Phase change energy storage heat exchange device

Abstract

The invention discloses a phase change energy storage heat exchange device, and relates to the technical field of heat exchange equipment. The phase change energy storage heat exchange device comprises an electric heating box, the heat source output end of the electric heating box is connected with a water inlet pipe of a first energy storage device through a first heat storage control valve, thefirst energy storage device is provided with a water outlet pipe, and the water outlet pipe is connected with two heat source output pipelines. One heat source output pipeline is connected with the heat source input end of the electric heating box through a heat conduction oil pump and a second heat storage control valve, the other heat source output pipeline is connected with the heat source input end of a fan coil after passing through the heat conduction oil pump, a second heat release control valve and a second energy storage device, and the output end of the fan coil is connected with theheat source input end of the first energy storage device through a first heat release control valve. According to the phase change energy storage heat exchange device, phase change heat exchange energy storage can be achieved through off-peak electricity.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a phase change energy storage heat exchange device. Background technique [0002] The northern part of my country has a vast territory, and the heating energy consumption in winter is huge. In recent years, the country has advocated energy conservation and green development, and banned and rectified various boilers with huge energy consumption and serious pollution. Most of the various types of boilers on the market have limited thermal efficiency and low thermal utilization rate, and part of the heat energy is wasted. Therefore, it is very necessary to recover the waste heat of the boiler. The maximum use of the waste heat of the boiler is used to increase the convenience of heating and domestic hot water, which is of great significance to save energy. And in order to save energy, the government encourages enterprises and individuals to use electricity at off-pe...
