Floor heating water temperature control method and system

Abstract

The invention provides a floor heating water temperature control method and system. The method comprises the following steps that floor heating parameters are collected and comprise the floor material, the floor thickness and the floor heating pipe distributing distance; the water supply temperature is calculated according to the formula: T=Tc*m+(H-60)*T1-d*T2+C, and the floor heating is controlled for heating according to the water supply temperature; after the floor heating runs the preset first heating time according to the water supply temperature calculated in advance, the temperature difference of floors is detected; the indoor temperature difference between the indoor environment temperature and the preset indoor environment temperature is detected; and according to the floor temperature difference and the indoor temperature difference, the indoor temperature difference correction value and the floor material limitation factor are optimized, and the step of calculating the water supply temperature is executed repeatedly. Different water supply temperatures can be automatically set according to different materials, the temperature rising rate and the indoor comfort degree of the floors are guaranteed, the floors are prevented from being heated rapidly so that cracking can be prevented, and it is also prevented that temperature rising is low while the heating time is too long; and the indoor temperature difference correction value and the floor material limitation factor are optimized constantly, the indoor environment is more comfortable, and more energy is saved.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to a ground heating water temperature control method and system. Background technique [0002] Floor heating has the advantages of energy saving and high indoor comfort, and is being widely used for indoor heating in winter. However, due to the unique thermal inertia of the floor, and different floor materials, the thermal inertia presented is different, making floor heating different from ordinary air-conditioning heating. Traditional floor heating uses water supply temperature as the control object, and the water supply temperature is only set by the user. This kind of control has the following disadvantages: if the set water supply temperature is too high, the floor temperature will be too high and crack, and there are disadvantages of discomfort and no energy saving; if the set water supply temperature is too low, the floor temperature rises too slowly, The heating time is too...
