the fraction energy to provide, thereby saved the energy consumption of air-conditioning unit by fan coil 6.

1. ventilation heat exchanger; 2. outdoor new wind inlet; 3. outdoor exhaust outlet; 4. indoor air outlet; 5. indoor return air inlet; 6. fan coil; 7. air-conditioning unit fan coil return air inlet; 8. air-conditioning unit water pipe; 9. muffler; 10. filter; 11. ajutage; 12. backwind tube; 13. exhaust duct.
The specific embodiment
At first according to illustrated in figures 1 and 2, adopt the conventional air-conditioning mounting means with air-conditioning unit fan coil 6,7 Installation and Debugging of air-conditioning unit fan coil return air inlet are good, and then on the certain position in room routinely mounting process successively with ventilation heat exchanger 1, outdoor new wind inlet 2 and ajutage 11 and indoor air outlet 4, outdoor exhaust outlet 3 and exhaust duct 13, indoor return air inlet 5 and backwind tube 12, muffler 9, filter 10 Installation and Debugging are good.Arrow is represented the flow direction of wind among Fig. 2.
In the technical program, air-conditioning unit fan coil 6 is mainly born indoor temperature load and body of wall heat radiation; Outdoor new wind enters air-conditioned room by indoor air outlet 4 after outdoor new wind inlet 2 enters ventilation heat exchanger 1 preheating (precooling), indoor return air emits by outdoor exhaust outlet 3 after ventilation heat exchanger 1 heat release (heat absorption).New wind in outdoor new wind enters the mouth 2 inlet chambers, its temperature will reach can being born by the return air of 1 li of ventilation heat exchanger more than 70% of energy of the required exchange of temperature of indoor requirement, 8 need of air-conditioning unit are kept indoor temperature and body of wall heat radiation and 30% following novel wind energy load and are got final product, thus the energy consumption of greatly reducing.The exchange of new wind and return air energy is finished by ventilation heat exchanger 1 in this method simultaneously, and the two has only energy exchange in ventilation heat exchanger, does not mix, and the quality of new wind is guaranteed.
Method and system of the present invention is applied to be positioned at grass villa four seasons No. 53 (220 square metres of construction areas) of Daxing District, Beijing grass villa, and used air-conditioning unit is 1 of a NLHP-250 type source pump, Winter heat supply amount 22kw, summer cooling amount 20kw; Ventilation heat exchanger 1 usefulness in the VMC be FY-01KZDY2A type ventilation heat exchanger, the pipe arrangement diameter is 250mm, new wind ventilation is 940m 3/ h, waste heat recovery in winter amount is 7.5kw, heat recovery rate 70%, whole system energy-conservation 30%; Summer, new wind ventilation was 867m 3/ h, the cold recovery amount is 1.56kw, the cold recovery rate also can reach 70%, whole system energy-conservation 6.1%.New wind ventilation is big more, and energy-saving effect is obvious more.
