Temperature-humidity and differential pressure transducer of machine room air-conditioning set

Abstract

The invention relates to the technical field of the sensor, especially to a temperature-humidity and differential pressure transducer of a machine room air-conditioning set. According to the temperature-humidity and differential pressure transducer, a differential pressure transducer and a temperature-humidity sensor are integrated, thereby realizing simultaneous monitoring of a rotating speed of a fan, a filer screen cleanliness, and a temperature and humidity in a machine room. Meanwhile, with regard to a circuit design of a temperature-humidity collection chip, board arrangement is carried out at the periphery of the temperature-humidity collection chip in a slotting mode and no copper is laid, so that the influence on the collection chip by heating of other elements can be avoided and precise temperature and humidity sampling can be realized; and the accurate feedback can be provided for the control system. According to the invention, the usage and installation of the client can be simplified effectively; all signals needed for machine air conditioner controlling can be provided accurately and effectively during the operation process. Besides, the using cost the client can be lowered and the client experience can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a temperature, humidity and pressure difference sensor for an air conditioner unit in a computer room. Background technique [0002] Computer room precision air conditioner is a special air conditioner designed for modern electronic equipment room. Its working accuracy and reliability are much higher than ordinary air conditioners. Computer equipment and program-controlled switch products are placed in the computer room, which is composed of a large number of dense electronic components. To improve the stability and reliability of these devices, it is necessary to strictly control the temperature and humidity of the environment within a specific range. The precision air conditioner in the computer room can control the temperature and relative humidity of the computer room in a stable range, thus greatly improving the service life and reliability of the equipment. In order to co...

Problems solved by technology

[0004] However, the differential pressure sensor and the temperature and humidity sensor are two different products; the temperature and humidity sensor generally adopts the method of directly sampling the capacitance value, and the sampling accuracy is low; the differential pressure generally adopts a differential pressure switch with digital output, which provides less information , which requires the control terminal to provide multiple sampling ports, and the installation method is complicated
