Abstract
The utility model relates to a frequency conversion and energy saving device, in particular to a ground air suction air conditioner frequency converter, which comprises a fan motor and a circuit breaker and is characterized in that the fan motor is connected with a frequency conversion control cabinet through a conducting wire. The ground air suction air conditioner frequency converter has the beneficial effects of adjustable rotating speed of a fan, energy saving and electricity saving, is simple to operate and convenient and safe to use and is suitable for being used for cleaning shops.
Description
Technical field
The utility model relates to a kind of frequency converting and energy saving device, specifically is a kind of ground air draught air-conditioning converter plant.
Background technology
Weave the air-conditioning that uses in the workshop at present and drive flabellum as the blower fan of 45Kw and rotate, utilize air in the air channel, circulate to reach purpose to workshop cleaning flower mao.Because the blower fan that uses all adopts the control mode of star triangle start, load was lighter when air-conditioning draught fan was normally opened, do not need running at full capacity can allow air reach in the air channel circulation and clean the purpose of spending hair, along with the increase of rotating speed, all blower fan runnings at full capacity have caused the electricity consumption waste.
Summary of the invention
The utility model provides a kind of energy saver of frequency control in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
The utility model comprises blower motor and circuit breaker, and its special character is: described blower motor connects the variable frequency control cabinet by lead.
Circuit breaker described in the utility model is arranged on the input of variable frequency control cabinet.
Variable frequency control cabinet power supply described in the utility model adopts three-phase 380V voltage input unit circuit.
Ground of the present utility model air draught air-conditioning converter plant, with the control device complete removal that uses in the past, install additional and be the variable frequency control cabinet, replace the method that original star triangular pattern starts blower motor, reach the purpose of direct control motor speed by the frequency of adjusting frequency converter.Because blower fan is a kind of plant equipment that transmits gas that the shaft power of motor is changed into air quantity mechanical energy, so learn from fluid mechanics principle, fan delivery is relevant with motor speed power promptly: fan delivery is directly proportional with rotating speed of motor, the shaft power of blower fan be directly proportional with the quadratic power of the rotating speed of blower motor (being that fan shaft power is directly proportional with the quadratic power of frequency of supply).Frequency with frequency conversion under the normal condition is adjusted into 45Hz by 50HZ, has only 72.9% of the past by the power output that calculates on the motor shaft, and power saving rate is 27.1%.
The beneficial effect of ground of the present utility model air draught air-conditioning converter plant is: simple to operate, easy to use, safe, rotation speed of fan is adjustable, and energy saving relatively is applicable between cleaning cart.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1, blower motor, 2, the variable frequency control cabinet, 3, lead, 4, circuit breaker.
Embodiment
Also in conjunction with the accompanying drawings the utility model is further described below by embodiment;
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises blower motor 1, and blower motor 1 connects variable frequency control cabinet 2 by lead 3.
Ground of the present utility model air draught air-conditioning converter plant, the employing three-phase voltage is that the power supply of 380V is transmitted electricity to circuit, after the close circuit breaker 4, whole install electric operation, become 45HZ by regulating Frequency Converter Control cabinet 2 frequencies by 50HZ with air-conditioning draught fan motor 1, reach the purpose that reduces rotation speed of fan, the interior among a small circle simultaneously rotating speed that changes blower motor 1 does not influence the cleaning effect of blower fan, frequency with frequency converter under the normal condition is adjusted into 45Hz by 50HZ, has only 72.9% of the past by the power output that calculates on the motor shaft, power saving rate is 27.1%, so adopt this converter plant energy-saving effect obvious.In addition, by site inspection wind wheel is installed after, the frequency of frequency converter is become 35HZ by 41.8HZ, do not change wind speed substantially, also can reach normal cleaning, energy-conservation effect.
Claims (3)
