Abstract

The invention discloses an energy tower solution regeneration device based on a vacuum freezing method and a working method of the energy tower solution regeneration device, and relates to the technical field of energy tower heat pump air conditioning systems. According to the device, a refrigerating system involves a compressor, a condenser, a throttling valve and an evaporator; a heat supply system involves the condenser, a heat user, a fourth pump and a tenth electromagnetic valve; a solution regeneration system involves a dilute solution tank, the evaporator, a vacuum ice maker, a vacuum pump, a centrifugal desalting machine, a concentrated solution tank, an ice storage tank, a first pump, a second pump, a third pump, a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve, a fourth electromagnetic valve, a fifth electromagnetic valve, a sixth electromagnetic valve, a seventh electromagnetic valve, an eighth electromagnetic valve, a ninth electromagnetic valve and an eleventh electromagnetic valve. On the basis of a vacuum flash evaporation ice-making principle, the centrifugal desalting machine is adopted to enable salt-containing ice to beremoved from a lot of salt, and thus solution regeneration is completed. The device solves the problem of regeneration of solution of an energy tower heat pump unit, serves as an auxiliary heat source of the energy tower heat pump system, guarantees safe operation of the system and improves the comprehensive energy efficiency of regeneration of the energy tower solution.

Description

technical field [0001] The invention relates to an energy tower heat pump air-conditioning system, in particular to an energy tower solution regeneration device based on a vacuum freezing method. Background technique [0002] With the development of social economy and the continuous improvement of people's living standards, the requirements for the comfort of the working environment and living environment are also getting higher and higher, and the demand for heating is becoming more and more urgent. The middle and lower reaches of the Yangtze River belong to the region of hot summer and cold winter. The climate of this region is characterized by hot summer and cold winter, and the economy of this region is relatively developed, so the demand for building heating is particularly urgent. [0003] As one of the cold and heat source schemes of the central air-conditioning system, the air source heat pump is widely used in southern China because of its advantages of simple struc...
