Abstract

The invention relates to an integrated heating and heat exchange device based on step-by-step phase transition, comprising: a water inlet pipe, which is used to transport a heating medium to supply heat to a user terminal, and a temperature sensor is arranged inside the water inlet pipe to detect the heating medium temperature and send the detection result to the control unit; shell; phase change heat storage material, which arranges the phase change heat storage material along the flow direction of the heating medium and is movably connected with the water inlet pipe for storing and / or releasing heat, phase change A position sensor is arranged on the heat storage material to detect the moving position of the phase change heat storage material and send the detection result to the control unit; a driving motor is connected to the phase change heat storage material to adjust the position of the phase change heat storage material ; User terminal; Standby water pipe, which is respectively connected with the water inlet pipe and the user terminal, and is used to transport the heating medium to supply heat to the user terminal; Control unit, which is connected with the temperature sensor, the position sensor and the drive motor to receive detection data and control the operation of the device.

Description

technical field [0001] The invention relates to the technical field of central heating, in particular to an integrated heating and heat exchange device based on step-by-step phase transition. Background technique [0002] The urban central heating system consists of three parts: heat source, heat network and users. The heat source transfers heat to the primary pipe network through the heat exchange medium. The heat exchange medium can be high temperature steam or high temperature hot water. In the heat exchange station, the heat exchange medium of the primary network and the heat exchange medium of the secondary network exchange heat through the heat exchanger. The medium after heat exchange enters the secondary pipe network, and the heat exchange medium in the secondary network is high-temperature hot water, which is pressurized by a high-pressure pump and sent to the end of the user. The user terminal is generally divided into the following categories: radiator, floor rad...
