Benefits of technology
The present invention provides a variable frequency control apparatus that can be added to a constant frequency air-conditioning system, allowing for easy installation and operation. This apparatus provides the benefits of variable frequency operation, such as improved efficiency and flexibility, without the need for a separate variable speed system.
Problems solved by technology
With technological progress and cultural development, most industrial developments and economic activities consume a large quantity of energy, and the consumption of energy in any form will cause environmental pollutions.
Wherein, air-conditioner that providing an air-conditioning effect is an electric appliance that consumes lots of electricity and a compressor of the air-conditioner is the main cause of the high power consumption of the air-conditioner.
Since the compressor has only two modes, respectively ON and OFF, therefore the frequent switching between ON and OFF and the higher current required for starting the compressor result in high power consumption.
In some situations, the user may even need to change the interior decoration in order to fit the shape and size of the new equipment, and thus incurring additional cost for a large-scale remolding and lowering the consumer's willingness of changing to the variable frequency air-conditioning equipment.

A variable frequency control apparatus includes a variable frequency controller, and at least one temperature sensor, and the variable frequency controller is installed at a compressor of an air-conditioning equipment and electrically coupled to the compressor, and the temperature sensor is installed at a position where a refrigerant pipeline passes through the compressor. A temperature change of the refrigerant passing through the compressor is used as a basis for determining whether an air-conditioning host of the air-conditioning equipment situated in an indoor space has reached a predetermined air-conditioning effect, so as to control and adjust a rotational speed of the compressor and drive the compressor of a constant frequency air-conditioning equipment to produce a variable frequency operation effect.
Description
FIELD OF THE INVENTION[0001]The present invention relates to a variable frequency control apparatus, in particular to the variable frequency control apparatus that is added to the application of a constant frequency air-conditioning equipment, so that a compressor of the constant frequency air-conditioning equipment has the effect of variable frequency operations.BACKGROUND OF THE INVENTION[0002]With technological progress and cultural development, most industrial developments and economic activities consume a large quantity of energy, and the consumption of energy in any form will cause environmental pollutions. As the awareness of environmental protection arises and international energy environmental conditions vary, finding a way of saving energy and improving energy efficiency becomes an issue of global concern to overcome the problems of the greenhouse effect, the trend of high-priced energy sources and the depletion of traditional energy sources.[0003]Wherein, air-conditioner ...
