The air inlet and the air outlet are respectively positioned at both sides of the box body. The motor and the blower are installed in the box body. The blower is driven by the motor. The present invention provides an air conditioning system with variable air volumes, which has the advantages of favorable performance, simple control and low price.
Description
Technical field:
The present invention relates to the central air conditioner system technical field, especially the multi-blower air conditioning system with variable wind flow field.
Background technology:
Existing air conditioning system with variable is a kind of central air conditioner system, by indoor thermostat; Air quantity variable end device; The air-conditioning unit; New wind control module; The air draft blower fan; Six parts such as blast volume controller are formed.
The shortcoming of existing air conditioning system with variable is: the control method complexity; Cost an arm and a leg; The stability of a system is poor; Indoor new wind is usually not enough.
Summary of the invention:
The objective of the invention is to solve at present the control method complexity that air conditioning system with variable both at home and abroad exists, cost an arm and a leg, the stability of a system is poor, and indoor new wind is subject matter such as deficiency usually, provides a kind of performance good, and control is simple, the air conditioning system with variable that price is low.
Another object of the present invention is to improve the energy saving of air conditioning system with variable.
For realizing purpose of the present invention, multi-blower air conditioning system with variable wind flow is made up of six parts: multi fan variable air rate indoor thermostat, variable blowing rate box, air-conditioning unit, new wind control module, air exhausting device, intelligent frequency-conversion controller;
Variable blowing rate box is made up of box body, motor, blower fan, air inlet and air outlet, and air inlet and air outlet are opened respectively in the box body both sides, and motor and blower fan are contained in the box body, and blower fan is by driven by motor;
The multi-blower air conditioning system with variable wind flow working method is that indoor thermostat regularly constantly detects indoor temperature, and indoor temperature and the design temperature that detects compared, when difference appears in detected temperatures and design temperature, temperature controller changes the rotating speed of variable blowing rate box blower fan, increase or reduce and send into indoor air quantity, till indoor temperature reverts to design temperature;
Indoor thermostat is when regulating the variable blowing rate box rotation speed of fan, pass through serial communication mode, import signal into the intelligent frequency-conversion controller, the intelligent frequency-conversion controller reaches the purpose that changes air quantity according to total air output of the pressure fan of the air quantity sum adjusting air-conditioning unit of each variable blowing rate box.The resh air requirement control of multi fan variable air volume system has two kinds of methods: newly wind blower fan method and fixedly pressure differential method, these two kinds of control methods all can be controlled accurately and send into indoor resh air requirement.
As a further improvement on the present invention, air-conditioning system will be sent into the air-conditioning unit from the air part of indoor absorption mix the mist that forms primary retirn air and new wind with new wind facies indoor through the variable blowing rate box input.
As a further improvement on the present invention, the return air inlet that multi-blower air conditioning system with variable wind flow increases links with variable blowing rate box, therefore the gas that enters variable blowing rate box is the treated primary retirn air that come by primary retirn air air-conditioning unit and the mixing air of new wind, and the secondary return air that directly enters by the room, after the mixing, send into indoor again by variable blowing rate box.
As a further improvement on the present invention, variable blowing rate box can add reheater, and what variable blowing rate box can be according to the user requires supporting heater element rated voltage 220V, 0.01m
2The front face area heat can reach 1.5kW.
The outstanding advantage of multi fan variable air volume system is: than air conditioning system with variable is more energy-conservation at present, improve 25%～30%, than conventional air-conditioning energy saving of system 50%～60% both at home and abroad; The instability problem of air conditioning system with variable existence both at home and abroad at present and the problem of new wind deficiency have been solved; The price of system is than cheap 3～10 times of at present domestic and international air conditioning system with variable.
Description of drawings:
Fig. 1 is the multi-blower air conditioning system with variable wind flow schematic diagram.
Fig. 2 is a primary retirn air multi-blower air conditioning system with variable wind flow schematic diagram.
Fig. 3 is a secondary return air multi-blower air conditioning system with variable wind flow schematic diagram.
Specific embodiment:
Multi-blower air conditioning system with variable wind flow as shown in Figure 1, this system is by being made up of six parts: indoor thermostat 1, variable blowing rate box 2, air-conditioning unit 3, new wind control module 4, air exhausting device 5, intelligent frequency-conversion controller 6;
Outside air absorbs through new wind control module 4 and enters air-conditioning system, and the air after air-conditioning unit 3 will be handled is in variable blowing rate box 2 inlet chambers, and air exhausting device 5 is discharged indoor foul atmosphere outdoor;
Intelligent frequency-conversion controller 6 is controlled new wind control module 4 simultaneously and air exhausting device 5 makes the whole system work coordination, the resh air requirement control of multi fan variable air volume system has two kinds of methods: (1) new wind blower fan method and (2) are pressure differential method fixedly, and these two kinds of control methods all can be controlled accurately and send into indoor resh air requirement.
Multi-blower air conditioning system with variable wind flow as shown in Figure 2, this system will send into air-conditioning unit 3 from the air part of indoor absorption simultaneously and form primary retirn airs except that the work of as shown in Figure 1 multi-blower air conditioning system with variable wind flow, primary retirn air is sent into chamber wind with the new wind that new wind control module 4 sucks after air-conditioning unit 3 mixed processing, the work of other devices in the system is with shown in Figure 1 identical.
Multi-blower air conditioning system with variable wind flow as shown in Figure 3, the return air inlet 7 that this system increases links with variable blowing rate box 2 and air-conditioning unit 3, therefore the air that enters variable blowing rate box is except the mixing air of the treated primary retirn air of air-conditioning unit 3 and new wind, also has the secondary return air that directly enters by the room, both are sent into indoor after mixing in variable blowing rate box 2 box bodys again by variable blowing rate box.
Temperature controller that multi-blower air conditioning system with variable wind flow is used and intelligent frequency-conversion controller are produced by Guode Air Conditioner and Refrigerator Industry Co., Ltd., Guangdong, come into the market.
