Static thermal-storage heating-amount slow-release structure and construction process and use thereof

Abstract

The present invention relates to a geothermic electric heating static heat-stored heating heat quantity slowly-releasing structure, its construction process and application. Its structure comprises up-down laminated heat-storing layer and heat quantity slowly-releasing layer, the geothermic cable is embedded in the heat-storing layer formed from heat-storing material whose heat-conducting coefficient is 0.3-0.79w.m(-1).k(-1), said heat-storing layer is covered with the slowly-releasing layer formed from slowly-releasing material whose heat-conducting coefficient is 0.04-0.07 w.m(-1).k(-1), and the temp. sensor is embedded in the slowly-releasing layer, and is series-connected with geothermal cable loop. Its application includes the following steps: starting power supply to supply power to geothermic cable, and storing heat energy in heat-storing layer, then slowly-releasing the heat energy to heating space by means of slowly-releasing layer.

Description

Technical field [0001] The invention relates to electric heating technology, in particular to a geothermal electric heating static heat storage type heating heat slow release structure and its construction technology and application. Background technique [0002] The existing electric heating technology still has some imperfect aspects: [0003] 1. Most of them use electric radiators, electric heaters, and electric water heaters for direct heating. The comprehensive energy utilization efficiency is low, only 30%; in addition, warm air is used for heating. When blowing at close distances, people will be suffocated due to too much heat. When the distance is far away, it will become cold due to heat dissipation and air exchange, and the comfort of indoor personnel is poor (factors affecting comfort are temperature, air pressure, humidity, wind speed, etc.); [0004] 2. The low-cost but simpler technology of electric heating film ceiling radiant heating is poor in comfort and safety,...

Problems solved by technology

[0003] 1. Most of them use electric radiators, electric heaters, and electric water heaters for direct heating, and the comprehensive energy utilization efficiency is low, only 30%. In addition, warm air is used for heating. When the distance is long, cold wind is formed due to heat dissipation and air exchange, and the comfort of indoor personnel is poor (factors that affect comfort include temperature, air pressure, humidity, wind speed, etc.);

[0004] 2. The electric heating film ceiling radiation heating with low cost but relatively simple technology has poor comfort and safety, and the surface temperature of the radiator exceeds the national standard;

[0005] 3. Household central air-conditioning technology of air heat pump, the heating capacity is limited by temperature, which has adverse effects on the environment;

[0006] 4. Groundwater electric heat pump heating, which uses low-temperature heat exchange technology to pump out groundwater and use its heat energy. Although the conversi
