Abstract

The invention provides a fan coil control method and system based on a PMV index, electronic equipment and a storage medium. The method comprises the steps that indoor environment parameters at the current moment are obtained; according to the indoor environment parameters at the current moment and preset parameters, the indoor environment PMV value at the current moment is calculated; the PMV deviation between the indoor environment PMV value at the current moment and the indoor PMV set value is calculated; calculating a PMV change value of the indoor environment PMV value at the current moment relative to the indoor environment PMV value at the previous moment; and according to the PMV deviation between the indoor environment PMV value at the current moment and the indoor PMV set value, the PMV change value of the indoor environment PMV value at the current moment relative to the indoor environment PMV value at the previous moment and the fan gear at the previous moment, the fan gear at the current moment is determined. According to the method and the device, the indoor PMV value can be maintained near the set PMV value, so that the indoor environment is maintained in a relatively comfortable state, and automatic switching of fan gears can be realized.

Description

technical field [0001] The invention relates to the technical field of fan coil control, in particular to a PMV index-based fan coil control method, system, electronic equipment and storage medium. Background technique [0002] The traditional HVAC system usually uses the indoor air temperature as the control parameter. According to the difference between the set indoor temperature and the actual temperature obtained by the temperature sensor, through the start-stop control, the PID controller and the fuzzy controller control the water temperature of the air conditioner. The system and wind system are regulated and controlled to maintain the temperature within the set range. Based on Fanger's thermal comfort theory, human comfort is mainly affected by environmental parameters such as indoor temperature, relative humidity, average radiant temperature, and wind speed, as well as personnel activity and clothing thermal resistance. Traditional air-conditioning systems use indoo...
