Method for measuring and controlling assembled air-conditioner dew point

Abstract

A method for measuring and controlling dew point temperature of integrated air-conditioning includes obtaining dew point temperature measurement value corresponding to temperature and relative humidity measurement value of control object point as well as dew point temperature setting value corresponding to temperature and relative humidity setting value, comparing obtained dew point temperature measurement value with obtained setting value, using proportional integration and differential algorithm to control aperture of valve in separating range for making said measurement value be gradually tended to said setting value.

Description

technical field The invention relates to a method for measuring and controlling the dew point temperature of an air conditioner, in particular to a method for measuring and controlling the dew point temperature of a combined air conditioner based on calculated dew point, which is specially used in a constant temperature and humidity system. Background technique With the rapid development of contemporary science and technology, industrial constant temperature and humidity air conditioners have been widely used, and higher requirements have been put forward for the high precision measurement and control technology and energy saving control technology of constant temperature and humidity air conditioners. Generally, the physical parameters often involved in air conditioning include: dry bulb temperature (T), relative humidity (RH), wet air pressure (P), dew point temperature (TW), moisture content (D), and wet air enthalpy (H) etc. For the large-scale combined air conditione...
