Experimental Study on the Solar Energy and Pebble Thermal Storage Technology for Storing Heat

Abstract:

Solar energy heating technology has a widely used in the construction, The main obstacle in applicationis how to make solar energy become the continuous and steady source of heat, to ensure all-weather continuous heating, the key is how to store and release the heat energy collected by the solar collector slowly. Ningxia yinchen solar energy technology limited company combine the solar collectors and underground pebble heat storage layer, used it in single-layer local-style dwelling houses in the countryside, Through the field test, the system can keep a very stable indoor temperature throughout in Sunny days when the outdoor temperature was minus 10 °C above, there has enough heat storage capacity to meet the requirements of indoor heating at a two cloudy days after sunny, but if More than 3 days are cloudy, auxiliary heating should be carried out using auxiliary heat source. The experimental results show that this method is simple and regenerative effect is significant.
