Temperature control device with high control precision

Abstract

The invention discloses a temperature control device with high control precision, comprising a power module, a processor module, a display module, a communication module, a temperature sensor, a button module, a heat sensing module and a heat insulation layer. The processor module computes signals from the temperature sensor, the button module and the communication module, then transmits the signals to the display module for display, and transmits a computed control signal to an air conditioning control system. The heat sensing module includes a tubular measuring portion capable of accommodating the temperature sensor and a plate-shaped heat collecting portion. One end of the measuring portion is fixed to the plate-shaped heat collecting portion. The temperature sensor is installed in themeasuring portion. The heat insulation layer and the plate-shaped heat collecting portion are attached to each other and are disposed on a side of the measuring portion. The heat sensing module has large heat exchange area with the air to be tested, high heat transfer efficiency, improves room temperature detection accuracy, reduces room temperature fluctuation, and further shortens temperature control response delay. The heat insulation layer reduces the influence of the heat generated by the control circuit on accurate temperature measurement.

Description

technical field [0001] The invention relates to a temperature control device, in particular to a temperature control device with high control precision and not affected by the self-heating of a control circuit, belonging to the field of temperature control. Background technique [0002] The indoor temperature maintained by the air-conditioning system often fluctuates frequently and greatly, hot and cold, making people feel extremely uncomfortable, and sometimes may affect people's health. The large fluctuations in the indoor temperature of the air conditioning system are mainly caused by the temperature control device, and the temperature sensor of the temperature control device and its temperature sampling method determine the control timeliness and control accuracy during temperature control, which in turn affects people's comfort to the temperature feel. [0003] The temperature sensor of the traditional temperature control device is often installed in the casing of the ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a temperature control device with high control accuracy, which is used to solve the problems in the prior art: the temperature sensing area of ​​the temperature sensor is small, and it is easily caused by the flow of the measured air flow with uneven temperature distribution. The temperature of the detection point fluctuates; the opening of the temperature controller shell causes poor air flow around the temperature sensor, resulting in a slow temperature response time; the heat generated by the electronic components on the circuit board inside the temperature control device causes the temperature sensor to detect The temperature drifts and the room temperature cannot be accurately measured
