Old-fashioned air conditioner electric auxiliary heating system, control method and air conditioner comprising old-fashioned air conditioner electric auxiliary heating system

Abstract

The invention discloses an electric auxiliary heating system for an old-fashioned air conditioner. The electric auxiliary heating system comprises a first relay, a second relay, a temperature limiter, an electric auxiliary heating part, a heat blown fuse, reversing valve current, inner draught fan current and other components. A hot wire is connected with the input end of the first relay. The control end of the first relay is connected with the reversing valve current. The output end of the first relay is connected with the input end of the second relay. The control end of the second relay is connected with the inner draught fan current. The output end of the second relay is connected with one end of the temperature limiter, and the other end of the temperature limiter is connected with one end of the electric auxiliary heating part. The other end of the electric auxiliary heating part is connected with one end of the heat blown fuse. The other end of the heat blown fuse is connected with a zero wire. The electric auxiliary heating system has the effects of low power consumption, high safety and low cost. The invention further discloses an electric auxiliary heating control method and the air conditioner, and potential safety hazards caused by overheat of the electric auxiliary heating part 4 can be effectively prevented through the temperature limiter and the heat blown fuse.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an electric auxiliary heating system for an old air conditioner. Background technique [0002] With the improvement of people's living standards, air conditioners are used more and more frequently in daily life. Most old-fashioned air conditioners are only designed with cooling effect in summer, and their heating effect is insufficient. If the air conditioner is replaced only to improve the heating effect, it will inevitably cause waste. [0003] To solve this problem, many solutions have been proposed: [0004] CN201310502825.9 proposes to use carbon fiber heating method, using light wave heat transfer, its disadvantages are high production cost, and the quartz tube is easily damaged. [0005] CN201320823002.1 improves the existing electric auxiliary heating device, but it still has the disadvantages of complex structure and low energy saving effect. Contents of the invention [0006] ...
