Abstract
A device for controlling the air output at the tail end of a task air conditioning is characterized in that an electrically operated valve is arranged at the straight pipe section of a Venturi tube, a pressure difference measuring point is respectively arranged on the tube wall at the inlet of the Venturi tube and the tube wall at half of the length of the throat of the Venturi tube, the pressure difference measuring points are connected with pressure difference flow meters through a leather hose respectively, the pressure difference flow meters are connected with a Venturi flow controller through a conducting wire after converting the analogue signals into electrical signals, the Venturi flow controller is connected with the electrically operated valve through the conducting wire, and the opening degree of the electrically operated valve of an actuating mechanism is controlled through electrical signals. The device has simple structure, and is convenient to use; since the structure of a throttling element Venturi is adopted, and an air volume controller and an electric control valve are mounted at the same time, the control of the air output is realized, the cost is low, the accuracy in measurement is precise, and the requirement of personal for thermal environment can be satisfied. The device for controlling the air output at the tail end of the task air conditioning is suitable for the air output control at the tail end in the air supply mode of the task air conditioning.
Description
Technical field
The utility model relates to the heating ventilation and air-conditioning technical field, is specifically related to the control device of the terminal air-supply of a kind of task air conditioning air quantity.
Background technology
Increasingly serious along with energy problem improves efficiency of energy utilization and becomes the focus that people pay close attention to; Add that the mankind are more and more higher to the requirement of living environment quality, people begin the research of individual blowing air-conditioning is more and more paid attention to.Yet traditional centralized air-conditioning is aspect using energy source and to satisfy the deficiency that high-quality living environment aspect showed more and more obvious.Therefore, Bauman etc. have simulated the annual energy consumption of the next offices of California weather conditions, the individual blowing system of Table top type can reduce 18% energy consumption for cooling and total power consumption of 9%, mix supply air system entirely than traditional VAV, the individual blowing system with local fan and radiant panel roughly not can save energy 6%.
Measure the measurement mechanism that flow adopts Pitot tubular type or hot line more in the existing air-conditioning system, but in personalized task air conditioning air-supply, because its air output is less relatively, it is accurate inadequately to measure flow, make troubles to the automatic control adjusting, the hot-wire cost is higher, and uses easily in airduct and wear out, and influences measurement result.
The utility model will design a kind of microenvironment venturi variable flow buret of regulating control.Regulate control air-supply air quantity by this device, can make the air-supply of microenvironment reach optimum state.Such device does not use precedent at present at home and abroad, and research report in this respect is rarely found simultaneously.
Summary of the invention
The utility model discloses the terminal air-supply of a kind of task air conditioning air quantity controller, can effectively overcome that prior art exists because air output is measured inaccuracy, the cost height causes being difficult to realize the air output defective of control automatically.The utility model adopts venturi unsteady flow buret control air-supply air quantity, not only can enlarge the air-supply air measuring and the control range of task air conditioning, satisfies the requirement of people to thermal comfort simultaneously.
The terminal air-supply of a kind of task air conditioning air quantity controller, comprise Venturi tube, it is characterized in that: described Venturi tube is provided with motor-driven valve at leading portion straight length place, at Venturi tube inlet tube wall place and throat 1/ 2 length tube wall places the differential pressure measurement point is set respectively, differential pressure measurement point is connected by leather hose with differential pressure flowmeter respectively, after differential pressure flowmeter is the signal of telecommunication with analog signal conversion, be connected with the venturi flow controller by lead, the venturi flow controller is connected with motor-driven valve by lead, by the aperture of signal of telecommunication control executing agency motor-driven valve.
The utility model is simple in structure, and is easy to use, owing to adopt the structure of restricting element venturi, blast volume controller and electric control valve have been installed simultaneously, can have been realized the control to air output, not only cost is low, and certainty of measurement is accurate, can satisfy the requirement of individual to thermal environment.The utility model can be used for terminal air quantity control in the task air conditioning air supply mode.
