The variable air rate exhaust valve.
Preferably, second static pressure transducer is arranged near the air exhaust branch pipe of distalmost end.
VAV(Variable Air Volume) VAV control, air conditioning system with variable be a kind of by changing air output
The air-conditioning system of indoor temperature and humidity is adjusted, is chiefly used in comfort air conditioning system system.And the laboratory energy-saving ventilating air of the utility model
System uses for reference above-mentioned air-conditioning system, is applied in laboratory, to obtain energy-efficient technical effect.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of laboratory energy-saving ventilation system of the best embodiment of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below.
As shown in Figure 1, a kind of laboratory energy-saving ventilation system of the utility model includes pressure fan 1 and exhaust blower 7, air-supply
Machine 1 connects air supply tube 4, and exhaust blower 7 connects air-exhausting duct 5, and the air outlet of air supply tube 4 and the air inlet of air-exhausting duct 5 are arranged at reality
Test interior.One first static pressure transducer 9 is set on air supply tube 4, and the first static pressure transducer 9 connects pressure fan 1, sets on air-exhausting duct 5
One second static pressure transducer 10 is set, the second static pressure transducer 10 connects exhaust blower 7.Pressure fan 1 and exhaust blower 7 include variable-frequency electric
Machine, so that its air quantity is adjustable.
Variable air rate blow valve 2 is provided on air supply tube 4.Several air exhaust branch pipes, each air draft are arranged in parallel on air-exhausting duct 5
A variable air rate exhaust valve 3 is respectively provided on branch pipe, and the second static pressure transducer 10 is arranged near the air exhaust branch pipe of distalmost end.
Variable air rate blow valve 2 and variable air rate exhaust valve 3 are connected by connection 8, and are passed with the first static pressure transducer 9, the second static pressure
Sensor 10 connects.
Using the laboratory variable air ventilating system of constant static-pressure method, in the position of 5 proximal end of air-exhausting duct, setting static pressure is sensed
Device (the first static pressure transducer 9 and the second static pressure transducer 10), when 3 aperture of laboratory ventilation tail-end variable wind amount exhaust valve changes
When, resistance of pipe system will also generate variation, and the first static pressure transducer 9, which just can measure static pressure in air supply tube 4, to be changed, and set with static pressure
Value is compared, and is adjusted 1 revolving speed of pressure fan and air quantity, had not only been met the air-conditioning requirement in laboratory, but also ventilating system can be made efficient
It is run under power save mode.In addition, the utility model also has the advantage that
(1) system response is timely.Constant static-pressure genealogy of law unified test point is few, and the static pressure in air supply tube 4 can be rapidly with experiment
Room end air quantity changes and change, thus reply end air quantity demand frequently change and system response time in terms of with larger
Advantage；
(2) high system safety.Constant static-pressure method is according to end demand control system set point static pressure, entire control system
Operand obtained effectively simplifying, system stability is good, be conducive to improve laboratory safety.
(3) energy saving of system is good.The setting of minimum operation air quantity makes this under the use of variable-frequency motor and night operating condition on duty
System can obtain preferable energy-saving effect.
Above embodiments are only the one such embodiment of the utility model, and the description thereof is more specific and detailed, but simultaneously
Therefore it cannot be interpreted as that a limitation on the scope of the patent of the present invention.It should be pointed out that for the ordinary skill of this field
