Concentrate recuperation of heat region independently to control air conditioning systemTechnical field
The present invention relates to a kind of concentrated recuperation of heat region and independently control air conditioning system.
Background technology
In recent years, new air exhaust heat recovery system has been widely used and has developed, and in general mainly comprises dispersion (level) system and concentrates two kinds of system forms of (vertically) system.Decentralized system, the independent recuperation of heat unit arranging, controls flexibly, but huge because of equipment profile, has the machine room gross area and takies larger shortcoming; Central system, the recuperation of heat unit equipment of concentrated setting is placed on Special machine room, and machine room takies little, but has the shortcoming of hierarchical control difficulty.
Summary of the invention
The present invention uses in new air exhaust heat recovery technology process in order to solve, and adopts decentralized system to take the machine room gross area excessive or adopt central system decentralised control difficult problem, has proposed a kind of concentrated recuperation of heat region and has independently controlled air conditioning system.
The technology of the present invention, in conjunction with concentrating and disperseing two kinds of system forms technical advantage separately, by the core technology of VFC, proposes a kind of concentrated recuperation of heat region and independently controls air conditioning system, to solve said system deficiency.
An air conditioning system is independently controlled in concentrated recuperation of heat region, it is characterized in that, comprises new blower fan group, quiet pressure fan, Electric air valve;
Described new blower fan group is arranged in deck or Special machine room, and new wind arrives indoor constant enthalpy point by the full recuperation of heat runner precooling in new blower fan group or preheating post processing, by the quiet pressure fan arranging in each floor furred ceiling, delivers to each floor;
On each floor exhaust duct, corresponding Electric air valve is set.
Described new blower fan group comprises pressure fan, controls the compressor variable frequency controller of the exhaust blower frequency-variable controller of the pressure fan frequency-variable controller of pressure fan, exhaust blower, control exhaust blower, compressor, control compressor.
The quiet pressure fan start signal of each floor reaches the pressure fan frequency-variable controller in new blower fan group, and pressure fan frequency-variable controller is controlled pressure fan frequency conversion according to actual air output.
Each floor Electric air valve start signal reaches the exhaust blower frequency-variable controller in new blower fan group, and exhaust blower frequency-variable controller is controlled exhaust blower frequency conversion according to actual exhaust air rate.
Described compressor is according to wind pushing temperature VFC.
Concentrate recuperation of heat region independently to control air conditioning system, concentrate new air exhaust heat is reclaimed and processed, every layer of resh air requirement of decentralised control, saves the energy and machine room area.
The present invention compared with prior art, has the following advantages:
(1) new air exhaust heat recovery technology, saves the energy;
(2) heat recovery fresh air unit is concentrated and is placed on roofing or special-purpose unit, and every floor face does not need independently new Ventilator Room, only needs to lift common pressure fan, saves construction area;
(3) the new blower fan of each floor can independently be controlled, concentrate heat recovery fresh air unit can be according to the new wind demand of reality by blower fan and compressor bank converter technique realizes air quantity and temperature regulates, save the energy.
Accompanying drawing explanation
Fig. 1 is system schematic of the present invention, has only comprised the critical piece of system;
1. the new blower fan group in full recuperation of heat roof;
2. pressure fan;
21. frequency-variable controllers;
3. exhaust blower;
31. frequency-variable controllers;
4. compressor;
5. frequency-variable controller;
6. quiet pressure fan;
7. Electric air valve.
The specific embodiment
System of the present invention is as shown in Figure 1: system is comprised of critical pieces such as the new blower fan group 1 in full recuperation of heat roof, quiet pressure fan 6, Electric air valves 7.The new blower fan group 1 in full recuperation of heat roof comprises pressure fan 2, exhaust blower 3, the frequency-variable controller 21 of controlling respectively pressure fan 2 and exhaust blower 3 and frequency-variable controller 31, compressor 4, controls the frequency-variable controller 5 of compressor 4.
The new blower fan group 1 of deck or the full recuperation of heat of Special machine room concentrated setting roof, new wind to indoor constant enthalpy point, is delivered to each floor by the quiet pressure fan 6 in each floor furred ceiling by full recuperation of heat runner precooling preheating post processing.Each floor exhaust duct arranges corresponding Electric air valve 7.
The major control logic of native system:
1. the Electric air valve on each floor exhaust duct 7 and the chain control of exhaust blower 3.
2. quiet pressure fan 6 start signal of each floor reach pressure fan 2 frequency-variable controllers 21 of the new blower fan group 1 in full recuperation of heat roof, and the actual air output under the actual fan operating numbers correspondence of frequency-variable controller 21 calculating is to control pressure fan 2 frequency conversions.
3. each floor Electric air valve 7 start signal reach new blower fan group 1 exhaust blower 3 frequency-variable controllers 31 in full recuperation of heat roof, and the actual exhaust air rate under the actual fan operating numbers correspondence of frequency-variable controller 31 calculating is to control exhaust blower 3 frequency conversions.
Compressor 4 according to wind pushing temperature by frequency-variable controller 5 VFC.
The main structure thought of system shown in the present is: recuperation of heat is concentrated in new air draft, focuses on decentralised control.Only at roofing or Special machine room, place new wind devices, every floor face does not need independently new Ventilator Room, saves machine room area; The new blower fan of each floor can independently be controlled, main frame can be according to the new wind demand of reality by blower fan and compressor bank converter technique realizes air quantity and temperature regulates, new air draft is concentrated recuperation of heat and is processed, and saves the energy, and can independently control, and avoids energy waste.
