Abstract

The new composite phase changing heat accumulating heating technology includes adding heat accumulating pipe and heat accumulating capsule into traditional electric heating set and filling heat medium in the gaps. The heat accumulating medium takes phase change while being heated and cooled to form one latent heat accumulating process. The heat medium acts as the fluid medium for heat transfer between the heated surface and the heat accumulating medium to strengthen the heat transfer inside the heat accumulating medium on one hand, and takes temperature change as one sensible heat process accompanying the heat accumulating and releasing on the other hand. The technology of the present invention can strengthen the heat transfer process inside heat accumulating medium, raise heat accumulating capacity and decrease size of heat accumulating apparatus.

Description

technical field

[0001] The invention relates to a phase-change heat storage heating method and a heating pipe section in electric heating and floor electric heating, belonging to a residential heating method and system. Background technique

[0002] Heat storage technology is an important technology to improve energy utilization efficiency and environmental protection. It can be used to solve the rationing contradiction between heat energy supply and demand, and has become a research hotspot worldwide. With the improvement of people's living standards, more and more electrical appliances have entered the homes of ordinary people, and the frequency of use of most of these electrical appliances has dropped sharply after the early morning. This makes the original very serious "peak-valley" contradiction of power supply more prominent, and the difference between peak power consumption and low power consumption load is getting bigger and bigger. The continuous increase of the pe...
