Temperature controller capable of realizing stepless speed adjustment

Abstract

The invention discloses a temperature controller capable of realizing stepless speed adjustment. The temperature controller comprises a single chip machine, a touch key input device, an infrared receiver, a temperature sensor, a wind speed controller, a communication module and a wireless communication module, wherein the infrared receiver receives signals from an infrared remote controller; the temperature sensor detects indoor temperature, detected temperature signals are transmitted into the single chip machine, in the single chip machine, detected temperature value is compared with the temperature value stored in the single chip machine, temperature difference value is figured out, the signal of the temperature difference value is transmitted into the wind speed controller by the single chip machine, and the input voltage of a fan is controlled via the wind speed controller; the communication module or the wireless communication module is connected with a server. The structure of the temperature controller capable of realizing stepless speed adjustment can realize stepless speed adjustment, remote control and wireless control, and the rotational speed of the fan can be automatically controlled according to the changes of room temperature. The temperature controller capable of realizing stepless speed adjustment is simple in the structure and low in cost, and the purposes of saving energy and reducing noise can be achieved.

Description

technical field [0001] The invention relates to a temperature control device for an air conditioner terminal device, in particular to a speed-regulating temperature controller for an ordinary fan coil unit, a brushless DC fan coil unit, and a variable air volume fan. Background technique [0002] The thermostat is an important functional element of the air-conditioning automatic control system. In the fan coil system and the variable air volume system, the main function of the thermostat is to control the indoor temperature by adjusting the air volume of the blower. At present, the thermostat of the air-conditioning terminal at home and abroad The main function is that the thermostat can set the speed of the fan to the third gear or adjust the gear manually. In addition, when the measured indoor temperature deviates from the set value, the cooling (hot) water supply to the coil can only be stopped by directly closing the electric valve. Its disadvantages are: poor energy sav...

[0002] The thermostat is an important functional element of the air-conditioning automatic control system. In the fan coil system and the variable air volume system, the main function of the thermostat is to control the indoor temperature by adjusting the air volume of the blower. At present, the thermostat of the air-conditioning terminal at home and abroad The main function is that the thermostat can set the speed of the fan to the third gear or adjust the gear manually. In addition, when the measured indoor temperature deviates from the set value, the cooling (hot) water supply to the coil can only be stopped by directly closing the electric valve. The disadvantages are: poor energy saving effect, large indoor temperature fluctuations, uncontrollable noise, and lack of remote control and remote wireless control functions

For the brushless DC fan coil unit, the excellent variable speed function of the DC motor cannot be fully utilized to further save energy
