Embodiment Construction

[0032] The invention provides a method for controlling indoor temperature and humidity of a variable air volume air conditioner based on absolute humidity, comprising the following steps:

[0033] Step 1: Install the air-conditioning terminal equipment in the room 1 that needs to adjust the temperature and humidity. The air-conditioning terminal equipment includes the regulating air duct 2, and the electric damper 3 is installed on the regulating air duct 2. Adjust the air supply volume of the air pipe 2 to the indoor 1; through the control of the air supply volume, the indoor temperature is affected, so as to achieve the purpose of adjusting the indoor temperature.

[0034] The regulating air duct 2 is connected to the blower 11 in the central air conditioner, and the wind force of the blower 11 is introduced into the room; the air volume sensor 5 is installed in the regulating air duct 2, which is used to collect the current air volume in the regulating air duct 2; the system...

Abstract

The invention discloses a method for controlling the indoor temperature and humidity of a variable air volume air conditioner based on absolute humidity. Aiming at the working conditions in summer, the combined cascaded double closed-loop control is adopted for temperature and humidity control. The humidity control link changes the dew point of the air supply by adjusting the opening of the chilled water valve through the inner ring, and the outer ring adjusts the room humidity by changing the dew point setting value; the temperature control link realizes temperature control by adjusting the end air valve to change the air supply volume. In view of the coupling between relative humidity and temperature, absolute humidity is introduced for dehumidification at dew point. In view of the coupling phenomenon between the temperature and humidity control loops, different correction coefficients are introduced in the control loops for decoupling coordination, which realizes the unity of comfort and economical energy saving.

Description

technical field [0001] The invention belongs to the field of variable air volume air conditioning systems, in particular to indoor temperature and humidity control of variable air volume air conditioners, in particular to an indoor temperature and humidity method for variable air volume central air conditioning systems based on absolute humidity control. [0002] technical background [0003] Summer is the season with the most prominent energy demand for air conditioning systems, mainly due to the increase in ambient humidity and temperature. Humidity mainly affects the heat metabolism and water-salt metabolism of the human body. With the improvement of people's requirements for comfort, temperature and humidity control has become the key to air-conditioning in summer, and it is a research hotspot of air-conditioning scholars at home and abroad. In order to maintain an appropriate temperature and humidity in an air-conditioned room, dehumidification measures are required. Th...
