Abstract
The utility model provides an energy-saving central air-conditioner. The energy-saving central air-conditioner is characterized by comprising a central air-conditioner, a conditioner air supply joint, a conditioner air return joint, a conditioner air supply pipe, a conditioner air return pipe, a central control board disposed on the air-conditioner, and a remote control computer. The central control board is connected with the remote control computer. An air speed detector is disposed at the air supply joint of the central air-conditioner. A blower connected with a frequency converter is arranged behind the air supply joint. Both the air speed detector and the frequency converter are connected with the central control board. The energy-saving central air-conditioner has the advantage that energy saving is achieved by adjusting blower speed to decrease power consumption when blower power is fixed.
Description
Technical field
The utility model relates to a kind of air-conditioning, especially relates to a kind of energy-saving air central.
Background technology
The nineties is for " simple frequency conversion " the product but cause the failure of large multiproject because of its limitation of the central air-conditioning circulatory system.In recent years, although can solve some basic problems for the equipment of specific project exploitation, because of its " simple frequency conversion " theory that remains of continuing to use, do not find the key of central air-conditioning energy.Cause that fractional energy savings is low, system is with strong points, the layman can't grasp, the excessive outstanding problem of investment maintenance cost, therefore most projects the phenomenon such as can not use.
Reducing energy consumption in central air-conditioning early stage or the central air-conditioning operational energy efficiency that is moving provided precise information and lay a good foundation.Thereby the operational efficiency to energy saving of system potentiality or system has a whole understanding.Provide and carry out targetedly reducing energy consumption or system is carried out the energy-saving effect assessment.
By hydrodynamics as can be known, P (power)=Q (flow) * H (pressure), flow Q is directly proportional with the first power of rotational speed N, square being directly proportional of pressure H and rotational speed N, cube being directly proportional of power P and rotational speed N is if the efficient of blower fan is certain, when requiring adjust flux to descend, rotational speed N can proportionally descend, and this moment, shaft power P became cubic relationship to descend.The power consumption that is blower motor is approximated to cube relation of ratio with rotating speed.For example: an air-conditioning unit power of motor is 55KW, when rotating speed drop to former rotating speed 4/5 the time, its power consumption is 28.16KW, power saving 48.8%, when rotating speed drop to former rotating speed 1/2 the time, its power consumption is 6.875KW, power saving 87.5%.
Summary of the invention
Problem to be solved in the utility model provides a kind of energy-saving air central, utilizes in the efficient one that guarantees blower fan regularly, reduces the blower fan power consumption by adjusting rotary speed, thereby reaches energy-conservation purpose.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of energy-saving air central, comprise central air-conditioning, the interface of air-conditioning and return air and pipeline, be arranged on central control board and remote control computer on the central air-conditioning, described central control board links to each other with remote control computer, the air outlet place of described central air-conditioning arranges a wind speed detector, be provided with the pressure fan that links to each other with a frequency converter behind the air outlet, described wind speed detector, frequency converter all link to each other with central control board.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, utilization in the efficient one that guarantees blower fan regularly, reduce the blower fan power consumption by adjusting rotary speed, thereby reach energy-conservation purpose, this air-conditioning is reduced to the blower fan frequency between 30～40Hz, and expectation can be saved for air-conditioning 15%～30% electric power.Have simple in structure, the advantage such as energy-saving effect is obvious.
Description of drawings
Fig. 1 is structural representation of the present utility model
Among the figure:

4, pressure fan 5, frequency converter 6, central control board
7, remote control computer
The specific embodiment
As shown in Figure 1, the utility model comprises central air-conditioning 1, the interface of air-conditioning and return air and pipeline, be arranged on the central air-conditioning 1 central control board 6 and remote control computer 7, described central control board 6 links to each other with remote control computer 7, air outlet 2 places of described central air-conditioning 1 arrange a wind speed detector 3, be provided with the pressure fan 4 that links to each other with a frequency converter 5 behind the described air outlet, described wind speed detector 3, frequency converter 5 all link to each other with central control board 6.
The course of work of this example: the staff starts energy conservation economic operation mode by remote control computer 7, under the prerequisite that guarantees the return air humiture, central control board 6 is adjusted pressure fan 4 rotating speeds by control frequency converter 5 and is progressively reduced pressure fan 4 frequencies to minimum stationary value, central control board 6 is measured the air-supply wind speed by air outlet 2 place's wind speed detectors 3, minimum wind speed by will blow wind speed and setting compares, as the foundation of adjusting frequency converter 4 frequencies.
Above an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
