A solar-driven temperature and humidity independent control air conditioning system

Abstract

The invention discloses a temperature and humidity independent control type air-conditioning system driven by solar energy. The temperature and humidity independent control type air-conditioning system driven by solar energy comprises a solar heat collection module, an absorption type refrigeration module, a solution dehumidification module and a domestic water module. The solar heat collector module comprises a vacuum pipe solar heat collector, a heat storage water tank, a first circulating water pump, an auxiliary heat source and a second circulating water pump. The absorption type refrigeration module comprises a generator, a condenser, an expansion valve, an evaporator, an absorber, a first solution heat exchanger, a first solution pump, a water distributor, a water collector, a third circulating water pump, a capillary tube radiation type air-conditioning tail end, a fourth circulating water pump and a cooling tower. The solution dehumidification module comprises a regenerator, an exhaust fan, a first water-solution heat exchanger, a second solution pump, a second solution heat exchanger, an absorber, an air feeder, a second water-solution heat exchanger, a third solution pump, a total heat exchanger and a mixed air box. According to the air-conditioning system, the energy-saving forms such as temperature gradient utilization and heat recovery are adopted for multiple portions according to the principle, and the energy utilization efficiency is improved.

Description

Technical field: [0001] The invention belongs to the field of air conditioning, and relates to a solar air conditioning system, in particular to a solar energy driven temperature and humidity independent control air conditioning system. Background technique: [0002] According to the data from Qianzhan Industry Research Institute's "2013-2017 China Intelligent Building Industry Market Prospect and Investment Strategic Planning Analysis Report", the proportion of my country's building energy consumption in total energy consumption has risen to 27.45%. HVAC energy consumption accounts for more than 60% of the total energy consumption of buildings, and building energy conservation and emission reduction has become an energy problem that needs to be solved urgently. In 2006, the state promulgated the "Renewable Energy Law of the People's Republic of China", vigorously promoting the use of renewable energy, increasing energy supply, and achieving sustainable economic and social d...

[0006] The Chinese patent application number 201520621166.5 discloses a solar solution dehumidification temperature and humidity independent control air conditioning system. The air conditioning system only uses solar energy to drive the solution dehumidification module to achieve the purpose of processing air humidity. The part of air temperature treatment (sensible heat treatment) is not used. Driven by solar energy, the form and structure are simple, it cannot form a cascade utilization of temperature, and the energy-saving effect of the building is not obvious enough
