Ionic solution three-cycle coupling low-temperature heat supply system and using method

Abstract

The invention relates to an ionic solution three-cycle coupling low-temperature heat supply system and a using method. The ionic solution three-cycle coupling low-temperature heat supply system comprises a low-temperature heat collection subsystem, a heat pump energy supply subsystem and an enthalpy increasing regeneration subsystem. The low-temperature heat collection subsystem is provided with an ionic solution heat collection circulation loop, and the heat pump energy supply subsystem is provided with an ionic solution energy supply circulation loop. And the enthalpy increasing regeneration subsystem is provided with an ionic solution regeneration circulation loop. The low-temperature heat collection subsystem and the enthalpy increasing regeneration subsystem are communicated with each other through the ionic solution regeneration circulation loop, and the enthalpy increasing regeneration subsystem supplies and conveys a regenerated ionic solution to the low-temperature heat collection subsystem through the ionic solution regeneration circulation loop. The low-temperature heat collection subsystem and the heat pump energy supply subsystem are communicated with each other through the ionic solution energy supply circulation loop, and the low-temperature heat collection subsystem transfers heat to the heat pump energy supply subsystem through the ionic solution energy supply circulation loop. According to the ionic solution three-cycle coupling low-temperature heat supply system and the using method, a small amount of electric energy is input through a heat pump unit, and thus low-temperature heat energy below the freezing point can be transferred to the high-temperature position. And the requirements of building heating and heat supply are met.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to an ion solution three-circulation coupled low-temperature heating system and a use method. Background technique [0002] With the rapid development of my country's economy and irregular climate changes, the demand for heating and heating in the "low temperature and high humidity" areas in the south will gradually increase. Due to the unscientific traditional heating methods, low energy efficiency of equipment, and unreasonable use of energy, it has been criticized. Great waste, low temperature heating technology came into being. [0003] In view of the climate characteristics of low temperature and high humidity in southern my country in winter, the air contains a large amount of low-level heat energy converted from solar energy. Due to the high wet bulb temperature, the low-grade energy storage in the air is huge, but the low-level heat energy below freezing point is po...
