Description

Vav terminal automatic temperature-control equipment

Vav terminal automatic temperature-control equipment belongs to the automatic temperature-control equipment in apparatus of air conditioning field, and the air quantity reheat-type air-conditioning system of deciding of known use mainly is made up of air outlet, adjusting device, main air delivery duct, blower fan, connecting pipe.Known adjusting device is for to decide the air quantity reheat-type, and cold and hot wind facies is offset mutually, causes blower fan power consumption to increase, and does not have insulation, noise reduction layer on the adjusting device, is difficult for keeping constant temperature, noise big, and is manual tune switch, inconvenience.

The purpose of this utility model is: be the deficiency that overcomes known technology, a kind of novel vav terminal automatic temperature-control equipment is provided.Not needing under the auxilliary situation that adds the energy variation to compensate the cold or hot variation in room automatically by air output, satisfy the constant temperature requirement, reduce the fan operation time, reach energy-conservation purpose.Insulation is installed on box body wall, reduces material, improve maintenance constant temperature function and reduce noise.

The utility model is achieved in that implication sees the description of drawings part for details among the figure referring to accompanying drawing 1 to 8.Mainly by air outlet, adjusting device, connecting pipe, the vav terminal automatic temperature-control equipment that securing member is formed, it is characterized in that (A) comprises mainly that in the adjusting device 1 that does not need under the heating state to be changed the variation of the cold or thermic load in compensation room automatically by air output air intake interface 9 is arranged on it, the casing 15 of air-out interface 19, be contained in reduction noise and fort adiabator 14 on the casing wall, change air output and indoor cold or crank 2 and valve plate 13 that thermic load balances each other, the direct solenoid valve actuator 7 that spring is arranged in driving that realization valve plate that the crank valve plate rotates opens or turn down, transformer 10, power connection 12, heat detector 18 and connection lead 8,11, valve plate 13 is contained on the casing 15 by axle 3, crank 2 one ends are connected with an end of axle 3, the crank other end is slidingly matched with the axle 5 that moves in crank recess 4 and contacts, axle 5 is connected with the drive rod 6 of actuator 7, actuator 7 is connected by lead 8 with transformer 10, heat detector 18 is connected by lead 11 with transformer 10, (B) air outlet 20 and adjusting device 1 apart arrangement, be connected with pipeline 21 between air outlet 20 and the adjusting device 1, be connected with pipeline 22 between adjusting device 1 and the main air delivery duct 23.This equipment is the capital equipment of air conditioning system with variable, under the situation that does not need to heat, is compensated the variation of the cold of room or load automatically by the variation of air output.Thereby satisfy the constant temperature and the comfort requirement in room.Variable air rate belongs to all-air system.Be in operation and avoided cold-hot counteraction to greatest extent, reduce the fan operation time, the promptly energy-conservation IAQ that improved again.Because the room air output is adjustable, the air quantity in each room can be adjusted size easily, can reduce installed capacity effectively.Be suitable for most many rooms, air quantity variation central air conditioning greatly.Extraneous power supply is delivered to actuator 7 and heat detector 18 by lead 8,11 through joint 12 after transformer 10 rectifications.Actuator is a DC electromagnetic valve, and the valve plate 13 that drives in the casing 15 by drive rod 6, axle 5, crank 2 moves, and promptly " turns down or open " valve plate, realizes the adjusting to air quantity.Spring is arranged in the magnetic valve.The actuatable valve plate recovers fully open position, heat detector 18 and mainly is made up of the contact a of turn-knob 16 controls and b, switch 17.The room temperature automatic control program now is described: be example with the winter, forward the switch door to D place (position in winter), promptly electric contact " O, I " is connected, and turn-knob 16 forwarded to and made electric contact " a " and " b " that certain distance (dispatch from the factory and mix up) be arranged this moment, and warm braw is sent into indoor.When room temperature when the design temperature, " a " contact with " b ", the contact C1 closure of relay J, then magnetic valve D action, drive valve plate turns down gradually to the rotation of S direction, the minimizing of warm braw amount, room temperature slowly descends.When dropping to lower limit, " a " and " b " point disconnects again, the magnetic valve outage, and spring force returns to fully open position by connecting rod crank drive valve plate 13.During summer switch forwarded to C place (position in summer), by graticule rotation turn-knob 16 " a " pin inserted in " b " counterclockwise simultaneously, operation program thereafter states that no longer each room can rotate turn-knob 16 by the mark limit separately like this, with the regulated at will room temperature.The mark limit is that check and correction was demarcated well before equipment dispatched from the factory, and the temperature setting range of general room temperature is 10 to 30 degree Celsius.On casing 15 walls noise reduction sound and insulation material are housed.The automatic control of this equipment is from heat detector 18, and heat detector can be placed to reach the purpose of automatic control indoor on demand by the comfortable requirement of constant temperature.Heat detector is a temperature-sensitive element, and its operation principle is: drive external magnet m when rotation turn-knob 16 and rotate, drive upper and lower the moving of upper contact " a " in the vacuum tube.Following contact " b " is conductive mercury, utilizes the cold and hot expansion realization " a " of mercury and the open and close of " b ".Temperature-sensitive element also can adopt Switzerland product HERT840 control instrument.
