The invention provides a heating system applied to an air conditioner. The heating system comprises a thyristor and a resistive load. The thyristor comprises a heating circuit, a control circuit whichis used for controlling the on-off frequency of the heating circuit, and a signal terminal which is connected with the control circuit. One end of the heating circuit is connected with a power supply, and the other end is connected with the resistive load. The signal terminal is used to input a heating proportional adjustment signal. The control circuit controls the on-off frequency of the heating circuit through the input heating proportional adjustment signal. According to the invention, the signal terminal of the thyristor receives the input heating proportional adjustment signal to adjustthe on-off frequency of the heating circuit; the heat output of the resistive load is controlled with high accuracy to carry out heating; and a number of components of original hierarchical heating are eliminated, which saves cost, realizes high-accuracy heating capacity control, and saves energy.
Description
technical field [0001] The invention relates to an air-conditioning technology, in particular to a heating system for air-conditioning. Background technique [0002] The heating system of traditional air conditioners is generally controlled in sections, and the heat is put into the corresponding heating section according to the demand, that is, several gears are set, and the corresponding gear is switched according to the demand. In this way, there is a misunderstanding in the heat input of the air conditioner heater, and the heating cannot be controlled with high precision, and the demand for high-precision heating cannot be met. Moreover, multiple control points are required for staged heating, and a first-level line contactor at the control point is added, resulting in high control costs and high energy consumption. [0003] Therefore, there is an urgent need for a heating system with a high-precision heating function. Contents of the invention [0004] Aiming at the ...
