Abstract

The invention discloses a control method for temperature and humidity and an air conditioning system. The control method comprises the following steps of calculating an indoor load heat and humidity ratio according to the temperature and humidity and calculating a heat and humidity ratio according to a dehumidifying coefficient of a fan coiler; judging whether the heat and humidity ratio of the fan coiler is equal to the indoor load heat and humidity ratio or not; if not, adjusting the water inlet temperature of a heat exchanger to adjust the dehumidifying coefficient of the fan coiler till the heat and humidity ratio of the fan coil is equal to the indoor load heat and humidity ratio. By adjusting the water inlet temperature of the heat exchanger of the fan coiler to change the dehumidifying coefficient of the fan coiler till the heat and humidity ratio of the fan coil is equal to the indoor load heat and humidity ratio and changing the water inflow to change the refrigerating capacity of the fan coiler, the indoor temperature and humidity are controlled precisely, the energy consumption of the air conditioning system is reduced, and meanwhile, the comfort level of the human bodyis improved.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a temperature and humidity control method and an air conditioning system. Background technique [0002] During the selection process of the fan coil unit, designers often find that the cooling capacity is too large when selecting the type based on the air volume, but the air volume does not meet the design requirements when selecting the type based on the cooling capacity. Because the working environment of the fan coil unit is changing, and the humidity analysis factor of the fan coil unit does not change accordingly, the humidity analysis factor of the fan coil unit does not match the heat-humidity ratio of the indoor load, thereby affecting the indoor thermal comfort performance, reducing the efficiency of the air conditioning system. Contents of the invention [0003] In order to solve the technical problem in the prior art that the humidity analysis factor does not match t...
