Indoor electric heating film ground heating control device and indoor electric heating film ground heating control method

Abstract

The invention relates to the field of indoor ground heating control, in particular to an electric heating film heating control device and an electric heating film heating control method facing housing units. The invention provides an indoor electric heating film ground heating control device facing the housing units, which comprises a main temperature controller, a plurality of terminal temperature controllers and a plurality of temperature measurement probes, wherein the main temperature controller is mainly composed of a main control unit, a tactic storage unit, an electric heating film control unit, a temperature acquisition unit, a wireless communication unit, press keys and a display unit; and each terminal temperature controller is mainly composed of a main control unit, an electric heating film control unit, a temperature acquisition unit, a wireless communication unit, press keys and a display unit. According to the invention, under the premise of ensuring the heating comfort, the collaborative optimization control for power load of different heating rooms in a housing unit is realized, as a result, the heating load power of the whole housing unit is further reduced, the impact on the current electric network is effectively reduced, and the system can be used more easily.

Description

technical field [0001] The invention relates to the field of indoor floor heating control, in particular to an electrothermal film heating control device and control method for residential units. Background technique [0002] In recent years, electrothermal film heating has been widely concerned and welcomed by people because of its energy saving, long service life, simple management, safety and reliability, and has become the most potential indoor heating method. The existing electric heating film heating control method is mainly based on a single room, that is, a thermostat is installed in each room, and a temperature measuring probe is installed in the room and on the surface of the electric heating film respectively, so as to realize load control according to a predetermined temperature. This control method mainly has the following shortcomings, that is, each room is controlled separately, and it is very likely that each room will be heated at the same time. According to...

Problems solved by technology

This control method mainly has the following shortcomings, that is, each room is controlled separately, and it is very likely that each room will be heated at the same time. According to 100W / m 2 Design power calculation, an effective heating area of ​​80m 2 Residential units require an electrical load of 8000W, which has a greater impact on the existing power grid and may even cause local damage to the power grid

At present, some researchers have proposed some improvements. For example, the patent [CN201852191U] proposed a method of variable power control in the same heating space. The difficulty of installation and deployment has increased, and at the same time, a certain degree of comfort has been sacrificed, and the phenomenon of full-load work in each room has not been completely overcome; the patent [CN101858618A] proposes a heating cable heating control device for centralized heating of buildings. Furthermore, the automatic adjustment of heating cable power and the control of electricity consumption are realized, but because it adopts the method of temperature measurement by room, remote command and coordination, and centralized control by household, it is more suitable for the heating control of the entire community or the entire building. The system is difficult to implement and deploy, and the reliability is not high, especially if the remote control center fails, the entire controlled object will be out of control, while sacrificing a certain degree of user comfort
