Description
Technical field
The utility model relates to a kind of airduct type variable air rate residential central air conditioning; It can be applicable in villa, household suite and the small commercial building.
Background technology
Residential central air conditioning mainly is divided three classes, i.e. airduct type, fan coiler type and refrigerant multi-type.Airduct type residential central air conditioning is simple in structure, and is reliable, and with respect to other two classes residential central air conditioning, the initial cost of system is less, is convenient to concentrate the purified treatment air and introduces new wind, and indoor air quality is good.Airduct type variable air rate residential central air conditioning is that each air-conditioned room independently is equipped with a vav terminal; Vav terminal can be according to the variation of the deviation of room actual temperature and design temperature, regulate the size of terminal interior throttle opening according to certain control algolithm, thereby regulate the size of the air quantity of sending into each air-conditioned room continuously, realize that the independence of each indoor air temperature in air conditioned building is accurately controlled.In the variable air rate residential central air conditioning, when the air-conditioned room load changed, vav terminal was adjusted the aperture of terminal interior air-valve, and at this moment header pipe's air-supply static pressure is ensued variation.And in order to reduce interfering with each other between different ends or the air conditioning area, realize independent partitions control then needing the air-supply static pressure that keeps certain.In order to realize control to the air-supply static pressure, in the variable air rate residential central air conditioning, adopt speed-changing draught fan as pressure fan usually, speed-changing draught fan is then driven by frequency converter; Adopt air-supply static pressure transducer (air minute-pressure difference transmitter) to measure the air-supply static pressure, variation with the total air output of reflection system, air-supply static pressure controller is regulated rotation speed of fan to change total air output then according to the variation of air-supply static pressure, realizes the constant control of air-supply static pressure.The speed-changing draught fan that employing is driven by frequency converter is as the variable air rate residential central air conditioning of pressure fan, though can realize good air-supply static pressure control, thus guarantee the independent control of each air-conditioned room; It is relatively poor that but equipment drops into expense height, system complex, stability and reliability.。
Summary of the invention
Existing airduct type variable air rate residential central air conditioning causes equipment input expense height, system complex, stability and reliability relatively poor owing to adopt the speed-changing draught fan that is driven by frequency converter.In order to overcome above these shortcomings, the utility model provides a kind of variable air rate residential central air conditioning that has air-supply static pressure control module; It allows the user according to the scene needs to be installed, and freely sets required air-supply static pressure; It can regulate total air output of air-conditioning system continuously, realizes the constant control of air-supply static pressure, to guarantee the independent control of each air-conditioned room.
The technical scheme that its technical problem that solves the utility model adopts is: on the header pipe of this airduct type variable air rate residential central air conditioning, an air-supply static pressure control module is installed.This air-supply static pressure control module comprises an air-supply static pressure transducer (air minute-pressure difference transmitter), pi controller, air-valve and air-valve driver.The air-supply static pressure transducer is measured the air-supply static pressure at header pipe place in real time, and measured air-supply static pressure sent into pi controller, pi controller is according to the actual measured value of air-supply static pressure and the deviation of setting value, according to certain control algolithm, regulate the size of valve area in the control module by the air-valve driver, thereby change total air output of system, realize the constant control of air-supply static pressure.
The beneficial effects of the utility model are that this airduct type variable air rate residential central air conditioning can be realized the good control of static pressure of blowing, thereby guarantees the independent control of each air-conditioned room effectively; And system is stable, reliable, and investment of equipment is few.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic diagram of structure of the present utility model;
Among the figure, 1. new wind control valve, 2. return air control valve, 3. air filtration and purification apparatus, (when air conditioner was in refrigerating operaton, work was evaporimeter to 4. direct expansion formula air-conditioning coil pipe; When air conditioner was in heating operation, then working was condenser), the 5. adjustable outdoor unit (comprising compressor, throttling arrangement, heat exchanger and blower fan) of ability, 6. pressure fan, 7. air themperature transmitter, 8. air-supply static pressure transducer (air minute-pressure difference transmitter), 9. vav terminal, 10. air diffuser, 11. temperature controller, 12. air-supply static pressure control modules, 13. bypass regulator valves, 14. the air-treatment case, 15. air-valves.
The specific embodiment
In the accompanying drawing illustrated embodiment, the applied air conditioning area of this airduct type variable air rate residential central air conditioning only has two rooms, so only be equipped with two vav terminals; But the utility model is equally applicable to institute's band room number greater than plural air conditioning area, and each air-conditioned room is equipped with a vav terminal with each.
In Fig. 1, mix with return air via the new wind of new wind control valve (1) via return air control valve (2), after mixed air carried out purified treatment via air filtration and purification apparatus (3), the wet exchange of heat took place in the cold-producing medium in direct expansion formula air-conditioning coil pipe (4) is located and managed; After air after treatment boosted through pressure fan (6), a part was via directly being back in the backwind tube behind bypass airduct and the bypass air-valve (13), and another part is then via the vav terminal that is assigned to each room behind the header pipe (9); The size of the deviation of terminal room temperature actual value that is sensed according to each room temperature controller (11) and setting value, regulate the size of throttle opening in its end continuously according to certain control algolithm, thereby control to adjust the size of sending into the air quantity of each air-conditioned room via air diffuser (12).In addition, the accurate independent control in order to ensure each room temperature is equipped with an air themperature transmitter (7) and an air-supply static pressure transducer (8) on the header pipe of this airduct type variable air rate residential central air conditioning; Can be by the air conditioner that direct expansion formula air-conditioning coil pipe (4) and outdoor unit (5) are constituted according to the variation of the measured wind pushing temperature of this air themperature transmitter (7), the ability of regulating air conditioner automatically according to certain control algolithm is to be controlled at setting value with wind pushing temperature.It is certain that the rotating speed of pressure fan (6) keeps; Utilize air-supply static pressure control module (12), bypass airduct and air-supply static pressure transducer (8) to control the air-supply static pressure, with total air output of regulating system.When the rising of air-supply static pressure, when promptly the required air output of system reduced, air-supply static pressure control module was turned its incidental air-valve (15) aperture down, increases the air quantity that refluxes via the bypass airduct, and static pressure is controlled at set-point blowing; When the air-supply static pressure reduced, the static pressure of then blowing control module was transferred big its air-valve (15) aperture, increases air output, realized the adjusting control of air-supply static pressure.The return air in each room is pooled to the return air house steward after via return air arm separately, is led by the return air house steward and gets back to air-treatment case (14).
