A kind of humiture independence control air conditioner system of Driven by Solar Energy
Technical field:
The invention belongs to field of air conditioning, are related to a kind of solar air-conditioner system more particularly to a kind of temperature of Driven by Solar Energy Humidity independent control air-conditioning system.
Background technique:
Prediction industrial research institute " 2013-2017 China's intelligent building industry market prospect and investment strategy planning application Report " data shows, the building energy consumption in China in energy wastage in bulk or weight shared by ratio had increased to 27.45%.HVAC Air conditioning energy consumption accounts for 60% or more of building total energy consumption again, and building energy conservation emission reduction has become the energy problem of urgent need to resolve.2006 Year, country promulgated " People's Republic of China's Renewable Energy Law ", advocates utilize renewable energy energetically, increased energy resource supply, Realize the sustainable development of economic society.Common renewable energy includes solar energy, water energy, wind energy, tide energy etc..In view of wind The regional disparity and unstability of the renewable energy such as energy, water energy, are difficult to efficiently use and promote in building energy conservation, and the sun Can be widely distributed, it is resourceful, it is inexhaustible.According to calculating, the solar energy total amount that ground is reached in 1 year is converted into Standard coal still about 1.892 × 1017T is 10,000 times of current world's main energy sources proved reserves, relies on these advantages, solar energy Development and utilization have extremely wide prospect.In the epoch of energy shortage now, national governments all utilize solar energy resources Important content as National Sustainable Development Strategies.
Traditional air-conditioning system, allows air by the cold surface lower than its dew-point temperature, i.e. dehumidification by condensation mode (uses 7 DEG C chilled water) realize cooling and dehumidification treatments to air, while remove building sensible heat load and latent heat load it is (wet negative Lotus).Cooling requires dry-bulb temperature of the sink temperature lower than air, and dehumidification requirements sink temperature is lower than the dew-point temperature of air, accounts for More than half sensible heat load of total load originally can be drained using high temperature cold source, but share 7 DEG C of low temperature cold source together with dehumidifying It is handled, causes the waste in energy utilization grade.Air is cooled down and dehumidified by dehumidification by condensation mode, is inhaled The sensible heat of receipts can only change in a certain range with latent heat ratio, and Building Indoor Environment adjust required for heat moisture ratio compared with Variation in big range.Moreover, the moist surface that dehumidification by condensation mode generates becomes the good of the biological pollutants such as mould breeding Place seriously affects indoor air quality.
The humiture independence control air conditioner system that hundred million academician of Tsinghua University river proposes adjusts new rheumatism using the method for dehumidifying Load is reduced the sensible heat load of air using the method for refrigeration, the separately adjustable of temperature and humidity is realized, in energy saving of system and heat Theoretical breakthrough is realized in terms of pleasant climate.Humiture independence control air conditioner system, refrigeration use high temperature cold source, can be improved System energy efficiency reduces energy expenditure, and dehumidification process can strengthen the processing to air quality, reduces room air pollution.This is System can overcome traditional air-conditioning system, and energy consumption is high, comfort is poor, the disadvantage of regulation performance difference.
But the humiture independence control air conditioner system applied at present mostly uses: steam compression type refrigeration mode+condensation It dehumidifies (or solution dehumidification), however it remains the big disadvantage of energy consumption.The present invention breaks through conventional thought, by absorption refrigeration system System is merged with solution dehumidification system, forms humiture independence control air conditioner system, the two subsystems belong to absorption Therrmodynamic system, can use heat-driven, and the present invention uses the Driven by Solar Energy air-conditioning system.Meanwhile the air-conditioning system is in heat Use aspects use the energy saving form such as temperature gradient utilization, recuperation of heat as far as possible, improve efficiency of energy utilization.
The Chinese patent of application number 201520621166.5 discloses a kind of solar energy solution dehumidification independent temperature-humidity control Air-conditioning system, the air-conditioning system is only with Driven by Solar Energy solution dehumidification module, thus achieve the purpose that humidity handling, it is empty The part (sensible heat processing) of gas Temperature Treatment does not use Driven by Solar Energy, and form is simple with structure, can not formation temperature Cascade utilization, building energy conservation effect are not obvious enough.The present invention also adopts coupled system other than the reinforcing to solar energy utilizes With temperature gradient utilization, air-supply and return air form to user room are designed, and enhance recuperation of heat utilization.
Summary of the invention:
The purpose of the present invention is to provide a kind of humiture independence control air conditioner systems of Driven by Solar Energy, use temperature Gradient utilizes and the power save modes such as recuperation of heat, and building energy conservation effect is obvious, the thermal comfort height in user room, air quality Height, the shortcomings that traditional air-conditioning system can be overcome.
