Automatic precise temperature control system and method

Abstract

The invention discloses an automatic precise temperature control system and method. The system comprises a heat exchanger and a controller, wherein a bypass pipeline is arranged between a pipeline between a pipeline pump and an adjusting valve set and a pipeline between a power high-temperature water inlet and the heat exchanger in a penetrating mode, a temperature sensor is arranged at the hot air position, the temperature sensor is electrically connected with the controller, and the controller is electrically connected with an adjusting valve set. The method comprises the steps that 1, heat exchange is carried out, specifically, cold air on one side is subjected to heat exchange through the heat exchanger, the temperature rises, and the cold air is converted into hot air; 2, precise temperature control is carried out, specifically, the temperature sensor senses the air temperature of the hot air, and transmits a temperature signal to the controller, and the controller compares the sensed temperature with the set temperature, so that the temperature of air outlet of the air conditioner can be controlled more accurately, air conditioner air with stable temperature, high precision and small deviation is obtained, and the spraying effect of an automobile body is better.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment for automobile painting process, and the specific field is an automatic and precise temperature control system and method. Background technique [0002] With the continuous advancement of science and technology and the continuous improvement of people's living standards, people have higher and higher requirements for the appearance quality of automobiles. In the spray booth of the automobile production line, the surface of the workpiece is sprayed with a high-quality paint film, and the temperature and humidity parameters of the spray paint environment are particularly important. [0003] In order to continuously provide clean air during the spraying process of the automobile body, an air conditioner is required. However, the traditional air conditioner is only designed with a large-caliber electric regulating valve to control the hot water flow, which will make the final output...

Problems solved by technology

[0003] In order to continuously provide clean air during the spraying process of the automobile body, an air conditioner is required. However, the traditional air conditioner is only designed with a large-caliber electric regulating valve to control the hot water flow, which will make the final output of the air conditioner The air temperature and accuracy cannot be precisely controlled, which makes the air outlet temperature of the air conditioner unstable and the accuracy is poor, which makes it impossible to maintain a suitable spraying environment indoors and makes the quality of the paint film sprayed on the surface of the workpiece poor. For this reason, we provide a Automatic and precise temperature control system and method
